ETRX358x-LRS and ETRX358x-LRS The Telegesis ETRX358x-LRS and ETRX358xHR-LRS 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 latest Ember EM358x family of single chip ZigBee solutions the new long range modules are footprint compatible with the entire Telegesis ETRX3 family, thus representing a drop-in replacement for all applications where a high link budget is required.
ETRX358x-LRS and ETRX358x-LRS 1 Introduction This document describes the Telegesis ETRX358x-LRS and ETRX358xHR-LRS 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 ETRX3 series modules are based on the Silicon Labs ZigBee compliant platform consisting of the single chip family of EM358x SoCs combined with the ZigBee PRO compliant EmberZNet meshing stack.
ETRX358x-LRS and ETRX358x-LRS The LNA and RF power amplifier of the LRS devices improve the output power by 12dB and the sensitivity by 5dB which will increase the range by approximately 700% relative to the standard devices (where local regulations permit the use of the maximum output power). The ETRX358x and ETRX358xHR are used for ZigBee (www.zigbee.org) applications.
ETRX358x-LRS and ETRX358x-LRS 2 Product Approvals The ETRX358x-LRS and ETRX358xHR-LRS have 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 ETRX358x-LRS family with integrated Antenna as well as the ETRX358xHR-LRS family including the antennas listed in able 2 and the power levels listed in section 10.
ETRX358x-LRS and ETRX358x-LRS The antenna(s) must be installed such that a minimum separation distance of 20cm is maintained between the radiator (antenna) and all persons at all times. 2.1.1 FCC Labelling Requirements When integrating the ETRX358x-LRS or ETRX358xHR-LRS families into a product it must be ensured that the FCC labelling requirements are met.
ETRX358x-LRS and ETRX358x-LRS de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. • Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence.
ETRX358x-LRS and ETRX358x-LRS 2.3 European Certification The ETRX358x and ETRX358xHR families are at a maximum power level of 21.15mW e.i.r.p. (13.2dBm) compliant to the following standards: • • • Radio: EMC: Safety: EN 300 328:V1.8.1 EN 301 489-17:V2.2.1 EN 60950-1:2006/A12:2011 All tests have been conducted with the antennae listed in Table 2.
ETRX358x-LRS and ETRX358x-LRS 2.6 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.

ETRX358x-LRS and ETRX358x-LRS 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.
ETRX358x-LRS and ETRX358x-LRS 5.1 Token Settings The ETRX358x-LRS Series Modules’ manufacturing tokens will be pre-programmed with the settings shown in the table below.
ETRX358x-LRS and ETRX358x-LRS 5.4 Software Interface Using the default firmware the ETRX358x-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.

ETRX358x-LRS and ETRX358x-LRS 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 EM358x 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.

ETRX358x-LRS and ETRX358x-LRS 14 Recommended Footprint In order to surface mount an ETRX3 series module, we recommend that you use pads which are 1mm wide and 1.2mm high. Unless using the “HR” variants the “keep-out” zone shown in section 11 must be retained, and it must be ensured that this area is free of copper tracks and/or copper planes/layers. You must also ensure that there is no exposed copper on your layout which may contact with the underside of the ETRX3 series module.
ETRX358x-LRS and ETRX358x-LRS Although the undersides of the ETRX3 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 ETRX3 series module in order to avoid ‘shorts’. All ETRX3 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 ETRX3 series module. Figure 11.
ETRX358x-LRS and ETRX358x-LRS 14.1 Recommended Placement When placing the module please either locate the antenna in the corner as shown in Figure 12 so that the recommended antenna keepout zone is being followed, or add a no copper zone as indicated in Figure 14. Figure 12. Typical placement Figure 13.

ETRX358x-LRS and ETRX358x-LRS 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 17 shows the reference carrier board which was used during testing by Telegesis. Figure 17: 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 11.
