PCI-6110E/6111E User Manual

PFI6/WFTRIG

DGND

Input

Output

PFI6/Waveform Trigger—As an input, this is one of the
PFIs.

As an output, this is the WFTRIG signal. In timed analog
output sequences, a low-to-high transition indicates the
initiation of the waveform generation.

PFI7/STARTSCAN

DGND

Input

Output

PFI7/Start of Scan—As an input, this is one of the PFIs.

As an output, this is the STARTSCAN signal. This pin
pulses once at the start of each analog input scan in the
interval scan. A low-to-high transition indicates the start of
the scan.

PFI8/GPCTR0_SOURCE

DGND

Input

Output

PFI8/Counter 0 Source—As an input, this is one of the
PFIs.

As an output, this is the GPCTR0_SOURCE signal. This
signal reflects the actual source connected to the
general-purpose counter 0.

PFI9/GPCTR0_GATE

DGND

Input

Output

PFI9/Counter 0 Gate—As an input, this is one of the PFIs.

As an output, this is the GPCTR0_GATE signal. This signal
reflects the actual gate signal connected to the
general-purpose counter 0.

GPCTR0_OUT

DGND

Output

Counter 0 Output—This output is from the general-purpose
counter 0 output.

FREQ_OUT

DGND

Output

Frequency Output—This output is from the frequency
generator output.
