RV-M21 Tech Series Enclosure
The Raveon M21 Tech Series radios will work as base station, repeater or GPS transponder, redundant power supply, and GPS transponder receiver which interoperates with our GPS radio modems. Tech Series Modular Smart Radios Modems allow for more control over the system. RV-M21 are long-range narrow-band UHF or VHF data radio modems. RF output at 5W or less is available in the RV-M21.
It has a rugged power connector and a Myriad of IO interface options: RS-232, RS485, RS-422, USB, GPIO, FIO…
Features include:
- Myriad of IO features and GPS tracking capability.
- Automatic RF output switching.
- Dual GPS RF connections, enabling hot-standby of GPS-enabled radio modules.
- Redundant radio module, which can be configured in reserve-standby mode (backup radio is powered down until it is needed)
- hot-standby mode (backup radio is always powered)
