Using a Digital Source

To use ai/SampleClock, specify a source and a polarity. The source can be
any 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.

Routing AI Pause Trigger Signal to an Output
Terminal

You can route ai/PauseTrigger out to RTSI <0..7>.

Note Pause triggers are only sensitive to the level of the source, not the edge.

Getting Started with AI Applications in Software

You can use the M Series device in the following analog input applications.

Single-point analog input

Finite analog input

Continuous analog input

You can perform these applications through DMA, interrupt, or
programmed I/O data transfer mechanisms. Some of the applications also
use start, reference, and pause triggers.

Note For more information about programming analog input applications and triggers in
software, refer to the NI-DAQmx Help or the LabVIEW 8.x Help.
