A controller that operates using two different processors is provided. Each processor performs certain predetermined functions. A control processor is responsible for switching AC power distribution and control, while a message processors is responsible for messaging. A polling scheme and arbitration logic prevent data transfers relating to these two processors from interfering with each other. A configurable interface allows many different types of appliances to attach to the system, and a serial multimode interface further enhances the configurability of the system.

Control apparatus for use in a dwelling

The present invention uses a logic control to determine which of a plurality of processors receives priority, and generates WAIT signals for the non-selected processor. Further, user configurable pins exist that allow the user to determine the priority that the attached processor will obtain when simultaneous chip selects are transmitted.

A electrical transmission line termination device capable of performing various termination requirements including matching the line impedance of wires in a transmission line with load impedances, electrically connecting conductors in a transmission line for maintaining electrical continuity, detecting improper wiring of the various wires in a transmission line, and connecting a cable shielding conductor to a ground wire.

Electrical transmission cable termination device having short and

The present invention provides two ribbon cable for conducting AC power and digital data signals respectively. A pliable insulating material holds together and electrically insulates the conductors on each ribbon cable. Conductive material, such as a conductive foil or conductive plastic serves to shield the electromagnetic interference generated by the transmitted AC power from the data conductors. The ribbon cables are folded in a protective outer jacket so that the conductive material is disposed substantially between the power conductors and the data conductors. This maximizes the electromagnetic interference shielding of the conductive material.
