Multiplex communication system

摘要

A reconfigurable serial loop multiplex communication system for communication of digital and analog status and control information between field terminal locations or to a central control location via a twisted pair line. Input modules in a first terminal station communicate signals received at their input to output modules having the same byte address in other terminal stations. At the central control locaton, signals from an input module may be readdressed for communication to output modules having a different byte address.
