Great information! Very clear and helpful.
- You wrote "... I designed a simple 2-channel MOSFET power switch board". Did you ever post this design? I'm interested in PWM of a smoke heater unit as you describe in your post.
- Your use of the LokSound AUX outputs to control the smoke heater and fan was critical to me for selecting the LokSound L as the DCC decoder for a dead-rail conversion of a Sunset 3rd Rail UP "Late" Big Boy originally with TMCC. I needed a DCC controller that will operate the fan-driven smoke unit, so your post was decisive for me. Since you mention the LokSound XL in your article, I read the "Reference Manual for LokProgrammer" downloaded from here, and under section "11.2. Special Settings for LokSound XL" it states "…The function „Smoke Generator“ cannot be connected to the AUX outputs.” I was warned off using the XL version because of this, and the L version seems well-suited O, but others might want to use the XL version. Do you have any experience/info that the XL's AUX output can be used for fan-driven smoke units as you describe in your post? It might be I am misinterpreting the manual's statement, and you can set me straight.
Again, thanks for a fabulous post!
