Product Description

The GDW2192 is a RS232 wireless modem with radio module and suitable interface circuit, power supply and connector. It has an air rate of 19200pbs and provides a complete RS232 radio modem interface.

The GDW2192 proprietary wireless RS-232 systems provide cost-effective advantages for RS232 and specialize in long range and low data throughput.

In order to overcome the interference encountered in harsh environments, the GDW2192 configures the transmission bit rate to a minimum of    250 pbs.  At the same time, the ability of the modem to resist noise and other interference is greatly improved.
