PURPOSE:To make continous control possible only with the terminal side, by controlling the terminal equipment switch box at a step control time in the remote control unit of plural illumination dependent upon the main operation board. CONSTITUTION:N-channel components of the transmission signal constituted by the start signal, the address signal, and the control signal are generated from main operation board 11 cyclically; and when this transmision signal is transmitted through signal transmission line 13, the transmission signal agreeing with addresses set previously is discriminated by terminal equipments 15a-15d respectively, and a control mode corresponding to the control signal is set. Terminal equipments 15a- 15f are provided with switch box 18; and by switching the switch of box 18 to the LOCAL side, the variable resistance provided in box 18 is made variable to make continuous light adjustment possible. In the figure, 16a-16f are light adjusting equipments having thyristors, and 17a-17k are illumination loads. |
