And a scanning detector for detecting the voltage.

[0007]

When the connectors at both ends of the communication cable are respectively connected to the adapter and a predetermined operation is performed, a predetermined voltage is applied to each cable wire of the communication cable through the one adapter and the connector connected thereto by the one voltage applying section. Is applied. At the same time, the other scanning detection unit scans each cable line of the communication cable through the other adapter and the connector connected to the other adapter to detect the voltage,
The conduction state of each cable line of the communication cable and the connection state of the other connector are stored in the memory. After that, a predetermined voltage is applied to each cable wire of the communication cable through the other adapter and the connector connected thereto by the other voltage applying section, and one scanning detecting section detects the one adapter and the connector connected thereto. The male pin is scanned to detect the voltage, and the connection state of one connector is stored in the memory. The continuity data of the communication cable and the connection data of both connectors stored in the memory are displayed on the display unit. Further, by a predetermined operation, the data stored in the memory is read out by the printout processing unit and printed out by the printer, and the conduction state and the connection state of the connector displayed by the display unit are printed on the paper surface.

Therefore, by connecting both connectors of the communication cable to the adapter and performing a predetermined operation,
Continuity of communication cables and connection of both connectors are displayed or printed out on the display, so unlike the conventional case where cable cables are checked one by one, it is necessary to check the continuity and connection of communication cables.
