GD9600 radio modem can operate as a transparent radio link, essentially suitable for replacing a wire with classic RS-232 based protocol. It supports various network topologies, from a simple long-range point-to-point link to point-to-multipoint systems or even multipoint-to-multipoint networks.
It is provides a compact and flexible solution for many different long-range applications. GD9600 is a data radio unit with over-the-air data rate of 9600bps where RS232 serial interface is used. Due to the high transmitting power, connection distances over tens of kilometers can be easily covered
