With the 6503 you can use DAQmx and the assistant. I would suggest
first of all Going into MAX and setting up your channels in there. See
Manual or help. Or you can use the assistant to do this for you. Drop
the assistant onto the block diagram and let it come up then select
digital I/O. from there

hardware to go with the program I've made. I haven't been able to
figure out if I should use the DAQ
