Your current location: Xinfeng Network Management Home >> Technical Information >> Software and Hardware >> Tutorial Text [Pictures] Revealing the motherboard jumper connection method Graphical explanation Author: Anonymous Tutorial source: Original number of clicks on this site: 66 Update time: 2008-12-10 Font: As a novice, Xiaoda, it is not easy to actually assemble your own computer from scratch. Maybe you know where the CPU should be plugged in and where the memory should be plugged in, but when faced with rows of complicated jumpers, many novices don’t know how. Take action.

Key turning on the computer is actually not mysterious

Do you still remember the first time you saw the computer being installed? JS plugged the CPU, memory, graphics card, etc. into the motherboard, and then from Take out your key (or just find a screw) from your pocket and lightly touch it on the side of the motherboard, and the computer will start running? Are you surprised? (The author was surprised when I saw it for the first time anyway)! When faced with a brand new motherboard, JS can always connect the densely packed jumpers on the motherboard within 1 or 2 minutes without reading any instructions. Do you think he is a master? Haha, after reading today's article, you will feel that this is not worth mentioning, and as long as you memorize it a little, you can completely remember it and achieve the secret of getting all the jumpers on the motherboard without reading the manual.

This is called a real jumper

First of all, let’s correct a conceptual problem. In fact, the rows of pins that need to be connected on the motherboard are not called “jumpers.” ", because they simply cannot achieve the function of a jumper. The real jumper is two/three pins with a small "jumper pop-up" on it. It should be called a "jumper", and it can function. The function of the hardware is to change settings, frequency, etc.; and the pins connected to the chassis cannot play this role at all, so in the true sense they should be called panel connection pins, but they are not the same as "jumpers" in appearance. Large, so we often call them "jumpers"

After reading this article, it will become very easy to connect this large number of wires

As for who is the first. I don’t think anyone can be sure who once called the panel connection pins “jumpers.” However, since it is called that and everyone is used to it, we won’t pursue it, so in this article, we will just deal with the panel. The connecting pins are called jumpers.

To make it easier to understand, let’s start with the connecting wires in the chassis. Generally speaking, the connecting wires in the chassis use words to identify each group of connections. The definitions of lines are marked, but how to identify these marks is the first problem we have to solve. In fact, the marks on these lines are all related English abbreviations, which are not difficult to remember.

Let’s get to know each one one by one (below each picture is a relevant introduction)!

Power switch: POWER SW

Full English name: Power Switch

Possible names: POWER, POWER SWITCH, ON/OFF, POWER SETUP, PWR, etc.< /p>

Function definition: Power button on the front of the chassis

Reset/restart switch: RESET SW

Full English name: Reset Swicth

Possible names : RESET, Reset Swicth, Reset Setup, RST, etc.

Function definition: Reset button on the front of the chassis

Power indicator light: +/-

Possible names : POWER LED, PLED, PWR LED, SYS LED, etc.

Hard disk status indicator: HDD LED

English full name: Hard disk drive light emitting diode

Possibly Name: HD LED

Alarm: SPEAKER

Possible name: SPK

Function definition: Motherboard abnormality alarm

Needless to say, the front USB interface is usually connected as a whole

Audio connection cable: AUDIO

Possible name: FP AUDIO

Function definition : Chassis front audio

After reading the above simple graphic introduction, you must already know the definitions of these connections on the chassis. In fact, it is really simple, just a few very, very simple English abbreviation. On the next page we will learn about the "jumpers" on the motherboard.

In fact, the lines on the chassis are not terrible. More than 80% of beginners find the most troublesome thing is the definition of jumpers on the motherboard, but are they really that terrible? The answer is no! And there are many rules among them. It is because of these rules that we can draw inferences from one example to other cases. No matter what brand of motherboard, there is no need to read the manual and insert complicated jumpers.

● Where is the first pin of the jumper?

To learn how to jump wires, we must first understand where to start counting jumpers. This is actually very simple. On the motherboard (the same as any board device), there will always be a thicker printed frame at one end of the jumper, and the jumper should be counted from here. After finding this thicker printing frame, just count it from left to right and top to bottom. As shown above.

● 9Pin switch/reset/power light/hard disk light definition

This motherboard is the same as the motherboard in the previous picture, both use 9Pin to define switch/reset/power light/hard disk Light

9Pin switch/reset/power light/hard disk light jumper is currently the most popular method. More than 70% of brands on the market use this method. Slowly, It has become a standard, especially for motherboards launched by several major foundries for channel manufacturers. More than 90% of them adopt this method.

9-pin panel connection jumper schematic

The above picture is a schematic diagram of 9Pin defining switch/reset/power light/hard disk light. It should be noted here that the 9th Pin does not Definition, so you don’t need to plug in this one when plugging in the jumper. When connecting, you only need to connect according to the diagram above, it is very simple. Among them, the power switch (Power SW) and the reset switch (both have no distinction between positive and negative poles), and the two indicator lights need to distinguish between positive and negative poles. The positive pole is connected in the direction close to the first pin (that is, the one with printed thick lines). direction).

Can you distinguish the positive and negative poles of this wire?

One more thing I almost forgot to mention is that it is very simple to distinguish the positive and negative poles of the wires on the chassis. Generally speaking, the colored wires are positive, and the black/white wires are negative (ground, sometimes used GND indicates).

After learning and remembering the content on this page, you will be able to connect most of the motherboard’s switches/resets/power indicators/hard drive indicators. Now you can connect these in your case. Unplug some of the wires and plug them in again.

Be sure to remember the arrangement! In order to facilitate everyone's memory, here we use 4 sentences to summarize the 9Pin definition switch/reset/power light/hard disk light position:

1. Plug the power supply next to the missing pin

2. Power supply Plug the reset lamp on the opposite side

3. Plug the power light next to the power supply, with the negative pole close to the power jumper

4. Plug the hard drive light next to reset, with the negative pole close to the reset jumper

Having said that, I believe you must remember it!

● Representative ASUS motherboard wiring methods

Many friends will give priority to ASUS motherboards when installing their computers, but the wiring rules of ASUS motherboards are generally the same as what we mentioned on the previous page They are different, but they are also very representative, so we will talk about them separately here.

The picture above is a schematic diagram of the wiring of the ASUS motherboard (the red dots indicate no pins), which is actually easy to remember. What should be noted here is that the PLED of some chassis has a 3Pin plug, but in fact there are only two wires on it. It needs to be connected to the 3Pin PLED pin. As shown in the dotted line in the picture above, it is specifically connected to the 3Pin PLED plug. .

Let’s look at the rules of this. First of all, the rule of SPEAKER is the most obvious. With 4 pins together, nothing else can be plugged in except Speaker. So when we see this kind of pin in the future, we first determine the position of the Speaker. Then, if there are 3 pins together, they must be connected to the power indicator light, because only the power indicator light may have 3 pins; thirdly, 90% of the power switches are two independent pins in the middle. Of course, you can also use your own conductor short Connect these two pins. If it is turned on, it proves that POWER is plugged in. The Reset next to it can also be tested in the same way. Of course, the remaining thing is to plug in the hard disk light. Note that the power indicator light and the hard disk working status indicator light must be divided into positive and negative poles. In fact, it doesn't matter if they are plugged in backwards, it will just not light up and will not cause damage to the motherboard.

● Other irregular motherboard wiring methods:

In addition to what we mentioned earlier, there are some motherboards whose wiring patterns are not very obvious, but these motherboards are all next to the wiring. The obvious markings are in addition to the wiring method (in fact, most motherboards have markings), and they are distinguished by color on the pin base, as shown in the picture above. When you encounter a motherboard like this, just plug in the wires according to the logo.

Seeing now, I believe you have understood the secret of the installer using the key to turn on the computer. In fact, it means shorting the corresponding pins of POWER, which is very simple.

●Front USB

The wiring method of front USB is actually very simple. Nowadays, the general chassis has the front USB wiring integrated into a whole. You only need to connect it to the motherboard Find the corresponding pins and plug them in together. Generally speaking, the front USB pins on the motherboard currently use 9-Pin wiring, and there is an obvious USB 2.0 logo next to it.

It is also very simple to find the front USB pins on the motherboard. Today’s motherboards generally have two or more sets of front USB pins (as shown in the picture above). Find the front USB pins. As long as you see this 9-pin type, and there are two/more than two groups of pins together, you can basically be sure that this is the front USB pin, and there will be a mark near the motherboard.

Nowadays, the front USB connection on the general chassis is integrated like this. There are 8 wires on the top, which are VCC, Data+, Data-, and GND. This kind of integration is No need to say more, just plug it in. If they are separated, they are usually connected in the order of red, white, green and black. As shown in the picture above, although the line is integrated, it is also ordered in red, white, green and black.

●Front audio connection method

Since front audio has only become popular in the past two years, not to mention users, even many technicians who install the machine do not know how to do it. When it comes to connecting the front audio cable, many JSs even directly joked that there would be no sound after connecting the front audio cable. So is it so difficult to access front-end audio? Let’s take a look.

Judging from the motherboards currently on the market, the ordering of front audio pins has become a fixed standard (as shown above).

As can be seen from the picture, there are 9 pins for the front audio, but one occupies the position of 10 pins, and the 8th pin is left blank.

Click to enlarge

The picture above is a typical front audio connection. In fact, the front audio only needs to connect 7 wires at a time, which is what is shown in the picture above. of 7 wires. On the pin side of the motherboard, as long as we understand the definition of each pin, we can easily connect the front audio. Let’s take a look at the definition of each pin on the motherboard:

1——Mic in/MIC (microphone input)

2——GND (ground)

< p>3——Mic Power/Mic VCC/MIC BIAS (microphone voltage)

4——No pin

5——LINE OUT FR (right channel front audio output )

6——LINE OUT RR (right channel rear audio output)

7——NO pin

8——NO pin

9——LINE OUT FL (left channel front audio output)

10——LINE OUT RL (left channel rear audio output)

Connect When using front audio, you only need to follow the definition above and connect the corresponding cables. In fact, the 5th and 6th pins, and the 9th and 10th pins are connected by one wire on some chassis, which can achieve the same effect.

It seems like there are a lot of lines, but it is also very easy to remember. You may wish to follow the author’s method of remembering. First, remember the first three wires. The first wire is the microphone input, the second wire is grounded, and the third wire is the microphone voltage. Then the 5th and 6th pins are plugged into the right channel, and the 9th and 10th pins are plugged into the left channel. Counting from top to bottom, they are Mic in, Mic voltage, right channel, left channel, and a ground. Isn’t it easy to remember this?

A lot of wiring is actually integrated, so you don’t have to worry about the line sequence anymore

Well, what we are going to talk about today comes to an end here, as long as you are serious After reading this article, I believe that you will not be troubled by complicated jumpers on the motherboard in the future. Of course, there may be some other defined jumpers on some motherboards, such as the external 1394 interface. These have obvious signs, and basically the connections are integrated. You can just plug them in. It is not difficult. , here we will not say too much about these less used jumpers.
