@Bob posted:John, how will you do that? I thought RailSounds 6 needed a Legacy serial signal in order to work.
Well, I thought so too. However, I have the Lionmaster T1 Duplex and it's tender runs perfectly interfaced to my TMCC test-set with the IR link and an R2LC with TMCC. The only difference is the serial data across the IR link is reverse polarity, once I flipped the polarity, it works like a champ.
I also have one of the Legacy back-EMF cruise boards if it ends up being an issue, so I can just use that and the Legacy R4LC for the locomotive.
