My only comment is that MIC IN and LINE IN are only 3.3v when the option "Microphone power " in the camera under "Audio Settings" is checked and saved. Otherwise it is GND.
And I'm guessing that pin 14 is probably signal ground, though it may be tied to power ground, I dunno. I'm using pin 14 as GND for the mic. I didn't want to tear it apart and try to follow the traces.
Alrighty...so here is what I have determined. 3 - IO Port 4, 4 - IO Port 3, 5 - IO Port 2, 6 - IO Port 1, 7 - 3.3v power, 8 - GND, 9 & 10 are audio output, 11 - mic in, 12 - line in, 13 don't know, seems to float, may not be connected, 14 GND
So it looks like pins 11 and 12 are actually the audio input. I was playing around with setting the ports to GND and testing the pins and noticed that pins 11 and 12 no longer had any voltage on them. I set all the ports back to input - floating and they still had no voltage on them. That is...
Looking at the camera and there are 4 configurable ports. They can be configured for input or output and can be left as open circuit or GND. So it looks like I can eliminate 4 more pins by setting these to output and GND and then finding them. So that is 10 of the 14 pins and there is a audio in...
11 and 12 are at 3.25 V and 14 is at GND. I am waiting on the connector to be able to test the ones on the top row as I can't reach them with my probes. I'm looking for the Mic in and as long as the pins don't have voltage on them I can hook them to the microphone without worrying about damaging...
Thanks for the reply. Can you tell me which 2 pins on the connector the power pins are? That will eliminate two more pins from my searching. I have already identified 2 ground and 2 x 3.3v so with these two that will drop me down to 8 possible pins.
Did you ever get or figure out the pin out? I'm trying to connect a microphone to one of these ports. You probably already know but the mating connector is a Molex Mfr. #: 51353-1400 and the pins are Mfr. #: 56134-9100.
