DISCLOSURE OF THE INVENTION 1 (Example 1) Hereinafter, an example of the present invention will be described with reference to the drawings. In FIG. 1, when the address data of the dimming unit 5 that controls the dimming of the illuminator is sequentially input from the dimming unit specifying means 14 to the address input of the RAM 21 which is a storage element, the data output indicates that the illumination The address data of the dimming unit 5 and the address data of the control unit 6 are stored in the RAM 21 in correspondence so that the address data of the control unit 6 which controls the devices is outputted sequentially. In addition, when the address data (channel number of 7 aeg) of the control unit 6 that controls the lighting equipment is input to the address manual, the RAM 22 outputs the data to adjust the current dimming level of the control unit 6. The light level data is what is output. In other words, this RAM2
2 stores the address data of the control unit 6 and the dimming level data at that time in correspondence with each other. Both RAs above
M21.22 constitutes a storage means. The address input, which is the input means of the RAM 21, can be switched between the address bus of the CPU 10 and the dimming unit specifying means 14 by the switching means 17, and the data output of the RAM 21 can be switched between the address bus of the CPU 10 and the dimming unit specifying means 14.
The switching means 18 can switch between the 10 data buses and the address input of the RAM 22. Also, RAM22
The address input is the address bus of CPU 10 and RA
It is possible to switch between the data output of the RAM 21 and the data output of the RAM 22 by the switching means 19.

It will be done. Then, the dimming level data at that time is outputted to the data output of the RAM 22. That is, the address data of the dimming unit 5 whose dimming level you want is R
By applying it to the address input of AM21, RAM2
1 is converted into address data (channel number of 7eg) for the control unit 6, and further converted into dimming level data by the RAM 22, and the dimming level data is outputted to the data output of the RAM 22.

o) and a second storage area whose address input is the address data of the control unit 6 that controls the illuminators and whose data output is the current dimming level of the address data. A RAM 23 is provided as a means. In other words, when the address data of the dimming unit 5 and the address data of the control unit 6 are input to the address input of this RAM 23, the address data of the control unit 6 and the VRS light level data are outputted from the data output. The address data of the dimming unit 5 and the address data of the control unit 6 are stored in correspondence with each other, and the address data of the control unit 6 and the dimming level data are stored in correspondence, respectively. Also, RAM2
The address input of No. 3 is connected to the address bus of the CPU10, the dimming unit specifying means 14 that controls the dimming output, and the latch circuit 24 that latches the address data of the control unit 6 outputted from the data output by the switching means 25. Switching is possible. In addition, the data output of RAM23 is
A switching means 26 enables switching between the U10 data bus, the latch circuit 24, and the dimming signal line that outputs dimming level data to the dimming unit 5.

When the connection function or the current dimming level changes, the address input and data output of the RAM 23 are connected to the address bus and data bus of the CPU 10 via the switching means 25 and 26. Then, the connection data or the current dimming level data is changed. At other times, the address data of the dimming unit 5 whose dimming level is desired is given to the address input of the RAM 23 from the dimming unit specifying means 14, and the address data of the control unit 6 at that time (channel number of 7 Aeg) is sent to the latch circuit. Latch at 24. Next, when the address data of the control unit 6 latched by the latch circuit constituting the conversion means is connected to the address input of the RAM 23 via the switching means 25, the dimming level data at that time is outputted to the data output. become. In this example, ffrJ
Compared to the embodiment, only one memory element, RAM 23, is required, and the number of components is reduced.
