Driver Installation and Operation
The USB drivers obtainable from www.silabs.com/telegesissoftware will generate a virtual COM port
allowing easy access to the serial port of the embedded ETRX357. The ETRX357 development
board uses the same USB-to-serial device as the ETRX2USB and ETRX3USB products, so the
same USB drivers can be used. The development kit board and the USB stick use the same drivers
so you only need to install them once.
11.1 Windows 9x/XP/2k Driver Installation
Install the drivers before connecting the development kit using the provided USB cable. The driver
package should be unzipped into a local folder. When executing the file ‘TGvcpInstaller_x86.exe’ or
‘TGvcpInstaller_x64.exe’ an installer will guide you through the steps required for the driver
installation. Note that updates to the driver package may result in the various messages differing
from the screen-shots shown here.
The installer will first ask you to confirm the location for the files:
