So I had to get towed off the lake the other day. Keypad in the boat quit working. The boat actually wouldn't shut off when I hit the stop button, so I killed it with the switch under the dash (which was probably a bad idea) and then the boat wouldn't start again. Disconnected the battery, reconnected, nothing. Tore the dash apart, measured the 12 and ground going to the keypad, and power was there. Plugged it back in, and VIOLA, we have ignition.
That Deutsch connector on the keypad is a pretty high grade connector, so it leads me to believe that's probably not the issue, and something is probably hiding in the weeds getting ready to bite me in the ***. I've read the keypad bypass thread, and that seems simple enough for a "limp home" solution, understanding that the bilge/nav/anc lights won't work.
I understand that replacement keypads are available, but is CC actually still making these, or is this NOS? If so, it seems like a matter of time before that stock runs out.
That said, has anyone ever tried to figure out what the signal is riding on the green/orange wires? I'm a veteran electrical engineer and deal with microprocessors/comms/etc every day. Seems to me like this is probably a serial protocol, diffferential, and multidrop (since the wiring diagrams don't identify left/right keypad, and the plugs are the same). Probably 422 or 485. Has anyone every sniffed it with a scope?
Knowing what this is might be a really useful piece of info, just in case someone wanted to manufacture replacement keypads, or diagnose keypads, or say do something wacky like use a serial to bluetooth converter and control your boat from a smartphone.
I will probably put a scope on mine when I haul it out for the winter, but I was just wondering if anyone has ever done anything like this before....
