AI Pause Trigger Signal
You can use the AI Pause Trigger (ai/PauseTrigger) signal to pause and resume a measurement acquisition. This signal is not available as an output.
Using a Digital Source
To use ai/PauseTrigger, specify a source and a polarity. The source can be an external signal connected to any PFI or RTSI <0..6> pin. The source can also be one of several other internal signals on your DAQ device. Refer to Device Routing in MAX in the NI-DAQmx Help for more information.
Also, specify whether the measurement sample is paused when ai/PauseTrigger is at a logic high or low level.
Using an Analog Source
When you use an analog trigger source, the internal sample clock pauses when the Analog Comparison Event signal is low and resumes when the signal goes high (or vice versa).
 | Note Pause triggers are only sensitive to the level of the source, not the edge. |
