I/O Connector Signal Descriptions

Signal

Name

Reference Direction Description

AI<0…15> AIGND Input

Analog Input Channels 0 through 15. Each

channel pair, AI<i, i+1> (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

Referenc

e. 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.
