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.

Everything is right in this post other than the roboRIO does not have an internal pullup resistor. You will need to add a pullup resistor between your signal and your positive pin. We had to do the same on our robot. I wish they would have designed the pull up resistor internally like on the cRIO.
