Abstract
A method and apparatus for monitoring and testing the operation and configuration of a remote receiver in an electrical load management system. The receivers are responsive to encoded command signals to remove electrical loads from the electrical distribution system. Upon receipt of a predetermined status inquiry command signal, the receiver retrieves status information pertaining to the receiver, and transmits the status information over a data communications link to a hand-held operator display unit. The operator display unit employs a short-range FM transmitter to transmit the predetermined status inquiry command signal, receives the transmitted status information, and displays the received status information to the operator on a display.
