  • Page 4 It has been designed to be integrated into any device without the need for RF experience and expertise. The form factor of the ETRX2-PA is identical to the ETRX2, so either module can be used depending on the range requirements of the particular application.

  • Page 5: Introduction

    The configurable functionality often allows the ETRX2-PA wireless meshing module to be used without an additional host microcontroller saving even more integration time and costs. In addition to the Telegesis AT Commandset, the ETRX2-PA can be used in with custom build firmware or the Ember EZSP over UART protocol interface...

  • Page 6: Product Approvals

    (right-angle) Table 1: Approved Antennae While the applicant for a device into which the ETRX2-PA or ETRX2HR-PA (with an antenna listed in Table 1) is installed is not required to obtain a new authorization for the module, this does not preclude the possibility that some other form of authorization or testing may be required for the end product.

  • Page 7: Fcc Labelling Requirements

    2.1.1 FCC Labelling Requirements When integrating the ETRX2-PA or ETRX2HR-PA into a product if must be ensured that the FCC labelling requirements are met. This includes a clearly visible label on the outside of the finished product specifying the Telegesis FCC identifier (FCC ID: T7VEM250B) as well as the notice above.

  • Page 8: Declarations Of Conformity

    Some level of interoperability with 3rd party ZigBee PRO compliant nodes Please note that the R2xx and to some extent the Telegesis AT-Command line interpreter are based on a private application profile and use the Ember meshing and self-healing stack, so interoperability with wireless mesh networking solutions from other manufacturers is unlikely when using this default firmware.

  • Page 9: Module Pinout

    The table below gives details about the 38 module pin signals for direct SMD soldering of the ETRX2-PA to the application board. The pin numbers shown in brackets () are the related pins of the EM250. In order to use the ETRX2-PA as a plug-in solution a Harwin 1.27mm pitch connector can be fitted on the bottom of the ETRX2-PA (Harwin part number M50-3601042).

  • Page 12: Hardware Interface

    I/O. UART The AT style command interpreter can be accessed via the TXD and RXD pins. The ETRX2-PA can buffer up to 128 bytes of incoming data in a software FIFO buffer and uses XON/XOFF or hardware flow control.

  • Page 13: Firmware Description

    SPI and I2C buses are not supported by the current firmware release, but can be used with custom firmware. As a third option as opposed to using the Telegesis AT command interface or developing custom firmware, the Ember EZSP UART interface can be provided to allow ZigBee® application development using a host controller driven binary protocol.

  • Page 14: Software Interface

    ETRX2PA 6.2 Software Interface Using the default firmware the ETRX2-PA is controlled using a simple AT-style command interface and (mostly) non-volatile S-Registers. In order to get a full listing of all the available AT- Commands, please refer to the AT command dictionary document which corresponds to the firmware revision you intend to use.

  • Page 15: Absolute Maximum Ratings

    8 Operating Conditions Please Note: The firmware of the ETRX2 series and the ETRX2-PA series is identical, therefore when talking about power settings in the following chapters, the actual output power out of the on board EM250 is described, rather than the power amplified output out of the module.

    You must also ensure that there are no exposed pads or vias on your layout which may contact with the pads (for the optional connector), or vias on the bottom surface of the ETRX2-PA module. If the module is to be soldered by hand for prototyping we recommend that you increase the height of the pads to allow easier access.

  • Page 26: Example Carrier Board

    Since the RF performance of the module with the on board antenna is strongly dependent on the proper location of the module on its carrier board, Figure 10 shows the reference carrier board which was used during testing by Telegesis. Figure 10: Reference Board For best performance it is recommended to locate the antenna towards the corner of the carrier board and to respect the recommended keep-out areas as described in section 12.
