Peripheral device and parallel bus system

摘要

A peripheral device (1, 2, 3) connectable to a controller (100) via a parallel bus (20) at one of a plurality of bus port positions, comprising: at least two connection ports (10, 11) connected to at least two bus lines (10); 20) can be connected according to a bus-connection-position-specific interconnection, the bus-connection-position-specific interconnection permitting a differentiation of the bus connection positions by the peripheral device on the basis of measurable physical quantities transmitted to the peripheral device via the at least two connection lines; a position information acquiring unit (16) configured to measure the physical quantities transmitted by at least two connection terminals of the peripheral device with at least two bus lines and to determine the terminal position therefrom, wherein the at least two bus lines are also used as communication lines of the serve parallel bus.
