ABSTRACT:
A field configuration terminal is provided that does not require physical or electrical connection to a remote device of a power line communication system. A toroid is provided that comprises a multiplicity of turns of a conductor that is connected in electrical communication with an amplifier and receiver circuitry within the field configuration terminal. A battery, with associated power supply components, provides a direct current source for the microprocessor and logic of the field configuration terminal and for the amplifier thereof. The toroid of the field configuration terminal is shaped to be disposed around a load management terminal of a power line communication system without physical or electrical contact therewith. Signals are transmitted to and received from the load management terminal by inductively coupling the toroid with the load management terminal in signal communication.
