External serial port connector for P5B-E motherboard?

    The P5B-E motherboard has a single serial port that's not brought out to
    the rear panel. The book shows a connector module that mounts in an
    expansion slot with the note "The serial port module is purchased

    Is there some place I can lay my hands on one of these? There's no
    indication of a part number in the book.

    An "AT-Everex" perhaps ?



    There are two wiring standards for adapters. AT-Everex and DTK.
    Pccables carries both of them.

    Asus motherboards should all use the same standards. So
    if one Asus uses AT-Everex, they all should. I don't
    recollect any instances of users finding their *modern*
    Asus motherboard was a DTK.

    For reference, this is the link to the DTK flavor.



    And this is the guy who did the original research and concluded
    the 07120 was the correct one.



    I tried to reach estore.asus.com today, but got no answer, so
    perhaps they're out of business. They sell accessories for
    Asus motherboards, but only in a "half serious" way. There
    probably wasn't enough volume in that business, for it to stay

    That certainly looks like what I'm after; at the price, I could order one
    of each just to be safe.

    It might be far simpler to provide the vendor
    with the specific model/version of the motherboard.
    Failing this, send the spec sheet for the pinouts
    of the serial port header on the motherboard. It
    can be found in the motherboard manual.

    I have the manual here, e2779_p5b-e.pdf.

    No pinout, and no "name" for the type either. Just a
    stick art diagram showing the connector is 2x5 with
    a keying pin missing, which matches both the AT-Everex
    and the DTK. On page 58 of 158 pages total.

    And if I do a site search against asus.com , I don't find
    "AT/Everex" on the site, on say support.asus.com .

    So you're left to figure it out on your own.

    A site like estore.asus.com would have carried them,
    for North American customers. But that site appears
    to be gone.

    A poster on vip.asus.com suggests the "V1" connector here,
    and if you compare it to the 07120 Everex photo, of how the
    ribbon crosses over before being soldered to the solder-tail
    9 pin D-sub, it's te same wiring.

    You'd think so, but that's not the case.

    Yes, it's pretty annoying that Asus doesn't include that. I lucked out
    and found a suitable adapter for my P5Q Deluxe in the box of some older
    Asus motherboard. Of course that was after I managed to buy the wrong
    kind of adaptor.

    I Have A8N-SLI Premium And It Has A Serial Port Connector COM1. If
    You Get The Manual For The Site Page 2-25 You Can See. Part Number On
    The Bag Is "14G000020093". Found This Site.


    Good Luck,
