PURPOSE:To prevent adverse effects such as the reduction of responsiveness to other terminals using a transmission line and quickly and smoothly perform dimming by making the transmission line for a dimming monitoring terminal a separate system from other transmission lines. CONSTITUTION:When a certain dimming level is set by a continuous dimming level setting means 55, the dimming data corresponding to the dimming level are transmitted to a master machine 1 from a continuous dimming monitoring terminal 11 via the transmission line 9 of a separate system. The master machine 1 generates and transmits the dimming control data of a lighting load 13 to a control terminal 5 based on the dimming data and sets the dimming level of a lighting load 13. Transmission lines connected with other terminals are not occupied by the operation of the continuous dimming level setting means 55, and the transmission line of the continuous dimming monitoring terminal 11 is not occupied by other terminals. The quick dimming operation can be performed without giving adverse effects such as the reduction of the response speed to other terminals. |
