ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 1 M-2405-0000 Rev. C- 1. Introduction Congratulations on your purchase of RFM’s ZigBee Developer’s Kit. The developer’s kit contains everything needed to get a two node ZigBee network up and running. Refer to Figure 1 for the contents of your kit. Figure 1. Developer’s Kit Contents The modules in this kit have been designed by RFM Engineers and embody the accumulated expertise gained over 20 years of RF design and implementation experience. Experience gained designing and implementing some of the most difficult RF networks around including nuclear power plant monitoring, medical patient vital signs telemetry and industrial asset tracking. This manual covers both the ZMN2405DK and the ZMN2405HPDK. The only difference between the two kits is the output power of the modules included. The ZMN2405 module provides 1mW of RF power while the ZMN2405HP provides 65mW of RF power (when coupled with a 2dB dipole antenna, the ZMN2405HP provides 100mW EIRP). RFM has six base module versions: ZMN2405, ZMN2405HP, ZMN2430, ZMN2430HP, ZMN2430A and ZMN2430HPA. All four modules use the same firmware and thus operate the same. The difference with the two HP versions is that they provide 65mW (100mW with the 2dB dipole antenna) of transmit power instead of the 1mW of the non-HP modules. The 2405 modules are solder bump while the 2430 modules are castellated. All versions are based on the CC2430 single chip module. Refer to the data sheets on the dev kit CD for details of the mechanical differences of the modules. In addition to being available as Coordinator, Router, and End Device versions, there are “A” versions that include a chip antenna. There are various flavors of ZigBee devices that this module must support, the Coordinator, the Router and the End Device. How these devices work and what their functions are in a Zigbee network are explained in detail is Section 2, Zigbee Networking. The development board can also be configured as an End Device by downloading the End Device code load provided as part of the kit. Programming the module is explained in Section 6.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 2 M-2405-0000 Rev. C- 2. ZigBee Networking ZigBee is a mesh networking and security stack that sits on top of an 802.15.4 MAC layer radio. 802.15.4 specifies the frequency bands, the number of channels, the spreading technique and the modulation method. ZigBee controls how data is routed between 802.15.4 physical layer radios, adding mesh and encryption capability along the way. There are three types of devices specified in ZigBee: a Coordinator; a Router and an End Device. The Coordinator and Router are sometimes referred to as Full Function Devices or FFDs. The End Device is sometimes referred to as a Reduced Function Device or RFD. Since an FFD can be a Coordinator or a Router, this manual will use the Coordinator, Router and End Device names. The Coordinator is responsible for setting the channel for the network to use, making its presence known to Routers and End Devices, assigning network addresses to Routers and End Devices and keeping the routing tables for the network that are necessary to route data from one ZigBee device to another in the same ZigBee network. Each network must have one and only one Coordinator. Without a Coordinator, a network cannot form. Typically, although it is not a requirement, the Coordinator will function as the gateway or takeout point for applications where data from the ZigBee network will be sent off the network and will be received from devices off the network. The Router, as its name implies, is responsible for routing data from other Routers or End Devices to the Coordinator or to other Routers closer to the Coordinator. The Router can also be a data input device, either serially or through the I/O pins of the module. The End Device can only communicate with the Coordinator or a Router. An End Device cannot communicate directly with another End Device. Communication between one End Device and another End Device must go through the Coordinator or a Router and may go through one or more Routers. Figure 2 depicts a typical ZigBee network with two levels of Routers. The box labeled C represents the Coordinator, the boxes labeled R represent Routers and the boxes labeled E represent End Devices. As can be seen from the diagram, each End Device has multiple potential communication paths. The most likely path is a solid line with backup paths indicated with dashed lines. From this Figure it is seen how End Devices only communicate with Routers and the Coordinator while Routers can communicate with End Devices, other Routers or the Coordinator. The Coordinator can communicate with Routers and End Devices.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 3 M-2405-0000 Rev. C- Figure 2. Typical ZigBee Network 2.1 Forming a Network The Coordinator is typically the first element powered up. The Coordinator will listen on the first channel of the set of channels that has been specified for it to use in forming a network. If the Coordinator detects RF energy on that channel, it will move to the next channel in the channel set until it finds a clear channel. If a clear channel cannot be found, the Coordinator will indicate an error. If a PAN ID has been specified, the Routers and End Devices will look for a Coordinator with the specified PAN ID. If a Coordinator is not found on a channel, or one is found, but has the wrong PAN ID, the ZigBee device will go to the next channel on its channel list until a satisfactory Coordinator is found. The Coordinator will assign each device that identifies itself to the Coordinator a 16-bit network address. This 16-bit network address is used to route data within the network. Each ZigBee device has a unique 8-byte MAC address just as in an Ethernet network. The 16-bit network address can and will change every time the Coordinator is power cycled unless the Static Network mode is enabled. (Refer to Section 2.6 for details). The network is now formed. If the Routers and End Devices have been configured to transmit data on their own, they will begin doing as they have been told. If the Coordinator is to be used as a gateway too, it is typically necessary to let the application communicating with the gateway to know what devices are on the network. ZigBee provides a discovery command which returns from the Coordinator/gateway, the 16-bit network addresses of all devices associated in the network. The application then must request the 8-byte MAC address and optionally the “Friendly Name” of each device associated with the network. Once the devices associated with the network have been discovered and the MAC addresses obtained, the application can address data and commands to individual devices on the network.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 8 M-2405-0000 Rev. C- the ZigBee device will stop trying to re-associate with its original network address and re-associate with the network as if it had never belonged. Static Network Addresses cannot be used in a mobile environment as it is expected and desired that nodes will associate and re-associate using different parents. In the event when Static Network Addresses are being used, if a parent is no longer available, the node device will associate and receive a new network address. Link Announcements To prevent the application from periodically rediscovering the network again to learn the network addresses - most of which will not have changed - RFM has implemented Link Announcements. Link Announcements are always enabled. Any time a node associates with a network whether it is the first time or the fifth time, and regardless of with which parent device it associates, a Link Announcement message is sent to the coordinator. The Link Announcement message includes the network address of the node joining the network. The GET IEEE command can be used to determine the MAC address of the joining device.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 9 M-2405-0000 Rev. C- 3. Getting Started Once you have identified all the components of your kit, connect either the 6dBi patch antenna directly to the RF connector on the development boards or the RF cable and 2dBi dipole antenna. It is not necessary to use the same antenna on both boards. 3.1 Installing ZBDemo The next step is to copy the ZBDemo program onto a computer. The ZBDemo program is on the Software and Manuals CD in the Software directory included with the kit. Copy the file zbdemo.exe onto the hard drive of the computer and remember into which directory it was copied. 3.2 Installing USB Drivers If a USB port is to be used to communicate with the development board, the drivers for the USB adapters must be installed on the PC. The USB drivers are on the Documentation and Software CD under the Drivers folder. When the computer detects the presence of the hardware, the “Add New Hardware Wizard” box will appear. Click on “Next” and follow the prompts. Refer to Section 5 for step-by-step instructions. 3.3 Running ZBDemo One development board is setup as the Coordinator and the other development board is setup as a Router. Connect the Coordinator to either the USB or RS-232 serial port of the computer. Use either the wall-mount power supply or a 9V alkaline battery. It is not necessary to use the same power type for each radio. Apply power to the Coordinator first and verify the Power LED is on. When the Coordinator has found that the channel is clear, the Link LED on the Coordinator will glow green. Once the Coordinator has turned on the Link LED, the Router can attempt to associate with the Coordinator. Once it has associated with the Coordinator, the Link LED will glow green. Wait until the Link LEDs on all radios are glowing green before continuing. Start the ZBDemo program by double-clicking the ZBDemo icon on the computers’ desktop.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 10 M-2405-0000 Rev. C- Click the Connect button on the ZBDemo screen. A window will open showing the communications parameters to be used to communicate with the Coordinator. Select a serial port from the drop down menu. Selections that are available will be marked as “OK”, those unavailable will be marked as “N/A”. 38,400 is the Default baud rate. This window changes the PC Comm Port parameters but not the development board. The Comm Port Settings dialog is pre-loaded with default settings. In most instances, simply clicking OK will allow ZBDemo to find the radio and load the main program window. If, however, the default settings are incorrect, the radio will not be found. This screen allows you to connect to the radio using two methods.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 11 M-2405-0000 Rev. C- The first is to use the drop down menus to change the default settings for Comm Port, Baudrate, Parity and Stop Bits to the correct values. Obviously, this assumes you know which settings the radio is using. If, however, those parameters may have been changed and are not known, a second method is available. The Auto Detect function works this way. If set to FALSE, once OK is selected, the program uses the default settings to try to communicate with the radio. If set to TRUE, the program will begin a systematic process beginning with the first valid port (COM 1 in most cases) then will cycle through each baud rate, then each parity setting, then each stop bit setting finally changing to the next available COM port and repeating the process until a radio is found. Once the radio has been found, click OK and after a few seconds, information about the ZigBee module in the Coordinator will be displayed in the Local Radio column along with its 8-byte MAC address. The Status condition of CONNECTED indicates the computer has detected the development board as shown below. Click on the Discover Radios button. This will cause the Coordinator to request information about the Router development board.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 12 M-2405-0000 Rev. C- Router This information will be displayed in the Radio 1 column of the ZBDemo program and the type listed as “Router” as shown below. Note: This assumes the development board is configured as a Router. If the development board has been reprogrammed as an End Device, refer to the next section. The Status for Radio 1 will be LINKED and the LQI (Link Quality Indicator) will show the relative strength of the link. The columns for Radios 2, 3 and 4 will be grayed out with a Status of Not Linked. Repeat the above steps on the other computer for the development board.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 13 M-2405-0000 Rev. C- After completing the steps, the Router information will be displayed in the Local Radio column and the Coordinator information will be displayed in the Radio 1 column as shown below. There are Poll Radio checkboxes at the bottom of each Radio column that enable periodic polling of the radio’s parameters. In order to see changes made to the state-change devices on the development board, turn on continuous polling by clicking the Start button under the Refresh Delay field. A setting of 0 seconds in the Refresh Delay field will continuously poll the Radios with the Poll Radio box checked. Longer Refresh Delay settings can be set using the up and down arrows to the right of the Refresh Delay field, or the number can be highlighted and a value entered. Once the Start button is pressed, it changes to a Stop button. Clicking on the Stop button will end the polling process.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 14 M-2405-0000 Rev. C- End Device If you have configured the development board as an End Device, this information will be displayed in the Radio 1 column of the ZBDemo program and the type listed as “End Device” as shown below. The Status for Radio 1 will be LINKED and the LQI (Link Quality Indicator) will show the relative strength of the link. The columns for Radios 2, 3 and 4 will be grayed out with a Status of Not Linked. Repeat the above steps on the other computer for the End Device.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 15 M-2405-0000 Rev. C- After completing the steps, the End Device information will be displayed in the Local Radio column and the Coordinator information will be displayed in the Radio 1 column as shown below. There are Poll Radio checkboxes at the bottom of each Radio column that enable periodic polling of the radio’s parameters. In order to see changes made to the state-change devices on the board, turn on continuous polling by clicking the Start button under the Refresh Delay field. A setting of 0 seconds in the Refresh Delay field will continuously poll the Radios with the Poll Radio box checked. Longer Refresh Delay settings can be set using the up and down arrows to the right of the Refresh Delay field, or the number can be highlighted and a value entered. Once the Start button is pressed, it changes to a Stop button. Clicking on the Stop button will end the polling process.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 16 M-2405-0000 Rev. C- In the lower left portion of the main ZBDemo window, there are two additional buttons, Show ZigBee Tree and Show Event Log. The Event Log is a chronological listing of the events that have occurred on the Zigbee network as shown below. As you can see, the log shows the date and time of the event, along with the network address of device the event was received from, the Cluster, Offset and Length (in bytes) of the event and finally, the data received. The Clear button allows you to remove all recorded events from the window and have the logging start again. The Zigbee Tree button opens the Childform window which is an expandable representation of the devices that makeup the Zigbee network as shown below.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 17 M-2405-0000 Rev. C- There are checkboxes at the bottom of the window (Show MAC Address, Show Friendly Name, Show Device Type) that allow you to choose the items listed for each device in the network. You can check all or not check any. There is also a Poll Rate field that allows you to enter a polling time period, this number is in milliseconds, i.e. 1000 would equal 1 second. The Poll Devices button on this window can be used in conjunction with the main ZBDemo screen to automatically and sequentially poll ALL current network devices without having to individually select devices to load into the Radio 1 – 4 columns. This can be useful on networks were there are substantially more radios in the network than can be displayed in the four available Radio columns. Notice there is a + sign to the left of the Coordinator line. Clicking on that sign will expand the tree so that all the network devices connected to the Coordinator will display as shown above. Double click on any line to open the configuration screens for that device. Clicking on the Rescan button will go out and scan the network for any changes, then display those changes in the Childform window.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 18 M-2405-0000 Rev. C- If you want to send text messages back and forth between radios, a second serial port – either RS232 or USB – is needed on the computer or a second computer is needed. Two Zigbee USB devices cannot be attached to the same PC. This is due to the USB drivers. Click on the Serial Comm button in the lower right hand corner of the ZBDemo main screen and the String Messaging Demo box will open. There are four fields/windows in this box: the Destination Address window top left of the box, the Incoming Data field top right of the box, the Messaging Display window in the middle of the box; and the Text to Send window at the bottom of the box. The Clear button allows you to clear the contents of the messaging display window. To send a text string to the other radio, simply click on the Send button which will send the text entered in the Text to Send field to the other radio. Data sent by the local radio will appear in the messaging display window indicating what the Local radio transmitted as shown below.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 19 M-2405-0000 Rev. C- Data received from the other radio will be displayed in the messaging window and labeled according to the Incoming Data field selection. Incoming Data can be labeled using the Friendly Name, the MAC Address or the Network Address as shown below. The String Messaging Demo functionality works the same on the other computer connected to the Router board. 3.4 Communicating without ZBDemo Packets are used to send and receive data thus unformatted data packets cannot be sent to the UART Port without first putting the module in Transparent Mode. Details on packet format and structure can be found in Section 8.8, Serial Protocol. For details on using Transparent Mode, see Section 8.2.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 20 M-2405-0000 Rev. C- 4. The Development Board This section describes in detail all the features and functions of the development board that makes up the developer’s kit. The development board as it comes from the factory is labeled as a Router on the bottom of the board. Additional Router or End Device development boards can be ordered from RFM. A block diagram of the development board is shown below: Figure 3. Development Board Block Diagram The USB and RS-232 interface circuits convert standard level signals into 3.3V transmit and receive data signals. Only one input can be used at a time. If a USB connection is present, the RS-232 input will be electrically locked out. Note that there is no hardware flow control implemented on the RS-232 input. A standard RJ-11 connector is provided for the RS-232 connection. The development board can run off either a 9Vdc power source or a 9V alkaline battery. The supplied wall-mount DC power supply connects to the DC power connector located next to the USB connector. The 9V alkaline battery connectors are located on the bottom of the board underneath the Power LED. A JTAG header is provided for situations where custom profiles or module code is being developed and the module will be programmed without using the bootloader code resident in the module. All of the ZMN2405HP module pins, except Reset, are brought out to connectors on the board. This facilitates connecting the module to other devices without having to integrate the module into another circuit. The pinouts of the connectors are listed below and are included in the board silk screen for JP1 and JP2.

The GPIO LEDs, Switches, Potentiometer and Thermistor are provided for demonstration purposes. These components can be read and written to using the ZBDemo program. The switches are momentary SPST switches and close to ground when pressed. The thermistor is used to vary an input voltage to the ADC X input with a maximum input voltage of 3.0 volts. Similarly, the potentiometer is connected in a resistor divider network to vary an input voltage to ADC Y input which can vary between ground and Vcc (~3.3V). Refer to the board schematics at the back of this manual for more details. To connect ADC X or ADC Y to off-board signals, disconnect the thermistor and potentiometer from the module inputs by removing JP3 for the potentiometer and JP4 for the thermistor. A group of four status LEDs are provided to allow board activity to be monitored. The LED functions are provided in the table below. LED Function Link On the Coordinator, illuminates when a clear channel has been detected and the Coordinator is ready for other devices to associate with it. On Routers and End Devices, illuminates when they have associated with a Coordinator. Activity Indicates RF data activity.

ZBDemo This sections details the features and functions of ZBDemo and provides some information on what is going on behind the GUI. ZBDemo does not need to be installed, only copied onto the computer to be connected to the developer board. The opening screen is shown below: ZBDemo can display up to 5 devices including the Coordinator. Regardless of whether or not a radio is set up as a Coordinator or not, the information for a radio connected to the computer running ZBDemo will always be displayed in the Local Radio column. The Coordinator to which the local radio is associated will have its information displayed in one of the Radio columns. To identify the Coordinator, it is necessary to look for the MAC address on the label on the bottom of the PCB. Routers have their MAC address in the same location.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 24 M-2405-0000 Rev. C- When the Connect button is clicked, the Comm Port Settings box opens. Note: Be sure to close all resident programs that use the Serial port such as any portable digital assistant syncing software (ex: Palm’s HotSync) prior to running ZB Demo. The Comm Port Settings dialog is pre-loaded with default settings. In most instances, simply clicking OK will allow ZBDemo to find the radio and load the main program window. If, however, the default settings are incorrect, the radio will not be found. This screen allows you to connect to the radio using two methods. The first is to use the drop down menus to change the default settings for Comm Port, Baudrate, Parity and Stop Bits to the correct values. Obviously, this assumes you know which settings the radio is using. The Comm Port drop down menu will display a list of Comm port selections from 1 to 16. Selections that are valid will be marked as OK. If an invalid selection is chosen, when the OK button is clicked, an error message will be displayed indicating that the selected Comm Port is not valid. If a valid Comm port is selected, but the radio is not connected to that port, a baud rate error message will be displayed saying a radio could not be detected at the proper baudrate. If this message is received, select another Comm Port and try to connect again. If, however, the default parameters have been changed and are not known, a second method, Auto Detect, is available. The Auto Detect function works this way. If set to FALSE, once OK is selected, the program uses the default settings to try to communicate with the radio. If set to TRUE, the program will begin a systematic process beginning with the first valid port (COM 1 in most cases) then will cycle through each baud rate, then each parity setting, then each stop bit setting finally changing to the next available COM port and repeating the process until a radio is found. Once the radio has been found, click OK and after a few seconds, information about the ZigBee module in the radio will be displayed in the Local Radio column along with its 8-byte MAC address. The Status condition of CONNECTED indicates the computer has detected the radio as shown below.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 25 M-2405-0000 Rev. C- ZBDemo works the same whether connecting to an RS-232 serial port or a USB port. On most computers, the USB Comm Ports have higher port numbers than RS-232 ports. Even on computers without an RS-232 serial port, the USB Comm Ports are numbered something other than 1 or 2. If a USB port is to be used, the drivers for the USB adapters must be installed on the PC. The USB drivers are on the Documentation and Software CD under the Drivers folder. When the computer detects the presence of the hardware, the “Add New Hardware Wizard” box will appear. Click on “Next.” The next dialog box will ask what Windows should do. Click on the “Search for the best driver for your device” button and then click on “Next.” The next dialog box will ask where Windows should search for the driver. Put the included software CD in the computer and enter the drive letter for your CD drive. Click on the “Browse” button to the right of the window. A window will pop up displaying the contents of the CD. Double-click on the folder named “Drivers.” Click the “Next Button.” Windows will indicate it has found the driver FTDIBUS.INF on the diskette. Click on the “Next” button to begin the driver installation. When Windows has finished the installation the messages “USB High Speed Serial Converter” and “Windows has finished installing the software that your new hardware device requires” will be displayed. Click on the “Finished” button to close the Wizard. When ZBDemo has established a connection with a radio, the information for that radio will be displayed in the Local Radio column as shown below.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 26 M-2405-0000 Rev. C- The Status of CONNECTED indicates the radio is communicating with ZBDemo and has nothing to do with whether or not the radio is part of a ZigBee network. Even when the radio is configured as a Router or End Device, the Status will indicate CONNECTED. Each radio will have a different Network Address. As radios are discovered, they will be made available in the Network Address drop down menus. This allows you to selectively display any individual radio’s parameters using the Network Address drop down menu. For situations in which more than 5 radios are being used, this feature allows you to view and/or reorganize how the parameters are displayed. There are Poll Radio checkboxes at the bottom of each Radio column that allow the radio to be periodically polled for information when the Start button is pressed under the Refresh Delay field. A setting of 0 seconds in the Refresh Delay field will continuously poll the Radios that have Poll Radio checked. Longer Refresh Delay settings can be set using the up and down arrows to the right of the Refresh Delay field, or the number can be highlighted and a value entered. Once the Start button is pressed, it changes to a Stop button. Clicking on the Stop button will end the polling process. 5.1 Discover Radios Once the ZBDemo has connected to the board, if the Link LED is illuminated, ZBDemo can discover the nodes that are part of the network. The Discover Radio button causes up to four radios that are part of the same ZigBee network as the Coordinator to be displayed at any one time and will read the status of the various components of each radio. Using the Network Address drop down menu, additional radios can be selected and their parameters displayed and/or changed. The status of each Radio will be LINKED. The MAC Address window will display the actual MAC address of each radio and the Switch, LED, Thermistor and Potentiometer windows will display the status of each component on the development board. The values that were present when the Discover Radios button was clicked will be displayed but the values will not be Refreshed until the Start button has been clicked. The Discover command can be issued from a Coordinator, Router, or End Device. 5.2 Refresh Delay The Refresh Delay sets the frequency with which information from all radios, local and remote, is updated. The frequency can be adjusted in one second increments. A value of zero corresponds to a continuous updating. Since an updating of each radio requires a number of individual read and write commands, it may take a second to update each radio even if the Refresh Delay is set to zero. This time is a function of Windows and ZBDemo and not the ZigBee module. Once the Refresh Delay has been chosen, click on the Start button to begin the updating. The status bar on the bottom left corner of the ZBDemo screen will indicate the progress being made by the program. When ZBDemo is updating the radio data, the Start button will change to a Stop button. When ZBDemo is idle, the Stop button will return to the Start button. If the Poll Radio box is unchecked for a radio, that radio will not have its information updated. 5.3 Switches The Switch0 and Switch1 windows display the state of the two momentary push button switches on the development board. When the switches are open, the window will display 0x01. When

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 27 M-2405-0000 Rev. C- the switches are closed, the window will display 0x00. Note that ZBDemo will not update changes in either the Local Radio or the remote Radios until the Refresh is started by clicking on the Start button under the Refresh Delay window. 5.4 GPIO LEDs The LED0 and LED1 windows allow the GPIO2 and GPIO3 module lines to be driven high or low to turn the LEDs on or off respectively. The LEDs are turned on by entering 1 in the window and turned off by entering a 0 in the window. As before, ZBDemo will not update changes in either the Local Radio or the remote Radios until the Refresh is started by clicking on the Start button under the Refresh Delay window. 5.5 Thermistor, Potentiometer and Analog to Digital Inputs The Thermistor window displays the 10-bit ADC reading of the ADC X channel. Changes in temperature will cause the value displayed to change if ZBDemo has been put into update mode by clicking on the Start button under the Refresh Delay window. Similarly, the Potentiometer window displays the resultant 10-bit ADC value of the voltage divider created by the pot. Changing the voltage by adjusting the pot will change the value displayed in the window if ZBDemo is refreshing the data as above. The potentiometer and thermistor can be removed from the circuit by removing the headers from JP3 and JP4 respectively. 5.6 Digital to Analog Outputs The PWMA and PWMB windows allow adjusting the duty cycle of the PWM outputs. These outputs are fed into an RC network for low pass filtering to generate an analog voltage. The allowable values are 0x0000 to 0xFFFF. 5.7 Children’s Network List Coordinators and Routers can be parents to other devices in the network. The Coordinator will always have children as long as there is at least a second device in the network. Routers may or may not have any children and End Devices cannot have children. The drop down menu will display the network address of all children associated with the radio in that column.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 28 M-2405-0000 Rev. C- 5.8 Show ZigBee Tree The Show ZigBee Tree button displays a hierarchical view of the network. The Coordinator is displayed at the top. When there are other devices in the network, a plus sign will be displayed under the Coordinator. Clicking on the plus sign will expand the ZigBee Tree displaying the Routers and End Devices directly associated with the Coordinator. Any Routers with children will also have a plus sign. Clicking on the plus sign will expand the children list of that Router. This will continue until the entire network is displayed. The default is to display the MAC address of the network nodes but you can have the network addresses and friendly names displayed by checking the corresponding boxes. 5.9 Config The Config button brings up the Module Clusters dialog which allows configuration parameters of each radio to be modified. There are seven possible tabs across the top of the dialog window that correspond to the Zigbee clusters; Config, Config Enable Options, Module I/O, Network, Diag, RF and End Device. However, the End Device tab will only appear if the applicable radio is configured as an End Device. It is shown in the screens below for informational purposes. A Broadcast Mode checkbox appears in the lower left hand side of each Cluster’s tab that sends the applicable Cluster’s information to all radios. Once values have been modified, click on the Apply button to write the new values in the module. If a reset of the module is required for the changes to take effect, the Radio Reset dialog will be displayed as shown below. Click on Yes to reset the radio, Click on No to have the changes take affect on the next power cycle. Note: See individual Cluster tables to determine if a Radio Reset is required.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 29 M-2405-0000 Rev. C- 5.9.1 Config Tab The Serial Baudrate sets the communication rate for the UART port of the module. Changes take effect immediately upon clicking Apply. The Model Number field shows whether the device is a Coordinator, Router or End Device. Friendly Name is a 16-byte field that allows user-defined names to be assigned to modules for easier identification in the field. It allows the user to assign applicable names to each radio in the system, i.e. Main Office for the Coordinator and Pump Well 1 for the Router out on the site and so on. Sleep Mode This is used on End Devices Only. Checking this box will configure the module as a battery-powered sleeping node. The default sleep mode is Timer Sleep. If Interrupt Sleep mode is desired, it can be selected under the Confg Enable Options tab. This setting should be configured before the device joins the network. If it is changed after the device has joined the network, all devices in the network must be power cycled or reset, starting with the coordinator, to insure the network functions properly. Device Mode This is currently Read Only. On read back it will be 0x00 for a Coordinator, 0x01 for a Router, and 0x02 for an End Device. Transparent Mode A check is this box implements Transparent Mode and allows data without the CSM packetization to be transmitted. Any data appearing on the serial input will be transmitted to the coordinator. Data received by the device will also be output by the module without the CSM packetization. Once you enter Transparent Mode, ZBDemo will no longer work since it is expecting data to be in CSM packets. See Section 8.2 for details on protocol mode. Transparent Mode is only for a Router or End Device.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 30 M-2405-0000 Rev. C- Reporting Mode Checking this box enables the device to send the module I/O cluster in an EVENT packet to the coordinator at an interval determined by the Reporting Rate. This mode works for all device types. Reporting Rate This is a 32-bit value that sets the reporting interval of the reporting mode. The resolution is in 1ms increments but with the accuracy of the smaller of the Check Parent Rate and 500ms. The value may vary anywhere from 1000ms (0x000003E8) to 49.7 days (0xFFFFFFFF). If an attempt to set it less than 1000ms is made, an INVALID_RANGE error packet will be returned. Firmware Version is a read-only register that identifies the firmware revision level. 5.9.2 Config Enable Options This page allows you to enable Device Message Options for the various GPIOs (general purpose inputs/outputs). Putting a check in the Enabled box allows the device to issue various messages when GPIOs 0 through 3 are set as interruptible inputs. When the input changes from high to low, one message (defined by the radio buttons under Device Message Options) will be transmitted to the gateway (default is the Coordinator) Device Message Options allow you to individually set what types of messages are initiated by the GPIOs 0 through 3. The options are: • Button Message - This message is simply an Event message that describes the particular GPIO input state. It should always be 0b0 since the interrupts are falling edge triggered. • Module I/O Message - This message is an Event containing the current data from the entire Module I/O cluster. This is the same data that is sent when the Reporting Mode is enabled. • Device Announcement - This message will force the device to re-register with the gateway (coordinator) by sending a device announce packet.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 31 M-2405-0000 Rev. C- Device Options Settings allow you to check or uncheck the following settings: • Device Registration - By checking this box, the device will output a Device Registration packet for every device that joins its network. The box is checked by default. • Interrupt Sleep - If the device is an End Device, checking this box when the Mains Powered box is not checked under Power Source on the Configi tab, puts the module into Interrupt Sleep where the module can only be awakened by an interrupt on one of the GPIO lines. In this mode, the module will not perform a Check Parent operation until it is awakened by an interrupt. • Link Announcement - By checking this box, the device will output a Link Announce packet when it has registered (Routers and End Devices) or formed a network (Coordinators). The Link Announce packet is output on the module’s UART port. The bit is enabled by default. • I/O Sleep State Enable – Checking this box causes the module to set the module GPIO pins to the state selected for each GPIO on the End Device tab. This feature is intended to be used for sleeping End Devices to avoid conflicts with attached circuits when the module goes to sleep. Improperly setting the I/O Sleep State of a GPIO can cause a significant increase in sleep mode current consumption due to sneak paths from the module pin through other circuits to ground or power. 5.9.3 Module I/O Tab The GPIO Direction allows you to individually set GPIO0-5 as either inputs or outputs. The GPIO Init is a non-volatile setting for the power up value of all the GPIO pins set as outputs. If a pin is set as an input this setting has no effect. Each time a reboot occurs (power cycle, command, etc.) this will be the default output level. The GPIO Interruptible register allows GPIO0..GPIO3 to be used as interrupts to wake a module not configured for Mains Powered. If Interrupt Sleep Mode is enabled but no GPIO line is set as interruptible, the ZigBee module will return an error.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 32 M-2405-0000 Rev. C- DAC A Init and DAC B Init initialization registers are non-volatile settings for the analog output values after a reset command or power cycling. Each time a reboot occurs this will be the default output level for either DAC A or DAC B. 5.9.4 Network Tab The MAC Address is the unique IEEE address of the device and is set at the factory. The Network Address is a read-only register that contains the network address assigned to the device by its parent. It cannot be changed by a user or pre-configured in any way. If the module is not linked, its value will be FFFF. A check in the Static Network box allows the user to force the device to remain in the same network configuration from power-up to power-up. Uncheck the Static Network box and the device can join (or configure) the network in a different manner every time it restarts and thus, Network Addresses will change. Refer to Section 2.6 for details on Static Network Addresses. Gateway Address This is the destination network address for data sent to a module through its UART port in Transparent Mode. Currently, this is set for the Coordinator and cannot be changed. A PAN ID is required for the Coordinator and can be any 14 bit number, i.e. 0x0000 to 0x3FFF. In order for the Router to link to the Coordinator, its PAN ID must match the PAN ID on the Coordinator. Setting a the PAN ID of a Router to 0xFFFF will allow a Router to connect to any Coordinator on the same RF Channel. Setting 0xFFFF on the Coordinator causes it to pick a random value.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 33 M-2405-0000 Rev. C- Link Status is a read-only register that provides information about the device’s link status. (Update button refreshes Link Status.) LinkStatus Value Description 0x01 Device is initialized, but not connected 0x02 Device is discovering PANs to join 0x03 Device is joining a PAN 0x04 Device has joined but is not yet authenticated by the Trust Center 0x05 Device has been authenticated and has joined the network as an End Device 0x06 Device has been authenticated and has joined the network as a Router 0x07 Device is starting a network 0x08 Device has started a network as the coordinator 0x09 Device has been orphaned 5.9.5 RF Tab The Channel Set selects the RF channel(s) the module can use. Any number can be checked or unchecked as long as at least one channel is selected. If no channels are selected, when you click on Apply, an error message will display. Simply click in a box to add a check mark. Clicking on a box that already has a checkmark will remove it. The Coordinator listens on the first channel of the channel(s) that have been specified in the Channel Set field. If it detects RF energy on that channel above the Network Formation Threshold level, it moves to the next channel in the channel set list until it finds a clear channel. Once a channel has been found, text will display in the Status text window in the lower right part of the main ZBDemo window indicating that a network has been formed. If a clear channel cannot be found, the Link LED will not be lit and no text will display in the Status text window. Once a clear channel has been found, the Coordinator will listen for other devices seeking to associate. See Section 8 for a more detailed explanation.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 34 M-2405-0000 Rev. C- Transmit Power can be set to the following levels; Nominal or -1dB, -3dB, -5dB, -7dB, -10dB, -15dB or -25dB from the nominal. Nominal transmit power for the ZMN2405HP module is +18dBm at the RF connector thus setting transmit power to -10dBm will result in +18dBm – 10dBm = +8dBm at the RF connector. Nominal level for the ZMN2405 module is 0dBm at the RF connector. The user may find it necessary to change the level if for instance, regulations require lower output power and/or when using a high gain antenna. The Network Formation Threshold variable is a signed 8-bit value(0xFF = -1) in dBm which is used to vary the threshold around a default of -40dBm. Energy detected above the corresponding power level will stop the Coordinator from starting a PAN in the tested channel. This is helpful in forcing a network in an area with a lot of RF noise. The equation is: Threshold = -40dBm + Network Formation Threshold 5.9.6 End Device Tab The GPIO Sleep Direction allows you to control the direction of the GPIOs during a device's sleep period if the I/O Sleep State was enabled on the Config Enable Options tab. This enables the user to provide alternate configurations during sleep that will help minimize current consumption. Sleep I/O State is used to set the output state of the GPIOs during a device's sleep period if the I/O Sleep State was enabled on the Config Enable Options tab. This also enables the user to provide alternate configurations during sleep that will help minimize current consumption. Check Parent Rate - This setting controls the rate at which a Timer Sleep Mode End Device will awaken and ask its parent for any queued messages. Because an Interrupt Sleep End Device must request stored messages while it is awake, this setting controls that rate while the device has been externally awakened. The setting resolution is in milliseconds and 0x0000 is an invalid setting.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 35 M-2405-0000 Rev. C- Wake Duration - This setting controls the length of time a module will remain awake when it wakes due to Check Parent timer. The default setting is 100 milliseconds. The minimum length of time is 30 milliseconds and the maximum duration is 65.5 seconds. 5.10 Serial Comm Click on the Serial Com button to bring up the text messaging window as shown below. There are four fields/windows in this box: the Destination Address window top left of the box, the Incoming Data field top right of the box, the Messaging Display window in the middle of the box; and the Text to Send window at the bottom of the box. The Clear button allows you to clear the contents of the Messaging Display window. The Destination Address window is used to select the ZigBee device to which to send a text string. The drop down menu will display the Long Network Addresses of the devices that were found to be part of the network through the Discover command. The Long Network Address is the two bytes displayed in the Network Address field preceded by 80:00:00:00:00:00. Example: If the Network Address is 0x0001, the Long Network Address will be 80:00:00:00:00:00:00:01. Select the Long Network Address of the desired device. ZigBee uses a packet format to send data. Rather than waiting for a long pause between keystrokes to determine the end of the data, ZBDemo requires the text be entered in the Text to Send window and the Send button clicked. ZBDemo can send a maximum of 68 bytes per packet thus the maximum number of characters that can be sent in a single packet is 64. When the String Messaging window is open, the radio information will not be refreshed.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 36 M-2405-0000 Rev. C- When the Send button is clicked, the text in the Text to send window will appear in the chat window after a LOCAL> prompt. When data is received by the local board from a remote ZigBee device, that string will be displayed in the chat window after a > prompt. The > prompt is labeled according to the selection designated in the Incoming Data drop down menu as shown below. In addition to Friendly Name, MAC Address or Network Address can be selected.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 37 M-2405-0000 Rev. C- 6. Programming the Module Firmware The ZMN2405HP developer’s kit includes three code loads which can be programmed into the ZMN2405HP module. All the modules come programmed from the factory, but RFM provides the capability to change the code in the module. The ZMN2405HP has bootloader code which allows the module firmware to be programmed through one of the two serial connections to the development board. The bootloader code removes the need for a JTAG programming device. Three files are provided in the Code Loads directory of the Software and Manuals CD included with this kit. The files all start with “CSM” followed by “-C” for the coordinator, “-R” for the router, and “-E” for the end device. After the node type designation is the firmware version indicated by “vxxxxx” where xxxxx represents the version number. The modules are programmed using the ZProg.exe Windows utility program found the in the same Code Loads directory on the CD. The program can be run from the CD or copied to your computer. When ZProg starts, the following window will appear. Select the serial port to which the dev kit board is connected from the drop down menu and click on Connect. If the serial port does not show up in the list, check to make sure no other program is open using that port, such as ZBDemo. A Detecting Radio screen will appear and you will be prompted to cycle power to the dev kit. Simply unplug and the reconnect the power supply cord from the dev kit board. Once the module has been detected, the Detecting Radio window will close and the Connect button on the ZProg will change to disconnect. Click on the Select File button to choose the code load to use. If you know the complete path to the code load you want to use, you can type it in the Program Filename field. When you click on the Select File button the following screen will open.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 38 M-2405-0000 Rev. C- Select the desired file from the list of .bin files listed. Either double-click on the file name or click once on the filename and then click on the Open button. The file select window will close and the ZProg window will now have the file you selected in the Program Filename window as shown below. Click on the Program Device button to begin the programming process. The Progress bar will indicate the programming progress. When the ZProg has completed programming the module, it will verify the image in the module matches the selected program file. The following window will display during the verification

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 39 M-2405-0000 Rev. C- process. If the images agree, the verification window will close the success window will open. The module is now ready for use. ZProg can also verify the firmware that is in a module by comparing it to a program file selected. Once the file has been selected using the procedure above, click on the Verify Firmware button. The progress bar at the bottom of the ZProg screen will indicate the progress of the verification. If the image in the module matches the selected filename, the following success window will open. If the images do not match, a Verification Failed window will open with the message Images Differ across the top. 6.1 In Circuit Module Programming Due to the early nature of ZigBee and the number of profiles currently being developed by the ZigBee Alliance, it is advisable to provide a means for reprogramming the module in the end product. If the end product has a serial port, either RS-232 or USB, nothing further is required. If the end product does not have a serial port then one must be added. The diagrams below show how one can be easily and inexpensively added. There has been some information about over the air reprogramming of modules. While that will be the case in the future, the current size of the code and the memory resources available on the module do not allow that at this time.

ZMN2405/ZMN2405HP Dev Kit © 2007-2008 RFM Inc. 52 M-2405-0000 Rev. C- Appendix I Operating Scenario for ZMN2430A and ZMN2430HPA The ZMN2430A/HPA is used in a portable network application using Direct Sequence Spread Spectrum (DSSS) technology. The ZMN2430A/HPA is a ZigBee device utilizing IEEE 802.15.4 physical layer with propriety software to create network infrastructure that is decentralized and inexpensive, as each node need transmit only as far as the next node. Nodes act as repeaters to transmit data from nearby nodes to peers that are too far away to reach, resulting in a network that can span a large distance, especially over rough or difficult terrain. These products may be used as a portable, fixed or mobile device. Maximum Transmit Duty Cycle Each ZMN2430A/HPA can transmit a maximum of 4.2 ms per 50 ms. This is set by design and cannot be adjusted by the user. This equals 0.084 ms Therefore, our source-averaged transmit duty cycle becomes 0.0.84 Calculated Average Power The Power Threshold for ‘General Population’ portable designation without SAR testing is: (based on Oct 2005 TCB workshop PPT slide) (60 / FGHz) mW for distances < 2.5 cm For the 2.4 GHz frequency band, this results in a limit of 25 mW. Note that we use the more restrictive “General Population” limit in this case even though the individuals using this product will certainly be aware of its function and would qualify under the ‘occupational’ category. Given the maximum transmit duty cycle specified above, the average transmitted power of a ZMN2430HPA and a ZMN2430A remote can be calculated as: Maximum Pout = 135 mW (21.31 dBm nominal) Maximum Antenna Gain = 0 dBi (for portable use) Maximum Transmit Duty cycle (per above) = 0.084 Pave (Source-based average) = 0.135 * 0.084 = 11.3 mW Maximum Pout = 1 mW (-1.3 dBm nominal) Maximum Antenna Gain = 0 dBi (for portable use) integrated antenna Maximum Transmit Duty cycle (per above) = 0.084 Pave (Source-based average) = 0.001 * 0.084 = 0.084 mW Conclusion: The ZMN2430A and ZMN2430HPA meets the FCC MPE limits for a ‘Portable’ device operating in the ‘General Population’.
