All the literature says you can do this and you can do that but all of it falls short on HOW. I've used DAQmx many times for various things but can't seem to find exactly how to set the direction of the port, set the open drain or pull up and set functionality of P2.7 DIO or timer, for the USB-6501. None of the examples I've seen so far help either. Yes they show the physical lines, init, start, read / write and stop etc, but how to configure the items mentioned???

Hello fdfdfdvkue,
Based on your description, it sounds like what you're looking for is the DAQmx Property Nodes as described here:
Tutorial: NI-DAQmx getting started: Property nodes
http://www.ni.com/white-paper/5470/en/
The first link on that page should get you started; right-click on a session wire and select create>>property to create a DAQmx property node. The specifics on using the properties you've mentioned will be found in the DAQmx help.
Regards,
