Data Entry Unit
This is the Tornado cockpit Data Entry Unit which has a drawer for the Transfer Data Module 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 (Read Only) electro-optical data interface that is more rugged than normal mechanical electrical connectors (See picture in C0231). This interface structure can be seen more clearly on the TDM.
This unit is missing its door/cartridge latch.
