uninstalled/reinstalled NI visa 5.4, NI max now hanging (searches for instruments indefinitely)

[edCubed]

Hi all,

I did the following and now NI MAX is hanging and searching for instruments indefinitely:

1) uninstall NI visa 5.4

2) install NI visa 5.3

3) uninstall NI visa 5.3

4) install NI visa 5.4 again.

I did all this because I have a GPIB instrument that max sees as a miscellaneous resource.

If anyone has any ideas please let me know,

Thanks,

ed,

I would suggest installing the most recent version of NI-488.2 which can be found here: http://www.ni.com/nisearch/app/main/p/bot/no/ap/tech/lang/en/pg/1/sn/catnav:du,n8:3.25.123.785,ssnav...

Try scanning for the instruments in MAX after you have installed the 488.2 driver.  You can also use NI I/O Trace or GPIB Analyzer to see if you can detect anything out of the ordinary.  Take a look at these two links for NI I/O Trace and GPIB Analyzer instructions:

Thanks for the advice Michael, I will give it a try.

It seems that unplugging my GPIB cable then plugging it in again temporarily fixes the problem and alows MAX to find all instruments.

Is this another symptom of needing to update NI-488.2 or are there other things that could cause this?

Thanks again,

I found an updated driver for my GPIB to USB cable from keithley ( KUSB-488A driver v9.2).

I think everything is working now with the updated driver, so I will not install the latest version of NI-488.2.

But thanks for your help, hopefully my GPIB woes are solved for the time being.
