Data Entry Unit
This is the Tornado cockpit Data Entry Unit which has a drawer for the TDM (C0231, C0559) data cartridge and provides the interface to the aircraft systems. The drawer for the TDM has 12 round glass-windowed photo-transistors, interspersed with photo-diodes to form a 12-bit electro-optical data interface that is more rugged than normal mechanical electrical connectors. This interface structure can be seen more clearly on the TDM.
This unit is missing its door/cartridge latch.
