This allows connectivity to a computer’s USB port. The supplied drivers create a virtual COM Port, so that the command line of the ETRX2 can be accessed via any terminal software application. When using Windows® 9x/XP/2000 the Telegesis Terminal application can be used as described in the Development Kit manual. 1.1 • • • • • • Supported Operating Systems Windows 98SE Windows XP Windows 2000 MAC OS-9 MAC OS-X Linux 2 Absolute Maximum Ratings Parameter Min.

Please note that the power consumption in various power modes is firmware and usage dependent. ©2009 Telegesis (UK) Ltd -4- ETRX2USB Product Manual (Rev 1.04) ETRX2USB 5 ETRX2 I/O Connectivity The I/Os of the built in ETRX2 are connected as follows: • • • I/O1 is connected to the LED (drive I/O1 low to sink LED). I/O2 is the CTS input for the ETRX2. Make sure I/O2 is never defined as an output. I/O4 is the RTS input for the ETRX2. Important Note: The lines for hardware handshaking are connected, so even when not using hardware handshaking I/O2 should never be defined as an output as this would drive against the incoming CTS signal via a 1kΩ resistor and increase the current consumption. Note that if you use the command “AT&F” on the USB stick, I/O1 will revert to being an input and the LED will not light up. To restore its function as a pilot light, use the command “ATS0E=00FA” (with R2xx firmware) or “ATS17=00FA” (with R3xx) followed by a reset. 6 Firmware upgrades The firmware which is loaded onto the embedded ETRX2 Module can be upgraded over the air or via the virtual COM port as described in the Development Kit manual. Alternatively, access to the SIF programming interface is possible by opening the cover on the side of the ETRX2USB ZigBee USB stick. ©2009 Telegesis (UK) Ltd -5- ETRX2USB Product Manual (Rev 1.04) ETRX2USB 7 Driver Installation and Operation The drivers provided will generate a virtual COM port allowing easy access to the serial port of the embedded ETRX2. To read more about the ETRX2 wireless mesh networking module and its command line interface please read the corresponding documentation which can be found at www.telegesis.com. 7.1 Windows 9x/XP/2k Driver Installation The driver package downloadable from the Support Æ Software download page of www.telegesis.com should be unzipped into a local folder. When executing the file ‘TgVCPInstaller.exe’ prior to plugging in the ETRX2USB stick an installer will guide you through the steps required for the driver installation. If prompted that the driver has not passed the Windows logo test simply press ‘Continue Anyway’. Figure 1: Found New Hardware Wizard After insertion of the stick, Windows® will prompt that new hardware has been found. If you have run the ‘TgVCPInstaller.exe’ Windows will be able to install the driver by automatically as shown in Figure 2. If you have not run ‘TgVCPInstaller.exe’ you will have to manually point to the directory into which you have unzipped the driver. ©2009 Telegesis (UK) Ltd -6- ETRX2USB Product Manual (Rev 1.04) ETRX2USB Figure 2: Install software Automatically Figure 3: Windows Logo Test Please note that each ETRX2USB has a unique serial number which requires the installation procedure to be repeated with every new ETRX2USB being attached to the computer. This allows multiple ETRX2USB sticks to be used on the same computer at any one time. In order to find out the identity/number of the virtual com port the stick has been assigned to, please enter the Device Manager under the Windows Computer Management screen (see below) and click on the Ports (COM and LPT) section where you should find the new virtual COM port. By double clicking on the entry of the virtual COM port you can also change the number assigned to the virtual COM port when entering the advanced setup of the device. ©2009 Telegesis (UK) Ltd -7- ETRX2USB Product Manual (Rev 1.04) ETRX2USB Figure 4. Device Manager Once the correct COM port has been selected, the Terminal software can be used to control the ETRX2USB stick as per the Development Kit Manual. Figure 5.

In addition, one of our customers has written a Linux driver that will be included in the 2.6.25 kernel. It can be found at www.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/patches/. (Note that this is for information only, and this software was developed entirely outside Telegesis.) 8 Custom Firmware Development If you intend to develop custom firmware to go onto the ETRX2USB you need to contact Ember to obtain access to their suite of development tools and their stack. The USB stick contains an ETRX2 module based on the Ember EM250 and a USB-to-serial bridge chip. The ETRX2 communicates via its serial port, so the user’s firmware must use the UART of Serial Controller 1. The nRTS and nCTS lines are connected to the USB bridge chip. The LED on the USB stick is driven from ETRX2 pad I/O1, which is EM250 pin GPIO14. In order to download custom firmware onto the ETRX2, the Ember bootloader can be used or alternatively the ETRX2USB can be directly connected to the Ember InSight Adapter for programming and real time debugging. ©2009 Telegesis (UK) Ltd -9- ETRX2USB Product Manual (Rev 1.04) ETRX2USB 9 Ordering Information Ordering/Product Code * ETRX2 Description Module with: • • • ETRX2CF * Compact Flash Card • • • • ETRX2HR * * Type II Compact Flash Card Design AT Style Command Interpreter Integrated 2.4GHz Antenna Based on the ETRX2 Module with: • • • ETRX2USB AT Style Command Interpreter Integrated 2.4GHz Antenna No Harwin Connector AT Style Command Interpreter Hirose U.FL Antenna Connector No Harwin Connector USB Stick: • • • AT Style Command Interpreter Integrated 2.4GHz Antenna Based on the ETRX2 Notes: • • • Customers’ PO’s must state the Ordering/Product Code.
