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.
