PROBLEM TO BE SOLVED: To facilitate connection to the home LAN and the public line by giving a prescribed entry server address to a main device having the function of the server of the power line LAN, permitting a new terminal unit to transmit data containing the self-address to the entry server address and permitting the main device to register an entry, based on data. SOLUTION: The main device 2 has the functions of the servers of the power line LAN and the radio LAN and the prescribed entry server address is given to it so that home electric appliances can easily be LAN-connected by a user. The entry server address is common to all the units which can become the main devices and terminal units S1 and S2 can transmit data to the main device without setting anything. When the terminal units S1 and S2 are newly used in the house, the operation of the entry to the LAN, an 'entry key' is depressed, for example. The server of the main device 2 registers the entry of the terminal unit, based on data. |
