This cable extends 2 USB ports (type A) to the front panel of PC system. The cable is compatible with both USB 1.1 (standard) and USB 2.0 (high-speed).
DUAL USB TYPE A INTERNAL
Red: + 5V / Voltage + / VCC
The S-GND wire is fatter and can be easily recognized.
The shiedings of the 2 cables are shorted (connected) internally and converged into one S-GND wire. 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; and each header 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 header, in such that; the wires are correctly connected to the appropriate pins (i.e. wire assignments and pin assignments are matched).
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
Diagram 1: On some motherboards, the 4 active pins are not arranged in one same row.
Diagram 2: Before shifting the wires, use a marker pen to mark the green and white wires located in the same row. It means that these 2 wires work as a pair. The other green and white wires (unmarked) work as another pair.
Diagram 3: Connect the wires to the header in such that the marked green wire is connected to USB1+ pin and the marked white wire to USB1- pin. The remaining wires are connected to the other pins according to their assignments. The connection of S-GND wire is optional.
