I have a visual basic 6 program that measures IR using an agilent 4339B high resistance meter.
The existing working PC is running Windows XP and uses the NI GPIB-USB-HS and works great.
The original code is using the 32 bit Visual Basic Language Interface Version 1.7 by National Instruments with the NI-488 DLL .
When I try to use the NI GPIB-USB-HS+ controller it does not work. I installed the new driver for the NI GPIB-USB-HS+.
I unistalled the driver and went back to the NI GPIB-USB-HS controller and re-installed the correct driver for it and the program works.
I was trying to set the same program up on a different PC and could never get the program to communicate with the tester using the
NI GPIB-USB-HS+ controller. That is when I decided to verify the controller worked on the original PC and discovered it does not.
I also had the same issue with communications with cap bridges and had to re-write the programs using NI-VISA which the
NI GPIB-USB-HS+ works fine when with.
I would have thought the NI GPIB-USB-HS and the NI GPIB-USB-HS+ would both work on the same application without any
code changes required and just updating the driver.
Thank you in advance for any help you can provide on this topic.
