Abstract

PURPOSE:To remarkably reduce the wirings input and output to the monitor unit and to reduce the cost, by switching the information indicating operating state fed from a plurality of units, in two stages, and transmitting them on the common line. CONSTITUTION:The information required to discriminate the operating state of a plurality of units 1 having various functions and constituting the communication unit passes through the electronic switching circuit 2 in each unit 1 and is fed to the item selection swtich 5 included in the monitor unit 4 via the common line 3, and the desired information is displayed on the meter by switching the switch 5. Further, the common line 3 only passes through the information for one unit, the unit selection swtich 6 in the unit 4 controls the circuit 2 and selects the required unit only. That is, a plurality of units 1 use the common line in time sharing manner by means of the switch 6, allowing to avoid simultaneous transmission of the information in other units.
