Abstract
A networked suite of aircraft-seat devices is disclosed, wherein the devices receive both power and network communications via the same terminal. The devices may be connected by a two-wire connection and may be configured in a daisy chain. Various aircraft seat devices, such as actuators, may be directly connected to the network or connected via control modules connected to the network. One device on the network may be designated as a master device for controlling network configuration. A method of automatically addressing network devices includes measuring a first quiescent current through the network, enabling an addressing current in unaddressed devices, and measuring the change in current at each device after enabling the addressing currents to determine the last device in the chain.
