6009 digital input gives output

Hello,

 

I'm having a problem with my NI 6009 device. It is connected to a EASYmx Pro V7 board with input and output pins (6 output and 4 input).

 

With these input pins i want to read the LED's of this board. P0.0 is connected and labeled as input in MAX and in my VI and works properly. The same for P0.1.

My problem are the P0.2 and P0.3 pins. They are connected exactly the same way as the other 2 pins for reading the LED's but they have an logical 1 output when i give them the "input property" (MAX shows the input property of those pins as logical 1 and LabVIEW just reads a true when connected). After changing them of input to output and turning the output to 0 they switch back to 1 as soon as i hit the start button.

 

Best regards,
