Upgrade

[anil108]

We have code written in LabView 2007. It used the GPIB card stalled in the computer.

With the updates on computers, we had to get rid of the old computer.

 So we bought the NI-USB interface for the GPIB.

The code does not run. We tried with Labview 9.

We are looking for someone in the Dallas area who can help/guide us in this matter.

(we are in TAMU-Commerce)

The code is written for the standard resistivity measurements. The instruments used are Keithley K220,

 Keithley voltmeter 2182, and the Neocera LTC 11 temperature controller.

Having done this several times myself I can confidently say if the NI-USB GPIB was installed properly it should have been seamless, but...

What error are you getting? 

Did you install the drivers and update NI-VISA and NI-488.2?

Did you verify it was set up right in NI-MAX?

Did you set up and verify all your instruments in NI-MAX?

Does the program use VISA alias instead or hard coded GPIB address?

If alias, did you set up the same alias on the new machine?

If hard coded address did you verify all your instruments are on the same GPIB address as before?
