: Pin 10 typically carries +8V DC from the sub to power the pod.

Look at the sticker on the bottom of your control pod or the back of your subwoofer. If the PID number is under 636, you have the older version featuring a detachable control pod wire with a traditional serial plug. PIDs over 636 use a slightly modified internal grounding path. logitech z-5500 schematic diagram
