6501

Hello Everybody,

I am using a NI USB 6501 for the first time.

For now I am doing a small project: one output and one input connected to one digital sensor(detected and not conected). After some experiences I notice that when you are using a port like a input, the input is always with value "1"(4,7v) when nothing is connected. How I can change that?Basicaly I want "1" when "object detected" and "0" when "no object detected".

In worst case I can invert the sensor signal...
