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 .
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.
