Ocean Optics LabVIEW 8.2 drivers not working with USB2000

[rray2]

Hi All,

I've recently begun working with the USB2000 in LabVIEW 8.5.1. I downloaded the drivers from NI's instrument driver page and tried to install and run them.  When I did this, an error message popped up saying these drivers were meant for LabVIEW 9. Has anyone else had this problem and does anyone know how to fix it?

Thanks,

Rob

Sounds like you may need to down convert them from 9 (i.e., you need someone with 9 to do this).  The unfortunate aspect of this is that there may be some features which are used that prohibit you from using the drivers without some rewriting.

And, it's not immediately clear what the show stopper is when I download this.  When are you getting the error?

When I try and open one of the VIs in the example folder, the following error message pops up:

An error occured loading VI 'Ocean Optics 2000 4000 *.vi'.
LabVIEW load error code 9: VI version (9.0) is newer than LabVIEW version (8.5.1).

I also went and checked out the "Ocean Optics 2000 4000.lvlib" file under

C:\Program Files\National Instruments\LabVIEW 8.5\instr.lib\Ocean Optics 2000 4000

and saw that the second line comes to <Library LVVersion="9008000"> whereas the same line for an Agilent instrument I have installed comes out as <Library LVVersion="8508002">

As far as I can tell, this indicates the Ocean Optic files are meant for 9. Do you see this as well with these files?

You established in your first post that someone did not put the correct project on the web site. Wait for NI to correct it or just get on with it and post the project in the Download Convert thread.

Yes, it does appear that someone forgot to save for another version.  Follow Dennis' directions so that you can get this correctly converted.

Cheers, Matt
