Abstract

Abstract A panel system whereby an attendant may control a plurality of utilization circuits including a control panel manually adjustable to a plurality of modes each representative of a particular utilization circuit to be controlled and the desired status thereof. The control panel is connected to a multiplexer for producing a multiplexed signal including in assigned time frames digital codes representative of said control panel mode. A plurality of demultiplexing means are each connected with at least a portion of said utilization circuits and said multiplexing means for receiving said multiplexed signal, and upon detecting a digital code assigned to one of its utilization circuits, placing said utilization circuit in the status indicated by said control panel.
