UHF Narrowband Radio Transceiver Module The UHF FM narrowband compact radio module STD-602-429 is suitable for industrial remote control and telemetry applications operating in the 429 MHz band. This module which is targeted for use in Japan, has the Type Certification of Construction Design (Giteki mark) meaning no radio licence or registration is required to use it. The STD-602-429 has a simple serial interface and allows own communication protocol to be used. The RF Power, Data rate and Channel can be set through the use of dedicated serial commands. As required by the Japanese regulations, the carrier sensing function is also implemented and automatically executed. ■ Transparent interface for data input and output ■ Contains the Type Certification of Construction Design (Giteki mark) ■ Industrial remote control system General Parameter Specification Applicable standard Communication method Simplex, Half duplex Emission type Channel step RF bit rate Supply voltage Supply current Operating temperature Antenna Only to be used with the specified antennas Transmitterpart Parameter Specification RF output power Spurious emission Adjacent channel leakage power Receiverpart Parameter Specification Sensitivity (BER 1%) Adjacent channel selectivity Timing Parameter Specification Power on to TX / RX Interface Parameter Specification Data length: 8 bit, Parity: None, Stop bit: 1 Specifications are subject to change without prior notice CIRSDII DESIGN, INC. https://www.circuitdesign.jp STD-602-429 429 MHz ver. 1.0 Aug. 2025 Sales Division 7557-1 Hotaka, Azumino, Nagano 399-8303, Japan Tel:+81-(0)263-82-1024 Fax:+81-(0)263-82-1016
