1Chapter 1IntroductionThe S556-EP InstaScan scanners and Dura-label Radio Frequency(RF) Identification Tags developed by SCS are state-of-the-art datagathering and inspection systems that combine sophisticatedInteractive Identification technology in a compact form factor. This uniquesynergy allows our system to integrate seamlessly into — and significantlyincrease productivity for — a wide range of applications and environments.This system consists of the following components:A scanner that is capable of writing information to and readinginformation from Dura-labels using a read/write head (antenna).The scanner conforms to FCC Part 90 specifications and can operatewith one to six externally connected antennas.Dura-label RF tags that contain information programmed by thescanner. These tags are designed to store information under extremelyharsh environments without requiring a battery, and the read/writeDura-labels can store a permanent record of multiple events andtransactions.Communications between the scanner and tags are conducted using arevolutionary two-way technology that provides superior advantages overconventional communication methods. The specific data beingcommunicated, and the amount of interaction you have with the scannerand tag, may be determined by your application.
2AdvantagesData-gathering systems such as bar code readers use one-waycommunication: a sensor reads information from a device, without anyinteraction between the two devices.Moreover, bar code systems are subject to line-of-sight limitations. As aresult, airborne contaminants such as dust, dirt, oil, and mist, as well aslabel damage and objects residing outside the line of sight, result ininefficient and erroneous results.The SCS Interactive Identification System overcomes these restrictions byusing state-of-the-art technology. This technology allows thescanner and tag to conduct ongoing two-way communicationsthat are not restricted by line-of-sight constraints.Figure 1. Interactive Identification Technology
3This unique capability allows:• Collective or selective data to be read from a single tag.• Collective or selective data to be read from multiple tags withoutrequiring sorting or unpacking.• Classes of tags to be filtered according to user-defined criteria.This technology employs a superior interrogation feature that enablesapplications to uniquely identify all tags in the scan field, withoutmisidentification or identifying the same tags multiple times.It also uses a robust protocol that maintains a uniform per-tag scan time,regardless of the number of tags in the scan field. The protocol providesa flexible software application interface that can be customized to thespecific needs of particular industries and markets.These unparalleled capabilities make our system an ideal solution forlogistics and warehousing, automatic sortation, pallet tracking, and anti-diversion/anti-counterfeiting applications.
4S556-EP InstaScan ScannerThe S556-EP scanner is designed for applications or configurations thatrequire the scanner to be a considerable distance from tags, or wherenumerous tags are required to be read simultaneously. Conveyor beltapplications are ideally suited to the scanner.The scanner provides six pairs of coaxial connectors for supporting up tosix external antennas. Each antenna plugs into its own set of connectorson the front panel of the scanner.Figure 2.S556-EP InstaScan Scanner

8Scanner FrontThe front panel of the S556-EP scanner has three LEDs that indicatepower, activity, and transmitter ON/OFF (see Figure 3). Table 1 describesthe meanings of the LEDs.The front panel also has an On/Off switch located below the three LEDs(see Figure 3).• In the ON position, the red Power ON LED should go ON, indicatingthat the scanner is receiving power.• If the OFF position, the scanner is not receiving power, even if theconnected to the power outlet.The front panel also contains three connectors. The lower connector is astandard DC power receptacle. The power cord provided with the scannershould be plugged into this connector and into the wall outlet. For moreinformation, refer to “Connecting to an AC Outlet” on page 14.The small multi-pin connector is the 9-pin RS-232 port. The RS-232serial port connector allows the scanner to communicate with a personalcomputer through the PC’s serial port. For more information on makingthis connection, refer to page 13.The large multi-pin connector is the 25 pin test connector. For moreinformation on this connector, refer to Chapter 6.Scanner RearThe S556-EP scanner rear panel houses a fan for cooling. Be sure toallow for space between the fan and nearby objects to prevent overheating.
9Table 1. S556-EP Scanner LED MeaningsLED Color Status Power ON Red ON = scanner is turned on and receiving power from external power supply Activity/Error Yellow Flicker = scanner detects tag information. Constant Flickering with no tag in the scanning field = (a) Noisy environment or possible interference, resulting in diminished tag reading. (b) Loose cable or bad connector Transmit On Green On = Scanner is transmitting RF signals.
10Scanner Installation StepsThe scanner installation consists of the following steps:1. Position the scanner – locate near desired antenna locations.2. Connect external antennas – see page 11.3. Place the antenna for optimum read/write operation –see page 12.4. Connect the scanner to a computer serial port or RS-232 –see page 13.5. Connecting to an AC outlet – see page 14.6. Configure the scanner - see page 15.7. Align the antenna – see page 18.
11Connecting External AntennasThe front panel provides six pairs of coaxial antenna Receive/Transmitconnectors. Each pair of connectors accommodates a single externalantenna. Figure 4 shows the external antenna connections to thescanner.IThe S556-EP can be used with fewer than six antennas. Installantennas sequentially, starting with the left-most connector pairs.Figure 4. Antenna ConnectionsCoaxial AntennaConnectorsCoaxial AntennaConnectorsInput/OutputCoaxial Cables
12Placing the AntennaAntenna placement is critical to ensuring that information is transmittedto and from tags accurately. Observe the following guidelines when plac-ing the antenna:Locate the antenna away from metal objects, microwave ovens,and other devices that may induce radio frequency interference.In addition, make sure there are no metallic surfaces between,or in relative proximity to, the scanner and tag. For additionalplacement considerations, refer to “RF Communications” onpage 23.When reading, the antenna should be placed no more than 60 inchesfrom the objects bearing tags. When writing, the antenna should be nomore than 22 inches from objects bearing tagsITags must reside within the scan field for at least 3 milliseconds forinformation to be retrieved from them.
13Connecting to a PC Serial Port or RS-232The scanner has a 9-pin female RS-232 connector that connects to aserial port or RS-232 connector on an IBM or compatible personalcomputer. The serial port can operate up to 57,600 bps.To make this connection, you need:An appropriately configured serial cable.One of the following adapters, if your computer’s serial port doesnot have a 9-pin connector:-A 15-pin to 9-pin adapter, if your computer has a 15-pin serialport connector.-A 25-pin to 9-pin adapter, if your computer has a 25-pin serialport connector.These adapters are available from most computer and electronicsstores.Use the following procedure to connect the scanner to your computer’sserial port.1. Attach the male connector on the serial cable to the 9-pin serialconnector on the scanner’s front panel (see Figure 3).2. Connect the other end of the cable to your computer’s serial port.Use an adapter, if appropriate, to make this connection.
14Connecting to an AC OutletThe following procedure describes how to connect the scanner to an ACOutlet.1. Verify that the On/Off switch on the scanner front panel is in theOFF position (see Figure 3).2. Connect the power cord to the AC receptacle in the scanner frontpanel (see Figure 3).3. Connect the other end of the power cord to the wall outlet.4. Set the On/Off switch to the ON position. The Power ON LEDlights.
15Configuring the ScannerThe following procedure will verify that the RS-232 link between thescanner and the computer is working correctly.1. Insert the supplied Series 5 Development and Demo Tools, Disk 1,into an available floppy disk drive.2. Open the “My Computer” icon on the desktop.3. Open the floppy disk drive (typically A:).4. Run the application “Setup.exe”5. Installshield will launch and guide you through the installation of theSeries 5 Tools onto your computer.6. Turn on the scanner and ensure that the antennas are connected tothe scanner. If you are using two or more antennas, connect eachantenna from left to right.7. Select the “Series 5 Test Tool” icon in the Series 5 tools folder fromthe start menu.8. If the scanner is attached to COM1 or COM2, it will be recognizedby the application automatically. In the application dialog, you willsee the text “found scanner (rev XX.XX) on COMX”.9. If the scanner is attached to COM3 or COM4, the application willnot recognize the scanner automatically. In the application dialog,you will see the text “Can’t find Scanner, use Manual Connect.”Select the appropriate COM PORT by pressing the down arrow inthe “Scanner <-> Host” frame. Hit the connect button. You shouldsee the text message “Connect: found scanner (revision XX.XX) onCOMX”.IIf you receive the error message “Can’t find scanner on COMX” referto page 27 for troubleshooting procedures.
1610. Look for the text “Scanner type = XXXX” in the application dialog. If“XXXX” is not “S556-EP”, select “S516” from the Scanner menu ofthe Series 5 Test Tool application.11. Look for the text “Mode = ...” in the application dialog. If the modeis not “Basic Function Test”, select “Basic Function Test” from theMode menu of the Series 5 Test Tool application.12. There are three tests you must run in order to confirm that the scanneris working correctly. These are “Read Test”, “List Test”, and “WriteTest”.13. Select “Antenna 1” button at the top of the Series 5 Scanner Testwindow. Hold a tag in front of the antenna while ensuring that yourhand is not between the antenna and tag, or covering the tag antenna.14. Position a tag within 60 inches of the antenna.15. Click the “Read Test” button. You should see the text “- Check Read:PASS –“ appear in the Test Results box. If the test fails, follow theinstructions given by the application.16. Remove all tags from around the antenna and click the “List Test”button. Wait two seconds. If the test is successful, you should seethe following text appear in the Test Results box.“- Check List –““List Start: OK”“List Stop: OK”“List Report: OK”“Found 0 tags:”“Place 1 tag in the field and run test again.”
1717. Each List Test is composed of three commands given to the scanner.If the test is successful, all these tests should say “OK” after the testname. The application will ask you to repeat the List Test with 1) Asingle tag, and 2) two tags in front of the antenna. The test is com-plete when the application successfully detects two tags.18. The Write Test requires a write - capable tag. Place the tag within 22inches of the antenna #1.19. Click on the Write Test button and observe the results in the TestResults box. If the test passes, you will see:“- Check Write –““Write: OK”20. If the test fails, follow the instructions given by the application. If yourepeatedly get the “Move tag closer to antenna” instruction, ensurethe tag is directly over the antenna and there are no objects betweenthe antenna and tag.21. For each antenna that is connected to the scanner, repeat steps 13-20 for that antenna.22. This completes the test of the scanner.
18Aligning the AntennaAfter verifying that the scanner is operating properly, use the followingprocedure to align the antenna(s). Aligning the antenna(s) ensuresoptimal performance.1. Connect the scanner to COM1 or COM2 and turn the power on.2. Run the application “Series 5 Test Tool” in the “Series 5 Tools”folder in the start menu.3. From the mode menu, choose “Antenna Alignment”.4. Select the antenna you wish to align with the available antennabuttons. Press the “Go” button.5. Move a tag into the “scanning area”, the point where you intendto scan.6. Adjust the antennas until the application indicates it detects a tag.You can find the complete scanning field by moving the tagaround. When the application detects a tag, the window will flashwith the message “Label Found”. Press the “GO” button again tostop the alignment test.7. If you have other antennas connected, you can select the differentantennas by using the antenna buttons on the top of the window.This completes the scanner installation procedure.
19Installing Dura-labelsDura-label RF tags have a diminutive form factor that allows them to beinstalled in areas that cannot accommodate conventional RF tags.In addition, Dura-labels can communicate with the scanner without havingto be in the line-of-sight. This unique combination provides tremendousflexibility when determining a location for placing tags.In textile applications, for example, tags can be inserted into the front tailof a shirt or the waistline of pants using a heat seal patch and a heatpress. Because this system does not require line-of-sight scanning, thetag does not have to be visible to the scanner.When considering locations for installing tags, make sure they are within60 inches of the scanner antenna for at least 3 milliseconds so data (16-bit word) can be read from the tag. Avoid locations where metal orwater is present because radio-frequency communication does notpenetrate metal and is absorbed by water.
20Reading Information from your Dura-labelsOnce you have installed your tags, and have set-up your scanner sys-tem, you are ready to begin.1. Run the “Series 5 Demo” application in the “Series 5 Tools” folder inthe start menu.2. The connect dialog box will appear, set COM Port to the port wherethe scanner is connected, Baud Rate to the highest value supportedby your computer and cable length. Set “# of Antenna” to theappropriate value then click the “Connect” button.3. After a few seconds, the main SCS Demo dialog will come up. Thescanner is in List-ID mode. As you move a tag into the field in frontof the antenna, you will see the ID of that label displayed underLabel ID.4. Try moving additional tags in front of an antenna. You can alsoreset the display with the Clear button.5. Double click on the ID of a tag to bring up detailed informationabout that tag. This will bring up a tag dialog where you can see thedata in each of the memory locations of the label. Additional usageof this dialog is described in the following section.
21Writing Information to Your Dura-labelRead/write tags can be written to using the scanner. Each bit of memoryis write once, read many (WORM). Meaning after you have written to aspecific bit, it is permanent and cannot be overwritten or erased. To addmore data to the tag you must write to a different bit. Another featureincluded with each user-writable word of memory is a Write-Protect bit.This bit allows you to protect an entire word (16 bits) after any or all ofthe bits have been written.1. Start the Series 5 Demo application as described in the previoussection.2. Move a tag into the field and double click on its ID to bring up thetag dialog.3. In the Write Protect frame, hit “Query All”. Any writeable memorylocation will become editable (white), while write protected memorylocations will stay gray.4. Move the mouse cursor over a memory location and click within thatlocation to edit it. Enter a new value and then hit “refresh” or movethe cursor to a different memory location and click. The applicationwill attempt to write the value you specified to the tag.5. The status of the tag will be displayed in the status box at the lowerpart of the screen. If the write was unsuccessful, the value in thememory location will change back to reflect the value actually storedthere.6. To write protect a memory location, move the cursor to a memorylocation and click the “Set” button in the Write Protect section. Thememory location will change from a white background to a graybackground to show that it is now write protected.
227. To write to a block of memory locations, use the commands in theblock section of the window. Enter the starting memory location inthe “From” window. Enter number of memory locations in the “Length”window. The ending memory location will be automatically calculatedin the “To:” window. Click the box to the left of the “Write” text andenter the data in the window below the “Write” command.8. To write protect the entire block, click the box to the left of the “WriteProtect” text.9. To complete the block write command, select the “Perform” button.10. To return to the List ID mode, click the “OK” button.Loading Your ApplicationAfter you install your system according to the instructions in this chapter,you can load your application and begin reading information from theDura-labels. Your application will determine the amount of interactionyou have with the InstaScan Scanner and Dura-labels.IIf you will be developing applications designed to interface to yoursystem, refer to the Software Development Disk for programminginformation.
23In general, devices that communicate using radio frequency, suchas your system , can be sensitive to signal interference and signalattenuation. This chapter provides tips for optimizing radio-frequency (RF) communications with your InstaScan and Dura-label.Topics in this chapter include:•Signal interference — see page 24•Signal attenuation/reflections — see page 25•Optimizing performance — see page 26Chapter 3RF Communications
24Signal InterferenceSignal interference is RF signals that interfere with the information beingexchanged between the tag and scanner. Signal interference can severelydiminish the scanner’s ability to read information from the tags. TheActivity LED on the scanner flickers constantly if it detects signalinterference.The source of the interfering signals may be:•An RF system, such as an RF local-area network (LAN) or anotherInteractive Identification system, located close to your system.•Security gates, garage doors, or similar devices that emit RF signals.•Appliances such as microwave ovens.The effects of these noise sources are localized and can be eliminated byrelocating the scanner and its antenna.Your system’s communication capabilities are significantly reduced whenthe noise level perceived by the system exceeds the strength of signalsreceived.
25Signal Attenuation/ReflectionsSignal attenuation is the loss of signal strength that occurs naturallyover distances, but which can also be caused by RF barriers in thesignal path.Examples of such barriers include:•Enclosed locations that have concrete walls, floors, and ceilings.•Metal surfaces surrounding the antenna or tag.•Water or other fluids surrounding the antenna or tag.Almost every object (furniture, partitions, and people) in the path of asignal causes some degree of attenuation. The effects can be minimizedby careful antenna placement.The reflection from metal or metallic surfaces behind the tag can alsoaffect signal attenuation. In some cases, this may increase the readdistance slightly, while inducing intermittent “dead” spots within the readfield that permit little or no communication between the scanner andtag.
26Optimizing PerformanceWhile it is not possible to predict how the system will perform in anygiven environment, observing the following guidelines will help optimizeperformance in your environments and applications:Carefully plan the placement of the scanner antenna.The antennas can be extended extended approximately ten feet fromthe scanner depending on cable length purchased for the application.I The scanner antenna should never be disassembled, altered,or modified except by an authorized technician. Any unauthorizedantennas modifications can void your warranty.Consider the environment’s RF characteristics, including constructionmaterials, office plan (closed or open), and the presence of windowsand ducting. The RF field pattern, and the reading distance, may beinfluenced by nearby metal objects, such as appliances, equipment,metal wall framing, and wire coat hangers.Ensure that objects containing tags are no more than 60 inchesfrom the antenna and remain in the scan field for at least 3milliseconds.To avoid mutual interference when installing more than one tag inthe same object, allow a sufficient distance between the tag. Themaximum interference occurs when tags within the same object arewithin two inches of each other and nearly equidistant from thescanner antenna.Never apply chemicals to the tags. Certain chemicals, such asalcohol, may have little or no effect at room temperature, but maybecome corrosive at higher temperatures.
27This chapter provides troubleshooting information you can use inthe unlikely event you have a problem with your system. CustomerService information and merchandise return instructions are includedin this chapter.Solving ProblemsThe following table identifies scanner and tag problems and providessuggestions for resolving the problem.Chapter 4TroubleshootingProblem Probable Cause SolutionThe Power ON LED does not light when you turn on the scannerThe AC outlet may not be working.Plug another electrical appliance, such as a lamp, into the outlet and turn it on. If the appliance does not work, plug the scanner into a different outlet.The AC outlet may be controlled by a wall switch.Set the wall switch to provide AC power to the outlet, or use an outlet to be controlled by a switch. Table 2. Problem Solving
28Problem Probable Cause SolutionThe Activity/Error LED does not light hen you configure the scanner.You may have a faulty tag.Try another tag.The scanner may be faulty.Use the Series 5 Test utilities to verify scanner operation (see "Configuring the Scanner" on page 15)The antenna cable may be faulty.Contact SCS Customer Service (see page 30).You receive an error message when configuring the scanner.The scanner may not be turned on.Verify that the Power ON LED is lit.The scanner’s serial port connection to your computer may not be secure.Verify the scanner-to-serial port connection. If you are using a serial port adapter, make sure the adapter connections are secure.The Series 5 Test programs are accesing a different a different Com Port than the one connected.Switch the serial cable to Com Port 1 or set the Com Port being used.
29Problem Probable Cause SolutionInformation could not be read from the tag.The tag may be outside of the scanning area.Make sure the tag is no more than 60 inches from the scanner.The tag may have passed too quickly past the scanner.Make sure the tag is in the scanning area for at least 3 milliseconds.No RF Power The supplied SCS Diagnostic tag may be used to verify that the scanner is transmitting RF power. When held within a few inches of the transmit antenna, the LED on the Diagnostic tag will glow Red, indicating the presence of the RF field.Same as above, but the Activity/Error LED flickers constantly.RF Interference is disrupting scanner-to-tag communications.See “Chapter 3-RF Communications” for suggestions on improving communications.

All products that are replaced shall become theproperty of SCS. Replacement products may be new or reconditioned. The warranty forreplacement or reconditioned product is the same as the equivalent newly purchasedproduct.SCS reserves the right to refuse to warranty repair any product that has been subjected toany abnormal electrical, mechanical, or environmental abuse.FCC Part 90 ComplianceThe FCC has established rules that permit the Scanner and Label system to be usedwithin acceptable bounds of radio frequency emissions. Your Scanner and Label systemcomplies with Part 90 of the FCC Rules.Operation of the Scanner and Label system is subject to the following conditions: Thisdevice may not cause harmful interference; This device may accept any interferencereceived, including interference that may cause undesired operation.This device complies with the limits for a Class B digital device, pursuant to Part 90. TheClass B limits help ensure that this device provides reasonable protection againstharmful interference in residential installation. This equipment generates, uses, and canradiate radio frequency energy and, if not installed and used in accordance with theinstructions in this manual, may cause harmful interference to radio communications.
41Radio Frequency (RF) exposure limitsfor operators of this deviceOperators of this device must have knowledge of their RF exposure conditions in orderfor the device to comply with FCC-adopted RF exposure limits for persons in the“controlled exposure environment”. The average RF exposure for operators is 5.0 mW/cm2, which requires them to maintain an estimated separation distance of 22 cm or 8.5”from the transmitter, while in operation. They should not remain closer than thesuggested distance for any continuous 6 minute interval. Holding “Tags” in front of thetransmitter for brief moments, at closer than 8.5” is allowed provided the averageexposure in any 6 minute interval is less than 5.0 mW/cm2. For example, if an operatorspends 50% of the time with his/her hands or body closer than 8.5” to the transmitterwhile spending the other 50% of the time at more than 15” away, the allowed RFexposure limits will be satisfied. Operators should use their own judgment to limit theirexposure to the allowed RF exposure limits with control of exposure conditions,separation distance from the transmitter, and duration of exposure. While this device isin operation, nearby persons who have no knowledge of being in the RF fields of thisdevice should be at least 20” away from the transmitter in order for this devise to becompliant with the FCC-adopted RF exposure limits.DisclaimerOperation of any radio transmitting equipment, including the Scanner, may interfere withthe functionality of inadequately protected medical devices. Consult a physician or themanufacturer of the medical device if you have any questions. Other electronicequipment may also be subject to interference.SCS Support (858) 485-91968:00 a.m. – 5:00 p.m. PSTEmail – techsupport@SCS-Corp.com
