REMOTE SUPERVISORY CONTROL SYSTEM

摘要

A control terminal 32 includes an individual address setting section 12 for setting a unique individual address, and a simultaneous control address setting section 13 for setting a simultaneous control address common to the plurality of control terminals 32. A simultaneous control address is commonly assigned to the control terminals 32 to be subjected to group control. When an UP switch Sb or a DOWN switch Sc of an operation terminal 31b for group dimming purpose is pushed, a transfer signal including the simultaneous control address is transmitted to a signal line Ls from a transfer controller 30. The respective control terminals 32 substantially simultaneously receive the transfer signal, thereby changing the intensity of illumination loads.
