How should we wire the photoswitchs?

We connected the brown and blue wires to the 12V out on the PD board and the black and white wires (in turn) to the DSC with no results. The voltage output from the sensor is 0.38V for off and 0.76V for on (or vice versa, depending on which wire you use), and doesn't seem to be a big enough difference for the DSC to distinguish.

What we're going to try next is to pull in a relay when the load shifts that will send the 5V supply from the DSC back to the 5V signal. I'll post an update if this works.
