Name
Reference Direction Description
AI<0…15> AIGND Input
Analog Input Channels 0 through 15. Each
channel pair, AI (i = 0, 2, 4...14), can be
configured as either two single-ended inputs or
one differential input.
AIGND - -
Analog Input Ground. These pins are the
reference points for single-ended
measurements and the bias current return point
for differential measurement. The three ground
references (AIGND, AOGND, and DGND) are
connected together on the PCI-1710/1710HG
card.
DA0_ REF AOGND Input
Analog Output Channel 0 External
Reference. This is the external reference input
for the analog output channel 0 circuitry.
DA1_ REF AOGND Input
Analog Output Channel 1 External
Reference. This is the external reference input
for the analog output channel 1circuitry.
DA0 _OUT AOGND Output
Analog Output Channel 0. This pin supplies
the voltage output of analog output channel 0.
DA1 _OUT AOGND Output
Analog Output Channel 1. This pin supplies
the voltage output of analog output channel 1.
AOGND - -
Analog Output Ground. The analog output
voltages are referenced to these nodes. The
three ground references (AIGND, AOGND, and
DGND) are connected together on the PCI-
1710/1710HG card.
