usb-6501 no supported devices found

Dennis, I read you wrote something about dig in/out for some other member.

Can I input my voltages ranging from 3 to 5v and make the usb-6501 see them as logic 1?

The problem is that no matter what input i use, they all read 4.7v, so when I run the Create Task, acquire signal, digital input, I am reading high on all pins.

How can I make it stop providing a logic high, and correctly read my high/lows that i input externally?

Thank you for any support.

A signal between 3 and 5 volts is a logic 1. If you ground an input, don't you see it as a logic 0?
