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
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.
You also can specify whether the samples are paused when ao/PauseTrigger
is at a logic high or low level.
Routing AO Pause Trigger Signal to an Output
Terminal
You can route ao/PauseTrigger out to RTSI <0..7>.
AO Sample Clock Signal
Use the AO Sample Clock (ao/SampleClock) signal to initiate AO samples.
Each sample updates the outputs of all of the DACs. You can specify an
internal or external source for ao/SampleClock. You also can specify
whether the DAC update begins on the rising edge or falling edge of
ao/SampleClock.
