ABSTRACT:
Remote control apparatus for controlling a number of pieces of equipment in which each unit includes a microprocessor which produces a first remote control signal on its data bus line and an interface circuit including a first latch circuit which receives the first remote control signal from the data bus line of the microprocessor and a second latch circuit which receives a second remote control signal on its input terminal and transfers the second remote control signal to the data bus line of the microprocessor. A common input/output terminal receives the first and second remote control signals and a switching means is connected between the common input/output terminal and a reference point such as ground and the switching means is controlled by the first remote control signal to pass it to the common input/output terminal.
