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.
