ABSTRACT:
A system for assigning unique addresses to a series of electronic units in an in-flight entertainment system. The electronic units are connected via an interconnect bus and a keyline wire. During initialization of the system, each electronic unit is enabled via the keyline. After an electronic unit is enabled, the interconnect bus transfers a unique address to the electronic unit and instructs it to ignore future address write signals. This procedure is repeated for each electronic unit in the series of electronic units. The procedure terminates when the last electronic unit requiring an address has been assigned an address.
