Wiring previous-year banner sensors

You can not get power from the digital sidecar for your banner sensor as it can only deliver 5 volts to the digital IO.

That's how we currently have it wired. The sensor is active as well, showing correct status indications on its LEDs. Also, like I said, if checked with a voltmeter it sends the correct signals. However, if I hook this same line up to a SIG line on the digital sidecar and declare it as an input in code, it does not change in value when the sensor switches. The same code detects switching properly with a microswitch.

We have tried two banner sensors.
