RS-485 WIRELESS BRIDGE USER’S MANAUL REV. 02 3

Overview

The RS-485 wireless bridge is designed to be a transparent RS-485 cable replacement. The RS-485

Wireless Bridge has a five pin screw terminal connector that can be configured for either RS-485 two-

wire or four-wire communications mode. The RS-485 Wireless Bridge is available in three different

frequency and RF power options differing by frequency and RF output power options.

It is possible to mix and match wireless bridge products. The RS-485 Wireless Bridge will communicate

with the RS-485, RS-232, Analog and Digital I/O and USB wireless bridge products that share the same

radio configuration. By using an RS-485 Wireless Bridge at point A and a RS-232 Wireless Bridge at point

B, the wireless bridges can act as a RS-485 to RS-232 over-the-air converter.
