1 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.
When using Windows® the Telegesis Terminal application can be used as described in the
ETRX357 Development Kit manual.

chip with SPI interface to the EM357. The pin connections to the EM357 are shown in Figure 1.

The Telegesis R3xx firmware does not have any capability of driving the SPI connection to the
memory chip. Users will have to write or commission custom firmware to make use of this external
memory.
