It's a great question, those things should always be checked first. We connected the sensor output to the DIO signal input of the DSC. The DSC has 12V power (verified). We didn't verify the 5V from the power pin of the DIO breakout, but we will tonight. For what it's worth, we're running several speed controllers and servos from that DSC, so we didn't think about checking the DIO power.

Thanks for the feedback!
