In any case, if you connected both black and white outputs of the Banner sensor to the same wire, you'd always see the result at ground.

I meant that we cannibalized a PWM signal cable, and then connected through that to the lines on the digital sidecar input.

We only temporarily connected the signal line to the analog breakout to see if there was any slight voltage fluctuation when the sensor switched between states.

We have tried both the NC/NO wires as the signal line. I meant that we plugged the PWM cable female end into the digital input sideways, so that all three wires on the line were going to one of 3 digital input signal lines on the digital sidecar (not ground or power). This was to save killing even more cables to test both the NC and NO lines at the same time.
