The PCI-5112 can only be programmed with NI-Scope. That's why the PCI-5112 does not work with the DAQ Solution Wizard.
Fortunately, there are lots of good examples for NI-Scope in LabVIEW. You can find these in the C:\Program Files\National Instruments\LabVIEW 6.0\examples\instr\niScope directory. I would recommend starting with the Configured Acquisition example and then going from there depending on the needs of your application.
Hope this helps,
Jack
