Reply to "R2LC Serial Data Buffer"

Yep, I used pin 20 for the 5V power and pin 24 for the serial data. The output of the buffer feeds the RS Commander. With that installed, everything works fine, and the serial data has an additional volt + of amplitude, obviously the RS Commander imposes more of a load than I'd expect for a new product. I'm guessing it's feeding an opto-isolator as the rest of the circuit's DC ground is NOT common with the frame ground like TMCC.
