OmniDriver, USB2000+, LabVIEW7.1

[adrewery87]

 Hello,

 I am currently an undergraduate student at the University of Missouri.  I am attempting to control the USB2000+ spectrometer with LabVIEW 7.1.  I have fresh installs of LabVIEW as well as OmniDriver, and followed the video instructions provided by Ocean Optics to create a basic spectrometer.  When I run the vi LabVIEW closes.  There are no errors generated, the arrow is not broken before run, and I have double and triple checked my work.

I have searched through the forums here and have searched all over Ocean Optics website and have had no luck.  Anyone who has had similar errors I have tried their fixes; leaving the spectrometer unplugged until I need to use it, removing OOILVD.dll (or something close to that) in C:\Windows.

Has anyone else had issues occur with this.  I am still relatively new to LabVIEW as well, so I'm sure there's some simple fix that I'm just not thinking of.

Thanks,

Adam

Hi,

OmniDriver was always pretty iffy about giving errors.  In my experience, nearly any problem with the spectrometer caused a fatal crash with no error message.  I always suspected that it had something to do with the way the driver was implemented in Java.  I suppose you could try updating or even uninstalling/reinstalling the Java RunTime Engine, but the odds are small that it would help.  My advice to you would be to move to the new LabVIEW supported drivers found at:

They are much easier to use and far more robust.  Give them a look - and if you hit a sticking point with them, post back here and I'll try to give you a hand.
