PROBLEM TO BE SOLVED: To enable confirmation work without distributing personnel on the equipment body side, at the necessity of confirming the core wire connection of an intermediate cable before electric conduction, in such a case that the equipment body is remote from an operation room.SOLUTION: Relay interfaces RI1, RI2 are connected to the plugs at of both ends of an intermediate cable CC. The line of each core wire is divided into four, i.e. A, B, C and D. Two wires A, B are connected to a communication line, whereas two wires C, D are connected to a measurement circuit. By switching a relay of each line on and off by personal computers PC1, PC2, conduction check and insulation check are performed for each core wire. |
