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.

SUGGESTED APPLICATIONS



DEVELOPMENT KITS



EXAMPLE AT-STYLE COMMANDS

AT+BCAST

AT+UCAST:<address>

AT+EN

Unlike many other module command layers the Telegesis AT-

Style 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.

AMR – Automatic Meter Reading.

Wireless Alarms and Security.

Home/Building Automation.

Wireless Sensor Networks.

M2M Industrial Controls.

Future ZigBee systems.

PC Peripherals.

IEEE 802.15.4 Systems.

Item Tracking.

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.

Sends a Broadcast

Sends a Unicast

Establish PAN network
