QS18VN6LP: Wiring Diagram???

• White or Black goes to the SIG pin of a DIO port on the roboRIO.

That's all. The White wire goes active when the sensor sees a reflection; the Black wire is active when the sensor does not see a reflection.

The "load" on the diagram is misleading. It isn't something you need to add; it is provided by the internal pullup resistor on the roboRIO's DIO pin.

When we got to competition, our inspector pointed out that the wire was too small of a gauge for a 20amp breaker and asked us to move it to the VRM.
