Abstract

PURPOSE: To curtail the cost of cables and construction by collecting the signal lines to one cable, and connecting it one after another, in the connection system of plural terminal equipments and the common control unit.
CONSTITUTION: The exclusive signal lines consisting of 4 lines per set and 12 in total extending from the control unit 1 to plural terminal equipments 21W23 are collected as one cable 11, and it is physically connected one after another to all the terminal equipments 21W23. Each terminal equipment 21W23 is equipped with the connection selective circuit 12, selects a signal line to be exclusively used for its own equipment, in the cable 11, and connects it to the receiving circuit 7 and the transmitting circuit 8. In this way, the control unit 1 and each terminal equipment 21W23 are connected in a star connection electrically, and are connected one after another physically. Accordingly, it is possible to easily select the connection system which is the most suitable for the installation form of the terminal equipments 21W23.
