I need know the configuration of the pines at output of the pcdio24 card,

I need know if as an vi.at labview that relizate an test of output signal.

If memory serves me correctly, I believe the lines are driven low when you configure them for output. But the best way to test the state of the lines is to wire the outputs of one port(say, A) to the line of another port (B) configured for inputs. You can perform a simple write to Port A and then read back the values given to Port B.

Also, when working with the DIO-24, keep in mind the behavior of the 8255 chip it uses for its digital functionality.

Here is a link to a KnowledgeBase article on the 8255: http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/862567530005f09c862564db00655dc4?OpenDocument
