Hello Eric,
I came to this thread because I'm also trying to interface a fluke hydra 2620a using Labview 2014 and the labview driver located on the NI website at the following address:
I've also installed NI-VISA 5.2 for my windows 7 PC.
After installing the fluke 262x driver folder, I tried opening the example VI's (Fluke 262X Series Acquire Scan Measurement Review, Fluke 262X Series Acquire Measurement, etc.), then pointing the browser to the filepaths for two files *.lvlib and initialize. After the front panel comes up, I set all the com parameters to match those on my fluke 2620, i.e. 9600 baud, com port4, no parity, etc. Since I'm using a USB to RS232 dongle, I made sure to check device manager to take note of the com port used for my dongle (i.e. com 4, in this case). After clicking the run arrow, the program hangs and says something like, "could not locate GPIB device, etc.etc." .
Any idea as to why this is happening/ how to resolve this?
thanks

"Also" is a pretty liberal word to use in this case. I doubt they were trying to interface with LabVIEW 2014 in 1999.

I'd start with downloading that version of VISA. After all, http://digital.ni.com/public.nsf/allkb/CF4279A34F855AB186257B1F00003B82 shows you 5.2 hasn't been compatible since LabVIEW 2012.

I installed NI-VISA 14.0.1 but I still can't my device is still not found when I try to open any of the example VIs.
Opening MAX, I see an instrument connected via "ASRL3:INSTR", this is the usb-serial adapter with my fluke. I opened the VISA test panel for this instrument and upon clicking query, from the VISA test panel, it returns "fluke, 2620a, etc"
I did a search in the help index for "VISA resource control" but did not find that entry. perhaps there's a setting I'm missing.

Dennis, I did go back and find the specific driver for my fluke 2620 under the instrumentation-->Find instrument driver menu. thanks for that. That seemed to put those example VI's in the Labview menu screen. But they still hang up with a device not found message.

I'm really questioning whether this 2620A driver is bogus. Visa Interactive Control returns the following for my instrument...
ASRL3::INSTR
VISA: (Hex 0xBFFF0072) The resource is valid, but VISA cannot currently access it.

Remembering some pit falls bach from the days when I read 4-10 different RS232 devices (incl. the Hydra)
1. Make shure you have the rigth cable.... not only the rigth connectors 😉
2. correct and identical serial settings
3. try a simple write read to test the communication
here I posted my rs232 swiss army nife (the software, the hardware part was a rs232 universal adapter ..)
