Product Description

RS485 Wireless Date ModemGrandComm's GD49K6 is a 9600bps air rate radio modem with RS485 port for communicating with the devices they are connected.

These radio modems are especially well suited for packet radio communications like SCADA systems. With GD49K6 radio modems, you can transfer files, monitor remote operations, send control command and use numerous other packet radio applications. . They can receive the radio waves without any loss of data and saves huge wiring expense and maintenance costs.

Each radio modem can store 60 channels, and multiple radio pairs can operate at the same location without interference.
