Abstract
The present invention relates to a system in accordance with which switching signal produced in the one piece of equipment is transmitted to another piece of equipment through a digital/analog converter. The transmitted analog signal is further converted into a digital signal by means of an analog/digital converter in the above equipment so as to carry out the switching control of the circuits and so on in the equipment by means of the signal converted into digital form. This is done so that the transmission of the switching signal between a plural number of pieces of equipment comparatively close to each other or under the condition where mixture of noise hardly cannot readily take place might be realized by means of a very small number of wires.
