PC-Based I/O Overview

This document shows examples of system architecture for PC-based I/O control systems and lists Opto 22 products that work together for PC-based control. System examples include:

- Ethernet systems using SoftPAC, a software-based programmable automation controller programmed with PAC Control
- Ethernet systems using the OptoMMP protocol
- Direct control of I/O using no I/O processor (no brain)
- Serial control using a brain and the mistic or Optomux protocol
- High-speed control using the Pamux protocol

RS232 to RS422/485 Converter Data Sheet

The AC7 is a stand-alone adapter card that converts RS-232 serial communication to RS-422 serial communication, which is directly compatible with the  Optomux brain boards .

AC7A - AC7B Users Guide

This document gives instructions for installing the AC7A/B adapter card in an Optomux network in 4-wire RS-422/485 mode with a PC and how to communicate with equipment other Optomux.
