Did you type that name into the VISA Resource or was it something you were able to select from the drop down?

Generally, attaching the front panel isn't very helpful by itself.  We can't see your MAX settings.  We can't see any of the code.  Seeing the forums as backdrop offers almost nothing to help determine the issue.

Would it be simpler for me to buy one of these?

GPIB seems more straight forward...plus the cards NI tested

The error is with VISA, not GPIB. If you notice, it says possible reasons.

Have you done any probing to see where the error occurs?

GPIB is faster and more robust than serial. I don't know of a reason for error 0 popping up so that may not fix your problem.

It appears that the GPIB-USB card was not the panacea I had hoped.  I'm still getting the time out error.

I've was able to obtain a GPIB-USB national instruments card and connect the fluke 2620 via usb.  The fluke and GPIB card both show up in max. What is encouraging is that from the VISA test panel screen-->Input/Output-->  no errors occur on "write" or "query". But I am getting a timeout error on "read" despite the "remote" light showing up on the fluke display when i hit the button.

 Also, from the VISA test panel -->Advanced --> Triggers, I can get the fluke to scan once when I click the "assert trigger" button on the test panel screen. 

The GPIB USB seems to have improved things a bit...but not solved all my problems.

The query option automatically does a read after the write so if you don't get an error there, the read is working. What is the actual command you are sending before doing the read?
