PCI-QUAD04 and LabVIEW using MCCDAQ.DLL (.NET)
At the time of this writing (5/2012) Measurement Computing does not include encoder support in ULx nor 64 bit.
But it can be done!
Here is an example program demonstrating the implementation of .NET reference in NI LabVIEW 2009 (64 bit)
Hardware used: PCI-QUAD04
OS: Windows 7 64 bit
InstaCal 6.23
This VI was also tested and successfully in LabVIEW 2009 32 bit and LabVIEW 2011 32 bit.
