Hello,
I am not sure what VI you are referring to when you say "NI-HSDIO.vi", but here's some general information. In LabVIEW there is a whole palette of DIO functions at Functions->NI Measurements->Data Acquisition->Digital I/O. Now, depending on whether you want to do high speed operations (requiring a buffer) or you want to do static operations will depend on which VI's to use there. There are several examples using the 6534 that are shipped with LabVIEW that you can find by using the Example Finder in LabVIEW. They are located at "Hardware Input and Output->Traditional DAQ->Digital Input and Output -> 653X"
If this information doesn't help you, please reply with some more information on your application. Namely, what software are you using to progra
m this system?
