I'm controlling a Newport 842-PE optical power meter with Labview 8. All I would like to do is simply conduct a multi-point measurement of arbitrary length and sampling rate. What I've been doing is using the Newport provided drivers to tell the power meter to start logging and then stop logging using the "Setloggingstart-top.vi". Then I use the "filedownload.vi" to get the array from the power meter. At seemingly completely random times the filedownload.vi will output a timeout error and no data will be collected. The timeout error doesn't necessarily seem to simply be due to the power meter doing something weird. The driver's condition for a timeout is very strange and difficult for me to understand. I've attached an image of the .vi I've been using to attempt to diagnose the problem. It simply repeats this logging command and filedownload command indefinitly so I can see when it times out. Here is an image of it.
Does anyone have experience using Labview with this power meter? Can you think of an alternate or correct path I should be taking to conduct a multi-point measurement? So far the techies at Newport haven't been able to figure out why this is happening. Please let me know if there's any other information you would like me to provide.

Would you attach those 2 vis so we can open them and see what those sub-vis are doing?
I tried to find them on Newports website but I didn't see them.
