vrf Help with VEE 7.5 and NI-DAQ

Question asked by VRFuser on Jun 28, 2005
I just got this information when asking support about this.

"It seems that VEE 7.51 supports only the traditional NI-DAQ 7.4 drivers, not the new NI-DAQmx drivers."

I was planing of using one of the low cost USB DAQ the have, since the support wasn't there I've stick to a spare solution.

      Thanks to a clue from Willie Kiely <Willie.Kiely@bourns.com>, I
figured out that VEE 7.5 currently only supports older National Instruments
hardware.  Specifically, it only supports hardware that can be programmed
with the "Traditional NI-DAQ (Legacy)" driver.
      So, I added an older NI PCI-MIO-16E-1 to my system, VEE found it, and
I was able to acquire data.
      I also added a National Instruments PCI-5431 video signal generator
to my system.  That worked pretty much "out of the box".
      I haven't used VEE 7.5 much, but my impression is that Agilent's done
a better job integrating NI's instruments (scopes, DMMs, arbs, etc.) than
they've done integrating NI's general purpose DAQ boards.  I suspect the
VEE team is working on support for NI-DAQmx, which should improve usability.
