PIN Assignment
Signal Name Reference DirectionDescription
AI<0..15>
AIGND
Input
Analog Input Channels 0
through 15.
Each channel
pair, AI<i, i+8> (i = 0...7),
can be configured as either
one differential input or two
single-ended inputs.
AIGND -
-
Analog Input Ground.
These pins are the refer-
ence points for single-
ended measurements and
the bias current return point
for differential measure-
ments. All three ground ref-
erences - AIGND, AOGND,
and DGND - are connected
together on the PCI-1712
card.
AO0_REF
AO1_REF
AOGND
Input
Analog Channel 0 Out-
put External Reference.
This is the external refer-
ence input for the analog
output channel 0/1 circuity.
ANA_TRG
AIGND
Input
Analog Threshold Trig-
ger.
This pin is the analog
input threshold trigger input
AO0_OUT
AO1_OUT
AOGND
Output
Analog Channels 0 Out-
put.
This pin supplies the
voltage output of the ana-
log output channel 0/1.
AI_CLK
DGND
Input
Analog Input external
clock input.
This is the
external clock input for the
analog input.
AI_TRG
DGND
Input
Analog Input TTL Trigger.
This is the TTL trigger for
analog trigger.
AOGND
-
-
Analog Output Ground.
The analog output voltages
are referenced to these
nodes. All three ground ref-
erences - AIGND, AOGND,
and DGND - are connected
together on your PCI -1712
card.
