Product Description

The GDW296 is a half duplex, transparent wireless modem with over the air rate 9600bps. It provides an RS232 compatible path without the user needing to format, code, detect or otherwise worry about modifying his existing data stream or providing extra control lines.

RS232 Interface Wireless Modem

Wireless transceiver modules of GDW296 support common point-to-point and point-to-multipoint topologies. In long-range applications, wireless communication links offset the expenses and challenges inherent in running long cables.

These modems excel in performance, and will work reliably in the presence of interfering signals and strong nearby carriers.
