Abstract
An aircraft in-flight entertainment system includes a plurality of seat electronic boxes (SEBs) spaced throughout the aircraft. Each SEB is configurable for passing a registration token along to an adjacent SEB. Cabling connects the SEBs together in a daisy chain configuration. Registration circuitry is connected to the cabling for identifying a location of each SEB based upon passing of the registration token among the plurality of SEBs.
