I looked up "cashline" using Google. One search led me to casline.ca, which redirected me to DirectCash.net.

I got to thinking that someone from Texas saying "cashline" might sound like they are saying "cashlane" (sorry, that's this Californian's point of view).

At any rate, I'm guessing this machine was purchased through a secondary market supplier, who can't actually get the right cable.

Nice job on the diagram, by the way.
