Sensor wire count reduction system

摘要

A sensor wire count reduction system having various features is disclosed. Signals from multiple sensors may be combined together to reduce the number of wires implemented to convey the signals to a remote location. Multiple binary sensor outputs may be represented on a single wire as a multi-level signal, and may be decoded at a remote location.
