NIHSDIO - Property Node Output Number

NISHDIO Property Node allows many options to choose from, in a pull-down menu.  In an example I have a DataWidth that outputs the #4.  Is their a decoder or explanation that explains the output for each option in the pull-down menu?

ie.

DataWidth = 4

DataRate Multiplier = ?

and so on.

Any references to read would be useful as well.  Thanks
