Abstract

PURPOSE:To reduce number of check personnel, to decrease the checking time and to improve the reliability and efficiency of wiring of a home bus by controlling a checking device having a part generating a voltage between terminals of an information receptacle and a checking device having a part connecting to other information receptacle and sensing whether or not a current flows by means of a radio wave or an infrared-ray transmission. CONSTITUTION:When information receptacles of a home bus are connected to checking devices 1, 2 and a start SW of an operation display section 18 is depressed, it is confirmed that a voltage is generated between terminals 1 and 2 of an 8-pin modular connector 11 for twisted pair cable of the checking device 1 and no voltage is generated between other terminals. The changeover of voltage generating position of the checking device 1 is controlled by using a radio wave from the checking device 2. Thus, checking is implemented by one person thereby reducing the number of checking personnel.
