Abstract: PROBLEM TO BE SOLVED: To provide a method and system for suitably and automatically terminating the mutual connection of various mutual connection systems to a bus. SOLUTION: A cable 12 connected to an adaptor card 10 can be automatically terminated. The existence of a device connected to such a cable 12 is detected. A terminal circuit is selectively started in accordance with a device connected to the card 10 and the terminating operation of the cable 12 is executed. In an embodiment, plural different types of devices having respectively different data length values are connected to a normal adapator card 10 through plural cables 12. These cables 12 regulate the the mutual connection of the devices to the card 10 based upon a bus protocol. A signal to be transmitted/received to/from the cable 12 is sourced/sunk from/into a controller chip. A terminal circuit adjacent to the controller chip 15 selectively started in accordance with the type of a device connected to a bus and termination is presented to the host side of the bus.
