Description

Synchronous signal input.

When the slave mode is selected, connect these pins to the master

I side SYNC OUT 1, and 2 pins.

When the master mode is selected, the input level of these pins are ignored.

Connect these pins to VDD or L-GND at the master mode.

O Dimming pulse output.

Connect this pin to the slave side DIM IN pin.

Synchronous signal output.

O Connect these pins to the slave side SYNC IN 1, and 2 pins.
