Quoted from Aniraf:I found a bunch of stuff online, including kenlayton’s other posts, but I have yet to see something from Stern that explains exactly what this is.
If I understand you correctly, you are saying Stern pins this thing for 120VAC, but never actually hooks it up? So essentially the wires currently in there are dead?
Because Stern is not the ones setting this plug's standard. (Because they didn't 'invent' it. It's the same effin' 9-pin plug that was used in WPC games 25+ years go.)
It is a DBA standard.
Look in a Mars/MEI Installation Guide for ANY of the AE2x00 model DBAs. (In the AE2400 manual revision "GA", it's on PDF page 6 of 6.)
