I have a cable
with a DIN connector on one end and four RCA plugs
on the other. I've used a multimeter to determine which RCA
connector is connected to which pin on the DIN and have used the
RCA connector that connects to DIN pin 3 for audio output and the
one that connects to DIN pin 4 for composite video output. Is that
correct?
I can't recall, but I believe the audio RCA plug is either white or
red, if memory serves, if you're using a Commodore cable.
I'm not sure if this is a Commodore cable but the plug that connects
to DIN pin 3 (audio) is black and the one that connects to DIN pin 4
(composite video) is white. The other two are red connecting to DIN
pin 1 (luminance) and yellow connecting to DIN pin 5 (audio in). All
of the grounds connect to DIN pin 2.
