Raveon’s RV-M22  Tech Series radio modems are industrial-grade, high-speed, data radios designed for telemetry, SCADA, AVL, wireless data, mobile-data and remote control applications. Designed by Raveon for long-range reliable communication using high-performance RF circuitry and filters, it is also feature-rich. For unsurpassed range on unlicensed frequencies, try the M22 Range Buster offered in the 2-watt FCC approved MURS band channels.

Raveon’s data radio transceivers increases data throughput in narrow-band wireless systems. Included in each unit, are advanced networking, error correction, and diagnostics. The M22S is the most efficient and economical data radio available. The Optional internal GPS ( GX option) enables the M22G to transmit its position, data, and status (voltage, speed, heading, temperature, I/O bits.) a pre-set intervals using either conventional carrier-sense methods or with efficient TDMA channel access. A GPS tracking system built with M22G transceivers, can track up to 20 radios with one-second updates or 200 with 10-second updated. The M22 is the fastest most efficient UHF AVL radio available. See details on its GPS tracking and TDMA abilities.

The M22 leads the industry in many areas including technology, features, and price. It is one of the smallest data radios in its class. It is one of the most rugged data radios made. It is one of the lowest power-consumption radios available. And its price will pleasantly surprise you. The radio modem modules inside the RV-M22 enclosure are available for OEM use.  The RV-M6 OEM module is the miniature 2 watts radio modem.

The Tech Series enclosure has a myriad of IO options:

  • RS-232
  • RS-422
  • RS-485
  • USB
  • GPIO  (digital, voltage reading, Switched DC out)
  • Analog
  • FIO    (digital IO)
