Board jumper connection method secrets

As a newbie, it is not easy to build your own computer from the ground up. Maybe you know where the CPU should be plugged in and where the memory should be plugged in, but when there are lines of complex jumpers, many new users do not know how to start. It is not mysterious to start the key Remember the first time you saw a computer installed, JS inserted CPU, memory, graphics card, and so on into the motherboard, and then pulled out its own key (or just find a screw) from its pocket) when I touch the computer gently on the side of the motherboard, does the computer work? Are you surprised? (I was surprised when I first saw it )! In the face of a brand new main board, JS can connect the patch cord on the main board in one or two minutes without reading any instruction. Do you think he is a master? Well, after reading the article today, you will feel that this is not worth mentioning, and as long as you remember it a little bit, you will be able to fully remember the secret to fix all the jumpers on the motherboard without reading the manual. This is called a real Jumper. First, let's look at a more conceptual problem. In fact, the line of pins on the motherboard that need to be connected is not called a jumper because they cannot reach the Jumper function at all. The real Jumper is two or three pins. There is a small jumper above which should be called a jumper. It can change the hardware settings and frequency; the pins connected to the chassis do not play this role at all, so in the true sense they should be called panel connection pins, but because they are not similar in appearance to jumpers, so we often call them jumper ". After reading this article, connecting to this terminal will make the line very easy. As to who is the first pipe panel connection pin called "jumper", I believe no one can determine. However, since this is what we call it, we are also used to it, so we will not pursue this. So in this article, let's just connect the pipe panel with a pin called a jumper. For better understanding, let's start with the connection lines in the chassis. In general, the connection lines in the chassis all use text to mark the definitions of each connection line, but how to identify these labels is the first problem we need to solve. In fact, these online tags are abbreviated in English and are not hard to remember. Next, let's get to know each other one by one (below each picture is the relevant introduction )! Power Switch: Power SW Full name: Power swicth Possible use names: power, power switch, ON/OFF, Power Setup, PWR, etc. Function Definition: The power-on button before the chassis Reset/restart switch: reset SW Reset swicth Possible use names: reset, reset swicth, reset setup, RST, etc. Function Definition: reset button in front of the chassis Power Indicator: + /- Possible use names: power LED, pled, PWR led, Sys LED, etc. Hard Disk Status Indicator: HDD led Hard Disk Drive Light Emitting Diode Possible Use name: HD led Alert: Speaker Possible Use name: SPK Function Definition: motherboard abnormal working alarm Needless to say, the front USB interface is usually a whole Audio connection line: Audio Possible Use name: FP audio Function Definition: chassis front-end audio After reading the simple text and text, you must have understood the definition of these connections on the chassis. In fact, it is really very simple, just a few very simple abbreviations in English. Next we will come to know the jumper on the motherboard ". In fact, the line on the chassis is not terrible. More than 80% of beginners feel the biggest headache is the definition of jumper on the motherboard, but is it really so terrible? The answer is no! In addition, there are many other rules, that is, because of these rules, we can do the same thing, no matter what brand of motherboard do not need to read the manual to insert a complex jumper. ● Where is the first pin of the Jumper? To learn how to jumper, we must first know where the Jumper starts. This is actually very simple. On the motherboard (the same for any board Device), there is always a thick printed frame at either end of the jumper, And the Jumper should be counted here. After finding the rough printed box, you can choose from left to right, from top to bottom. For example. ● 9pin switch/reset/power supply light/hard drive light Definition This motherboard is the same as the motherboard in the previous figure. It uses 9pin to define the switch, reset, power supply, and hard drive. 9pin switch/reset/power supply light/hard drive light jumper is currently the most popular way, more than 70% of the market brands are using this method, it gradually became a standard, especially the motherboard launched by several major generation plants for Channel vendors. This method is more than 90%. 9-pin panel connection jumper Is 9pin defined switch/reset/power supply light/hard drive light, here you need to note that the 9pin is not defined, therefore, you do not need to insert this jumper. When connecting, you only need to follow the above connection, which is very simple. Among them, the power switches (SW) and the reset switch (both are positive and negative), and the two indicators need to distinguish between the positive and negative, the positive pole is connected to the first needle (that is, the direction of the Printing Line ). Can you tell the positive and negative sides of this line? Also, I almost forgot to mention that it is very easy to distinguish between the positive and negative cables on the chassis. Generally, the colored cables are the positive ends, while the black/white cables are the negative ends (grounded, sometimes indicated by Gnd ). After learning and remembering the content on this page, you can connect to the vast majority of motherboard switches/reset/power indicator/hard drive indicator, now you can unplug this line from your chassis and plug it in again. Remember the arrangement! In order to facilitate your memory, here we will use four sentences to summarize 9pin definition switch/reset/power supply light/hard drive light position: 1. Power Supply plug next to missing needle 2. Reset the Power Supply 3. power plug-in next to the power supply, and the negative pole is close to the power jumper 4. The hard drive light is inserted next to the reset, and the negative pole is near the reset jumper. So, I believe you will remember it! ● Typical connection methods for Asus Motherboard Many of our friends will give priority to the Asus motherboard when installing it. However, the wiring rule of the Asus motherboard is generally different from what we mentioned on the previous page, but it is also very representative, so here we will discuss it separately. It is the wiring of the Asus motherboard (the red dot indicates there is no plug-in), in fact, it is easy to remember. Note that the pled of some chassis is a 3pin plug, but in fact there are only two lines above it. here we need to connect to the 3pin pled plug, such as the dotted line, is dedicated to connecting 3pin pled plug. Let's look at this rule. First, the law of speaker is the most obvious. When we put 4 pin together, we couldn't insert anything except speaker. So when we see this plug-in later, we will first determine the location of the speaker. Then, if there is 3 pin together, it must be connected to the power indicator, because only the power indicator may appear 3 pin; third, the power switch 90% is independent of the two pins in the middle, of course, you can also use the conductor to pin the two pins. If the PIN is turned on, it turns out that it is power-in. The reset next to it can also be tested in the same way. The rest of course is the hard drive light. Note that both the power indicator and the hard drive working status indicator should be divided into positive and negative sides. In fact, there is nothing wrong with the plug-in, but it will not turn on, no damage to the motherboard. ● Other wiring methods of the irregular motherboard: In addition to the above, there are some motherboard wiring rules that are not very obvious, however, these boards are clearly identified next to the wiring except the wiring method (in fact, most of the Boards are identified), and are distinguished by color on the pin base, such. When we encounter such a motherboard, we just need to plug in the line according to the logo. Now, I believe you have understood the secret of using the key to start the installer. In fact, it is very easy to use the power plug-in for transient connection. ● Front USB The wiring method of the front-end USB is actually very simple. Now the general chassis makes the front-end USB wiring into a whole. You just need to find the corresponding plug-in on the motherboard and plug it in together. Generally, the USB Plug-in on the front of the motherboard uses a 9pin connection mode, and there are obvious USB 2.0 labels next to it. It is also very easy to find the pre-USB pin on the motherboard. Currently, the motherboard generally has two or more pre-USB pins (for example ), when you look for the front USB, you only need to see this 9pin, and there are two or more groups of plug-in together, you can basically be sure that this is the front USB plug-in, there will also be an identifier near the motherboard. In general, the front USB connections on the chassis are searched for in this integrated mode. There are eight cables above, namely VCC, Data +, data-, And Gnd, you don't need to talk about this integration. Just plug it in directly. If they are separated, they are generally connected in the red, white, green, and black order. Although this line is integrated, it is also sorted in red, white, green, and black. ● Method for connecting front-end audio Because front-end audios have been popular for nearly two years, let alone users. Even many installed technicians cannot connect to front-end audios, there are even a lot of JS people who say something like this without making such a joke. So is the front-end audio so difficult to connect? Let's take a look. From the current market, we can see that the sorting of the front audio plug-in has become a fixed standard (such ). From the figure, we can see that there are a total of 9 pre-audio pins, But they occupy a total of 10 pin positions, and 8th pins are left blank. It is a typical frontend audio line. In fact, the frontend audio only needs to be connected to seven wires, that is, seven wires. On the pin end of the motherboard, we only need to understand the definition of each pin, and the front audio is well connected. Next let's take a look at the definition of each needle on the motherboard: 1 -- mic in/MIC (microphone input) 2--gnd (grounding) 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 (audio output after sound channel) When connecting the front-end audio, you only need to connect the corresponding line according to the above definition. In fact, the 5pin and 6pin, 9pin, and 10pin are connected by a single wire in some chassis, and the same effect can be achieved. It seems that there are a lot of lines, but it is also very easy to remember, you may wish to follow the instructions I remember. First remember the first three, the first is the microphone input, the second is the ground, the third is the microphone voltage, then the 5pin and 6pin into the right channel, the 9pin and 10pin into the left channel. From top to bottom, mic in, MIC voltage, right channel, left channel, plus a ground. Is it easy to remember this? Many cables are actually integrated, so there is no need to worry about cabling. Well, the content we want to talk about today comes to an end here. As long as you carefully read this article, I believe it will not be troubled by the complicated patch cords on the motherboard in the future. Of course, there may be some other defined jumpers on the motherboard, such as the external 1394 Interface, which all have obvious signs, and basically the connections are integrated. You can simply plug them in directly, it is not difficult. Here we will not talk too much about these few jumpers.
