Hi jchrisj,
You may have looked at this already, but when you have the context help window open for a particular VI, there is a link to the “Detailed Help” for that VI at the bottom of the window. This opens up the LabVIEW Help (which can also be accessed by going to Help >> Search the LabVIEW Help) which does provide some more detailed information about the VI.
Another great resource is the DAQmx Help File. I am not sure of its location in the Linux environment, but on Windows XP it is located by going to Start >> Programs >> National Instruments >> NI-DAQ >> NI-DAQmx Help. The following link shows the available documentation for DAQmx:
NI-DAQmx Installed Documentation
Beyond the documentation there are some great resources for learning about how to effectively program using DAQmx. Here are some useful links:
Getting Started with NI-DAQmx: Main Page
Learn 10 Functions in NI-DAQmx and Handle 80 Percent of Your Data Acquisition Applications
Another suggestions is to open the LabVIEW Example Finder (with LabVIEW open go to Help >> Find Examples). In the Example Finder on the right hand side of the dialog box you can navigate to some great DAQmx examples by going to Hardware Input and Output >> DAQmx and then going to the folder that represents the kind of measurement you want to take.
Hope this helps.
Jared T.
