Table 3 shows how to set the NRSE/RSE switch (S1).
Chassis Ground
Chassis ground provides a connection between the enclosure and USB
ground.
D GND is connected to the chassis ground at the bottom edge of the board
through two 0
Ω
resistors. The chassis ground directly connects to USB
ground, which connects to earth ground. Figure 6 shows where the different
grounds are connected.

To make RSE measurements, you must set the Analog Input Terminal Configuration property of your AI Task to NRSE in
NI-DAQmx. Even though RSE mode is not exposed in the software, setting S1 to RSE and setting the Analog Input Terminal
Configuration property of your AI Task to NRSE will allow you to make RSE measurements.
