GD8000 radio modem offers RS-232 interfacing wireless data transmission with the air rate of 8000bps. Radio modems with RS232 serial ports are used to connect a master station to one or more PLC based slave stations. GD8000 radio modems provide wireless data communication systems with compact size, portability, low power consumption and low cost solutions.
The data the radio modems communicate may be telemetry signals from GPS position, remote control signals, a transducer, computer communications, or a host of other digital messages.
