<p>The system has a connecting box (3) with B-side connectors (CNB(1-4)) that are connected with a ground control circuit (50), and A-side connectors (CNA(1-4)) that are connected with input and output devices. Switching devices (20, 21) are arranged between two B-side connectors (CNB(1-2)) and two A-side connectors (CNA(1-2)). A switching control device (57) controls the switching device for changing the connection of the B-side connectors with the A-side connectors according to the input and output devices to be connected with the A-side connectors.</p> |
