CI-132

Overview

The Industio CI-132 series of multiport serial boards is designed for RS-422/485 industrial communication. It supports two independent RS-422 or RS-485 ports, with each port able to control up to 64 devices in a multidrop environment.

ADDC™ (Automatic Data Direction Control) intelligence is built into each CI-132 board to eliminate the need for software interference. Hence, applications can easily manage the half-duplex RS-485 port data transmitting and receiving without the need for extra code. In addition, on-chip hardware flow control, built-in termination resistors, and optical isolation and surge protection options are able to deliver high reliability for harsh industrial applications.
