+5 V
DGND
Output
+5 VDC Source—These pins are fused
for up to 1 A of +5 V supply. The fuse
is self-resetting.
EXTREF
AOGND
Input
External Reference—This is the
external reference input for the analog
output circuitry.
EXTSTROBE*
DGND
Output
External Strobe—This output is used
for controlling SCXI modules.
PFI0
DGND
Input
PFI0—As an input, this is one of the
Programmable Function Inputs (PFIs).
For more information on PFI signals,
see the
6711/6713/6715 User Manual
.
You cannot use PFI0 as an output.
PFI1
DGND
Input
PFI1—As an input, this is one of the
PFIs. You cannot use PFI1 as an
output.
PFI2
DGND
Input
PFI2—As an input, this is one of the
PFIs. You cannot use PFI2 as an
output.
PFI3/GPCTR1_SOURCE
DGND
Input
PFI3/Counter 1 Source—As an input,
this is one of the PFIs.
Output
As an output, this is the
GPCTR1_SOURCE signal. This
signal reflects the actual source
connected to the general-purpose
counter 1.
PFI4/GPCTR1_GATE
DGND
Input
PFI4/Counter 1 Gate—As an input,
this is one of the PFIs.
Output
As an output, this is the
GPCTR1_GATE signal. This signal
reflects the actual gate signal
connected to the general-purpose
counter 1.
GPCTR1_OUT
DGND
Output
Counter 1 Output—This is the
general-purpose counter 1 output.
