Look at the wiring diagram, the Veranda doesn't use the standard smoke unit commands, it has a unique motherboard with a microprocessor on the MB controlling the smoke units. The R2LC smoke output is likely used in the lighting operation. That's why the oddball smoke on/off controls.
The only thing I can add is that the smoke on/off routine you have to go through derives from the fact that like other TMCC and some early Legacy engines, the smoke units don’t shut down with the Railsounds. I find with my pair that after entering the normal shutdown command (AUX1 +5), the diesel smoke unit still runs. Not good for the model if it is standing on a powered siding.
Also the resistors on mine came stock with the fiber sleeve around them although I think they don’t have standard 27 Ohm resistors (have not checked the parts listing to be sure).
