OEM Responsibilities

The ETRX358x-LRS and ETRX358x-LRS families of module 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 0.75cm is

maintained between the radiator (antenna) and all persons at all times.

2. The transmitter module must not be c o-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.).

IMPORT ANT NOTE: In the event that these conditions can not be met (for certain configurations or co-location with another transmitter), then Industr y 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 ETRX358x-LRS and ETRX358xHR-LRS family modules are labelled with its own IC Certification Number. If the IC Certification Number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label ref erring 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-EM358L” or “Contains IC: 8735A-EM358L”

The OEM of the ETRX358x-LRS and ETRX358xHR-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.

ETRX358x-LRS and ETRX358xHR-LRS

2.3 European Certification

The ETRX358x and ETRX358xHR families are with the maximum power settings defined in section 10.2 of this document compliant to the following standards:

• Radio: EN 300 328:V1.9.1

• Safety: EN 60950-1:2006 / A12:2011

All tests have been conducted with the antennae listed in Table 2. If the ETRX358x-LRS and ETRX358xHR-LRS families of modules are incorporated into an OEM

product, the OEM product manufacturer must ensure compliance of the final product to the European Harmonised EMC, and low voltage/safety standards. A Declaration of Conformity must be issued for each of these standards and kept on file as described in the R&TTE Directive. The final product must not exceed the specified power ratings, antenna specifications and installation requirements as specified in this user manual. If any of these specifications are exceeded in the final product then a submission must be made to a notified body for compliance testing to all of the required standards.

The ‘CE’ marking must be applied to a visible location on any OEM product. For more information please refer to http://ec.europa.eu/enterprise/faq/ce-mark.htm

. Customers assume full responsibility for learning and meeting the required guidelines f or each country in their distribution market.

2.4 Declarations of Conformity

Telegesis (UK) Ltd has issued Declarations of Conformity for all ETRX3 series ZigBee RF Modules, which cover Radio Emissions and Safety. These documents will be available f rom our website or on request

2.5 IEEE 802.15.4

IEEE 802.15.4 is a standard for low data rate, wireless networks (raw bit-rate within a radio packet of 250kbps @2.4GHz) which focuses on low cost, low duty cycle, long primary battery life applications as well as mains-powered applications. It is the basis for the open ZigBee Protocol.

ETRX358x-LRS and ETRX358xHR-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. 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 feature-set which offers advantages over earlier feature-sets, 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 including Trust-Centre link keys

• New message types and options

Notes:

{1} When the alternate GPIO function is selec ted, TX_ACTIVE becomes an output that indicat es that

the EM35x radio transceiver is in trans mit mode. PC5 must not be us ed i n t his mode as it is needed internally as TX_ACTIVE to control the external RF front end and power amplifier. PB0 is not available to the user.

{2} The serial UART connec tions TXD, RX D, CTS and RTS are P B1, PB2, PB3 an d PB4 respectivel y.

The device sends its data on TXD and receives on RXD. {3} If PA5 is driven low at power-up or reset the module will boot up in the bootloader {4} PA6, PA7, PB6, PB7 and PC0 can drive high current (see section 8) {5} nRESET is level-sens itive, not edge-sens itive. The module is held in th e reset state while nRE SET

is low. This signal has a 30kΩ Pull-Up. {6} ETRX3588, ETRX3586, ETRX 3582 and ETRX3588HR, ETRX3586HR, ETRX3582HR variants only

Important Note: The ETRX358x series and the ET RX358x-LRS series of modules are footprint compatible, but on the ETRX358x-LRS series pins PB0 and PC5 of the EM358x are used internally to control the front-end module and are not available to the user. PC5 is still available on Pad2, but it is configured as TX_ACTIVE signal and cannot be used as a general purpose GPIO.
