  • Lighting control protocol
    Patent number: 8878644
    Abstract: A digital lighting control network protocol with forward and backward frames, each of the frames including an error check code. A no-acknowledgment (NAK) signal is sent from a receiving node to a transmitting node responsive to the error check code. An interface circuit of the receiving node may include an energy storage section to store at least some energy from the network while receiving digital signals, and an output section to transmit digital signals to the network using the stored energy. The interface circuit may also include a high voltage buffer circuit. The transmitting node may send forward frames to receiving nodes based on device type.
    Type: Grant

    Date of Patent: November 4, 2014
    Assignee: Leviton Manufacturing Co., Inc.
