|ERROR FIXED||The pinout as far as USB connections go, is fine. |
Thanks a million for your submittal!!
The problem is with the illustration of the connector. It is labeled 1 over 2 and 19 over 20. looking at the connector from the top side of the motherboard, it should be labeled 2 over 1 and 20 over 19.
I have also deciphered (by trial-and-error) the jumpers needed to bypass the MIC connector and send the audio signal to the soundcard amplifier. I will try to illustrate it soon, and will send it to you for submittal. Thanks again!
|CORRECT||Thank You! |
In essence, the pinout is correct.
The connector diagram, on the other hand, is labeled incorrectly.
It should be:
When viewed from the top (connector) side of the motherboard.
|CORRECT||Pin 2 = still unknown +4.92V |
Pin 6 = still unknown +4.92V
Pin 13 = Audio Right IN (connects to Pin 10 when headphone is unplugged)
Pin 14 = still unknown 0V
Pin 15 = Audio Left IN (connects to Pin 12 when headphone is unplugged)
Pin 19 = MIC IN
Pin 20 = still unknown +4.76V
Motherboard is MiTAC 681xBU (Bluford), partial pinout from 6813BU manual.
Note: Unknown pins have to do with detection of front panel connection. If you find any other info about them, please contact me. -PiNkY

|2013-01-06 22:18:59||rev. 6||ERROR FIXED||Hello, It appears that you have the descriptions for pins 6 and 8 reversed. Instead of this: ? 6 -?- Unknown Vcc 8 -?- +5V for USB ~Both~ It should be like this: Vcc 6 -?- +5V for USB ~Both~ ? 8 -?- Unknown thank you.||APPROVED|
