Product Description

The RS-485 standard expanded the number of devices and provided a way to create true multipoint communications. RS485 serial port Wireless Modem GDW424 is a transceiver for embedded wireless data with over the air rate 2400bps.

The Wireless modem has exceptional communication range, lower power, and low cost. Where transparent data communication is available, introducing a wireless link can be as simple as a plug-and-communicate scenario. A wireless RS-485 modem provides a cost effective way to connect master station to slave stations in SCADA systems.
