This allows connectivity to a computer's USB port. The ETRX3USB+8M and ETRX3USB-LRS+8M include an 8Mbit flash memory chip which can be accessed by the firmware in the EM357 ZigBee chip inside the USB stick. fo r The ETRX3USB-LRS and ETRX3USB-LRS+8M have an ETRX357-LRS module in place of the ETRX357 for longer range. The LRS variant has higher output power and better receiver sensitivity; consult the ETRX357 and ETRX357-LRS Product Manuals for the full details. m en de d The supplied Windows drivers create a virtual COM Port, so that the command line of the ETRX3 series module can be accessed via any terminal software application. When using Windows(R) the Telegesis Terminal application can be used as described in the ETRX357 Development Kit manual. 1.1 Supported Operating Systems R ec om Windows 98SE Windows XP/Vista/7 Windows 2000 Windows CE * MAC OS-9 MAC OS-X * Linux * N ot * drivers for these systems are available from Silicon Labs though most Linux distributions now include a suitable driver. The bridge chip is a CP2102 with Vendor ID 0x10C4 and Product ID 0x8293.

In particular the following certifications have been obtained: FCC compliance Class B Digital Device This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: N ew D 1. This device may not cause harmful interference, and 2. This device must accept any interference received, including interference that may cause undesired operation. * * * * m en de d fo r Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. om Modifications not expressly approved by the manufacturer could void the user's authority to operate the equipment under FCC rules. An FCC declaration of conformity is available separately from the Telegesis website Canada - Industry Canada (IC) R 5.2 ec The ETRX3USB and ETRX3USB+8M contain a modular radio transmitter with FCC ID S4GEM35XA. The ETRX3USB-LRS and ETRX3USB-LRS+8M contain a modular radio transmitter with FCC ID S4GEM35XB. N ot This Class B digital device complies with Canadian ICES-003. Cet appareil numerique de la classe B est conforme a la norme NMB-003 du Canada. 5.3 European Certification The ETRX3USB and ETRX3USB+8M as well as the ETRX3USB+LRS and ETRX3USB-LRS+8M limited to a maximum power level of 21.15mW e.i.r.p. (13.2dBm) have been tested and comply with the following standards: Radio: (c)2015 Silicon Labs EN300 328 v1.8.1 -7- ETRX3USB Product Manual (r4) ETRX3USB EMC: Safety: EN301 489-17 v2.2.1 EN60950-1:2006/A12:2011 es ig n An EC declaration of conformity is available separately from the Telegesis website. General N ew 5.4 D Important Note: In Europe the regulations for the 2.4GHz frequency band only permit.a maximum power spectral density of 10mW/MHz, which with a ZigBee spectrum equates to an e.i.r.p of 13dBm. The ETRX3USB cannot reach this level but the ETRX3USB-LRS can exceed it, so in the latter device the power out of the EM357 chip into the RF power amplifier should be limited to -11dBm. Refer to the ETRX357-LRS Product Manual for more details. For further technical information, including radio certification, see the corresponding ETRX3 series Module Product Manuals. fo r When ordering ETRX3USB sticks without printed branding on the case, you may be responsible for applying a marking appropriate to their geographical area of use, such as the CE marking. m en de d For more information on ZigBee compliance and the AT command interface firmware please refer to the latest AT command dictionary and the ETRX357 user guide. 6 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. om 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 1k resistor and increase the current consumption. ec 7 Firmware upgrades R 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 Product Manual. N ot Alternatively, access to the SIF programming interface is possible by opening the cover on the side of the ETRX3USB ZigBee USB stick. (c)2015 Silicon Labs -8- ETRX3USB Product Manual (r4) ETRX3USB 8 Driver Installation and Operation The drivers provided will generate a virtual COM port allowing easy access to the serial port of the embedded ETRX357. Windows XP/Vista/7 Driver Installation D 8.1 es ig n To read more about the ETRX357 wireless mesh networking module and its command line interface please read the corresponding documentation which can be found at http://www.silabs.com/telegesisdocuments. Figure 2: Found New Hardware Wizard R ec om m en de d fo r N ew The driver package downloadable from the Support Software centre page at http://www.silabs.com/telegesissoftware should be unzipped into a local folder. When executing the file `TgVCPInstaller.exe' prior to plugging in the ETRX3USB stick an installer will guide you through the steps required for the driver installation. N ot After insertion of the stick, Windows(R) may prompt that new hardware has been found. If you have run the `TgVCPInstaller.exe' Windows will be able to install the driver by automatically, 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 ETRX3USB has a unique serial number which requires the installation procedure to be repeated with every new ETRX3USB being attached to the computer, though the process is not obtrusive. This allows multiple ETRX3USB sticks to be used on the same computer at any one time. (c)2015 Silicon Labs -9- ETRX3USB Product Manual (r4) ETRX3USB m en de d fo r N ew D es ig n 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. om Figure 3. Device Manager N ot R ec Once the correct COM port has been selected, the Terminal software can be used to control the ETRX3USB stick as per the Development Kit Manual.

Telegesis Terminal Macintosh and Linux drivers fo r 8.2 m en de d A Virtual Com Port driver kit for Mac and Linux can be obtained by following the link on our website on the Support Software centre page. Recent versions of the Linux kernel have native support for Telegesis USB devices. The Silicon Laboratories CP2102 serial-to-USB bridge chip is configured with Vendor ID 0x10C4 and Product ID 0x8293, and the drivers must be written to recognise these identifiers. 9 Custom Firmware Development ec om If you intend to develop custom firmware to go onto the ETRX3USB you need to contact Silicon Labs to obtain access to their suite of development tools and their stack. The USB stick contains an ETRX357 module based on the Silicon Labs EM357 and a USB-to-serial bridge chip. The ETRX357 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. N ot R In order to download custom firmware onto the ETRX357, the Silicon Labs bootloader can be used or alternatively the ETRX3USB can be directly connected to the Silicon Labs InSight Adapter for programming and real time debugging.
