Routing a digital input to a digital output on NI USB 6501

Hi,

I'm looking for instructions on how to route a digital input to a digital output on the NI USB 6501, but I haven't found such instructions.

To be clear, I don't want to write a software control loop or poll the input and update the output via software.  I would like to have this done in the device hardware.

Thanks,

  Ury
