Connector Pins Configuration

– Non-Referenced Single-Ended (NRSE) Mode
In NRSE mode, the DAQ device does not provide the grounding point. The
ground reference point is provided by the external analog input signal. You
can connect the signals in NRSE mode to measure ground-referenced
signal sources, which are connected to the same grounding point. The
following figure illustrates the connection. The signal local ground
reference is connected to the negative input of the instrumentation
Amplifier (AI_SENSE pin on connector1). Hence, any potential difference of
the common mode ground between signal ground and the signal ground on
DAQ board will be rejected by the instrumentation amplifier.
