In an RSE configuration, the NI 9205 measures each channel
with respect to COM. To connect RSE signals to the NI 9205,
you must connect the voltage ground signal to COM to keep the
maximum working voltage in the specified range.
Note
If you leave COM unconnected, the signals float
outside the working input range of the NI 9205. This
