This cable extends 1 USB port (type A) to the front panel of computer system. Cable is compatible with both USB 1.1 (standard) and USB 2.0 (high-speed).
USB TYPE A INTERNAL
Red: + 5V / Voltage + / VCC
The S-GND wire is fatter and can be easily recognized. The connection of S-GND wire to the header pin is optional.
Diagram 1: On most motherboards, the USB header/pin-out consists of 9 pins arranged in 2 rows, which allows for 2 USB connections (i.e. USB1 and USB2). Normally, the pins for USB1 and USB2 are in seperate rows.
Diagram 2: Simply plug the connector onto the 5-pins row, and make sure that the pin assignments and wire assignments are matched correctly.
Diagram 3: Alternatively, you can plug the connector onto the 4-pins row, and leave the S-GND wire unconnected.
You might have to rearrange the wires to match with the pin assignments, or change the header connector if necessary, depending on the layout of the USB header.
On some motherboards, there is a NC pin in the USB header. You can connect the S-GND wire onto this pin. NC simply means "no connection" and NC pin is an "empty" pin.
2X5 PINS HEADER
2X4 PINS HEADER
On some motherboards, the 4 active pins are not located in the same row, as shown in the example below:
To connect to this type of USB header, you need to change the header connector to 2x5. Simply rearrange the wires within the 2x5 connector to match with the pin assignments. If the green wire is connected to the USB2+ pin, the white wire must be connected to the USB2- pin. The red wire can be connected to any +5V pin, and the black (GND) wire to any GND pin. If there is no S-GND pin provided, you can leave the S-GND wire unconnected.
The 2x5 header connector can be purchased at our webstore.
