Abstract
In a serial bus network, an environment is provided, in which the serial bus is divided to two local buses and a specific terminal connected to one of the local buses can reliably occupy other terminals connected to the other local bus without influence on the terminals connected to the local buses. A specific terminal is connected to a local bus, to which an inner portalis connected, and an ID information thereof is preliminarily recorded in a ROM. After a power source is turned on, the specific terminal connected to the side of the inner portalis detected according to the ID information from the ROM. An ID information of all of nodes connected to a local bus, to which an outer portalis connected, is read out and stored in a control portion. A bus reset is generated on the local bus. In order to give a connection information of the local bus, a self-ID packet is generated by the control portionand transmits it through a dedicated PHY
