1 Introduction
This document gives an introduction on how to set up and operate the Telegesis ETRXn ZigBee
®
modules with firmware revisions R2xx. The examples in this document assume that you are using
the ETRXnDVKx Development Kit. However most of the features described can also be evaluated
using any custom hardware based on the ETRX1 or ETRX2 modules.
Towards the end of this document a number of possible application scenarios are listed in order to
show the versatility of the ETRXn modules.
Some of the details will vary from one firmware version to another; this guide was written when
R212 was current.
Do not use this guide if you are using R1xx firmware as the AT Command set is different. Please
check the Telegesis website
www.telegesis.com
regularly for updates.
2 Getting Started
The ETRXn sends and receives commands and data from its host computer through a UART as
ASCII strings. You can use your own application software, a tool such as HyperTerminal, or our
own Telegesis Terminal which is a free download from our website. To use it, first install .NET
Framework Version 1.1 Redistributable Package from Microsoft. This is currently available at
www.microsoft.com/downloads/details.aspx?familyid=262D25E3-F589-4842-8157-
034D1E7CF3A3&displaylang=en
Note that Version 2 or later is not sufficient as it supplements Version 1.1 but does not replace it.
Then download Telegesis Terminal from our website at
