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. Integration into a wide range of applications is made easy using a simple AT style command interface and advanced hardware design.

The configurable functionality of the Telegesis AT Commandset often allows the sETRX357-LRS series of ZigBee modules to be used without an additional host microcontroller saving even more integration time and costs. In addition to the Telegesis AT Commandset, the sETRX357-LRS family can be used with custom-built firmware whilst representing an ideal platform for custom firmware development in conjunction with the Silicon Labs ZigBee development kits.

No RF experience or expertise is required to add this powerful wireless networking capability to your products. The sETRX357-LRS family offers fast integration opportunities and the shortest possible time to market for your product.

1.1 Hardware Description

The main building blocks of the sETRX357-LRS family are the single chip EM357 SoC from Silicon Labs, a SiGe SE2432L frontend module combining a Power Amplifier with 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, a U.FL connector or a RF pad for attaching external antennae. Modules with the U.FL connector are identified by the “HR” suffix, modules with the antenna pad by the “AP” suffix.

The integrated antenna is an Antenova Rufa, and details of the radiation pattern and further data are available from the Antenova website [5].

Table 1: Order Codes

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 up to 700% relative to unamplified devices with suitable propagation conditions (where local regulations permit the use of the maximum output power).

The sETRX357 family is used for ZigBee (www.zigbee.org) applications. In case it is desired to develop custom firmware instead of using the pre-loaded AT-Command interface, the Silicon Labs toolchain, consisting of Ember Desktop together with a comprehensive integrated development environment (IDE), is required.

The FCC requires the user to be notified that any changes or modifications made to this device that are not expressly approved by Telegesis (UK) Ltd. may void the user's authority to operate the equipment.

When using the sETRX357-LRS with approved antennae, it is required to prevent end-users from replacing them with non-approved ones. The antenna(s) must be installed such that a minimum

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. This exterior label can use wording such as “Contains Transmitter Module FCC ID: S4GSEM357L” or “Contains FCC ID:

S4GSEM357L” although any similar wording that expresses the same meaning may be used.

2.2 IC (Industry Canada) Approvals

The Telegesis sETRX357-LRS family with integrated Antenna as well as the sETRX357HR-LRS family have been approved by Industry Canada to operate with the antenna types listed in Table 2 with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device.

IC-ID: 8735A-SEM357L

• This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device.

• Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted for successful communication.

• This device has been designed to operate with the antennas listed in Table 2, and having a maximum gain of 2.1 dBi. Antennas not included in this list or having a gain greater than 2.1 dBi are strictly prohibited for use with this device. The required antenna impedance is 50 ohms.

French Statements

• Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain 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. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement.

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.

As long as the two conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.).

IMPORTANT NOTE: In the event that these conditions can not be met (for certain configurations or co-location with another transmitter), then Industry Canada certification is no longer considered valid and the IC Certification Number can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate Industry Canada authorization.

2.2.1 IC Labelling Requirements

The sETRX357-LRS and sETRX357HR-LRS modules are labelled with their own IC Certification Number. As the IC Certification Number is not visible when the module is installed inside another device, the outside of the device into which the module is installed must display a label referring to the enclosed module. In that case, the final end product must be labelled in a visible area with the following:

“Contains Transmitter Module IC: 8735A-SEM357L” or “Contains IC: 8735A-SEM357L”

The OEM of the sETRX357-LRS and sETRX357HR-LRS family modules must only use the approved antenna(s) listed above, which have been certified with this module.

The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module or change RF related parameters in the user’s manual of the end product.

Notes:

{1} When the alternate GPIO function is selected, TX_ACTIVE becomes an output that indicates that the

EM35x radio transceiver is in transmit mode. PC5 must be used in this mode as it is used internally

as TX_ACTIVE to control the external RF frontend. {2} The serial UART connections TXD, RXD, CTS and RTS are PB1, PB2, PB3 and PB4 respectively {3} When using the Telegesis AT Commandset, RTS/CTS handshaking is selectable in firmware. See

the AT Command Manual. {4} If PA5 is driven low at power-up or reset the module will boot up in the bootloader {5} PA6, PA7, PB6, PB7 and PC0 can source or sink high current (8mA) {6} nRESET is level-sensitive, not edge-sensitive. The module is held in the reset state while nRESET
