Abstract
A one wire interface for optical emitter-detectors is disclosed that is fail-safe, simple, and includes diagnostics, noise and static protection. Two indicator lamps are used for diagnostics indicating four conditions; a) Ready, b) Not Connected, c) Blocked Beam, d) No power. This allows single or two conductor systems to have the same troubleshooting information as the 4-wire systems.
