AI (X) and AI (X+8) are the analog input signal channels of the E Series
DAQ device. AI GND is the analog input ground signal and is the reference
for AI (X) and AI (X+8). A GND is the reference for the ±15 V supplies and
REF 5 V. AI GND and A GND connect to the SC-2345 at the SCC-PWR
connector. Pins 17 to 20 accept inputs from a first-stage SCC module if you
are cascading two modules.
