ABSTRACT:
To connect one out of a plurality of peripheral units to a data bus, each unit is connected to two wires of an address matrix. When a unit wants to connect itself to the data bus, it applies a starting voltage to both wires. The central unit then searches in both matrix coordinates for the two wires of the starting-voltage-transmitting unit and connects the unit so found to the data bus by excitation via the wires.
