  • I’d wager this will not support hardware flow control. I’ve bought about 10 different kinds off ebay so far, several look the same as this, and none of them stop sending when my plotter buffer is full (unlike my physical serial port in my old PC, which does work fine).

  • Software!? Your computer features heavily… what software(s) are you using on it?? For example, I’ve tried a couple of different web-based circuit design “solutions”, and found them to be easy-to-use and utterly-useless at providing any kind of “working” simulation of my circuits. On the other hand, I’ve failed to get any of the more-expensive ones to work, because they’re totally incomprehensible to use. Lots of people make cool stuff nowdays, so I’m guessing there’s something out there that actually works, and isn’t impossible to understand and use?

    But what it is???

  • Grumble. You get the drill…

    12 Tx ipod sending line, Serial TxD 
    16 GND USB GND (-)
    18 3.3V 3.3V Power (+)
    30 GND 
    .
    1 GND 
    11 AUDIO_SW 
    13 Rx ipod receiving line, Serial RxD
    15 GND Ground (-)
    21 Accessory Indicator 
    29 GND 
    
  • Oops - forgot to turn my ascii-diagrma into [CODE] - here it is again:

                **    ** **                **
     2 4 6 8 10 12 14 16 18 20 22 24 26 28 30
    .
     1 3 5 7 9 11 13 15 17 19 21 23 25 27 29
     *         ** ** **       **          **
    
  • iPod pin 21 is the accessory indicator, so we can tell from observation of the photos the orientation of the plug (pin 21 is the 5th pin from the edge. There’s only 1 solderd pin in that place).

    Therefore - this must be what is connected:

            **    ** **                **
    

    2 4 6 8 10 12 14 16 18 20 22 24 26 28 30

    1 3 5 7 9 11 13 15 17 19 21 23 25 27 29


    12 Tx ipod sending line, Serial TxD 16 GND USB GND (-) 18 3.3V 3.3V Power (+) 30 GND

    1 GND 11 AUDIO_SW 13 Rx ipod receiving line, Serial RxD 15 GND Ground (-) 21 Accessory Indicator 29 GND

    I really wish someone could tell us what resistor was used on pin 21. The value of this baby is used within iOS to enable serial communications, and I’m itching to know what is used.

  • Nice socket… so where are the plugs?

No public wish lists :(
