2. Insert the terminal plugs to be tested into the corresponding ports of the main tester and the remote tester. (Try to keep the plug and socket in good contact. Otherwise, it will affect the scanning result.) If all the line ends of the test line are good; Main tester and remote test. Indicator lights 1, 2, 3, 4, 5, 6, 7, 8, G are flashing one by one. If you test the unshielded wire, the G light of the remote machine will not flash.
The correct wiring is the flashing network cable:
