HOW TO CONNECT FRONT AUDIO PINS


You should find a 7-pins connection on motherboard near USB-hubs and you find a more detailed position on Gigabyte.com

Connection of audio leads


Here is the link to the Gigabyte site to your specific motherboard. The only place that will have those pin locations is the user manual. Not all motherboards support all chassis designs and at times modification of the connectors is required in order to get the connections. Check the User manual for the actual pin outs.

How do I connect the front usb wires to my fic c51g motherboard header?


How to Install Front USB by Connecting Front USB Ports to a Motherboard?In order to have front mounted USB you must have 3 things.
  1. A case with USB ports in the front of it.
  2. A motherboard that supports front USB (usually)
  3. Appropriate wiring between the USB port and the motherboard
A case can support front USB in two ways: via a pass thru connection, or via a port to header connection. The former, pass thru connection, is compatible with all motherboards that have USB ports. Pass thru front USB Pass thru front USB works by having the ports on the front of the case connect to either a standard USB cable, or a fairly small rounded cable. The cable goes from the front of the case to a special slot cover with either a hole (for the standard USB cable) or a special connector for the rounded cable. If the pass thru USB had a standard cable, then you would simply plug the standard cable into one of your back USB ports. If it had a rounded cable, then you have a secondary attachment with something that looks like an old style SCSI connector. The attachment plugs into both the slot cover, and the back USB ports. The draw back of pass thru front USB is that you lose the ports in the back.

Many 3rd party devices that add front USB to a system use the pass thru system. A good example is this now discontinued Front IO panel

Front USB via a Port to Header connection In order to hook up a Port to Header connection you have to make sure that the wires from your port will connect to your motherboard's header. To do this you need to know what header you have, and what type of connector you have on the wires. You'll find information on both below.

Almost all motherboards these days have a USB header. Due to size and cost restraints many motherboards only have 2 USB ports on their back panel, but often they can actually support more then 2 USB ports. They will typically support additional ports via the use of a USB header. A USB header is either a single or double row of header pins on the motherboard that can be used to add additional USB ports to a computer via the use of an appropriate set of header connectors, wires, and a USB port. Each pin on the header corresponds to a wire inside a USB cable. These pins must be clearly marked so that you can hook them up to the wiring correctly. There are 2 common layouts for a USB header.

Intel Standard USB header Layout: (used by over 90% of motherboards)

instusb1a.jpg

Gigabyte Style USB header Layout: (used most commonly on Gigabyte brand motherboards)

instusb2b

Now that we know the types of headers we have to take a moment to understand the USB wiring. Understanding the wires First off: All USB cables have 5 wires. 4 of these wires are actively used. Here's a reference from the official USB standard.

instusb3

On a front mounted USB port you'll have either the first 4 wires connected to properly colored wires (red for power, white/orange d-, green/yellow d+, black for ground) or all five wires attached to the port (same as the former, but one extra black wire). Now where it gets tricky is how to attach each of those wires to corresponding pins on the motherboard.

The wires are "tailed" (attached to a header connector) using any one of a number of different types of connectors. Below you'll find a list of the common ones.

Common USB case header connectors 4 joined pins + 1 extra ground.
usbheader

Compatibility: Compatible with both header arrangements because of the extra ground. May not work with some odd arrangements To hook up carefully match each pin. For the Intel hookup you'll have the extra ground wire not attached to anything. For the Gigabyte hookup you'll have the extra ground hooked to ground pin on the motherboard, and the standard ground jumper will be over the missing pin on the header.

All pins separated

instusb6

Compatibility: Compatible with every header. If all the pins are separated the only real issue is lining up the pins with the appropriate places on your header. It should be compatible with all headers. Just make sure you read the writing on each individual connector. Please check the troubleshooting info at the end of the article for important information on this configuration

Power and Ground separate, d-, d+ joined Lian-Li style

Compatibility: Compatible with all common headers. This sort of arrangement is common to almost all Lian-Li cases. Make sure that you get the wires connected to your header in the proper order. If you find that the port does not function the most common cause is accidental reverse of the d-,d+. Try switching it.

All pins joined Intel style easy connector

making the Connection Once you know what type of header you have, and what type of connector you have on the wiring, you need to connect the two of them. In order to do this, you must first figure out what pin goes with what part of the connector. To do this, you should first consult your motherboard manual. Below you'll find an excerpt from a fairly recent motherboard manual for the Asus A7M266 motherboard. It's typical of a motherboard manual for a board using the Intel standard USB header.

instusb5

The first thing you'll probably notice is that the wiring from your case and the names of the pins might not quite match up name wise. This is a common problem. Motherboard makers and case makers really haven't decided on what to call each pin. Here's a rough list of names.

Power may be called: P, VCC, USB Power, Power, and PUSB. On wiring it's always red. Ground may be called: G, GND, Ground, and GUSB. D- may be called: USB-, USBP-, D-, or just -. D+ may be called: USB+, USBP+, D+, or just +.

To complicate things a bit more you'll probably notice that there's a number before each one. Take a look at the picture above from the USB hookup diagram for the A7M266.

You'll see that Asus decided to number the middle pins. On the first row (starting with pin 1, and marked with a 1) you'll find that they list D- as USBP2-, and D+ as USBP2+. The number 2 tells you a few things. First off: It's the 3rd USB port on the motherboard (they started numbering at 0), second it tells you that that D- and D+ must be used for the same port. Case manufacturers are just as likely to number their ports differently.

Take a look once again at the 4-pin joined picture: usbheader

Notice that you're D-'s have either a 1 or a 2 on them. These also tell you that they are part of the same USB port. (Remember, 1 port has 4 required wires). The numbering on the connector and the numbering on the header doesn't have to match.

To connect everything grab the following connectors: a same number D pair, (D-, D+), 1 power, and one ground. If your power and ground are numbered make sure all 4 are the same number.

Tip: Most cases that use all separated pins will bundle these together for you to make it easier.

Now, take your Power, D-, D+, and Ground and line the connector up with the appropriate 4 header pins on your motherboard. The header pins will be in a row under the Intel style, and in the Gigabyte style it will either be a row of 1 pin, a gap, and then 3 pins, or 3 pins, a gap, and then 1 pin. Press the connector down over the header pin and make sure it's firmly attached. Once you have done this go back and grab another set of connector wires (Power, D-, D+, Ground), and hook up your second front USB port. If your case has more then 2 front USB ports, and your motherboard has more then one front USB headers, then repeat the above as necessary.

Example: If you were hooking up the front USB on a A7M266, on a case with the pictured 4-pin joined connector type then: VCC lines up with USB Power, USBP2- lines up with USB1-, USBP2+ lines up with USB1+, and GND lines up with GND. For port 2, VCC lines up with USB Power, USBP3- lines up with USB2-, USBP3+ lines up with USB2+, and GND lines up with GND.

I dont know how to connect the usb port in my board


Connect the USB header to the USB pins on the motherboard.Generally the connection on the motherboard has 2 rows of pins, 5 on top, four underneath.There are 2 types of headers, 1 rectangular with 5 hols on top row and 4 on bottom. Connect to MB ensuring the holes match up to the pins. You may also have a 4 + 4 connector with 2 grounds. Connect so that the pins match up to the labels on the pins on the motherboard.ie. power, d-, d+, ground.

There are other motherboard USB configurations, but the above is for 99% of them.

Pls, need to attach front panel connectors to VTE


Diagonally opposite(diagonally opposite corner) to where you connect your mouse and keyboard, there will be pins on the motherboard to connect the front panel connectors. You can identify it by names written near it like SPK or Speaker, on/off and so on. The connectors on the front panel will also have names written on them. Just match and connect them. Reset switch, Power and speaker will not be a problem connecting. But hard disk light connector will be a little tricky. you have to connect to the correct polarity. USB connectors will be near these pins and will be labled as USB5 or USB4 and so on, on the motherboard. You will be able to insert the USB connector in one direction, so connecting it is not a problem.

I have the same problem!!!


Diagonally opposite to where you connect your mouse and keyboard, there will be pins for connecting front panel connectors. You can identify them by the names like SPK or Speaker written near them. You just have to match the front panel connectors with that of the pins. USB pins will be near these pins and will be labled as USB5 or USB4 on the motherboard. USB front panel connector can be inserted in only one direction.
