For those of you who need remote On/Off control for your sony camcorder, I guess there’s a way you can hack the Mic input as Sony’s Mic input also includes control lines such as the power button. This might be helpful for those struggling to get the remote on/off to work.
We did a bit of probing with our multimeter, and discovered that the MIC jack on our sony camcorder supplies a small amount of power for the microphone, and most importantly – it turns this power on and off at the same time that the camcorder is turned on and off with the remote control! on our camcorder, we found that the MIC jack provides a 2.0V power source when the camcorder is recording.
