This allows connectivity to a computer’s USB port. The supplied drivers create a virtual COM Port, so that the command line of the ETRX357 can be accessed via any terminal software application. When using Windows® the Telegesis Terminal application can be used as described in the ETRX357 Development Kit manual. 1.1 • • • • • • • • Supported Operating Systems Windows 98SE Windows XP Windows Vista Windows 7 Windows CE * MAC OS-9 MAC OS-X * Linux * * Drivers for these systems are available from Silicon Labs. The bridge chip is a CP2102 with Vendor ID 0x10C4 and Product ID 0x8293. 2 Absolute Maximum Ratings Parameter Min. Max.

If you purchase ETRX357USB sticks without printed markings on the case, you may be responsible for applying a marking appropriate to their geographical area of use, such as the FCC certification. For more information on ZigBee® compliance and the AT command interface firmware please refer to the latest AT command dictionary and the ETRX3 series user guide. 1 2 During USB suspend the current will drop by 25.6mA in all modes. Please note that the power consumption in various power modes is firmware and usage dependent. ©2011 Telegesis (UK) Ltd -4- ETRX357USB Product Manual (Rev 1.00) ETRX357USB AND ETRX357USB-LRS 5 ETRX357 I/O Connectivity The I/Os of the built-in ETRX357 are connected as follows: • • • PA6 is connected to the LED (drive PA6 low to sink LED current). PB3 is the CTS input for the ETRX357. Make sure PB3 is never defined as an output. PB4 is the RTS input for the ETRX357. Important Note: The lines for hardware handshaking are connected, so even when not using hardware handshaking PB3 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. 6 Firmware upgrades The firmware which is loaded onto the embedded ETRX357 Module can be upgraded over the air or via the virtual COM port as described in the ETRX357 Development Kit manual. Alternatively, access to the SIF programming interface is possible by opening the cover on the side of the ETRX357USB ZigBee USB stick. ©2011 Telegesis (UK) Ltd -5- ETRX357USB Product Manual (Rev 1.00) ETRX357USB AND ETRX357USB-LRS 7 Driver Installation and Operation The drivers provided will generate a virtual COM port allowing easy access to the serial port of the embedded ETRX357. To read more about the ETRX357-LRS 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 XP/Vista/7 Driver Installation The driver package downloadable from the Support
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 ETRX357USB stick an installer will guide you through the steps required for the driver installation. Figure 1: Found New Hardware Wizard After insertion of the USB stick, Windows® may prompt that new hardware has been found. If you have run the ‘TgVCPInstaller.exe’ Windows will be able to install the driverautomatically, but if you have not run ‘TgVCPInstaller.exe’ you will have to manually point to the directory into which you have unzipped the driver. Please note that each ETRX357USB has a unique serial number which requires the installation procedure to be repeated with every new ETRX357USB being attached to the computer, though the process is not obtrusive. This allows multiple ETRX357USB 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 open 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. ©2011 Telegesis (UK) Ltd -6- ETRX357USB Product Manual (Rev 1.00) ETRX357USB AND ETRX357USB-LRS Figure 2. Device Manager Once the correct COM port has been selected, the Terminal software can be used to control the ETRX357USB stick as per the Development Kit Manual. Figure 3. Telegesis Terminal ©2011 Telegesis (UK) Ltd -7- ETRX357USB Product Manual (Rev 1.00) ETRX357USB AND ETRX357USB-LRS 7.2 Macintosh and Linux drivers A Virtual Com Port driver kit for Mac and Linux can be obtained by following the link on our website on the Support
Software download page. 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 with no input whatsoever from Telegesis.) 8 Custom Firmware Development If you intend to develop custom firmware to go onto the ETRX357USB the InSight toolchain from Ember Corporation is required. This is obtainable from Ember as part of their development kit – www.ember.com The USB stick contains an ETRX357-LRS module based on the Ember EM357 and a USB-to-serial bridge chip. The ETRX357-LRS 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 EM357 pad PA6. In order to download custom firmware onto the ETRX357, the Ember bootloader can be used or alternatively the ETRX357USB can be directly connected to the Ember InSight Adapter3 for programming and real time debugging.

There is no “blank” version of the ETRX357 Module available. All Modules carry both the Ember Stack and the Telegesis AT style Command Layer. Where customers wish to add their own firmware they can erase and write it to the flash memory of the Ember EM35x. Please contact Telegesis if you require additional AT style commands or specific integration assistance. Table 11.
