Chapter 1 Introduction - 10 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy 1 Introduction 1.1 What Products are Covered by this Manual This manual covers the DataReader (both Indoor and Outdoor versions), Dat aSeal, Dat aT ag and the Magnet icDat aSeal product s. The DataTerminal, DataPort, MicroDataReader, T rackingDataReader and SmartDataReader are Hi-G-Tek products that are referred to in some places in t he manual, but are not covered by it. 1.2 About the Product Thank you for choosing Hi-G-T ek quality products. The Hi-G-Tek range of product s provides a highly reliable and secure cargo and asset monit oring system utilizing state-of-the-art RFID technologies. Cost-effective, more reliable and more secure than their mechanical counterparts, the Hi-G-T ek product range will constantly monitor your assets and alert you to any potential problems at all times. The Hi-G-Tek system was developed in order to fill the requirement for fast, automatic processing of secured cargoes and to provide real time monitoring and improved management of cargoes bot h in t ransit and in storage. The basis of the system is a family of reusable electronic seals named DataSeal. This family of product s includes t he Dat aSeal, Dat aT ag and t he MagneticDataSeal.
Chapter 1 Introduction Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 11 - Note: T his manual uses the term DataSeal to refer to any member of this family of product s, unless otherwise specified. The most significant purposes of the DataSeal are:  Track any attempts of opening, bypassing or tampering.  Record events when tamper occurs.  Write and read user data. The reusable electronic seal automates the processing of secured cargoes enabling the organization to effectively and economically process the increasing numbers of containers’ traffic in the ports and between inland destinations. The DataSeal includes a transmitter / receiver unit, real-time clock, processor, memory and sensing circuitry for sealing verification. The Sealing Wire1 prevents any attempt of opening, bypassing or tampering with the seal without alerting the system and recording of the event. The system combines the technological and operational advantages of both low frequency close-range AND high frequency (UHF) long range for sealing verification and other communications with the DataSeal. The low frequency (short range) communication protocol is used by the DataTerminal, the DataPort and the MicroDataReader. This channel of communication is useful for writing the electronic manifest of the sealed cargo into the DataSeal's memory. For example: this information can 1 In the c ase o f DataT ag, there's a “ Sensor Plate” instead o f the Sealing W ire, and in the case of the MagneticD ataSeal, there's a “ Magnet Element”.
Chapter 1 Introduction - 12 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy include the vehicle ID, container and invoice numbers, cargo description, etc. It is also useful for reading the DataSeal's event records, and to reset the DataSeal for a new use (an operation called "Set"). Note: The low frequency protocol, the DataTerminal, DataPort and MicroDataReader devices are not covered by this manual. The high frequency protocol is used by devices of the DataReader family of products. This family includes the DataReader itself, which connects to a controlling computer (normally a PC) through an RS-232/485 interface; the TrackingDataReader which contains a GPS and GSM modules and is usually installed on a truck; and the SmartDataReader which contains an embedded PC and connects to an Ethernet network. This manual covers only the Dat aReader device it self. The high frequency protocol is useful for monitoring the presence and status of one or more DataSeals constantly or periodically. It is capable of communicating with multiple DataSeals simultaneously and even with DataSeals in high speed motion, for example: on a train. The DataSeal and DataReader devices are capable of communicating in distances of up to 30 meters, and in some cases even more. The use of the high frequency/long range protocol enables applications such as: tracking and sealing verification of containers in transit; protection of containers in storage; remote automatic data collection from secured cargoes as they pass through check points, etc. The DataReader is able to detect which DataSeals are present in its area, and their statuses (open/close, tampered, etc). It can also receive messages from DataSeals in real-time, for example when the DataSeal is tampered. These types of messages that the DataSeal transmits are called "Burst Messages".
Chapter 1 Introduction Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 13 - Multiple DataReaders can be connected to a single controlling computer using the RS-485 interface. This allows to maximize the coverage area of the DataReaders while keeping them synchronized. The DataReader is available in both indoor and out door models. A set of Mount ing Fixt ures has been developed for the Dat aSeal syst em which allow convenient mounting and removal of the DataSeal from a cont ainer whenever required. The various Mount ing Fixt ures differ in t he level of protection they provide to the DataSeal as may be required in various environments.
Chapter 1 Introduction - 14 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy 1.3 System Components 1.3.1 The Mounting Fixtur e The DataSeal Mount ing Fixt ure is used to mount the DataSeal on the container’s keeper bar or other surface. 1.3.2 The DataSeal The DataSeal unit contains the DataSeal electronics, a battery, a transceiver, a processor and m emory t o reco rd and sto re t h e events and the relevant information about the cargo.
Chapter 1 Introduction Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 15 - 1.3.3 Sealing Wire The Sealing Wire serves to seal the cargo. Any tampering with the Sealing Wire at any point during transport is recorded and can be reported at once. 1.3.4 Outdoor DataReader The Hi-G-Tek DataSeal System uses st at e-of-t he-art t echnology to secure and monitor secured cargoes in storage and during transport. The DataReader is comprised of two compartments. The upper compartment is the heart of the unit and cont ains the DataReader’s electronics section. The lower compartment contains the terminal glands which connect
Chapter 1 Introduction - 16 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy the unit to the RS-232/485 networking cable. The DataReader may be used in both st at ionary and mobile configurat ions. In the stationary configuration, the unit is mounted on a flat surface such as a wall or pole. A typical installation of this configuration is at the point of exit from ports, customs terminals, warehouses, etc. This operation mode allows monitoring of the DataSeal at predetermined sites and checkpoints. In the mobile configurat ion, t he unit is mount ed in t he t ruck cabin. T he DataReader monitors the seal during the entire journey, and reports its status via the vehicle’s communication system to the control center in real-time. T his configuration requires an additional 3rd party controlling device to control the DataReader, or to use the TrackingDataReader which is not covered by this manual.
Chapter 1 Introduction Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 17 - The DataReader is mastered by a controlling computer. Once installed, the unit waits for commands coming from the controlling computer. 1.3.5 Indoor Dat a Re ad er Similar to the outdoor version, the Indoor DataReader uses state-of-the-art technology to secure and monitor secured cargoes in an indoor environment. The Indoor DataReader may be use d in stat ionary configuration only. The unit is mounted on a flat surface such as a wall or pole. A typical installation of this configuration is at the point of closed warehouses, offices, etc. Unlike the Outdoor DataReader, the Indoor version does not have the lower compartment. Instead it has 3 connectors.

Chapter 2 Quick Start - 20 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy 2 Quick-Start The aim of this chapter is to lead you step-by-step in the quickest way to the stage where you can verify that the Demo System is working properly, and that you have a simple syst em that you can play with, in order to evaluat e the potent ial of the product s. This guide a ssumes t hat t he parameters of the DataReader and DataSeal are the factory defaults, and it refers only to the Demo System. For installation instructions for a DataReader that is not a Demo System, see chapter 5. 2.1 Before you begin Before you begin, make sure that you have the following items available: 1. The Hi-G-Tek DataReader device. 2. DataReader Antenna. 3. At least one Hi-G-T ek DataSeal device. 4. The Seal ID of the DataSeal (printed on the sticker on the bottom side of the DataSeal). 5. Sealing Wire(s) (according to t he number of DataSeals. If you are using DataTags you need Sensor Plate(s) instead of the Sealing Wires) 6. P C running one of the following operat ing syst ems: • Windows 98 or above. • Windows NT 4.0 or above.
Chapter 2 Quick Start Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 21 - This computer must have at least one available serial communication port, a CD-ROM drive, and at least 20MB of free hard disk space. The computer must use an Intel PentiumTM or compatible processor. 7. CD-ROM with Evaluation Software. 2.2 Setting up the DataReaders First, connect the antenna to the DataReader. The antenna connects to the TNC connector at the top side of the DataReader. Then, connect the DB9 female connector to a serial communication port in t he PC. T ake not e of which port you are using (for example COM2). It is good practice to connect and disconnect cables only when the computer is off. Plug the power chord of the DataReader into a power outlet. You should see the POWER LED blinking red and green. After about 30 seconds it should remain green. If it remains red, or isn't lit at all, there is a problem with the DataReader. Refer to the chapter 0 for troubleshooting. 2.3 Installing the Evaluation Softw are If the computer is not turned on, turn it on now, and wait until the operating system is loaded completely. Insert the CD-ROM labeled "Hi-G-Tek" into the CD-ROM drive. From the Start menu, choose "Run". Assuming your CD-ROM drive is drive E, type "E:\DataSeal Evaluation Software\Setup.EXE" in the "Run" dialog box. If your CD-ROM drive lett er is not E, replace t he first E wit h your CD-ROM drive letter. Click OK to start installing the DataSeal Evaluation Software.
Chapter 2 Quick Start - 22 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy Follow the instructions on the screen until it says that the software is successfully installed. If you're using Windows 98, restart your computer (even if you're not requested to by the installation software). The Evaluat ion Soft ware is now inst alled. A new short cut icon " Dat aSeal Evaluat ion" is added t o your St art ->P rograms menu. 2.4 Configuring the System Run the Evaluation Software by clicking on that icon. The Re a de r s Administration Window shown in Figure 2-1 will be displayed.
Chapter 2 Quick Start Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 23 - Figure 2-1 - The Readers Administration Window. If you connected the Reader to a serial port other than COM1, choose the appropriate COM port from the Comm Port drop down list , and t hen click on the Se t Comm Port butt on. Click OK to close the message window that says "Comm port was set successfully". Click on the Au to De te ct button on the bottom of the window, to automatically find the Reader ID of the DataReader. The message shown in Figure 2-2 will be displayed.
Chapter 2 Quick Start - 24 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy Figure 2-2 - Auto Detect Warning Message. Because you're using the Demo System that includes only one DataReader, click Ye s . If everything is connected appropriately, a message window will appear saying "Reader was added successfully". Click OK to close this message. If instead of this message, a "T imeout" message appears, check your connections and verify that the communication port setting corresponds to t he one you're using. Remember t o click on Set Comm Port each t ime you change the communication port setting. If a different message appears, refer to chapter 9 for troubleshooting. The DataReader's ID is now added to the list with a Reader Address of 1. Click on the Close button to close the Rea de rs Admini st rati on win do w. 2.5 Preparing the DataSeal/DataTag DataSeals provided by Hi-G-Tek leave the factory in a special power saving mode called "Deep Sleep Mode". Before you can communicate normally with a DataSeal, you must send it a special command called "Hard Wakeup" that returns the DataSeal into its normal mode of operation. You will then have to close the Sealing Wire (as will be
Chapter 2 Quick Start Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 25 - explained below), and send another command called "Set" that prepares the DataSeal for normal operation. This section describes how to prepare a single DataSeal. If you have more than one DataSeal, repeat all the instructions in this section for each Dat aSeal you have. In order to send the Hard Wakeup command to the DataSeal or DataSeals do the following: Click on the button on the tool bar to open the window shown in Figure 2-3. Figure 2-3 - All Commands Window.
Chapter 2 Quick Start - 26 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy From the Command Code drop down list , select Hard Wakeu p. Copy the Seal ID of the DataSeal you want to wake up into the Seals/Tags ID t ext box. The Seal ID is print ed on t he st icker on the bottom of t he DataSeal. Click the Command Execution button. The mouse cursor will change to an hourglass icon for about 11.5 seconds and then return to a normal pointer cursor. If the DataSeal received the message, The Re s ult box will show the message "Command OK" in green letters. If not, verify that you typed the Seal ID correctly in the Seals/Tags ID box, and that the DataSeal is nearby, and try again. If you still don't get the green "Command OK" message, or you see a different red message in the Re sul t box, refer to chapter 9 for troubleshooting. If you're using a Dat aSeal (as opposed t o a Dat aTag), you now have t o close the Sealing Wire by inserting its 2 ends to the 2 sockets in the DataSeal. Push the ends inside the sockets as far as you can. (You should hear a 'Click' when the wire end is fully inserted). If you're using a DataTag, you should place the Sensor Plate in its appropriate place at the bott om of the Dat aTag. From t he Command Code drop down list , select Set and then click the Command Execution button. After about 4 seconds, a green "Command OK" message should appear in the Resul t box. Congratulations! Now your DataSeal is prepared for normal operation!
Chapter 2 Quick Start Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 27 - 2.6 Executing a Verify comm and As a matt er of fact , if everyt hing worked fine up to this point , you can be sure t hat your Demo System is working. Nevertheless, you probably want to know how to perform some basic operations. The most commonly used command is the Verify command. The main purpose of this command is to detect which DataSeals are currently around, and their status (opened/closed, tampered/not tampered). In order to execute a Verify command, open the Ve ri fy & Se t window, by clicking on the button on the tool bar. The window shown in Figure 2-4 will be displayed.
Chapter 2 Quick Start - 28 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy F igure 2-4 - The Verify & Set W indow. Note that there are 2 buttons labeled "Single Interrogation": the upper one resides in a rectangle labeled "Broadcast Verify", and the lower one in a rect angle labeled "Address Verify and Set ". In t his guide, we'll only use t he upper one (Broadcast Verify). Click this button now. After about 5 seconds, one or more lines will be added to the list, according to the number of DataSeals that were detected. Figure 2-5 shows an example of a list with 5 detected DataSeals.
Chapter 2 Quick Start Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 29 - Figure 2-5 - 5 DataSeals Detected. Clicking the Single Interrogation button again will add another one or more lines to the list. T o clear the list, click on the Rese t butto n at t h e bottom of the window. A complete explanation about the results you see is out of the scope of this Quick-Start chapter. Nevertheless, there are 2 flags in the DataSeal's Short Status that are worth a brief explanation here. 2.7 A Brief Tutorial Through the States of the DataSeal The DataSeal has many flags that determine its state, as well as Parameters, Event Records and User Data. Even though most of these features are out of the scope of this chapter, 2 of the flags represent the most fundamental concepts of the DataSeal. These flags are the Tampered flag (shown in Figure 2-5 as "S/T "), and the Opened flag (shown in Figure 2-5 as "O/C"). Note that in the Evaluation Software, flags that are set appear in red, while unset flags appear in black. If you have followed t his guide st ep by st ep up to t his point, you should have both flags off (black). If you cleared the list, click Single Interrogation (the upper one) again to see the flags.
Chapter 2 Quick Start - 30 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy The Opened flag is set (on) whenever the Sealing Wire is open, and unset (off) whenever it is closed. That explains why the O/C flag appears black. Now, open the Sealing Wire by pulling one of its ends out of the socket. Click the Single Interrogation button again to see that the O/C flag has turned red (on). You may have noticed that also the S/T flag has become red. This indicates that the DataSeal was Tampered. If you now close the Sealing Wire, this flag will remain on, even though the Opened flag will turn off again. Try it now: close the wire, and click the Single inte rrogation once more. You should see the O/C flag black again, but the S/T remains red. No matter how many times you would open and close the wire now, the Tampered flag remains set, to indicate that it was opened at least once. You can try it if you want. You may be wondering by now, whet her this t utorial led you to a st at e where the DataSeal is irreversibly tampered, meaning that the DataSeal is no longer usable! Well, you can relax because the Hi-G-Tek DataSeal is a reusable seal, meaning that you can clear th at Tampered flag. The Tampered flag can be cleared only when the Sealing Wire is closed, and it is done by sending a Set command to the DataSeal. That’s right, that's the same command you sent after the Hard Wakeup in the "Preparing the Seal/T ag" section. You can send this command from the Ve ri fy & Se t windows too. After performing a Single Interrogation, click on the line in the list that shows the Seal ID of the DataSeal you want to Set. Notice that the Seal ID now appears in the Seal ID box at the top part of the window. You may also type the Seal ID there manually if you prefer. Make sure that the Sealing Wire is closed, and then click on the Set button (inside the Addresse d Ve rify and Se t frame).
Chapter 2 Quick Start Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 31 - After about 5 seconds, you should see a green "Set OK" message in the Result box (in the upper left side of the window).

Chapter 5 DataReader Installation and Operating Instructions Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 57 - Example: 10 DataReaders connected in a daisy chain require 10x1.7=17W of power supply. Note that if the power supply is installed in a high temperature area (usually above 40° C), there is a derate in power supply wattage. (Refer to your power supply manual). For safety reasons, power supply current should be limited to 3A. Current limitation should be done internally in the power supply, or externally with a 3A fuse. Both in t he Out door and Indoor syst ems, t he power supply should be installed indoor. When power supply cable ends are connected directly to system cable, a proper isolat ion should be made. Using heat shrink t ube is recommended. 5.5.2 Indoor Installation When the DataReader is installed indoor, the power supply used should be UL1950 approved.

Chapter 5 DataReader Installation and Operating Instructions - 58 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy 5.6 Cable Selection The cable is used for power supply to DataReaders in a chain and for RS-485 serial communication. For most applications, 3 or 4 pairs of 24AWG shielded cable is adequate. The serial communication requires shielded twisted pair cable, the power supply requires low ohmic resistance of the conductors. Cable connection:  1 pair for RXA and RXB signals.  1 pair for TXA and TXB signals.  SIGNAL GND may be connected to shield or to a pair of wires (shield connect ion is recommended, t hough it depends on t he noise level of t he specific environment). For the power supply: two main issues should be considered: max current carrying capacity and wire resistance. Max current capacity: For 24AWG cable, the jacket is heated at 1°C at 0.1A current, max temperature is 80°C. So, this cable can carry a max of 2A at 60°C. ( (80°-60°)*0.1 ). This calculation should be done for the application specific requirements. Wire resistance: The voltage drop across the cable may cause insufficient voltage to the last DataReaders in the chain. Calculation of voltage drop for the certain setup should be done, in order to avoid this. In most cases, the solution for such problems can be connecting a pair of wires for the supply (2 for supply and 2 for return), using thicker cable, or
Chapter 5 DataReader Installation and Operating Instructions Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 59 - using higher temperature rated cable. Environmental considerations: In an outdoor installation, the cable should withstand all outdoor conditions, including wat er proof, t emperature, ruggedness et c. Example: A setup of 10 DataReaders with 20 meter 24AWG cable between DataReaders and 24v supply to the first DataReader. The ohmic resistance between DataReaders is 3.4 Ohms (20 meter of supply and 20 met ers of ret urn). Calculat ing the volt age drop across t he lines gives 5v only, left to the last DataReader in the chain. T his is below DataReader specification of DataReader minimum supply voltage. If two conductors are used for supply and ret urn, t he ohmic resist ance would be 3.4/2=1.7 ohm. The voltage to the last DataReader in the chain would then be 17v, well above the minimum voltage required. If you experience difficulty calculating the voltage drop across the supply line, cont act your dist ribut or for assist ance. 5.7 Installation Notes The DataReader is distributed to a commercial/industrial use only, and should only be sold to the professional customers. When installed outdoors, the unit shall be installed in accordance with the NEC or CEC. Installation must be performed according to this user manual, and by a professional personnel only. It is the responsibility of the installer to ensure that when using the outdoor antenna kits in the United States (or where FCC rules apply), only those antennas certified with the product are used. The use of any antenna other

Chapter 6 System Overview - 64 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy 6 System Overview 6.1 System description The Hi-G-Tek system consists of the following components: 1. DataSeal The DataSeal is a sophisticated device, which includes 2 transmitter/receiver units (one for high frequency/long range and another one for low frequency/short range communications), real-time clock, processor, memory and sensing circuitry for sealing verification. The Sealing Wire prevents any attempt of opening, bypassing, or tampering with the DataSeal without alerting the system and recording the event. Data may also be written into and read from the DataSeal to store and retrieve general information. The DataSeal can communicate both in low frequency with short range devices, such as the DataTerminal and MicroDataReader, and in high frequency for long ranges with the DataReader, together allowing a broad range of applications. 2. DataTag The DataTag is a variant of the DataSeal device. Instead of the Sealing Wire it has a removal sensing mechanism. T his makes it more suitable for cases where you want to tag goods, but you don't have to seal them. Other than that, it is identical to the DataSeal device. 3. MagneticDataSeal The MagneticDataSeal is a variant of the DataSeal device. Instead of the Sealing Wire it has a Magnet element. This makes it more suitable for cases
Chapter 6 System Overview Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 65 - where you want to sense if the door is open but you can’t seal it. Other than that, it is identical to the DataSeal device. 4. DataReader The DataReader uses in high frequency (long range) RF communication to communicate with the DataSeals mainly for reading their IDs and their Statuses. The DataReader can also be used for reading and writing information to and from the DataSeal and retrieving logged events from the DataSeal. Each DataReader can communicate with numerous DataSeals simultaneously and verify their presence and status. The DataReaders can also be chained together to allow a longer and wider range of coverage. DataReaders must be connected to a controlling computer that control them. 5. DataTe rminal (previously known as Hand Held Terminal or HHT) This is a mobile handheld device which includes a keypad, a small LCD screen, a low frequency receiver/transmitter, and an RS-232 interface. The main things that you can do with the DataTerminal are: Reading a DataSeal's ID and Status; Reset the DataSeal for a new use ("Set" command); reading and writing data to and from the DataSeal – for example: manifest number, truck number, driver name etc.; reading the events that were logged in the DataSeal; T ransferring this information to and from a PC. 6. DataPort (Previously known as Low Frequency Terminal, or LFT) The DataPort is a simple low frequency modem. It includes a low frequency transmitter/receiver and an RS-232 interface that connects to a PC. In other words, it enables a PC to communicate almost directly with a DataSeal. In general, the DataPort enables the PC to perform the same
Chapter 6 System Overview - 66 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy operations as the DataTerminal, given that an appropriate software exists in the PC. 7. Mi cro Da ta Re a de r The MicroDataReader is a key ring size mobile device that includes a lo w frequency transmitter/receiver, 1 or 2 buttons and a LED indicator. Using the MicroDataReader you can perform the following functions: 1. Verify – The LED will turn green if the DataSeal's Status is OK, or to red if it's Tampered. 2. Set (Optional) – prepares the DataSeal for a new use. The type of t he Se t c om m an d ( no rm al, So ft Set o r Susp e n de d Set ) is m o de l specific. Hi-G-Tek can provide MicroDataReaders with different commands if required. 6.2 DataSeal and DataReader Modes of Operation 6.2.1 DataSeal Modes of Operation Generally speaking, a DataSeal can be used in any of the following ways: 1. O peration Mode (Normal Mode ) This is t he normal and most basic mode of operat ion. In this mode, t he DataSeal is on standby most of the time. Once every predetermined period, called Tw , the DataSeal samples the HF (high frequency) channel searching for a transmission from a DataReader. If it detects such transmission, it listens and answers as needed. The default value of T w is 3 seconds, which is the most appropriate for most applications. In the Operation Mode, the DataSeal also listens constantly to the low frequency channel and responds as needed. During the Operation Mode the DataSeal
Chapter 6 System Overview Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 67 - logs events (like opened, closed, tampered, etc.) and stores them internally in t h e E v ent s Mem o ry . 2. Dee p Sle e p Mo de This mode should be used when the DataSeal is not in use in order to conserve energy. DataSeals always leave the factory in this mode. It is possible to ent er a Dat aSeal t o t his mode also by using high frequency or low frequency command. To exit this mode, interrogate the DataSeal using low frequency (for example, using a DataTerminal), or send a Hard Wakeup command in high frequency using a DataReader. Note: While in Deep Sleep mode, no Events are recorded. Events aren't recorded also after waking up the DataSeal, until a Set command is performed. In other words, after waking up a DataSeal, you must also perform a Set command in order for the DataSeal to start record events. 3. Alert Burst Mode This mode is similar to the Operation Mode. In addition, whenever the DataSeal is opened, it transmits an Alert Burst message in the high frequency channel. The DataReader and the application should both be configured to receive and handle the alert message. A DataSeal can be configured also to t ransmit Burst messages on other events. 4. Footprint Events Mode This mode is a way of using the DataSeal, rather than a configuration of the DataSeal. When the DataSeal receives a special variant of the Ve ri f y command in low frequency or in high frequency, it records a certain Event called "Read", that includes the DataReader's ID or the low frequency device's ID. To use this special command in the DataReader, the DataReader has to be configured accordingly. This mode is useful to determine the DataSeal's track if there are several DataReaders, or check
Chapter 6 System Overview - 68 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy points with DataTerminals along the way. In this scenario, you can know the DataSeal's track by reading its Events, without having to have these DataReaders connected to any central system. 6.2.2 DataReader Modes of Operation There are several aspects that determine the DataReader's mode of operation. T hese aspects are determined by the Mode parameter, which is a bit orient ed parameter. 5. Carrier Sense Collision Prevention Just like you can't understand what two people are saying when the speak simultaneously, that way a DataSeal can't understand two DataReaders that transmit simultaneously. When two (or more) close DataReaders aren't controlled by the same controlling computer (or by controlling computers that are synchronized among them), there's a chance that they will try to transmit simultaneously. In order to prevent that, the DataReaders can be configured to sense for a carrier (transmission of another DataReader or DataSeal) before they start transmitting. When a DataReader is configured for Carrier Sense, each time before it transmits something it listens to the frequency, and only if it's clear (no one else is transmitting), it start transmitting it s own message. 6. Burst Re cei vin g Mode When DataSeals are operating in Alert Burst mode, the DataReader’s receiver must be ON at all times in order to receive the Burst messages. The controlling computer has to query the DataReader periodically to receive the Burst messages that the DataReader received.
Chapter 6 System Overview Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 69 - 6.3 Most Common Commands and Seal Status 6.3.1 Most Commonly Used Comm ands There are a number of key commands that are used in most applications, as they enable the basic operation of the system. These commands are: 7. Verify The Ve ri fy command is used to detect DataSeals which are located within the DataReaders Receiving Zone and also verify their state. The DataSeals which respond may be in one of two states. The DataSeals may be in either the normal state, meaning the have not been tampered with, or in the tampered state, meaning they have been tampered with. Additional information can also be queried from the DataSeal. This is the most useful and commonly used command in the system. 8. Tampered The Tampered command is used to communicate with tampered DataSeals. The command operates the same as the Ve ri fy command only DataSeals which are in the Tampered state respond. T he aim of the command is to provide high priority to tampered DataSeals in a crowded DataSeals environment. 9. Set The Set command is used to set a DataSeal for a new use. The Sealing Wire must be connected and closed in order for a DataSeal to be set. The Se t command deletes all Events stored in the Events Memory and is the first new Event recorded in the DataSeal. The DataReader can send the Se t command to up to 8 DataSeals simultaneously. 10. Suspended Set
Chapter 6 System Overview - 70 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy Similar to the Set comman d, Suspended Set is used to set a DataSeal for new use. Unlike the Set command, when performing a Suspended Set command, the Sealing Wire Must be opened (or completely disconnected from the DataSeal). T he DataSeal will become armed (Set) once the Sealing Wire has been connected to the DataSeal and closed. 11. Approve Open The Approve Open command allows a Sealing Wire to be opened after the DataSeal has been set in a way that the application can determine that the DataSeal was opened with an approval. When the Sealing Wire will be opened after receiving this command, the application will be a ble to det ermine that t he opening is approved by examining the Approved Open flag in the DataSeal's Status. 6.3.2 DataSeal's Status The DataSeal's Status consists of 4 bytes. A DataReader may be used to request the DataSeal's Status. The DataSeal's Status is used to indicate the DataSeal's current state and is a bitwise value. Each bit in the Status represents a specific status flag. The DataSeal's Status is divided into the Short Status and Long S tatus parameters as explained below: The DataSeal's Short Status parameter consists of 1 byte (8 bits) which is a subset of the Long Status parameter. The Short Status contains the most important flags. These flags are: 1. Tampered – The Tampered flag gets set if the Sealing Wire was opened or tampered with. It remains set even if the Sealing Wire is closed again. It can only be unset by performing on of the Se t commands. 2. Low Battery Warning – Battery is low, replace the DataSeal. 3. Opened – Indicates that the Sealing Wire is open.
Chapter 6 System Overview Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 71 - 4. Suspende d Se t – A Suspende d Set command was performed, and the Sealing Wire wasn't closed yet. 5. Se aling Wi re Ch ange d – Indicates that the Sealing Wire's electronic characteristics have changed since the DataSeal was Set. 6. Deep Sleep – Indicates that the DataSeal is in Deep Sleep mode. 7. General Error – Indicates an error with the DataSeal that is not represented in the DataSeal's Short Status. 8. Approve d O pen – If the DataSeal Opened flag is on, the Approved Open flag means that the opening is approved. If the DataSeal's Opened flag is off, it means that the next open will be approved, if performed during a certain period. The DataSeal's Long Status contains the Short Status flags as well as 3 additional bytes that together represents the complete DataSeal's status. For a det ailed descript ion of the Long Status, see chapter 8. 6.4 System Planning When planning an application, attention should be paid to both system operat ion and topology. Applicat ion requirement s and elect romagnet ic environment characteristics should also be taken into account. 2 basic types of applications are possible: Fixed DataReader applications and Mobile DataReader applications. A complex application that combines DataReaders in both configurations is also possible. The Fixed DataReader applications are applications where the DataReaders are mounted at a fixed site. The Mobile applications are situations where the DataReaders are mounted on vehicles for monitoring DataSeals in transit. Mobile applications are normally implemented using the TrackingDataReader, but may also be implemented using a DataReader
Chapter 6 System Overview - 72 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy connected to any mobile controller (E.g. laptop, palmtop, etc), that has a serial communications port. 6.4.1 Electrom agnetic Environment Radio Frequency Communicat ion is t he basic t echnology used by t he system. While this is a very robust method for communicating with remote devices, several issues should be considered when planning a site.  Metal walls should not be used to shield the remote devices.  Communication distance between remote devices may vary due to atmospheric conditions and other electromagnetic interferences.  Communication distance may also vary according to one or more of the following: • Line of sight between devices – existence and clearance. • Proximity to metal objects. • Indoor or Outdoor environment. • Antenna orient at ion bet ween the devices. It is recommended to map the site with actual devices for proper coverage. When planning the site layout, safe margins should be taken into account to ensure proper operation at all times. Possible environmental changes should also be considered. 6.4.2 System Layout Two aspects should be considered when dealing with system layout: 1. Radio Frequency Communicat ion Layout . 2. Line Communication RS-485 or RS-232 Layout.
Chapter 6 System Overview Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 73 - 6.4.2.1 Radio Frequency Communication Layout. When only one DataReader is in use, the previously mentioned environmental considerations are all that need be taken into account. When more than one DataReader is in use, it should be understood that in the same area only one DataReader can communicate with the DataSeals at the same time. Interference will be caused by more than one DataReader Trying to communicate with the DataSeals in the same period of time. Th e DataReaders should be synchronized using the application software or using the Carrie r Sense mode. Several DataReaders may operate simult aneously provided t hat it has previously been confirmed t hat they will not interfere with each other. 6.4.2.1.1 Cellular Layout Cellular topology should be used to ensure efficient coverage of a large area. The following diagram illustrates the concept:
Chapter 6 System Overview - 74 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy DataReaders must be properly placed to ensure there are no dead zones within the defined area. Overlaps should be as shown in the above drawing. DataReader's Receiving Zone is the term used to describe the area of reliable communication covered by a DataReader. The DataReader's Receiving Zone is also called a Cell. As the drawing illustrates, it is extremely important that the application software controls and synchronizes the DataReader’s operation in order to avoid RF collisions. In other words, the application software has to make sure that no two DataReaders with overlapping Receiving Zones transmit at the same time. 6.4.2.2 Line Communication RS-485 Layout The connection of many DataReaders to a controlling computer is done via the RS-485 protocol. Up to 32 DataReaders may be connected to one serial Reader Zo ne
Chapter 6 System Overview Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 75 - communications port, depending on the type of RS-485 to RS-232 converter used. T wo topologies can be used:  A long daisy chain connection, where all the DataReaders are connected in one long line.  A star-type connection, where the DataReaders are split into groups and each group is connected directly to the converter. It is recommended that the second alternative be used wherever possible. A star-type connection provides better tolerance to connection failures. This alternative is also preferable from the power supply point of view, as only one power supply for the DataReaders is necessary. The power supply should be located near the converter. When the line is divided into segments, the voltage drop along the segments is smaller. 6.5 Systems Segregation When Hi-G-T ek has designed the system, several security and operational considerations have been taken into account:  Similar equipment belonging to one company should not be able to mess with another company's system either intentionally or unintentionally.  Limit unauthorized access between different departments of the same company. Equipment belonging t o one depart ment of a company should not be able to interfere with equipment of another department, either intentionally or unintentionally.  Service Providers should be able to communicate with their customer's equipment in order to supply common services to several companies. This should be done in an authorized an limited manner.
Chapter 6 System Overview - 76 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy  Dat aSeals may have to be divided int o groups that are not related t o companies or depart ment s. 6.5.1 Com panies Segregation by OrgID OrgID is a unique value assigned to each company by Hi-G-Tek or by one of its authorized dealers. Every device supplied to that company is pre-programmed with the same OrgID at product ion, and t he cust omer can't change it ever again. In every communication between two devices, the caller (e.g. DataReader) sends its own OrgID value. When the consignee (e.g. DataSeal) receives the message, it first compares the OrgID it received with its own OrgID, and only if they match the consignee performs the command and sends its response. If a DataSeal receives a message a different OrgID than its own, it turns on the Ille gal O rgID flag in the Lon g Status, and ignores the message. There's one exception in which a DataSeal can respond to a message with a different OrgID in order to allow collaborat ion with service providers. This is described in more det ails in sect ion 6.5.3. 6.5.2 Department Isolation Department is a unique value assigned by a company to a group of devices belonging t o the same depart ment . It is possible to isolat e equipment bet ween depart ment s by using t he Department parameter in the various devices. The default value of Department is zero in all devices. When set to that default sett ing, all t he devices can communicat e wit h one anot her without any limitations. If a DataReader's Department value is not zero, it can communicate only with DataSeals that has the same Department value.
Chapter 6 System Overview Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 77 - If a DataReader's Department value is not zero, it can communicate with all of the DataSeals in the same organization, even if their Department value is non-zero. Such a DataReader is considered "Supervisor". The Department parameter both in DataReaders and in DataSeals can be changed by the user at any time. 6.5.3 Services to Several Companies by a Service Provider The DataSeal has a boolean parameter named Gl obal, which is designed to allow a Service Provider to service several customers. If a DataSeal’s Global parameter is on, then that DataSeal will respond to any Ve ri f y command from any DataReader, regardless of OrgID. T he Ve rif y response will be a limited one, containing only a certain few of the DataSeal parameters. See the description of the Global paramet er in chapt er 8 for a list of the parameters that can be included in the Ve rify response in this case. Note: The Global paramet er is programmed during product ion, and it mu st be de fi ne d an d re ques te d i n a dvan ce . 6.5.4 Subgroups of DataSeals When a DataReader sends a Verify command In order to detect the DataSeals in its area, it can receive only a limited number of responses at a time. If there are many DataSeals in the DataReader's Receiving Zone there could be too many DataSeals trying to respond at the same time, and that would cause that none of them will be properly received by the DataReaders. In order to avoid that, the DataSeals can be divided into small groups and each group be assigned a unique value called ADI. When the DataReader will execute a Ve rif y command, it would be able to specify a specific group, and only DataSeals that belong to that group will respond. If the DataReader would iterate through the groups, it can receive all the DataSeal in a relatively short time.
Chapter 6 System Overview - 78 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy For that purpose, the DataSeal and DataReader devices have an ADI parameter. The ADI parameter works very similar to the De pa rtmen t parameter, with 2 differences: ADI is 4 bytes while Department is 1 only byte, and the controlling computer can explicitly specify a different ADI for each RF command it requests the DataReader to transmit. The ADI parameter can be used also to create groups by usage in other scenarios. 6.5.5 OrgID, Department, Global and ADI Impact on DataSeal’s Response The following statements summarizes when and what a DataSeal responds: 1. If the DataReader's Department parameter is zero, the De pa r tme n t is always considered to match. 2. If the DataReader sends a zero ADI, the ADI is always considered to match. 3. OrgID doesn't match and Gl obal is on: DataSeal will respond with limited Ve rif y command only. 4. OrgID doesn't match and Gl obal is off: DataSeal will not respond. Table 6-1 : OrgID and Global OrgID Global Effect: Unmatched ON DataSeal will respond with limited Verify command only Unmatched OFF DataSeal will not respond
Chapter 6 System Overview Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 79 - 5. OrgID matches, De pa rtme n t matches, and ADI matches: DataSeal will respond without limitations. 6. OrgID matches, and ADI doesn't match: DataSeal will not respond. Table 6-2 : OrgID, Department, and ADI OrgID Department ADI Effe ct: Match Match Match DataSeal will Respond without any limitations. Match Match/ Unmatched Unmatched DataSeal will not respond Match Unmatched Matched/ Unmatched DataSeal will not respond Unmatched Match/ Unmatched Match/ Unmatched DataSeal will not respond 6.6 DataSeal's Memory The DataSeal's Memory is divided int o 2 sect ions: Event s Memory and User Data. 6.6.1 Events Mem ory This memory stores the Events detected by the DataSeal during normal operation. This memory can contain up to 55 Event records. The memory has a FIFO type structure with 2 segments: The first segment can store 45 Events and is a simple FIFO buffer. The second segment can store 10 Events and is a cyclic buffer with the last Events detected.
Chapter 6 System Overview - 80 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy When this cyclic buffer is overrun, the Scroll flag in the Long Status is set. The Se t Event is always the first Event record in the Events Memory. Se t Event First segment : 45 Events Second segment : 10 Events Some Events are caused by an external intervention (like Opened and Closed), while others are caused by internal procedures. The most common Events are the Se t, Tampered, Opened an d Close d Events. See chapter 8 for a complete list and descriptions of each Event type. 6.6.2 User Data User Data is the memory segment where free data can be written and read. For example, the electronic manifest can be stored in this memory. The User Data can be read and written using the Rea d Da ta and Write Data RF commands accordingly. The User Data can also be read by the Verify an d t h e Read Multi Access Data RF commands. The size of the User Data memory segment is 2KB.
Chapter 6 System Overview Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 81 - Even though all the User Data is simply a flat memory segment, the lowest 53 bytes are of special meaning for the DataTerminal. If you're using or considering to use a DataTerminal in your system someday in the future, you should use these 53 bytes in a way that is compatible with the DataTerminal. The DataTerminal uses the first 53 bytes as follows: 6.6.2.1 The User Data portion used by the DataTerminal The DataT erminal is capable of viewing and editing 48 bytes (addressed 5 – 52) of the User Data as a structure of ASCII fields. This structure has to be defined first by t he user, using a special P C soft ware provided wit h t he DataTerminal, and then uploaded to the DataTerminal. The structure definition includes the labels and sizes of the fields and is assigned an identifier (called UDT), and a version number. When the user writes User Data using the DataTerminal, the DataTerminal always stores this identifier and version number in address 0, and the date and time when the data was written, in addresses 1-4.

Address Byte Content 0 UDT Version 1 2 3 4 Time & Date 5 . . . 52 Data 6.7 System Comm ands The following list describes t he commands t hat can be sent t o one or more DataSeals by the DataReader. For more information about each command see chapter 8 and the DataSealLib COM DLL help file. 1. Verify – Uses to detect DataSeals located inside a DataReader's Receiving Zone. 2. Tampered – Uses to detect DataSeals located inside a DataReader's receiving zone that are in the Tampered state.
Chapter 6 System Overview Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 83 - 3. Set – Uses to prepare DataSeals for a new use. Sealing Wire must be attached and closed prior to the Set command. This command can be sent up to 8 DataSeals simult aneously. 4. Suspende d Set – Similar to the Se t command except that the Sealing Wire must be open prior to performing the command and the DataSeal gets set once the Sealing Wire is closed. This command can be sent to up to 8 Dat aSeals simult aneously. 5. Soft Set – Similar to the Se t command, the Soft Set command is used to prepare DataSeals for a new use. Unlike the Se t command, the Soft Se t command does not delete the previously recorded Events in the Event s Memory. This command can be sent t o up t o 8 Dat aSeals simultaneously. 6. Deep Slee p – Puts the DataSeal into Deep Sleep mode. T his command can be sent to up to 8 DataSeals simultaneously. 7. Hard Wakeup – Brings DataSeals which are in Deep Sleep mode back t o normal operat ing mode. This command can be sent to up to 8 DataSeals simultaneously. 8. Start Alert Burst Mode – Puts DataSeals into Alert Burst mode. This command can be sent to up to 8 DataSeals simultaneously, or to all the receiving DataSeals. 9. Stop Alert Burst Mode – Brings DataSeals which are in Alert Burst mode back to normal operat ing mode. This command can be sent to up to 8 DataSeals simultaneously, or to all the receiving DataSeals. 10. Acknowledge Alert Burst – Acknowledges the reception of Alert Burst messages from DataSeals. T he Ackno wle dge Ale rt Bu rs t command tells the DataSeal that its message has been received. After receiving an Ackno wle dge Ale r t Bu rs t command, the DataSeal stops transmitting its Burst message until a new Tampered event is detected. This command can be sent to up to 8 DataSeals simultaneously. 11. Read Data – Retrieves data from a DataSeals’ User Data area.
Chapter 6 System Overview - 84 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy 12. Write Data – Writes data into a DataSeal's User Data area. 13. Reset Data – Erases all the data in a DataSeals’ User Data area. 14. Se t/Reset Status – Sets or resets specific flags of the DataSeal’s Lon g Status. 15. Write Parameters – Writes new values to one or more DataSeal parameters. 16. Read Parameters – Reads the values of one or more DataSeal parameters. 17. Addressed Verify – The Addresse d Verify command is the same as the Verify command except that it is applicable to only one DataSeal. This command is most commonly used to verify that a specific DataSeal is located within a DataReader’s Receiving Zone. 18. Multi Addressed Verify – T he Multi Addresse d Ve rify command is the same as the Addressed Verify command, but is applicable t o up t o 7 DataSeals simultaneously. 19. Read Eve nts – Reads part of or all Events stored in the DataSeal’s Events Memory. 20. Approve Open – Permits to open a DataSeal after it has been Se t. If opened, both the DataSeal's Approve d O pen and the Tampered flags will be set. This command is intended for recognizing permitted DataSeal openings. 21. Start Forced Burst – Forces the DataSeal to send a special Burst message called Forced Burst. It is most useful when this command is executed in Low Frequency, and by that causing the DataSeal to send information to the DataReader. When used in high frequency, it may be executed in one DataReader, while a different DataReader (in another place for example), should receive the Fo rce d Bu rs t message. 22. Temporarily Disable HF – Disables the HF channel in a DataSeal for a specified period. This is useful to conserve battery when the area may
Chapter 6 System Overview Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 85 - be dense with HF communications that don't apply to that DataSeal, or to prevent the DataSeal from responding to a Ve ri f y command for a certain period, in order to allow other DataSeals to be received.

Seal Status indicators: When a DataSeal responds to an Addressed Verify command, these indicators reflect the DataSeal's Long Status as reported by the DataSeal. Flags that are set appear in red, while unset flags remain black. When a DataSeal responds to a Se t command, only the Short Status is returned and is indicated by the leftmost column. The rest 3 columns are dimmed. A complete list of the DataSeal's Long Status flags and their meanings appear in chapter 8. 7. Broadcast Verify responses list: After a Broadcast Verify interrogation, the responses of the DataSeals are added to this list. 8. Cyclical interrogations control frame: T his frame contains some controls that you can use to affect the way that a cyclical interrogation (Broadcast or Addressed) is executed. 7.4.1 Executing Broadcast Verify Command The B ro a dcas t Ve ri fy command (sometimes referred to simply as Ve rify) is a command that collects information from all the DataSeals that receive the command (given that their OrgID, Department and ADI match). This command is the most powerful command, and has many parameters that enable to fine tune its behavior. A complete description of all the parameters is given in chapter 8. Normally, the default values of the parameters are adequate, but you may change them to best suit your needs. If you want to execute the B ro a dcas t Ve ri fy command only once, click on the Single Inte rrogation butt on (shown in Figure 7-0). You can also execute the Broadcast Ve ri fy command continuously (or cyclically) by
Chapter 7 Evaluation Softw are Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 95 - clicking the Cyclical Interrogation but ton. You can control some aspects of the cyclical interrogation from the cyclical interrogations control frame (item #8 in Figure 7-0) as described in section 7.4.4. The results (responses) of the Broadcast Ve rify command are displayed in the Broadcast Verify responses list (it em #7 in Figure 7-0). The results are always appended to this list. To clear the list click on the Rese t but ton on t he lower right side of the window. Each response in the Broadcast Verify responses list contains the following information:  Seal ID  Events: The number of Event records that exist in the DataSeal.  Seal Short Status: This column is divided into 7 sub columns, each represents a single flag in the DataSeal's Short Status. If the flag is set (on), the flag appears red, and if unset (off) the flag appears black. T he flags are: • S/T – Set/Tampered: if on, indicates that the DataSeal was tampered. • LBW – Low Batt ery W arning. • O/C – Open/Close: if on, indicates that the Sealing Wire is open. • SS – Suspended Set: if on, indicates that the DataSeal is in Suspended Set stat e. Figure 7-0
Chapter 7 Evaluation Softw are - 96 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy • WRC – Wire Resistance Changed: indicates that an attempt to short circuit the Sealing Wire was detected. • Sleep – If on, indicates that the DataSeal is in Deep-Sleep mode. • GE – General Error: if this flag is on, it indicates a problem that can be determined by other flags in the DataSeal's Long Status, t hat are not included in t he Short Status. • Session: This column displays the sequential number of the session (interrogation). This number is increased with each new Verify command. This paramet er is added by the Evaluat ion Soft ware, and is not part of the DataSeal's response. • Rdr (Reader): The Reader Address of the DataReader that executed t he command. T his paramet er is added by t he Evaluat ion Soft ware, and is not part of the DataSeal's response. You can sort the list using any of the following columns by clicking on the title of that column: Seal ID, Events, Session and Reader. The content of the Broadcast Verify responses list can be saved to a tabbed-delimited text file (Seals.txt), by choosing Save to Seals.txt from the File menu. After saving the file, you'll be given the possibility to view the file (if a correct version of Microsoft Excel is installed, the file will be viewe d using Excel, otherwise it will be viewed using Notepad). 7.4.2 Executing Addressed Verify Comm and The Addresse d Verify command is similar to the B roa dca st Ve ri f y command except that it addresses only one specified DataSeal, instead of all the DataSeals that receive the command. In order to execute an Addresse d Ve rify command, you must first specify the Seal ID of the DataSeal you want to interrogate. You do it by typing the
Chapter 7 Evaluation Softw are Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 97 - Seal ID into the Seal ID box (Item #3b in Figure 7-0). Another option is to select the Seal ID from the Broadcast Verify responses list (It em #7 in Figure 7-0), if it previously responses to B roadcas t Verify. As in the B roadcas t Ve ri fy frame, here you also have the Single Interrogation and t h e Cy cli cal Inte rrogati on options: clicking the Single Interrogation button will execute the Addresse d Verify command only once, while clicking the Cyclical Interrogation button will execute the Addressed Ve rify command cyclically according to the options that are selected in the Cyclical Interrogations control frame (Item #8 in Figure 7-0) as described in section 7.4.4. The result (response) of the Addresse d Ve rify is displayed in the Addresse d Verify response indicat ors (It em #5 in Figure 7-0) and in t he Seal St at us indicat ors (It em #6 in Figure 7-0). The Addressed Ve ri fy response indicators contains the following fields:  Data & Time – The current date and time in UTC (GMT) as returned by the DataSeal. Figure 7-0 Figure 7-0
Chapter 7 Evaluation Softw are - 98 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy  # of Events – The number of Event records that are written in the DataSeal.  Seal Stamp – The value of the Seal Stamp parameter of the DataSeal. This parameter is a random number that is generated on each open and close.  Rdr Addr (Reader Address) – T he Reader Address of the DataReader t hat execut ed the command. This field is added by the Evaluat ion Software and is not part of the DataSeal's response.  Status – OK or Tampered. In addition to these indicators, the Seal Status indicators also indicates the DataSeal's Long Status. Flags that are set appear in red, while unset flags appear black. For a complete list of the flags in the DataSeal's Long Status, and their meanings see chapter 0 8. If the DataSeal didn't respond to the Addre ssed Ve ri fy co mm an d, t h e Result indicat ion box (It em #4 in Figure 7-0) displays a red message "Seal does not respond". 7.4.3 Executing Set Command The Set command is used to prepare a DataSeal for a new use. T he Se t command is addressed to a specific DataSeal (in fact, it can be addressed to up to 8 Dat aSeals simult aneously, but the Evaluat ion Soft ware does not support it through this window). In order to execute a Set command you must first specify the DataSeal you want to send the command to in the Seal ID box (It em #3b in Figure 7-0). You can do it also by selecting it from the Broadcast Verify responses list (It em #8 in Figure 7-0) if it ap p ears t h er e. The Sealing Wire must be close in order for the Set command to succeed. The result of the command is indicated using the Addressed Verify

In the No. of cycles box you can enter the number of cycles that will be executed. If you enter "-1", the Evaluation Software will execute interrogations until you click on the Stop Cycle butt on. Even if No. of cycles is not "-1", you can click on the Stop Cycle button to stop the interrogations. In the System Pause field you can specify the pause between one interrogation to the next in seconds. The Loop through all Readers check box is available if more than 1 DataReader is defined. If this check box is checked, the Evaluation Software will execute the first interrogation using the first DataReader in the list, the second interrogation using the second DataReader and so on. After the last DataReader was used, the first one is used again, and so on. For example, it there are 3 DataReaders, and No . o f cy cles is 8, t he order that the DataReaders will interrogate will be: 1,2,3,1,2,3,1,2. The Session # box indicates the sequential number of the interrogation. The Evaluation Software increases this value with each new interrogation. To reset this number, and to clear the Broadcast Verify responses list, click the Reset but ton. Figure 7-0

Micro elec tro nics & A sset Tra cking Techno logy 7.5 Executing Any Command using the All Commands Window The All Comm an ds window lets you execute any RF command and play with the "bits and bytes" of the RF protocol. Normally, when a software programmer writes an application, he doesn't have to play with the bits and bytes, because the DataSealLib software library (COM DLL) provides higher level interfaces, but acquaintance with the bits and bytes can be very helpful sometimes. Also, this is the only place in the Evaluation Software that you can execute all the RF commands. To access the All Comman ds window, choose the All Commands item from the Se als menu as shown in Figure 7-0. Alternatively, click on the All Comman ds icon or press Ctrl+A. Figure 7-0
Chapter 7 Evaluation Softw are Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 101 - 7.5.1 Executing an RF Comm and To execute an RF command do the following: 1. Select the command from the Command Code drop down list . T he code of the command will be displayed to the right of the drop down list, and the Command Data field will be filled by the default parameters for that command in hexadecimal format. For commands that does not have any parameters this field will be empty. 2. You may change the arguments in the Command Data line as desired. A detailed explanation of each command's structure is the following sections. 3. Select the DataReader that you want to use from the Reader drop down list. Figure 7-0
Chapter 7 Evaluation Softw are - 102 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy 4. If t he command is an addressed command or mult i-addressed command (also called BMM List), you have to enter the Seal ID of the DataSeal or DataSeals that you want to address in the Seals/Tags ID box. To enter more than one Seal ID, enter each Seal ID on its own line. 5. Click the Command Exe cuti on button. The results will be displayed in an hexadecimal format in the Re s pon se box, and for some commands the result will be displayed also as a table or as text. You can also execute a command cyclically by clicking the Cyclic Ex e c uti on button instead of the Command Exe cution but ton. T o stop the cyclical execution click the Stop butt on. Using t he System Pause field you can specify the pause in seconds between two interrogations in a cycle. The Re a de r Ses sion field displays the duration in milliseconds of one interrogation of the selected command. For some commands you can also change this value. However, note that specifying lower value than the default will usually cause an error. When the command completes, the Re sul t box indicates whether the command succeeded or failed. 7.6 Specific Comm and Structures Below is a description of the each one of the RF commands. For each command its structure (Command Data) is given and also the structure of t he response. Complet e descript ions of the command argument s are given in chapter 8.

T h e command parameters and response structure are identical to the Ve ri f y command. 7.6.3 Addressed Verify The Addressed Verify command is identical to the Verify command, except that it is addressed to a specific DataSeal. This command is an Addressed command, and therefore the Seal ID of the addressed Dat aSeal has t o be ent ered in the Seal s /Tags ID field before executing the command. The arguments of the command are identical to the arguments of the Ve ri f y command. Note however that there is no use in specifying Rr that is different than Nr in Addressed Verify, because there are no collisions. Nr and Rr can be greater than 1 in order to increase the probability of reception in case of RF interferences.
Chapter 7 Evaluation Softw are - 106 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy 7.6.4 Set The Se t command is used to prepare a DataSeal for a new use. If the Sealing Wire is open while the DataSeal receives the command, the command is not executed. If the Sealing Wire is closed, then all the Event records are deleted, the Tampered flag is cleared, and a new (first) Event record is written to indicate the Se t operation. This command is multi-addressed, and can be sent to up to 8 DataSeals in a single command. You must enter between 1 and 8 Seal IDs in the Seals/Tags ID box, one in each line, before executing the command. The Seal Status in the response indicates whether the command succeeded or failed: If the Status is OK (closed, not tampered) the command succeeded, and if it is tampered the command failed. An example of this can be seen in the Re s pon se box in Figure 7 -0 : the first row indicates an open Sealing Wire and Tampered state, (the Se t operation failed), while the second row indicates a closed Sealing Wire and OK state (the Set operation succeeded). Figure 7-0
Chapter 7 Evaluation Softw are Hi-G-Tek Ltd.

You must enter between 1 and 8 Seal IDs in the Seals/Tags ID box, one in each line, before executing the command. 7.6.6 Suspended Set This command is also similar to the Set command, but unlike the Se t command, the Sealing Wire can be open, and the operation completes only afterwards, when the Sealing Wire is closed. Between the command execution and the closing of the Sealing Wire, the Suspended Set ( SS) f la g in the Sh ort Status is set. Only when the Sealing Wire is closed, the Event records are deleted, the Tampered flag is cleared and a new Suspended Se t Event record is written. If the Sealing Wire was open at the time of the command execution, the DataSeal's will indicate the following flags in the Status: Tampered, Opened, and Suspende d Se t. If the Sealing Wire was closed at the time of the command execution, the DataSeal will indicate an OK status.

Chapter 8 System Parameters and Commands - 132 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy 8 System Parameters and Commands This chapter describes the details of the communications with the DataSeal and the DataReader. Even though Hi-G-Tek publishes the RS-232/485 protocol of the DataReader, and part of the RF protocol, this manual does not cover these details. Instead, it describes the commands and the parameters in a more conceptual way, with syntax and examples in Visual Basic as they can be used through the DataSealLib COM library. Note there's also an online help that is supplied with the library. This online help is more technical than the explanations in this chapter: while this chapter explains the concepts, the online help describes the COM interface in more details. 8.1 The High Frequency RF Protocol 8.1.1 The Basics In order to conserve power, the DataSeal is "asleep" most of the time. It only opens its High-Frequency receiver for a short time every predetermined period – usually 3 seconds. This fact has some implications on the RF protocol as explained below. The interval in which the DataSeal opens its receiver is determined by a configurable parameter called Tw (which its default value corresponds to about 3 seconds). Because the DataSeal listens to the RF only in this intervals, if a DataReader wants to communicate with that DataSeal, it must transmit a special signal called Reader Interrogation Header, that is at least in the duration of Tw , in order for the DataSeal to receive it. When the DataSeal receives this signal (in the short period that its receiver is open), it knows that a command should follow, and it waits for that command. After
Chapter 8 System Parameters and Commands Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 133 - receiving and performing the command and responding if necessary, it returns to the state of sleeping and opening the receiver every Tw .  The duration of the Reader Interrogation Header should be 135msec more than Tw . The DataReader has a configurable parameter called Th w that determines this period. Note that the DataSeal's Tw parameter should be configured with the same value for all the DataSeals, and the corresponding Th w parameter value should be configured appropriately in all the DataReaders in a given system. Figure 8-0 demonstrates the concept of the wakeup period and the Reader Interrogation Header. The upper line represents the time line of the DataSeal, and the bottom line represents the time line of the DataReader. It is clear to see from that figure why Th w (the length of the Reader Interrogation Header) should be just a bit more than the Wakeup Period (Tw ).

This way, when a DataSeal receives the Reader Interrogation Header, it doesn't have to keep its receiver open until the command, rather, it goes to sleep exactly until the command. Choosing the best Tw and Th w should take in account the following facts:  Small Tw and Th w will improve response times for RF command. Big Tw and Th w will cause lengthily interrogations.  Small Tw and Th w will shorten the battery lifetime of the DataSeals. Big Tw and Th w will lengthen it. 8.1.2 Addressing Types In general, there are 3 types of commands that are distinguished by the way they indicate which DataSeal or DataSeals will respond: 1. Addressed (AMM): These commands specify exactly one Seal ID. Only the DataSeal with that Seal ID responds. 2. Multi Addresse d (BMM List): These commands specify a list of Seal IDs. The DataSeals in the list respond in the same order as they appear in the list. This way there are no RF collisions between the responses of t he different DataSeals. Mult i Addressed commands wit hout argument s can contain up to 8 Seal IDs in the list. Currently, the only Multi Addressed command with arguments is the Multi Addresse d Verify, which can contain up to 7 Seal IDs. 3. Broadcast (BMM): These commands are aimed for all the DataSeals that receive the DataReader's transmission. There are actually 2 types of broadcast commands: commands without response and commands with response. The commands that do not wait for a response from the DataSeals are the simplest, in the way that after the DataReader has
Chapter 8 System Parameters and Commands Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 135 - transmitted the command, the commands is completed, and whatever DataSeals that received the command, performed it. The second type – commands with response – use the Slotted Aloha concept in order to overcome potential RF collisions between the responding DataSeals. The only commands of this type are the (broadcast) Ve ri f y and the Tampered commands. T he Slott ed Aloha concept is described in t he following paragraph. 8.1.3 The Slotted Aloha Concept Because the set of the receiving DataSeals is not known in advance, there's no deterministic way to synchronize their responses. In other words, RF collisions are unavoidable. However, by using retransmits, the probability of receiving all the responses can be very high. Here's the way it works: The command includes 2 arguments that are relevant to this matter: Nr an d Rr. Nr determines the total number of windows (time slots) in which the DataSeal can respond, and Rr determines how many times the DataSeal will transmit its response (or: how many time slots the DataSeal will actually use to send its response). It is clear that Nr should be much greater than Rr in order to allow many DataSeals to be received. Each DataSeal randomly chooses Rr time slots in which it will respond. The following table demonstrates the situation when Nr (number of windows) is 23, Rr (number of retransmits) is 4, and there are 3 DataSeals in the DataReader's Receiving Zone: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 1 x x x x 2 x x x 3 x x x
Chapter 8 System Parameters and Commands - 136 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy In this table, each row represents one DataSeal, and each column represents a windo w. An 'X' in a cell represents that the DataSeal sent its response in the specified window. Note that there are exactly 4 'X's in each row, corresponding to Rr. You can see that even though there were some collisions (in windows 4 and 16), all the 3 DataSeals have at least 1 transmission that does not collide with any other transmission. In order to achieve high probability to receive all the DataSeals, an estimation of the maximal number of DataSeals that would respond should be t aken in account before selecting t he appropriat e values for Nr and Rr. Fortunately, DataSealLib provides a function that calculates the appropriate values for Nr an d Rr according to the maximal number of expected DataSeals. This function is the RFParameters.DefaultsFor method. In fact, the newer DataSeals (versions 3.0 and above), use an improvement of the Slotted Aloha concept: Whenever the DataReader receives a specific DataSeal it sends an acknowledge to that DataSeal, causing it to stop retransmitting its response. This lowers the probability for further collisions and can shorten the total time of the interrogation by using lower Nr value, or allow more DataSeals to be received in the same time. T he RFParameters.DefaultsFor method takes this improvement into account too. 8.2 DataSeal Parameters The DataSeal can be configured very flexibly to fit almost any application requirements. For that purpose it has a set of predefined Parameters that can be read and/or written. The DataSeal also has some Parameters that are read-only, either because they are configured in the factory (like the Seal ID), or because they are status Parameters. All the Parameters can be read using the Rea d P a rame te rs RF command, and all the Parameters that are not read only can be written to the DataSeal using t he Write Parameters RF command. Some Parameters can also be
Chapter 8 System Parameters and Commands Hi-G-Tek Ltd.

In DataSealLib, all the DataSeal Parameters has corresponding properties of the Seal object. See the online help for information about how to use these properties. There's also an enumeration that contains constants for the parameter codes (HGTSealParameterCodeEnum).

This is always the same as Code + 80h.  Reade r ID – T he ID of the device that caused the Event (for example, in a Set operation). Note that this is not necessarily an ID of a DataReader – it could also be the ID of a DataT erminal, DataPort or any other kind of device that could cause the Event. Note: If DataSealLib recognizes the Reader ID as a DataReader that it knows it returns the Rea de r object instead of the Reader ID itself.  Se alStamp2 – 2 Additional bytes that contain data specific to the type of Event.

When the command completes, its Re sul t property contains the results. For further information about this argument and the RFCommandO bject class see the online documentation.  ADI – This is the ADI (group ID) that will be sent with the command. See chapter 6 for further information about ADI. The following sections contain a summary of the (HF) RF commands and their arguments. The R FC om m an dO bje c t an d ADI arguments are omitted from each command, because they are common to all and described above. Argument s that are relevant only t o Dat aSealLib and does not affect the RF communicat ions, are omitt ed t oo. See t he online documentat ion for help about these arguments.

Acknowledge Alert Burst, Acknowledge Close Burst, Acknowledge Forced Burst Me thod Se als.AckBurst Description Tells the DataSeals that send the specified type of Burst message that their message has been received, and that they can stop sending more retries of it. Remarks The method has an argument called AckBurstType that determines the specific type of command to perform. When a DataSeal receives this command it stops sending more retries of the same Burst message of the specified type, until a new Event of this kind occurs. 8.5 Burst Messages Burst messages are messages that a DataSeal transmits to the listening DataReaders. Unlike the RF commands, the Burst messages are sent from the DataSeal not as a response to a command, but asynchronous to the DataReader's transmissions, as a result of some kind of event. Be aware that Burst messages may interfere with normal RF commands transmissions because they are not synchronized with them. Proper system design should be made in order to prevent or overcome these cases. There are 4 events that can cause Burst messages: Sealing Wire is opened, Sealing Wire is closed, The DataSeal is being put in Deep Sleep (either through HF or LF), and an event that is initiated by a special RF command
Chapter 8 System Parameters and Commands Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 211 - called Start Forced Burst (either LF or HF). Further details about each type of Burst message are given below. Burst messages should be enabled in the DataSeal, by sending the Start Alert Burst Mode or Start Alert Burst Mode for All Seals co mm an d. I n addition, in order for a DataReader to receive Burst message, a special flag called Allow Burst in the DataReader has to be on. When a DataReader receives a Burst message, if it's All o w Bu rs t flag (Reader.AllowBurst property) is on and it is not currently executing another RF command, it stores t he message inside its memory. The application soft ware should check for Burst messages periodically in order to receive them, using the Reader.GetBurstMessages method. In addition, Close Burst messages have to be enabled in the DataSeal by setting the Close Burst Mode flag in the DataSeal's Long Status. Burst messages can be sent more than once (for each causing event) in order to maximize the probability that a DataReader will receive the message. T he exact number of retries is determined by the Maxim al Ale rt and Close Burst Retries an d Maxi mal Dee p Slee p Burst Retrie s DataSeal parameters, and the intervals between them is determined by the Alert and Close Burst Period and the Dee p Slee p Burst Period. For Forced Burst messages the number of retries an the interval is determined by the command arguments. When a DataReader receives a Burst message, it can send an acknowledge back to the DataSeal, so the DataSeal can stop sending more retries of the same message. This helps to reduce the DataSeal's battery usage and make the RF environment less "noisy". There are 2 options to acknowledge Burst messages: automatic and manual. The automatic acknowledge is sent by the receiving DataReader immediately when it receives the message. In order to use the automatic acknowledge, the Au tom a tic Ackn owle dge Bu rs t flag (Reader.AutoAckBurst property) in the DataReader should be on and also
Chapter 8 System Parameters and Commands - 212 - Hi-G-Tek Ltd. Micro elec tro nics & A sset Tra cking Techno logy the 2nd bit in the DataSeal's Fl ags parameter should be on. If the Au tom a ti c Acknowledge Random Delay flag (Reader.AckBurstRandomDelay property) in the DataReader is on too, the DataReader will randomly choose 1 of 4 windows in which it will send its acknowledge. The advantages of the automatic Burst acknowledge are:  The acknowledge is very short (about 50ms).  The application doesn't have to take care of it. The disadvantages of the automatic Burst acknowledge are:  The acknowledge does not ensure that the application received the message.  If the Au to ma ti c Ackn o wle dge Ran dom Dela y flag is off, if more than one DataReader receives the message, and both will try to send an acknowledge, the RF transmissions of these acknowledges will collide.  If Automatic Acknowledge Random Delay flag is on, for 2 DataReaders there's a chance of 25% for collision, for 3 DataReaders 35%, and for 4 DataReaders or more the probability rises to about 50% or more. The manual acknowledge is a normal RF command initiated by the application. Note that DataSealLib sends this command by default when the application gets the Burst messages from a DataReader (using the Reader.GetBurstMessages met hod), but you have t he opport unity t o cancel it, and/or send it when most appropriate to you. See the online documentation for more information. The advantages of the manual Burst acknowledge are:
Chapter 8 System Parameters and Commands Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 213 -  The application may send the acknowledge after it has written the message to a database. This ensures that no data will be lost even in case of application crash or DataReader's reset.  The application can send only one acknowledge to every burst message even if many DataReaders received it or more than one retry was received.  The application can choose the most appropriate timing for sending the acknowledge. The disadvantages of the manual Burst acknowledge are:  Because it is a normal RF command it takes the 3 seconds of the Reader Interrogation Header (Th w ) .  It is not automatic. Nevertheless, DataSealLib sends it automatically by default . Note that more than one DataReader may receive the same Burst message, and that each DataReader may receive more than one retry of the same burst message. It is the application's responsibility to correlate equal Burst messages. There are 2 formats of Burst messages: one is older, an always included only the Short Status of the DataSeal. T he new format can include any parameter and/or User Data. See the description of the Alert Burst Data Descriptor, Cl ose Bu rs t Da ta Des cri pt o r and the arguments of the Start Forced Burst RF command for informat ion about how t o define which parameters and User Data will be included in each type of message. In addition, the new format includes a sequential number for each event that caused a Burst message. This way you can easily correlate messages that are received by different DataReader, or 2 retries of the same message. T he Forced Burst messages also contain a special Use r C o de argument that the user can use to define the purpose of the Burst message. In DataSealLib, y o u receiv e t h e Burst m essages t hro ugh th e Re a de r.Bu rs t Ex ev ent , an d
Chapter 8 System Parameters and Commands - 214 - Hi-G-Tek Ltd.

This is like a "watchdog" for the RS-232/485 communication. You should set this value to the biggest gap you expect between 2 commands that are addressed to that DataReader. If you set this parameter to 0, and there is a problem with the RS-232/485 communications you will have to reset the DataReader manually.

Remarks DataSealLib also provides several Boolean or enumerated properties that reflect specific flags of this parameter: CarrierSense – Determines whether the DataReader will make sure that the RF is clear before starting transmitting a command. Use this flag when there are DataReaders that are not connected to the same controlling computer to avoid RF collisions. In synchronized systems this flag should be off to ensure that the timings are deterministic. AllowBurst – Determines whether the DataReader will listen for Burst messages while it is not executing another RF command. If this flag is on, you have to check for the Burst messages that the DataReader received using t he Reader.GetBurstMessages method. Powe rCali bration Mo de – Because temperature changes affect t ransmission power, it is required to perform a t emperat ure t est and power calibration process every once in a while. This property determines the terms in which the DataReader will perform those operations. See the online document at ion for further informat ion about the different opt ions.

Even though the default 3 seconds is mostly a reasonable response time, when you have to send many RF commands, it can accumulate to a lengthily time. The Command Chain feature allows to execute many RF commands in a row with a single Reader Interrogation Header (one Th w ). The bat tery consumpt ion of all the DataSeals that are in Normal Mode (not in Deep Sleep or HF Disabled), even those that are not addressed by any command in the Chain is exactly
Chapter 8 System Parameters and Commands Hi-G-Tek Ltd. Micro electro nics & Asset Tracking Technology - 231 - the same as it would if these commands were executes normally one after the other, but now that consumption is at a shorter period. However, in times that there are no transmissions, the battery consumption is normal (unlike the result of using a small Th w and Tw ). Commands can also be adde d t o the Command Chain on t he go, when you want to perform a command as a result of the response or responses that you received in a previous command. For example, suppose that you want to perform a Set command to all the DataSeals that their User Parameter 1 contains the string "READY". You can do it by initiating a Command Chain with only a broadcast Ve rif y command that asks for the User Parameter 1 parameter, and after receiving the results and examining the cont ent of the Use r Pa rame te r 1 parameter, you add the Set command with the list of Seal ID's of those DataSeals that their User Parameter 1 parameter contain the string "READY". Note that all the DataSeals that receive the Reader Interrogation Header of a Command Chain keep listening to all the commands, which consumes battery as if these commands were executed one after the other. For DataSeals that there are no command for them it means a waste of battery. There are few things that you can do to avoid it: 1. Make sure that the DataSeals that should not receive the commands in the Chain are either in Deep Sleep, but usually more appropriate, their HF Disabled flag is on (for example by using the Sleep Duration argument of t he Ve ri fy command). 2. If t here are Dat aSeals wit h different OrgIDs or Depart ment s, and you want to turn only to one of them, you should turn on the OIDf flag in the DataReader's SYS parameter. 3. If there are DataSeals with different ADIs, and want to turn only to a specific group, you should turn on the ADIf flag in the DataReader's SYS parameter.
