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.
- Analog Input Ground. The three
ground references (AIGND, AOGND,
and DGND) are connected together on
the PCI-1710U/1710HGU/1710UL.
Input Analog Output Channel 0/1 External
Reference.
Output Analog Output Channels 0/1.
- Analog Output Ground. The three
ground references (AIGND, AOGND,
and DGND) are connected together on
the PCI-1710U/1710HGU/1710UL.
Input Digital Input Channels 0 through 15.
Output Digital Output Channels 0 through 15.
- Digital Ground. This pin supplies the
reference for the digital channels at the
I/O connector as well as the +5VDC
and +12 VDC supply. The three ground
references (AIGND, AOGND, and
DGND) are connected together on the
PCI-1710U/1710HGU/1710UL card.
Input Max. Input Frequency: 10 MHz
Output Counter 0 Output.
Input Counter 0 Gate Control.
Output Pacer Clock Output. This pin pulses
once for each pacer clock when turned
on. If A/D conversion is in the pacer
trigger mode, users can use this signal
as a synchronous signal for other
applications. A low-to-high edge trig-
gers A/D conversion to start.
