    So do some fire panels, come to think of it. They use RS232 for programming, and either RS232 or RS485 for communication between modules.

      Yep. Coincidentally, part of that job involved a fire panel.

      It falls under the KISS principal - and if it ain’t broke, why fix it?

        Oh, definitely. There’s a lot of products in the fire industry that haven’t fundamentally changed since the 80s or 90s, maybe a few tweaks.
