2. Pin bit arrangement for external control terminals
Bit B0 B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 B11 B12 B13
Structure Light intensity bit (0 to FF) EXT WR ON1 CH ON2 OCP
A driver IC or an open collector outputs a signal to each terminal and the external
control signals are input to the product at CMOS level.
3. Optional external control cable is manufactured by CCS.
4. The product support the following types of external control.
- External and manual light intensity control selection
- Channel selection
- Light intensity settings
- Lighting ON/OFF control
- Overcurrent protection signal monitoring
External control
1. Connect the external control cable to the power supply.
(Also connect the lighting and any other devices.)
2. Input the desired control signal from the external control cable.
Note: External control connector terminals are 0 V when low (L) and 5 V when high (H).

1) External and manual light intensity control selection
Set bit B8 of the Dsub external control connector to
Low to set the product to external control mode.
Adjusting the light intensity from the front panel is
disabled in this mode. Set bit B8 to High to enable
light intensity from the front panel and disable
externally controlled light intensity.
B8 is active low (i.e., it is valid at 0 V)
2) Channel settings
Set the channel of the lighting that the product will
control. Use bit B11 on the Dsub external control
connector to specify the channel.
