I finally got a stubborn DSC panel to talk to a new keypad by swapping the data pair

Had a job last week in a 20 year old house where the old keypad died and the new one just showed a blank screen, even with the right address. I was about to pull new wire when I remembered an old forum post saying to reverse the green and yellow data wires on the keypad side. Tried it and the thing lit right up, saved me at least an hour of fishing cable. Anyone ever run into that on a DSC 1832 before?

That trick can work, but it's usually a band-aid fix. Swapping the data pair often means there's a break or short in one of the original wires. You might have just gotten lucky that the keypad still works on a single data line.

My old garage door opener did that exact same thing last winter.
