Thank you for posting on the National Instruments forum.
I am not sure what you are trying to do. Are you trying to input and output at the same time? Are you just trying to synchronize all of your inputs? Do you want them to run off the same clock? If you could, give me some more information so I can understand your problem better.
In the meantime, this might help you:
