Can DAQ boards be configured as a single port?

[EJonZ]

I'm simply wondering because I would like to just call the bit (0-63) on the PCI-6514, for example, to turn off or on.  This would simplify my class I need to write.

Hi ejones,

The 6514 has 32 input lines and 32 bit output lines. You can configure all 32 input or output lines on the 6514 to act as a single port by creating a digital 32 bit port and reading or writing a 32 bit integer. The NI-DAQmx C Reference Help is a very useful file which contains all DAQmx function calls and can be found under Start » Programs » National Instruments » NI-DAQ.
