ETRX2USB 1 Introduction The ETRX2USB wireless mesh networking USB Stick is effectively an RS232 to USB bridge connected to an ETRX2 ZigBee module. 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.
For further technical information, including radio certification, see the ETRX2 or ETRX2PA Module Product Manual. If you purchase ETRX2USB 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.
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’.

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.
Most Linux distributions now include suitable native drivers. 8 Custom Firmware Development If you intend to develop custom firmware to go onto the ETRX2USB you need to contact SiLabs to obtain access to their suite of development tools and their stack. The USB stick contains an ETRX2 module based on the SiLabs EM250 and a USB-to-serial bridge chip.
There is no “blank” version of the ETRX2 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 EM250.
