need help with multi-function daq deployment

[paris1_]

Hi...  I need to purchase an inexpensive multi-function daq board (pci) where I need a minimum of 2 analog inputs and 2 analog outputs...  I am looking at maybe something like the NI-6221 or maybe the NI-6229 if I want a couple of spare analog outputs (4 total instead of 2)...  My main question is about compatibility of NI-DAQmx drivers...  Does the version of LabVIEW I am using matter???  The current deployment I am working on and what would be intended to interface software wise to this DAQ card would be LabVIEW 7.1...  Does the older version of LabVIEW (7.1) play well with newer cards like the NI-6221 (or 6229) and with the newer NI-DAQmx drivers???  Would the Traditional DAQ drivers come into play with what I'm describing here???  And last, does the NI-DAQmx drivers come with these PCI cards or do you just download those drivers separately???  But the bottom line is can I use these cards and the NI-DAQmx drivers with overarching LabVIEW code written in LabVIEW 7.1??? 

Any help would be much appreciated...  thanks much...  bob...

Hi,

NI-DAQmx 8.7.2 is the latest version which supports LV 7.1 as well as the devices you mentioned.

If you allready have DAQ code in LV 7.1 you have to determin if it's written with traditional DAQ or DAQmx, because traditional DAQ does not support the mentioned devices! If you start with a new development I don't see any problems.
