ETC ETRX2

ETRX2 – (ZigBee Technology)
Wireless Mesh Networking Module
The Telegesis ETRX2 module is a low power, 2.4GHz ISM band
transceiver, based upon the Ember EM250 single chip ZigBee /
IEEE802.15.4 solution and EmberZNet 2.xx meshing technology.
Designed for integration into any device without the need for RF
expertise the ETRX2 enables you to add powerful wireless networking
capability to your products and bring them quickly to market. The
comprehensive Telegesis AT command line interface allows for quick
integration without complex software engineering.


Two complementary development kits consisting of three
or five modules and a single development board with USB
connectivity and I/O breakouts.
AT-style software interface command dictionary can be
modified for high volume customers.
Custom software development available upon request.
EXAMPLE AT-STYLE COMMANDS
AT+BCAST
AT+UCAST:<address>
AT+EN
Sends a Broadcast
Sends a Unicast
Establish PAN network
Unlike many other module command layers the Telegesis ATStyle command set fully mirrors the functionality of the
EmberZNet mesh networking stack. With the ETRX2 module
there is therefore no requirement for any embedded firmware
expertise when engineering your mesh networking solution.
The ETRX2 is available in Power Amplified form.

ZigBee Technology ETRX2 based products
ETRX2-PA - Power Amplified Mesh Module
The Telegesis ETRX2-PA offers boosted output power whilst
being a drop in replacement for the standard ETRX2. Care was
taken to retain the low deep sleep current to make this module
ideally suited for battery operated end devices with the lowest
transmit current in its class.
ETRX2USB - USB Stick
ETRX2CF - CF Card
Based on the ETRX2 module, the
USB stick allows a PC/Server to
monitor and control devices in a
ZigBee network. The USB stick acts
as a virtual com port in Windows and
is controlled by the Telegesis ATStyle Commands.
Telegesis has used the ETRX2 Module to
provide a portable handheld unit able to
communicate with other modules in the
field.
Can be used in a PDA with a CF slot or in a
laptop computer with a PCMCIA/CF
adaptor. Contains an ETRX2 module and
therefore all the usual Telegesis AT-style
Commands available via a virtual com port.
EAP-E - Ethernet Access Point (below)
Router-E (above)
To accompany the Telegesis ETRX2 wireless mesh networking
modules the EAP-E Ethernet Access Points offer an easy way to
interact with remote ZigBee networks using Ethernet.
To accompany the Telegesis ETRX2 wireless mesh networking
modules the Router-E offers an easy way to extend the range of
ZigBee networks. Acts as a “router” which enables increased
distance between nodes in a ZigBee network.
Via Telnet, or a virtual COM port, the Telegesis AT-Command
interface - based on the EmberZNet meshing stack - can be
easily accessed by the application software. Custom firmware
development is also supported.
ETRX2DVKA - Development Kit (below)
This ETRX2 Development Kit provides genuine quick and easy,
out-of-the-box construction of a working mesh network. Using the
comprehensive AT-style Command Dictionary and the simple to
use Telegesis Terminal software package provided, it should take
less than half an hour to set up a three-way mesh network and to
begin detailed, in-depth assessment of the latest EmberZNet
meshing technology. Kit includes three ETRX2 modules.
ETRX2DVKA-Plus - upgraded Development Kit (above)
New Module Carrier Boards now have temperature and light
sensor plus SIF interface.
The Development Kit provides genuine quick and easy, out-ofthe-box evaluation and application development, based on the
Telegesis wireless meshing modules. Kit contents as per
