Test Methods:
1. Test the twisted pairs 1, 2, 3, 4, 5, 6, 7, 8, g one by one (pair) to determine which (pair) is wrong, short circuit or open circuit.
2. The switch is closed, ON is the normal test speed, S is the slow test speed.
3. Twisted pair test: Turn on the power, plug the network cable into the main tester and the remote tester, and the host indicator lights will flash from 1 to g one by one, as shown in the figure below:
Main Tester: 1-2-3-4-5-6-8 - G
Remote Tester: 1-2-3-5-6-7-8-G (RJ45), 1-2-3-4 (RJ11)
If the wiring is not normal, the following will be displayed:
a. When there is a network cable, e.g. Line 3 is broken, the lights of the main test and remote terminal No. 3.
b. When multiple lines are not available, multiple lines will not light up. When the network cable is less than 2 lines connected, the light will not light up.
C. When the two ends of the network cables are out of order, for example, 2, 4 cables are out of order, the display looks like this:
The main tester remains unchanged: 1-2-3-4-5-6-8 - G
The remote terminal is: 1-4-3-2-5-6-8 - G
d. When the network cable has 2 short circuits, the main tester does not light up, and the two wires of the remote terminal show that the short circuit lights are dimly lit. If there are more than 3 wires (including 3 wires), all short circuits will be short-circuited. The lights of multiple line numbers go out.
4. To test the distribution frame and wall-mounted module, two matching jumpers (such as 110p4-RJ45) are required to lead to the tester.
