To use DO Pause Trigger, specify a source and a polarity. The source can
be one of the following signals:
• PFI <0..15>
•RTSI<0..7>
•PXI_STAR
•Counter n Internal Output
•Counter n Gate
•AI Pause Trigger (ai/PauseTrigger)
•AO Pause Trigger (ao/PauseTrigger)
•DI Pause Trigger (di/PauseTrigger)
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 Help for more information.
You also can specify whether the samples are paused when DO Pause
Trigger is at a logic high or low level.
Using an Analog Source
When you use an analog trigger source, the samples are paused when the
Analog Comparison Event signal is at a high level. Refer to the Triggering
with an Analog Source section of Chapter 11, Triggering, for more
information.
