Abstract

The device provides a signal to an electronic appliance and is used in a system including a plurality of electronic appliances connected in series so that they can transmit and receive information and control signals amongst each other, with the transmission and reception of the information signals being controlled by a control apparatus. The system includes a preceding apparatus and a succeeding apparatus connected in series with the preceding apparatus. The device includes a first terminal that transmits and receives information and control signals to and from the preceding apparatus, and a second terminal that transmits and receives information and control signals to and from the succeeding apparatus. The second terminal also receives a predetermined control signal from the succeeding apparatus. The predetermined control signal indicates whether the succeeding apparatus is connected to a terminal of the preceding apparatus. The device also includes a switching unit and a processor.
