ETRX3USB Product Manual (r4)

Introduction

The ETRX3USB ZigBee USB Stick is effectively an RS232 to USB bridge connected to an ETRX3

Series ZigBee module. 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.

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.

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.
