There's no drivers for that in the NI Instrument Driver network, and the company's web site doesn't seem to have anything, though this is not that big of a surprise. Given that it has C++ commands it's quite likely it's calling functions in a DLL. If that's the case, you can create LabVIEW wrapper functions for the DLL functions. Can you tell if it's using a DLL? This information would likely be in a programming sub-manual, or a section in the user manual dealing with programming. Given the type of device it's also possible that it might just be talking to it directly via TCP/IP. Can you provide a code snippet that is in the manual, or a link to the manual?
