Abstract

PURPOSE:To secure normal transfer operation between two equipment groups by providing a serial-number collating circuit in a connecting device, and collating the serial number of an equipment in the 2nd group sent from an equipment in the 1st group with serial numbers in the connecting device. CONSTITUTION:For example, when an equipment A1 in the the 1st group is connected to an equipment Bm in the 2nd group, the equipment A1 sends the serial number of the equipment Bm to the equipment coordinate part C1 of a connecting devie 1. The part C1 sends a connection request from a decoder 3 to a decoder responding part Dm for the serial number of the equipment Bm. The serial number collating circuit 6 of the Dm collates the serial number Bm sent the equipment A1 with its own serial number and, when the result shows coincidence, sends a normalcy signal from the Dm to the equipment A1 to connect a switch 1m. When both are not coincident, a fault signal is sent out.
