Figure 4-3 Incorrect method for connecting a grounded
signal to differential input
If you have combinations of signals in your application,
the 8-channel differential input configuration should be
used. To connect a floating signal source to the differential
input, connecting a jumper wire between negative and
analog ground of AR-B3001 effectively turns the
differential input into a single-ended input. Figure 4-4
shows how to connect a floating signal source to the
differential input.
