Configuring Jumper W1 - Common Ground Sense

When shipped from the factory, jumper W1 connects the low side of the input amplifier (Amp
Low) on the DT3010, DT3010/32, DT3010/32-268, or DT3016 board to analog ground.
When using pseudo-differential analog inputs, remove jumper W1 and connect Amp Low to a
remote common-mode voltage to reject offset voltages common to all 32 input channels. Refer
