2 Startup Manual
*Note: Pins 23~25 and pins 57~59 are not defined for PCI-
1710UL.
*Note: The three ground references (AIGND, AOGND,
and DGND) are connected together.
Analog Input -
Single-ended Channel Connections
The single-ended input configuration has only one sig-
nal wire for each channel, and the measured voltage
(Vm) is the voltage referring to the common ground.
Analog Input -
Differential Channel Connections
The differential input channels operate with two signal
wires for each channel, and the voltage difference
between both signal wires is measured. On PCI-1710U,
when all channels are configured to differential input,
up to 8 analog channels are available.
Analog Output Connections
PCI-1710U provides two analog output channels, AO0
and AO1. The figure below shows how to make analog
output connections on PCI-1710U.

Digital Ground. This pin sup-
plies the reference for the dig-
ital channels at the I/O
connector as well as the
+5VDC and +12 VDC supply.
CNT0_CLK

Input
Counter 0 Clock Input.
CNT0_OUT DGND
Output
Counter 0 Output.
CNT0_GATE DGND
Input
Counter 0 Gate Control.
PACER_OU

DGND
Output
Pacer Clock Output.
TRG_GATE DGND
Input
A/D External Trigger Gate.
When TRG _GATE is con-
nected to +5 V, it will enable
the external trigger signal to
input.
EXT_TRG
DGND
Input
A/D External Trigger. This pin
is external trigger signal input
for the A/D conversion. A low
-to-high edge triggers A/D
conversion to start.
+12V
DGND
Output
+12 VDC Source.
+5V
DGND
Output
+5 VDC Source.
