Diagram of all secrets of motherboard jumper connection

As a novice, it is not easy to really assemble your own computer from the beginning, perhaps you know where the CPU should be plugged in, where the memory should be inserted, but when encountering a row of complex jumpers, many novice people do not know how to do so. The key is actually not mysterious.

Remember the first time you see a computer, JS will cpu, memory, graphics card and so on the motherboard, and then from the pocket to take out their keys (or casually find a screw) on the side of the motherboard lightly touch, the computer is running up the scene? is not surprised (the first time I saw it was very surprised)! In the face of a brand-new motherboard, JS always do not have to read any instructions, you can in 1, 2 minutes will be the motherboard on the dense jumper connection, is not that he is a master? Hehe, after reading today's article, you will feel that it is not worth mentioning, and as long as you remember a little, you can fully remember, Reach the secret of all jumpers on the motherboard without looking at the instructions.

Steps/Methods

1, this is called the real jumper

First, let's correct a conceptual question, in fact, the row of the motherboard that need to be wired pins are not called "jumpers", because they do not "to the function of jumpers." The real jumper is two/three root cuttings pin, there is a small "jumper" that should be called "jumper", it can play the role of hardware change settings, frequency, etc., and the chassis connected to those pins do not play this role, so in the real sense they should be called panel connection pins, but because and "jumper" There is little difference in appearance, so we often call them "jumpers".

Well, today we are going to say that the content here also to sue a paragraph, as long as seriously read this article, I believe in the future will not be complicated by the motherboard on the jumpers. Of course, there are some other motherboards may have some other definitions of jumpers, such as the external 1394 interface, these are very obvious signs, and basically the connection is integrated, directly plug on it, it is not difficult, and here we do not use the less jumper to do too much to tell

2, after reading this article, connect this a lot of lines will become very easy

As to who the hell is the first tube panel connection pin is called "jumper" people, I believe that no one can be sure. But since all so called, everyone is accustomed to, we also do not pursue these, so in this article, we would like to Pipe panel connection pin called Jumper bar.

To make it easier to understand, let's start with the wiring in the chassis. In general, text is used on the connection lines in the chassis to label each group of connectors, but how to identify them is the first problem we have to solve. In fact, the labels on these lines are abbreviations in the English language and are not difficult to remember. Let's make one of the following (each picture below is related to the introduction)! Power switch: Power SW

English full name: Power swicth

Possible names: Power, Power SWITCH, on/off, Power SETUP, PWR, etc.

function definition: Boot button on front of chassis

3. Reset/restart switch: Reset SW

English Name: Reset swicth

Possible names: RESET, reset swicth, Reset Setup, RST, etc.

function definition: Reset button in front of chassis

4. Power Indicator: +/-

Possible name: POWER led, PLED, PWR led, SYS led, etc.

5. HDD Status indicator: HDD LED

English full name: Hard disk drive Light emitting diode

Possible name: HD LED

6, Alarm: SPEAKER

Possible name: SPK

function definition: motherboard work Abnormal alarm

7, this needless to say, connect the front USB interface, is generally a whole

8. Audio Cable:

Possible name: FP AUDIO

Feature definition: Chassis front-facing audio

After reading the above simple graphic introduction, we must already know the chassis on the definition of these lines, in fact, is really very simple, is a few very simple English abbreviation. Next we are here to meet the "jumpers" on the motherboard.

In fact, the line on the chassis is not scary, more than 80% of beginners feel the most headache is the definition of jumpers on the motherboard, but in fact really so scary? And there are a lot of laws, that is because of these laws, we can do extrapolate, No matter what brand of motherboard do not have to read the manual plug the complex jumper.

Where is the first pin of the jumper?

9, to learn how to jumper, we must first understand where the number of jumpers to start, this is actually very simple. On the motherboard (as with any board device), there will always be a thicker print frame on either end of the jumper, and the jumper should count from here. After finding the thicker print box, just follow the number of principles from left to right, top to bottom. As shown above.

9Pin switch/reset/power light/HDD Light definition

10, the motherboard and the previous diagram of the motherboard, are using 9Pin definition switch/reset/power light/hard drive light

9Pin switch/reset/power light/hard drive light jumper is one of the most popular way, the market more than 70% of the brand is the use of this way, slowly become a standard, especially the major generations of factories for the channel manufacturers introduced motherboards, the use of this way is up to 90%.

11, 9-pin panel connection jumper schematic

The figure above is a schematic diagram of the 9Pin definition switch/reset/power light/hard drive light, where it is important to note that the 9Pin is not defined, so it is not necessary to plug in the jumper. When connecting, just follow the schematic diagram above to connect it, very simple. Among them, the power switch (Power SW) and the reset switch (both are non-positive and negative), and two LEDs need to distinguish between positive and negative, the positive is connected to the direction of the first pin (that is, the direction of printing thick lines).

Can you tell the difference between the positive and negative poles of this line?

And a little bit forgot to say that the line on the chassis is very simple to distinguish between positive and negative, generally colored lines are positive, while black/white lines are negative (grounded, sometimes with GND).

After learning and remembering the contents of this page, you will be able to handle most of the motherboard's switch/reset/power indicator/Hard drive LED connection, now you can remove this part of your chassis, and then plug it in. Be sure to remember the arrangement! In order to facilitate the memory, here we use 4 words to summarize 9Pin definition switch/reset/power light/Hard drive light location:

1, missing needle side plug Power

2, power supply opposite plug Reset

3, Power side plug power lamp, the cathode near the power jumper

4, reset next to the hard drive light, negative near the reset jumper

Say so, believe you must remember!

Representative ASUS Motherboard Wiring Method

Many friends will give priority to ASUS motherboard, but ASUS motherboard wiring rules generally and the previous page we talked about not the same, but also very representative, so we are here to give a separate to discuss.

The diagram above is a schematic diagram of the ASUS motherboard (Red dots indicate no pins), which is actually very well remembered. Note here is that some of the chassis pled is a 3Pin cable plug, but in fact there are only two lines, where you need to connect to the 3Pin pled pin, as shown in the dotted line above, is specifically connected to 3Pin pled plug.

Let's find out the pattern of this. First of all, the Speaker law is most obvious, 4Pin together, in addition to plug speaker nothing else can not plug. So when we see this pin in the future, we first determine the position of the speaker. Then, if there is 3Pin together, it is necessary to connect the power indicator light, because only the power supply indicator may appear 3Pin; third, the power switch 90% is independent in the middle of the two pin, of course, you can also use the conductor to short pick up the two pin, if the boot, it proves that plug power, The next reset can also be tested in the same way. The rest of course is plugged into the hard drive light, note that the power indicator and hard disk work status indicators are to be positive and negative, actually plug the reverse is nothing, but will not light, will not damage the motherboard.

Other non-regular motherboard wiring method:

In addition to the previous we talked about, there are some motherboard wiring rules are not too obvious, but these boards are clearly located next to the wiring in addition to the method of wiring (in fact, most of the motherboard are identified), and in the pin base color to distinguish, as shown above. When you encounter such a motherboard, you can follow the logo to plug the line.

See now, I believe you already understand the installation of the key to boot the secret, it is actually power corresponding PIN for short, very simple.

Front-facing USB

Front usb Wiring method is actually very simple, now the general chassis will be the front USB wiring made a whole, we just find the appropriate pin on the motherboard, together plug on it. In general, the current motherboard USB pins are used in the 9Pin wiring, and there are obvious USB 2.0 logo.

To find the front USB pin on the motherboard is also very simple, now the motherboard generally have two or even more than two sets of front usb pin (pictured above), looking for the front usb when everyone just see this 9pin, and there are two groups/two sets of pins together, Basically you can be sure that this is the PIN for the front USB and it will be identified near the motherboard.

Now general chassis on the front USB connection search is such an integrated type, the above a total of 8 lines, respectively, is VCC, data+, data-, GND, this integration will not have to say, directly plug on the line. If it is separate, under normal circumstances are in red, white, green, black in the order of connection. As shown above, this line, though integrated, is also sorted in red, white, green and black.

Front-facing audio connection method

Because the front-end audio is almost two years before the popular, not to mention that the user, and even a lot of installed technicians are not too likely to connect the front audio line, and even many JS directly said that after the front of the back will not make a noise such jokes. So the front audio is not so difficult to pick up, let's have a look.

From the current market on the motherboard, the pre-placed audio pin sequencing has become a fixed standard (pictured above). As can be seen from the figure, the front audio pin has a total of 9, but altogether occupies 10 root cuttings pin position, the 8th pin is left blank.

The figure above is a typical line of front audio, with the front-facing audio actually connecting only 7 lines, which is the 7 lines in the figure above. At the pin end of the motherboard, we just need to know the definition of each root cuttings pin, and it's good to connect the front audio. Let's look at the definition of each pin on the motherboard:

1--mic in/mic (Microphone input)

2--GND (grounded)

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 (do channel back audio output)

When connecting the front audio, just follow the definition above to connect the corresponding line. In fact, sections 5Pin and 6Pin, 9Pin and 10Pin are connected by a wire on some chassis and can achieve the same effect.

Looks like a little bit more, but also very good to remember, you may wish to follow the author remember the method. First of all, remember the top three, the first is the mic input, the second grounding, the third is the microphone voltage, and then the 5Pin and 6Pin plug the right channel, 9Pin and 10Pin to insert the left channel. From the top down the number is, mic in, mic voltage, right channel, left channel, plus a ground. Isn't it easy to remember?

A lot of wiring is actually integrated, no more trouble with the line sequence
