Product Description

GDM212 is an 1200bps air rate Radio modem with RS232 serial port. The radio unit can operate as a transparent radio link, essentially replacing a wire with classic RS-232 based protocol. It is designed for long rang telemetry, SCADA and Remote control application under different weather conditions.

0-1200pbs Radio Modem

Depending on these radio modems, the range of RS-232 communication can be extended up to 20 miles or more in pure line-of-sight conditions. GDM212 has 12V or 24V operating voltage levels to chose from and low power consumption, it is extremely well suited for outdoor use.
