1. An aircraft cabin module, comprising:
- (a) a connection plug for connecting a cable having at least one electric data line and a sheath for electromagnetic shielding;
(b) an isolating circuit for isolating a data signal from a direct supply voltage transmitted via the electric data line, the isolating circuit comprising two isolating transformers connected via a throttle for signal suppression to the connection plug, wherein the direct supply voltage and the data signal are additively superimposed on the direct supply voltage and are transmitted via the electric data line of the cable, and wherein the direct supply voltage is switchable over between various voltage levels; and
(c) a decoding/coding unit for connecting to an aircraft server.

Abstract
System and method for the voltage supply of aircraft cabin modules (1). An electric supply voltage and an additive data signal are transmitted via a cable (3). The aircraft cabin modules (1) have a connection plug (2) for plugging onto the cable (3) and an isolating circuit (5), which isolates the transmitted supply voltage from the data signal.

16. A method for the voltage supply of at least one aircraft cabin module comprising the steps of:
-
additively superimposing a data signal on a direct supply voltage received by the aircraft cabin module via an electric data line of a cable having electromagnetic shielding; separating the direct supply voltage from the superimposed data signal in a decoding/coding unit; and switching the direct supply voltage via two isolating transformers connected via a throttle for signal suppression to the connection plug over between various voltage levels. - View Dependent Claims (17)
