ao/PauseTrigger with Other Signal Source
Using a Digital Source
To use ao/PauseTrigger, specify a source and a polarity. The source can be
one of the following signals:
•
Input PFI <0..5>
•
RTSI <0..7>
•
PXI_STAR
Note
Refer to the
NI 6238/6239 Specifications
for the minimum allowable pulse width
and the propagation delay of PFI <0..5>.
The source also can be one of several other internal signals on your DAQ
device. Refer to
Device Routing in MAX
in the
NI-DAQmx Help
or the
LabVIEW 8.x Help
for more information.
