Abstract
A method of programming one or more relay based electrical devices comprises the steps of selecting an electrical device to program, switching the relay from a first state to a second state, and applying a time varying signal to the relay associated with the selected device. The method also includes the steps of counting signal transitions occurring during the switching of the relay, and comparing the counted signal transitions to a predetermined value. The method further includes the step of programming the device based on the comparison step. Accordingly, the programming methodology advantageously enables programming of the device by employing the switching time period of the relay which allows for elimination of a separate dedicated programming terminal.
