No battery voltage readings on DS!

What the jumper does is steal the signal pin from that analog input for use as the battery detector.
If the jumper is put over the other (inside) pin then analog input 8 acts like a normal input in the alternate analog cRIO module slot.

Opening Analog Module 1's analog input 8 is a no-no because it's already opened by the battery monitor.
