MX46-633V CONNECTING FRONT USB


I believe you're referring to the AOpen MX46-533V

The Front Panel USB header is Blue in color, and located in-between the white No.3 PCI expansion slot, and bottom edge of the motherboard;

http://www.ebay.com/itm/AOpen-Model-MX46-533V-Socket-478-Desktop-System-Motherboard-/130774572519?pt=Motherboards&hash=item1e72c59de7

With the motherboard in the installed position;
5 pins across the Top row, 4 pins across the Bottom row.

Pins across the Top row are numbered EVEN
Pins across the Bottom row are numbered ODD

Starting on the Left side coming across to the Right, Top row;
Pins 2, 4, 6, 8, and 10

Starting on the Left side coming across to the Right,
Bottom row;
Pins 1, 3, 5, and 7

There are TWO USB connectors supported off of this USB front panel header.

For one of the USB front panel connectors;

A) Pin 1 is USB PWR 0
Goes to the VCC contact pin on the USB connector.

B) Pin 3 is USB_FP_P0-
Goes to the D- pin on the USB connector.
(Data - )

C) Pin 5 is USB_FP_P0+
Goes to the D+ pin on the USB connector
(Data +)

D) Pin 7 is Ground (GND)
Goes to the Ground (GND) pin on the USB connector

E) No pin 9

F) Pin 2 is USB PWR 0

For the other Front Panel USB connector;

A) Pin 2 is USB PWR 0
Goes to the VCC pin on the USB connector

B) Pin 4 is USB_FP_P1-
Goes to the D- pin on the USB connector

C) Pin 6 is USB FP P1+
Goes to the D+ pin on the USB connector

D) Pin 8 is GND

E) Pin 8 is USB_FP_OC0
Leave unconnected

This is more information on a standard USB connector pinout,

http://en.wikipedia.org/wiki/USB

( A USB connector, and a USB plug are not wired the same.
The plug is wired backwards from what a connector is.
Otherwise you would have power and signal going to the wrong pins, and burn the USB Front Panel header out on the motherboard )

There are two USB headers on the motherboard for the Front Panel,
JUSB1 and JUSB2. (Junction USB 1 and Junction USB 2)

Looking along the bottom of the motherboard, FROM the Right going towards the Left;

JFP1 header; (Front Panel main wires)
Header with 4 pins on the Top row, and 5 pins on the Bottom row.

JFP2 header; (Dual color Power On LED, and Speaker)
Header with 4 pins on the Top row, {Speaker}, and 3 pins on the Bottom row.

JUSB2 header.

JUSB1 header.

EACH USB header will support TWO USB ports in the Front Panel.
JUSB1 supports two,
JUSB2 supports two.

For each USB header there are 5 pins across the Top, 4 pins across the Bottom.
The pins are numbered EVEN across the Top, and ODD across the Bottom.

Starting from the LEFT side going across to the RIGHT side;
on the TOP row for JUSB2 and JUSB1;
Pins 2, 4, 6, 8 and 10.

Starting from the LEFT side going across to the RIGHT side;
on the BOTTOM row for JUSB1 and JUSB2;
Pins 1, 3, 5, and 7. There is NO pin 9.

A) Pin 2 is VCC
B) Pin 4 is USB1-
C) Pin 6 is USB1+
D) Pin 8 is Ground

E) Pin 10 is USBOC

Pin 10 is N/C -> Not Connected.
It is there, and Pin 9 is not there, to key which way a connector can go on. Only ONE way.

F) Pin 1 is VCC
G) Pin 3 is USB0-
H) Pin 5 is USB0+
I) Pin 7 is Ground

There is NO pin 9.

(The USB technology used is USB 2.0)

http://pinouts.ru/Slots/USB_pinout.shtml

Let's read together,
Under - USB pinout signals;

"USB is a serial bus. It uses 4 shielded wires: two for power (+5v & GND) and two for differential data signals (labeled as D+ and D- in pinout). NRZI (Non Return to Zero Invert) encoding scheme used to send data with a sync field to synchronise the host, and receiver clocks. In USB data cable Data+ and Data- signals are transmitted on a twisted pair. No termination needed. Half-duplex differential signaling helps to combat the effects of electromagnetic noise on longer lines. Contrary to popular belief, D+ and D- operate together; they are not separate simplex connections."

See the USB examples in the link above, where it labels the contact pins?
The MALE connectors are shown on the Left side.
The FEMALE connectors are shown on the Right side.

Your USB ports will be FEMALE, on the Front Panel.
They are also the A style. USB A style. The Top example to the Right.

Just noting the following in case for some reason, the wires coming from those contact pins in the female USB connector, are not color coded correctly;

Even after you have the wires sorted out, as to which contact pins they go to, DOUBLE-check again. Do NOT just go by the color code of the wires.
Why?

You do NOT want to accidentally connect the +5 Volts (VCC), to the Ground!

Explaining further;
You connect the VCC wire, (Red), of the USB port in the Front Panel, to the Ground pin on the USB header on the motherboard.

(Which means the Ground wire of the USB port, (Black), will probably also be connected to the VCC pin, on the USB header of the motherboard)

Zzzzzzap! There goes your front USB ports. Both USB front panel headers on the motherboard, will be DONE!

Make sure!

Going on;
1) VCC or Vcc, goes back relating to Transistor technology.
Just think of it as the Positive, or power wire.
It is.
It is 5 Volts DC.

2) GND is Ground. It's a DC circuit, and you have a Positive, and a Negative, or Ground.

3) USB1-
That is -> Data-

USB0 is for one USB port in the Front Panel.
USB1 is for another USB port in the Front Panel.

[ Each USB header on the motherboard can be connected, to TWO USB ports on the Front Panel.
Therefore for the two JUSB1 and JUSB2, you can connect Four USB ports in the Front Panel ]

Data- on one USB port in the Front Panel, goes to USB0-

Data- on the other USB port in the Front Panel, goes to USB1-

4) Data+
Same thing.
Data+ on one of the USB ports in the Front Panel, goes to USB0+
Data+ on the other USB port in the Front Panel, goes to USB1+

EACH side of JUSB1 and JUSB2, will support one USB port on the Front Panel.
Two sides per JUSB1 and JUSB2 = 4 USB ports on the Front Panel.

For additional questions, or clarification to anything I have stated above, please post in a Comment.

How to hook up the face plate of a emachine w3400 Wich includes 3 wires 1 power butten and 2 led lights


Look at the pinout of the Front Panel header, of the eMachine W3400's motherboard.

The plastic front of the computer is the Front Panel.
The area of pins on the motherboard, that the cables (Wires) from the Front Panel connect to,
is the Front Panel header.

The motherboard for an eMachines W3400 desktop computer is an MSI ms-7145
(Micro Star International)

Orient the motherboard in your view so that we are both looking at it the same way.
Processor to the Top, Ram Memory slots to the Right, white PCI slots (3) to the Bottom.

JFP1 is the Front Panel header.
(Junction Front Panel 1)

JFP1 is on the Bottom Right corner. There are two columns of pins arranged vertically.
(The JFP1 header runs parallel to the Right side of the motherboard)

The Left side column of the JFP1 header is numbered Odd.
Starting at the Top and going Down, the pins are numbered;
1, 3, 5, 7, and 9

The Right side column is numbered Even.
Starting at the Top and going Down, the pins are numbered:
2, 4, 6, and 8.
There is NO Pin 10

A) Pins 1 and 3 are for the HarDDrive Activity LED light. (HDD)
If the LED light is dim will operating switch the wires around

B) Pins 5 and 7 are for the Reset switch. (Reset button)
> IF Used

C) Pin 9 is Not used. (NC. No Connection)

D) Pins 2 and 4 are for the Power On LED light (If dim switch the wires around)

E) Pins 6 and 8 are for the Power On switch. (Power On button)

Trace the wires back to the Power On switch. Even if it means temporarily removing part of the Front Panel to see.

Same with the LED lights.
See which wires go to the Power On LED, and HDD Activity LED. (Harddrive Activity LED)

Follow the 3 wires, and tell me where they go to on the Front Panel.
USB port?
Memory Card Reader?
Firewire port? (a1394)

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
directron_1721_2292726
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

usbinst4
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.

Havimg prob with the 2 usb ports located in front


Hi manky, Normally front USB ports have a pair of 4 wire cable with connectors marked red wire is vcc; white wire is -D; green wire is +D; and black wire is gnd. The motherboard would normally have two pairs of dual pin connectors that would be sitting side by side or in-line with uneven pins - 4 and 5 pins; then another 4 and 5 pins. Please refer to the attached simple diagram for your connection. For some reason I couldn't get hold of a manual from the Gigabyte site of your particular model GA-81KHXT. Nonetheless hopes this works for you. Pls post again how things turn up. Good luck and kind regards.
