AO Pause Trigger Signal
You can use the AO Pause trigger signal (ao/PauseTrigger) to mask off samples in a DAQ sequence. That is, when ao/PauseTrigger is active, no samples occur.
The ao/PauseTrigger does not stop a sample that is in progress. The pause does not take effect until the beginning of the next sample. This signal is not available as an output.
Using a Digital Source
To use ao/Pause Trigger, 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 samples are paused when ao/PauseTrigger 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.
