Abstract: Systems and techniques for a lighting control system which include a control switch to control an electrical device are disclosed herein. The control switch includes a master display to display status information of the electrical device. Additionally, a remote control switch couples to provide user-initiated commands to the control switch for controlling the electrical device. The remote control switch includes a display and receive signals from the control switch to display the same status information of the electrical device which enables a user in a location separate from the electrical device to accurately control the electrical device. A second embodiment of the control system may include a unidirectional switch which generates additional control signals that are transmitted to the control switch for control of the electrical device.

Abstract: A control system and method suppress noise in a power-line-based system which has a device repeater connected to an electrical device, and which may be capable of remote control by signals transmitted through the power-line-based system. The control system includes a control device and a communications bus. The communications bus connects the control device to the device repeater. The control device, using a control repeater, controls a phase signal of the device repeater to suppress noise during operation of the electrical device associated with the device repeater.

Abstract: A repeater in a power line control system includes a selective repeat feature. The repeater stores selected codes associated with a particular location. When a command is received on an input power line, the repeater repeats only those commands that have the selected codes. Implementations of the repeater include a test switch that, when activated, send command signals to activate and deactivate electrical devices in the power line communication system. A noise level indicator can be included to indicate a noise level on the input power line that can disable commands transmitted to an electrical device in the power line communication system.

Abstract: An apparatus and method place a node in an unconfigured state, with the apparatus and method functioning within an electrical network including a plurality of such nodes. Each node is adapted to communicate over a communications network. Such electrical networks can be implemented utilizing the CEBus (EIA-600 standard) or LonWorks communications systems. The apparatus and method operate in a LonWorks communications system by placing a node in an unconfigured state for installation or maintenance purposes. A push button switch is in a suitable location in the apparatus to be accessed by a user. The switch is coupled between a service pin of a Neuron chip and ground. Under control of an executable application program, pressing the switch for a predetermined length of time causes the node to be placed in the unconfigured state.
