You're using terms that don't match the names of the 2009 FRC Control System components, and that's keeping me from fully understanding what you want to do.
When you say "digital io board", do you mean the Digital Sidecar? If so, then you wire signals to the "signal" pins of the GPIO headers.
What "other two" are you referring to?
If you want to connect to a computer's serial port for communication to and from the cRIO, you really only need two signals: TX and RX.
