Opto isolator question

[Voicecoil]

I've never used this board but going off normal terminology I would guess that you need to connect your outputs to the U1, U2, U3, U4 terminals and the ground to the G terminals (you may need to common these up if your lights aren't). I also suspect that the 4 jumpers link the input side ground to the output G on a channel by channel basis, so pull thes for proper isolation. And check that your lights don't require too much current, opto's do have a finite current rating.

which breakout board do you have ?
a photo or link will help to find out what type of input the BOB has

going by your photo of the opto-isolator board it looks like the opto-isolators photo transistor collector is connected to the output terminal (U1, U2 ,U3 ,U4 ) via a resistor
the photos resolution is too low to read the value

can you either post a photo that shows the 3 numbers printed on the resistors or just say what the resistors are in your reply
