Abstract

The optical control system includes a control unit and an optical apparatus. The control unit includes an output switching section. The output switching section is switchable between a first state, in which the command signal from a command signal generation section is output via a first terminal of a first connector, and a second state, in which a switching signal for selecting the second control section, the voltage level of the switching signal being different from that of the command signal, is output from the first terminal. The control switching section of the optical apparatus selects the first control section in response to input of the command signal, and selects the second control section in response to the switching signal, which is input from the second terminal of the second connector.
