1. A communications system comprising:
a control device;
a standard proxy input/output circuit configured to communicate with the control device and control a standard electric device; and
an extension proxy input/output circuit configured to communicate with the control device and control an extension electric device,
wherein the control device comprises:
a first clock terminal configured to allow a clock to be output therefrom;
a first input terminal configured to allow an input signal to be input thereto;
a first output terminal configured to allow an output signal to be output therefrom; and
a plurality of first selector terminals, each of the plurality of first selector terminals being configured to allow a selector signal to be output therefrom, the selector signal specifying a communication destination,
wherein each of the standard proxy input/output circuit and the extension proxy input/output circuit comprises:
a second clock terminal connected to the first clock terminal, the second clock terminal being configured to allow the clock to be input thereto;
a second output terminal connected to the first input terminal, the second output terminal being configured to allow the input signal input to be output therefrom;
a second input terminal connected to the first output terminal, the second input terminal being configured to allow the output signal to be input thereto; and
a second selector terminal connected to a corresponding one of the plurality of first selector terminals,
wherein the second selector terminal of the standard proxy input/output circuit and the second selector terminal of the extension proxy input/output circuit are connected to one of the plurality of first selector terminals and another of the plurality of first selector terminals, respectively,
wherein each of the standard proxy input/output circuit and the extension proxy input/output circuit is configured to communicate with the control device in synchronization with the clock in a case in which the selector signal is input to the second selector terminal,
wherein the control device and the standard proxy input/output circuit are provided on one substrate, and
wherein the control device and the extension proxy input/output circuit are connected to each other via an electric wire.
