Most of these boards are set up so that you just run a ribbon cable to a squeeze on type DB-25 connector.  If there are less pins on the header on the circuit board than on the DB-25 align the pin 1 designations.  Don't know for sure if the DTK board is this way but all of the others I have seen are.
