VISA Error writing to instrument -1073807360

[billw4]

I cannot write when using VISA Write functions in Labview. However, using GPIB functions will work.
MAX tells me an Error Code of -1073807360 ("ViStatus returned from VISA function call") and Description - "viOpenDefaultRM returned 0xBFF0000"
I am using one NI PCI-GPIB, and I know it is board 0.

Bill:

Based on the screen snapshot, it looks like you have NI-VISA 2.5. I recommend upgrading to NI-VISA 2.6. If it doesn't fix whatever other problem you have (I'm guessing perhaps some of your NI-VISA 2.5 files got deleted?) then at least the MAX message should be more helpful.

Make sure the correct primary address is being used if the primary address of the device was changed and a scan for instruments was not performed afterwards then VISA might be accessing the wrong address. If you are assigning aliases then make sure you have the alias assigned to the right address.

Thank you. I downloaded VISA 2.6 and the problem appears to be resolved.
