sETRX357-LRS Family The Telegesis sETRX357-LRS family of modules are low power 2.4GHz ZigBee modules with an added frontend module (SiGe SE2432L) containing both PA and LNA for highest possible link budget. Based on the Silicon Labs EM357 family of single chip ZigBee solutions the new long range modules offer three possible RF output configurations, namely an on board antenna, U.FL coaxial antenna connector or a RF pad.
sETRX357-LRS Family 1 Introduction This document describes the Telegesis small form factor sETRX357-LRS family of ZigBee long range modules which have been designed to be easily integrated into another device and to provide a fast, simple and low cost wireless mesh networking interface. The Telegesis sETRX3-LRS series modules are based on the Silicon Labs ZigBee compliant platform consisting of the EM357 single chip family combined with the ZigBee PRO compliant EmberZNet meshing stack.
sETRX357-LRS Family 2 Product Approvals The sETRX357-LRS family has been designed to meet all national regulations for world-wide use. In particular the following certifications have been obtained: 2.1 FCC Approvals The Telegesis sETRX357-LRS and sETRX357-LRS8 modules with integrated Antenna as well as the sETRX357HR-LRS and sETRX357HR-LRS8 modules including the antennas listed in table 2 and the power levels listed in section 10.
sETRX357-LRS Family separation distance of 2.6cm is maintained between the radiator (antenna) and all persons at all times. 2.1.1 FCC Labelling Requirements When integrating the sETRX357-LRS, sETRX357HR-LRS, sETRX357-LRS8 or sETRX357HRLRS8 modules into a product it 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: S4GSEM357L) as well as the notice above.
sETRX357-LRS Family OEM Responsibilities The sETRX357-LRS and sETRX357HR-LRS families of modules have been certified for integration into products only by OEM integrators under the following conditions: 1. The antenna(s) must be installed such that a minimum separation distance of 2.6cm is maintained between the radiator (antenna) and all persons at all times. 2. The transmitter module must not be co-located or operating in conjunction with any other antenna or transmitter.

sETRX357-LRS Family 5 Firmware Description By default, the modules will be pre-loaded with a standalone bootloader which supports over-theair bootloading as well as serial bootloading of new firmware. In order to enter the standalone bootloader using a hardware trigger pull PA5 to ground and power-cycle or reset the module. To avoid entering the standalone bootloader unintentionally make sure not to pull this pin down during boot-up unless the resistance to ground is >10kΩ. (A pull-up is not required).
sETRX357-LRS Family 5.1 Token Settings The sETRX357-LRS series modules’ manufacturing tokens will be pre-programmed with the settings shown in the table below.
sETRX357-LRS Family 5.4 Software Interface Using the default firmware the sETRX357-LRS 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 ATCommands, please refer to the AT command dictionary document which corresponds to the firmware revision you intend to use. In addition to the command dictionary there are user guides explaining the features of the firmware in more detail.

sETRX357-LRS Family 10.2 Power Settings for Regulatory Compliance Because of the high gain of the frontend module output power of up to 22dBm can be achieved When the antenna gain is included the output power of the sETRX357-LRS transceivers needs to be reduced for regulatory compliance. The following tables list the maximum permitted power setting for the antenna types listed in Table 2.
sETRX357-LRS Family 11 Physical Dimensions Figure 5. ETRX3 Physical Dimensions For ideal RF performance when using the on-board antenna, the antenna should stick out from the carrier PCB. There should be no components, tracks or copper planes in the “keep-out” area which should be as large as possible. When using the U.FL RF connector or the Rf pad the “keepout” area does not have to be kept.

sETRX357-LRS Family 14 Recommended Footprint In order to surface mount a sETRX357-LRS series module, we recommend that you use pads which are 0.86mm wide and 1.5mm high. Unless using the “HR” or “AP” variants it should be insured that the antenna area is not on top of the carrier PCB For best RF performance it is required to provide good ground connections to the ground pads of the module.
sETRX357-LRS Family Although the undersides of the sETRX357-LRS series modules are fully coated, no exposed copper, such as through-hole vias, planes or tracks on your board component layer, should be located below the sETRX357-LRS series module in order to avoid ‘shorts’. All sETRX357-LRS series modules use a multilayer PCB containing an inner RF shielding ground plane, therefore there is no need to have an additional copper plane directly under the sETRX357-LRS series module. tbd Figure 95.
sETRX357-LRS Family 14.1 Recommended Placement tbd Figure 10. Typical placement tbd Figure 11. How to not place the Module tbd Figure 12.
sETRX357-LRS Family 14.2 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 6shows the reference carrier board which was used during testing by Telegesis. Figure 6: Reference Board Finally to provide a good reference ground to the on board antenna, the carrier board should have a ground plane spanning no less than 40 x 40mm.
