Sometimes what you get from the vendor is a DLL (and supporting documentation). From this, you can use LabVIEW's Call Library Function to access the DLL. This should work most of the time but if the author of the DLL has used datatypes that are not supported by LabVIEW, then you might have to write a wrapper in C to do some conversion. If you're lucky, the vendor will provide a set of LabVIEW VIs that they've written that incorporate communication with their DLL. You will not find any card that you will be able to use with MAX or the LabVIEW data acquisition functions. Those rely on NI-DAQ which is strictly for NI manufactured DAQ boards.
