Hi
It's important to know that the PCI-1200 is not supported by NI-DAQ 7.0 (NI-DAQ 7.0 Traditional and NI-DAQmx). If you've installed this driver version (NI-DAQ 7.0) then you must uninstall it, and install NI-DAQ 6.9.3. This will work with LV 7.0. Of course you cannot use new DAQ features (DAQ Assistant,...) with the 6.9.3 version. Check this to see which board is supported by which driver version:
