RS-422 Communications Overview

The E3X-CIF11 for RS-422 communications is a Communication Unit that
uses RS-422 to communicate with one or more Fiber Optical Sensors through
Fiber Amplifier Units, including monitoring incident light levels, writing param-
eters, and controlling operation. Using CompoWay/F messages allows read-
ing and writing parameters.
Sending CompoWay/F commands from the CompoWay/F master to the Com-
munication Unit, which functions as a CompoWay/F slave, allows reading and
writing of parameters for the connected Sensors using CompoWay/F mes-
sage communications.
