GD-192-232is a light-industrial grade serial RS232 RF radio modem with air rate of 19200bps.It allows reliable point to point, or point to multi-point communicationsbetween two or more devices at different locations.
The parameters of the RS232 radio modems can be configured through the serial portby using the downloadable configuration utility.With the configuration software each RS232 radio modem can be configured as customized data settings which includes baud rates, parity bit, stop bit and channel frequency.
GD-192-232 is an excellent choice for remote sensing and control applications.
