A communication device that establishes a communication with another communication device and supplies electric power to the other communication device by way of a transmission channel, the device comprises a supply voltage generation section that generates a supply voltage, a first detection section that detects a connection of an electric device other than the other communication device to the transmission channel, and an output control section that controls a supply of electric power to the other communication device, wherein the output control section supplies no power to the other communication device when the first detection section detects the connection of the electric device.

Communication device, power supplying method therefor, and power supply system

A communication apparatus has a electrical outlet that is electrically connected to a power connector so as to supply power externally; a connection detector that detects connection of an external plug to the electrical outlet; and a controller that uses a receiver and a transmitter so as to perform setting with a device connected to the electrical outlet, when external connection is detected at the electrical outlet.

Communication apparatus, communication system, image capture apparatus, video capture apparatus, and setting method thereof

A terminating device enables power line communication to be performed while suppressing degradation of the communication quality without decreasing the communication efficiency. The terminating device includes power supply plugs, a terminating circuit, a changeover switch, and power jack terminals, which are housed in an adapter case. The terminating circuit has an impedance corresponding to the impedance between power lines in the used frequency band of power line communication and is connected or disconnected between the power supply plugs by the changeover switch.
