PROBLEM TO BE SOLVED: To quickly and easily check whether connectors, radio sets, etc., are properly connected by wire or radio based on a predetermined correspondence relation for connecting plural devices including plural connectors, radio sets, etc. SOLUTION: An information management circuit 62 manages information representing the identification(ID) of communication control equipment 58, information representing the ID of a connector 18 and information representing the ID of a connector 20, transmits the ID information of the equipment 58 and that of the connector 18 before communication control circuits 64, 66 receive signals or data and outputs the information to connection cables 10, 12 through the connectors 18, 20. At the time of receiving the ID information from the cable 10 through a connector 26, a communication control circuit 70 collates the received ID information with information managed in a connection information management circuit 68 and checks whether the received ID information is the ID information outputted from the connector 18 or not. |
