ABSTRACT:
A multi-drop type bus line system having a plurality of terminals respectively connected to a common bus line, in which each terminal has a connector interconnecting with the other terminals and the connectors at the respective terminals are interconnected by means of a connection cable. Each connector is provided with a switch which is actuated each time the connection cable is coupled to the connector of the terminal, whereby when the connection cable is coupled to the connector, the switch releases an impedance matching resistor connected between predetermined terminal pins of the connector. Impedance matching is improved and standing waves are reduced.
