Title: The most commonly used network application tool line finder

is this thing down here.

It has two functions:

1. Line hunting

2. Survey line

How to find the line:

Suppose this is called the end of the female head, this end is mainly connected to the terminal equipment (desktop, notebook, printer, telephone port, layer 2 terminal switch, etc.), this end is the end that needs to be tested, for example: I found that my laptop can not access the Internet, I need to test whether there is a problem with my network cable? At this time, you only need to plug the network cable into one end of the network interface of the female head, and the other end is assumed to be the male head, that is, one end of the line finder (the network equipment you are looking for: switches, routers, hubs, network extenders, etc.)

Suppose this is called the male head, which is used to find the end of the line, mainly looking for the equipment on the upper end of the terminal equipment.(Layer 2 switches, Layer 2 routers, bridges, etc.), use the female head to open the line selection mode, the male head to open the line measurement mode, adjust the volume of the sound to the maximum, when you hear a clear and crisp sound in the process of line finding, it is the network cable that needs to be inserted. This requires a certain amount of experience. Slowly grope, you will find the line very easily. You need to slowly experience it. The more complex the network environment is, the more troublesome the line finding process is. There is strong electricity. TV set-top box wiring, all kinds of interference, etc., at this time line search requires patience

How to measure lines:

When the line is found, you need to determine whether there is any problem with this network cable. At this time, you need to adjust the equipment mode at the female end to the line measurement mode, and then plug the port that just found the line into your own end. Check the order of the indicator lights. Under normal circumstances, the standard of the network cable is 568B, so the order of the indicator lights is orange white, orange, green white, blue white, green, brown white, brown; This is the normal large line search, the indicator light display is from 1, 2, 3, 4, 5, 6, 7, 8 a light, this is correct, if all light in this order, indicating that both ends of the network are normal, if not, indicating that one end of the network cable is a problem, need to do again, or the whole network cable that place is broken, this is the need to diagnose according to the actual situation, not so difficult.

test cable

Sometimes you need to test whether it is through or not. You can also test it with a line finding tool. One end is connected to the female head and the other end is connected to the male head. According to the standard of 1, 2, 3, 4, 5, 6, 7, 8, there is no problem. This is very simple.

telephone jumper

Sometimes the phone needs jumper, also through the line finder to find the line, and then use the line tool to make the line (telephone module, need to jump more than 100 phones or more, need to use this, this is also a money-saving strategy), if there is a fixed port, then directly plug the telephone interface network cable OK.

What needs attention is: prepare the label, record the phone, jump station, a port, jump to whom, otherwise the phone line will jump frequently, and each time you need to run at both ends, it is more tiring, so try to fix the office station in the early stage, fix the phone, save the trouble of frequent jumpers in the later stage.

Battery use: generally do not use the battery need to buckle down, the battery model is 9V battery, online input microphone battery can find a pile, and then find 9V battery, buy the cheapest on the line, one also does not use much, so do not need too expensive

Summary:

1. Two functions of line-finder: line-finding and line-measuring

2. How to find the line

3. How to measure the line

4. How to jump the phone line

5. Normal lighting sequence of measuring line:1,2,3,4,5,6,7,8

6. What type of battery to buy
