Michael:
The drivers that Corelis supplies are almost useless. If you are VERY lucky, you'll be able to get a DLL from Corelis, which you will then have wrap into a set of VI's manually. If you are brave you can creat your own by using A32/D32 writes to load binary programs into the controllers memory, then use Sord Serial protocal to execute the programs. NOT for the faint hearted.
This is just for their VXI system. If you are using PC based, or something, then this may not apply.
A better option is with Huntron/Goepel. We are looking at their VXI system which has VISA drivers and also a SCPI command interface. This is 100% LabWindows and LabVIEW compatible. You have to buy software as well, but it is relativly inexpensive ($2k - $3k for basic sfotware vs
$6k for basic software from Corelis).
Hope this helps you out a bit.
