    Thumbs up [RESOLVED] Where's the Headphone Connectors? Acer 8i945ae

    I have an Acer 8i945ae board which I'm trying to set up and I'm having trouble getting the facts on it. Motherboard diagram and full details.

    Acer don't help. They have an extensive site for self-help but it's all indexed by Computer name rather than board name.

    I did manage to figure out that this board came from the Veriton 5800 to 7800 series and downloaded the manual for that.

    But the motherboard pic doesn't show details of the front panel header. The pic actually has the front panel header labelled as the 'clear cmos' jumper. Also has the board battery labelled as 'parallel IDE connector'.

    So generally it just doesn't help enough to fix this problem.

    Can anyone help with this? Anyone got a Veriton and can check the leads for me, anything like that?

    Presuming that you actually meant the front panel audio connector and not headphone connector,

    If you have the their User's Guide,
    Refer to pages 44 and 45.

    Standard HD Audio header, in the usual location on number of mobos, not limited to Acer brand.

    I mean the headphone connector.

    I want all details of the front panel header on the board, in fact.

    I want clarification of a 4 pin USB cable situation I have.

    Here's how it is, to start again:

    I have the board, I've put it in an old non-acer case.

    It is working and now I want to hook up the front panel, and the headphones, and the usb lines to this new old case.

    The front panel header has fifteen pins - 7 x 2 and 1 single.

    They are labelled beneath the header:

    +msg- +pw- nc + act-
    +hd- -rst+ vcc +ood


    I've hooked up the on off switch to '+pw-' and that is working okay.

    But what do the others mean? I guess -rst+ is reset and vcc would be volts but what's the rest?

    And where are the pins for the headphones?

    And this old board has a couple of USB ports and lines running from them to the motherboard. But they are only four connector lines. All motherboard USB connectors appear to be 9 pin. What's that about?

    Oh, yes, pages 44 and 45. If we've got the same manual we must be talking at cross purposes. Mine only shows you where to plug external devices into the cabinet on those pages. My interest is in making connections on the board, between the cabinet and the board.

    'Standard HD audio header in usual location...... etc' is about as useful as me telling an equirer after the post office - 'oh, it's in the usual location..'

    There are no "headphone connector" on a mobo.

    The front panel audio header and front system panel header are two completely different things. I couldn't even begin to guess what those acronyms stand for (except the hard drive one). You'll need to contact Acer for a motherboard schematic.

    WAGs:

    "+msg-" possibly for a multi-color LED that blinks if there is anything other than normal operation ... part of the normal 'power on' LED

    "+pw-" power switch

    "nc" no connection

    "+act-" activity LED

    "+hd-" hard drive activity LED

    "-rst+" reset switch

    "vcc" power source

    "+ood-" <shrug>

    Thanks for the input guys, especially doc.

    Shinma had me dashing to have a look and sure enough the wire from the 'headphone' socket on the front panel actually came from a tiny circuit board there...

    I like that 'ood' shrug. good one.

    Taking a wild guess, OOD might be Optical (something) Drive, an activity led for the dvd/cd.

    You're actually ahead of the game. Years ago in a similar situation, OEM board, there was no labeling to even know which was the power switch pin.
