RMC – Rackmount Radio Interoperability Gateway

RIOS RMC – Rackmount Radio Interoperability Gateway

The RIOS RMC rackmount radio interoperability gateway connects to all types of two-way radios and push-to-talk devices for use with the RIOS Radio Interoperability System. The RIOS RMC provides interface for up to 32 radio entry points via 16 card slots for use with SyTech’s dual-channel interface cards. Simply unscrew, remove and swap the dual-channel card or insert new channel cards for increased scalability.

The backplane interface connects all types of radios and signaling devices via D-Sub 26 pin connectors, offering audio as well as control for select radio models. The RMC connects to the RIOS server computer via military standard MIL-C-26482 USB connector.
