The transceiver module operates within the frequency band 902 MHz to 928 MHz according to FCC Part 15, Section 15.249. The transmission and receive frequency is set to 916.5 MHz. FSK modulation is done with 19 kHz deviation. The transceiver module TRX916 provides extensive hardware support for packet handling, data buffering, burst transmission link quality and wake on radio. The main operation parameters and the 64-byte transmit/receive FIFOs of the transceiver module can be controlled via an SPI interface. A system consists of two transceiver modules integrated in an appropriate terminal equipment, which can be used in each case as transmitters and/or receivers.

UHF Transceiver Module TRX916 User Manual V 1.0 eQ-3 Limited Page : 10 of 12 15 Software / Register Settings After start up (connection to power supply) the transceiver module must be programmed with the necessary main operating parameters. Configuration is done using the SPI interface. To achieve the technical data and to ensure the FCC requirements according FCC Part 15, section 15.249 the register settings must be done after start up. The necessary software parameter (register settings) are available on request from eQ-3 Limited after conclusion of a non-disclosure agreement. 16 Notes Of Design • Please follow the condition written in this specification. • This product should not be stressed when installed. • Please keep this module away from heat. • The supply voltage should not be exceeding or reverse and should not carry noise and spikes. • Please keep this product away from other high frequency circuits. • Please follow the condition written in this specification about the control signals of the module. 17 FCC Information The RF Transceiver Module eQ-3 TRX916 meets the requirements for modular transmitter approval as described in FCC Public Notice DA00-1407. To fulfill the requirements of the FCC rules, the OEM (Original Equipment Manufactor) must pay attention to the following items. 17.1 FCC ID The FCC Equipment Authorization for this RF Transceiver Module is identified by FCC ID: RNT-TRX916 and issued to the grantee eQ-3 Limited, Hong Kong.
