ETRX357-LR Product Manual
Contents
1. The main building blocks of the ETRX351 LR and ETRX357 LR are the single chip EM351 and EM357 from Ember a Power Amplifier as well as a Low Noise Amplifier a 24MHz reference crystal and RF front end circuitry optimized for best RF performance The modules are available with on board antenna or alternatively a U FL connector for attaching external antennae Modules with the UEL connector are identified by the HR suffix The LNA and RF power amplifier of the LR devices improve the output power by 10dB and the sensitivity by 5dB which will increase the range by approximately 600 relative to the standard devices where local regulations permit the use of the maximum output power The integrated antenna is an Antenova Rufa and details of the radiation pattern etc are available from the Antenova website 5 Module Chip Flash RAM ETRX351 LR EM351 128kB 12kB ETRX351HR LR EM351 128kB 12kB ETRX357 LR EM357 192kB 12kB ETRX357HR LR EM357 192kB 12kB Table 1 Memories The ETRX351 LR and ETRX357 LR are used for ZigBee www zigbee orq applications If you wish to create your own custom firmware and not use the pre loaded Telegesis AT Command interface you will need the InSight toolchain consisting of InSight Desktop together with a comprehensive integrated development environment IDE and C language compiler toolchain from Ember The Ember development environment is not suitable for an 802 15 4 only application that does not use the2.

3. 2 5 The ZigBee Protocol The ZigBee Protocol is a set of standards for wireless connectivity for use between any devices over short to medium distances The specification was originally ratified in December 2004 paving the way for companies to start making low power networks a reality ZigBee uses an IEEE 802 15 4 radio specification running on the 2 4GHz band plus three additional layers for networking security and applications What makes the specification unique is its use of a mesh network architecture which in bucket chain style passes data from one node to the next until it lands at its destination The network is self healing and adapts its routing as link quality changes or nodes move Furthermore nodes can be defined as End Devices which do not act as routers but can therefore be put into a low power sleep state The enhanced version of the ZigBee standard or ZigBee 2006 was released in December 2006 adding new features and improvements to the only global wireless communication standard enabling the development of easily deployable low cost low power monitoring and control products for homes commercial buildings and industrial plant monitoring In 2007 the ZigBee Alliance introduced the PRO featureset which offers advantages over earlier versions including Truly self healing mesh networking Messages can now travel up to 30 hops Source Routing for improved point to multipoint message transmission Improved security i
