Font size: much of the small. .
Each time you get a new chassis for profiling, always in on these interfaces to spend some time, because the author's hand compared to the rough so plug it is hard, harder that it is most important is messy thread does not know how to plug in.
Do not bother to look at the book reading out the data cable to the motherboard look before reading confessed, not afraid of you afraid you insert the wrong USB interface board has received the 1394 interface, it will burn as long as a power your motherboard, so be careful. .
■ Understanding jumper and interfaces.
Next, we must allow many users to install the wiring of the headaches. Let's take everyone to know the following to insert the line. Generally inserted in the line of the start, restart, power light, hard work lights, front USB ports and front audio interface. .
The left is the front USB connector, the right is the front panel audio interface.
Chassis switch, and light interfaces. .
The white part is a start, restart, power led, HDD work lights, PIN.
A series of interfaces. .
Here we recognize the following wiring interface, the interface is above white start, restart, power led, HDD work lights, pin; the following, from left to right, green is the front panel audio, green-blue is the COM interface, red is the IEEE1394 interface, two blue is a front USB interface.
Installed Tips: Be sure to refer to motherboard manual for each board, the chassis jumper installation is different, incorrect installation make motherboard burn out does not work. .
Jumper name and role.
POWER SW power switch, the switch control computer, is generally two-pin, no positive or negative. .
RESET SW restart switch, control of the computer to restart, there is no positive.
HDD LED hard work instructions, display hard working state, with positive and negative, then backwards is off. .
The power switch on the POWER LED indicator shows the computer has power, typically green and white, there are positive and negative, connected backwards is not lit.
SPEAK is a speaker, there are positive and negative, then no alarm against the motherboard connection pins each have a letter where the control can be installed, if not the letter, the next designated a diagram. .
The chassis of the line generally darker as the cathode, talking to negative front USB connection cable for red and green and black, the interface on the motherboard to 9-pin, 4-pin plug to a group, the following five-pin front four-pin and as above, the last needle is empty.
■ introductory chapter reset switch (reset button): feet of. This switch is connected to the plug labeled RESET SW general words, while the corresponding location of the pins on the motherboard near the common abbreviation for the RESET, RST, RS, or RE and so on. Regardless of positive and negative, inserted backwards just as effective. .
Power light: Wired is a two-pin plugs, one connection, typically used green indicates another line to white. When a host power starts, the power light will light up. This switch wiring plug of the POWER on LED labeled with the words, but the corresponding location on the motherboard of pins, near the English abbreviation for PW LED, Power LED, PWR LED or PLED + and PLED-etc. Connected backwards is off, come on line.
Hard light: to connect the hard disk light is pin plugs, two connections are usually a red one white. When the hard disk read and write action, the hard disk light will light up. This switch is connected to the plug labeled HDD LED general words, while the corresponding location of the pins on the motherboard near the common abbreviation for the HDD LED, HD, or IDE_LED + and IDE_LDE-so. Had not received anti-light, the change over the line. .
Horn: this connection plug has four pin, but only two lines, its color is a black or red orange one is black and is correctly connected to the chassis of the Horn. This switch wiring the plug and the motherboard on the corresponding pin near generally marked with a Speaker. Some of the computer after the good start would be through the horn "di", or does not start properly, through the Horn corresponding alarm sound for the user to resolve the issue. However, some have been integrated on the motherboard, then you won't have to loudspeaker chassis on the Horn.
Front USB all wiring definition. Red line: positive power supply (connection on the logo for the: +5 V or VCC), white line: negative voltage data line (identified as: Data-or USB Port -), green line: positive voltage data line (identified as: Data + or USB Port +), black line: ground (identified as: GROUND). .
Although the brand motherboard expansion of USB pin definitions vary, but there are several types and wiring methods:.
Category: 8-pin type. .
The type of the PIN number is the 1999 produced before the Board, but so far few P4 (low-grade) motherboard has type of pins. Typically connection method: red line insert a USB pin 1 and pin 2, and the remaining wiring by Port Data-, +, the remainder of the GROUND the order were inserted USB pins, the second connection method is the second set of USB connection and the first group of wiring is really good contrast.
II: 9-pin type. .
The type of USB PIN number for the nearest new motherboard, prevalent support Pentium 4 or Athlon XP chipset motherboards (i845D, i845E, SiS 650 i845D, etc.), especially support USB2. .0 motherboard. The type of USB pin wiring is more unified, common to the majority of the Board.
The third type: 10 pin type. .
Use the PIN number of the type of product, with the i815 i815E, KT133 chipset i815EP, etc, of the earlier two types to chaos. It is recommended that you refer to the manual of the motherboard model number labeled on the connection.
■ Front USB and audio description. .
Chassis front USB/audio cable to the motherboard to connect to some novice it is difficult to know as soon as the wiring in an error, you cannot use the USB and audio device to a USB device or system board burn-out.
Chassis Front USB / audio cable to connect the motherboard, there are some difficulties for some newcomers, to know when wiring errors, ranging from not using the USB and audio equipment, while in USB device or motherboard burned. .
Chassis front panel USB connector is defined.
Let's first look at each case on the front USB connection definition. Typically, the red line: positive power supply (connection on the logo for the: +5 V or VCC), white line: negative voltage data line (identified as: Data-or USB Port -), green line: positive voltage data line (identity To: Data +, or USB Port +), black line: ground (identified as: GROUND or GND).Some chassis manufacturers based on their own craft design requirements, signal line colors as described above, and taking into account the convenience of connecting with the motherboard, accuracy, versatility, chassis manufacturers will do a module USB cable (such as Galaxy 5GNO1, 5GNO2, chassis, B01, Jia Tian Lite-OnG525E chassis 5208 chassis, etc.), some chassis manufacturers take into account the USB cable from the motherboard connection versatility, the signal line dispersion and each signal line as to identity (such as the love of the unique chassis, Foxconn chassis, yongyang YY5601 chassis, etc.), so in order to accommodate many types of USB interface (below) . But no matter how the case of the USB cable definition, as long as the motherboard front USB interface to understand each needle is defined, it would not USB lines are wrong! . .
The definition of the motherboard USB pins.
Next, look at the motherboard's USB pin definitions, although the expansion of the brand motherboard USB pin definitions vary, but no more than the following major types and wiring methods:. .
First class: 8-pin type.
The type of pin is produced before 1999, used motherboards, but now a small number of P4 level (low) motherboard which uses this type of pin. Usually Wiring Method: Insert the USB pin 1 and red pin 2, the remaining cable by Data-, Data +, GROUND sequence were inserted into the remaining USB pins (see Figure 1), the second wiring is just the opposite with the first group of wiring (see Figure 2). .
。.
II: 9-pin type. .
The type of USB PIN number for the nearest new motherboard, prevalent support Pentium 4 or Athlon XP chipset motherboards (I845D, I845E, SiS 650, I865PE, VIA P4M266/A, VIA P4X266/E, VIA P4X400, etc.), especially support USB2. .0 motherboard. The type of USB pin wiring is more unified, common to the majority of the Board.
. .
The third category: 10-pin type.
Using the pin types of products for the introduction of i815, i815E, i815EP, KT133 chipset motherboard, etc., connected in the previous two types is much to be arbitrary, conclude, generally there are five access methods:. .
。.
. .
Generally speaking, pin 1 is the first set of USB power cathode, distinguish between pins 1 method is identified on the system board, and some directly marked "1", the black triangle or white thick lines. There is a certain brand of motherboard if two front USB connection for USB devices at the same time, there will be one of normal use, which belongs to the motherboard's Bug, two front USB separate use or normal.
■ case front audio wiring definition. .
Typically, the red line: MIC access, white line or green line: left and right channels, black: GND, in addition, there is an orange or red line provides power for the MIC. Chassis manufacturers in order to make audio wiring that are common to all kinds of audio interface board, signal lines dispersed design and to identify, but this is very rare, most of the audio line is a module for easy wiring.
Motherboard front audio pin definition. .
First class: 10-pin type (one of the pins space), 10-pin type definition contains the following three ways.
(Of which Figure 12 Definitions of rare audio, only the public FR33E board used by the way). .
The second category: 16-pin type (two-room).
The interface between each board may be different, so I hope you read before installing the motherboard manual. .
