    Connecting Front Panel To MotherBoard

    I ask the same questions in case forum and this would apply to the A8V if using the same case. I hope that I can get this system up and running for my sister this weekend.

    Here is what I got. Enermax CS-517AL case and Asus P5GDC-V Deluxe motherboard.

    The connectors of the front panel are labeled different (some) and too many connectors or not enought to hook up to the USB ports (2), 1394 port, and audio ports.

    Connecting MIC
    Motherboard pins
    MIC2, MICPWR, Line out R, line out L, and ground
    No problem with the line out R, L, and ground but the fornt panel connector for the MIC is labeled MIC IN. What pin does this one go to, MIC2 or MICPWR?

    Connecting 1394
    The ground connectors are the problem.
    There are 3 pins on the motherboard and 4 connector for the front panel labeled VG 2 each and GND 2 each. What one would be left not connected. All other connectors ok or should I connect the 2 GND together and the 2 VG together?

    Connecting the 2 USB ports
    Motherboard has USB +5v and I think that the front panel connector VCC 1 & 2 goes to it (need to confirm).
    Here is the pin layout on thre morherboard, the . will be the pin

    USB+5v . .USb+5v
    xxxxUSB-. .USB-
    xxxxUSB+. .USB+
    xxxxxGND. .GND
    xxxxxxxxx .NC (Xs are for spacing only)

    The problem is each of the USB ports has 2 grounds labeled GND and GND 1 & 2 Total of 4 grounds. As you can see there are only 2 pins on the motherboard for these connectors.


    On the grounds of the USB ports, should I connect the 2 ground of each together (USB Port 1 GND to GND 1 and the same for port 2)? I read the sticky but what ground would you leave not hooked up (case forum)?

    Should go to Mic2. Micpwr is voltage for a microphone that needs excitation voltage.
    You would then select mic2 or alternate mic in your mixer for this input.

    Connecting 1394
    The ground connectors are the problem.

    Looking at the manual for your chassis, there appears to be a misprint ...it shows VG as power on one and ground on the other. Normally VP would be power, and VG would be ground

    Do you have VP wires ?
    Otherwise I would connect the VG's to ground, along with one of the other gnd wires. The 2 GND wires are probably common and connect together on the front panel, you could test this with a multimeter.
    Have to be careful though because of the mix up on that drawing....do you have VP wires ?

    VCC1 and VCC2 are the +5v .
    I would connect up the GND1 and GND2. Again the grounds might all end up being common or connected on the front chassis.
