The GDW2160 is an RS-232 wireless modem with the air rate 16000bps designed for remote communication operating in a transparent way. It provides a maximum line of sight (LOS) transmission distance of 50 kilometers.
Capable of high-speed communications with serial devices, the GDW2160 can communicate with either transparent broadcast mode or a controlled addressed private mode. The user interface data rate, addresses and operating parameters can all be easily read or re-programmed via the serial port with a PC-based software.
