Hello David,
I ran into the same problem while trying to update some (really) old VIs
from a Windows 3.1 / 486 system to LabView 5.1 on my PowerBook G3 (Bronze
- no FireWire) using the network connection and an ENET GPIB box. They ported
over well enough, but I had to replace some of the old GPIB Read / Write
VIs and re-wire them. That seemed to work o.k., but then I thought I should
swap out the old instrument drivers with the latest ones I downloaded from
the web (HP662XA Programmable Power Supply). That's when the VIs started
to freeze my machine.
After looking inside the instrument drivers, I noticed that they use the
VISA VIs instead of the GPIB read, write, etc. VIs.
There's some difference in the wiring, but, I would suggest trying to replace
the VISA VI
s with the GPIB VIs. I'm sure you'll have to do some wire-work,
but I'm optimistic that'll do the trick.
FYI: The setup is used to control a HP6626A programmable power supply to
reverse-bias a solar cell under a solar simulator to create the points for
a current-vs-voltage curve for the cell.
Good luck,
