Hello;
You can find the NI-DAQ on line help at Start-> Programs->National Instruments->NI-DAQ->NI-DAQ Help.
At the on line help, you can find a list of NI-DAQ functions sorted by hardware type.
To find that list of functions, go to the on line help, select the Contents tab, select NI-DAQ functions-> Listed by Hardware type->NI-DAQ functions.
Hope this helps.
