Abstract

PURPOSE:To extend a bus line securely with extremely ease, by controlling efficiently the switching of directions of the bus line of a standard bus to which various equipments are connectable. CONSTITUTION:When a standard interface bus 20A is connected to an extended interface bus 20B via an adapter 21, the adapter 21 has control at either side of the interface buses 20A and 20B, and a function of control over the state of a talker, and bus-direction switching and connection are carried out suitably. Therefore, equipments 241-24n connectable to the interface bus 20B are installed at distances.
