Using the Optical Port of the Teridian 71M6511/71M6513


This application note discusses using the optical port of the Teridian 71M6511 (single-phase) and 71M6513 (3-phase) energy-meter ICs. This port is used to communicate with portable devices, and this method of communication is necessary for optical meter-reading, maintenance, or updates. The optical isolation keeps dangerous voltages away from the outside of the meter and maintains the integrity of the meter enclosure. Read full article.
