Radio Module RM1 Traffic Light Control and Radio Communication over short distances The RM1 radio cassette transmits voice and data on all common frequencies. It has been tuned to the special claims and requirements of the public transport. This is especially used when lower transmission power are sufficient. The RM1 can be used for short range radio or traffic light control. All parameters can be changed or updated by using the configuration software. Although the radio cassette has an integrated DC-DC converter with galvanic isolation. It requires very limited space. In addition, a robust aluminium housing protects the electronics, which guarantees high availability. The radio cassette is equipped with all important standard interfaces. Of course, Jöhl+Köferli AG supports its customers on site to integrate the RM1 into their vehicles. If the system is not installed in a rack, the RM1 radio module is a functionally compatible alternative. Jöhl+Köferli AG has developed and produced the RM1 radio cassette itself in Switzerland.
