Passenger service units in an aircraft are equipped with a passenger interface and supply adapter (10). Each adapter includes an individual processor (14) which is programmable independently of the aircraft central control through a programming input. The programmable interface (10) permits controlling passenger service components in the passenger cabin such as lamps in a cabin lighting system, a public address system, and so forth, directly by the interface (10) independently of the aircraft central control. The interface (10) with its own individual processor (14) and memory (15) is connected through a databus (11) to the aircraft central control (12), for example, for remote programming of the interface and for reporting the module's activities to the aircraft central control. The interface (10) reduces the memory capacity requirements for the aircraft central control and permits the individual programming of each passenger service unit also independently of any other passenger service unit thereby avoiding retesting of the entire cabin system when for example only one passenger service unit is reprogrammed.

1. A passenger service unit (PSU) for an aircraft cabin, said passenger service unit comprising at least one passenger service component, a passenger interface and supply adapter (PISA) (10) for controlling said at least one passenger service component independently of an aircraft central control (12), said passenger interface and supply adapter (10) comprising at least one programming input/output (17) for programming said passenger service unit independently of said aircraft central control (12), a signal conductor bus (11) for connecting said passenger interface and supply adapter (10) to said aircraft central control (12), said passenger interface and supply adapter (10) further including a processing unit (14) connected to said programming input/output (17) for individually programming said processing unit (14) and thereby controlling said at least one passenger service component in said passenger service unit independently of said aircraft central control (12), said passenger interface and supply adapter (10) further comprising a memory (15) operatively connected to said programming input/output (17) for program storing, wherein said passenger interface and supply adapter (10) functions as a buffer between said aircraft central control (12) and said passenger service unit, so that said passenger service unit is modifiable by individual programming through said programming input/output without affecting any other passenger service unit or units.
