The keyboard and feature connector is available through Connector X15002 (10 pins). An adapter cable is
required to connect a standard keyboard to this interface. There are two adapter cables available from Kon-
tron. One can be used for AT-keyboard (KAB-KB-1, Part Number 96023-0000-00-0), the other for PS/2-

tions on this interface.
