Club member has the Lionel Jr Mikado with railsounds 5.0 cab number 9639. It derailed last night and had that "bad smell". Looked like he smoked the R2LC 13 board. I swapped it with a version 8 which I have a supply of those. The engine seems to run fine with all the 5.0 features.

The $64,000 question is... what is the difference in the 2 versions? And can you swap it like I did in a small Jr. Mikado?

I am hoping someone from Lionel chimes in here. They are the true experts on the details but I know some folks here would know as well.

Thanks,

Ted

Ted, that engine was made with R2LC  C08.    Engine number 6-38616.  You are good to go with your choice.  When you program this locomotive, remember to use AUX-1  code74.  This engine did not have an IR tether but did use AUX code 74.  The code C13 R2LC   was mainly used to replace the C11 R2LC used in the JLC  GG-1 and the C12.  It had other uses but this was  a common use.

Ted,

I'm reasonably certain your first take was correct in both cases.

1) This loco shipped with an R2LCC13. While the advice I've been told is to replace everything up to C08 with a C08, and replace C11 and C12 with a C13, I can't think of a reason why a C08 wouldn't work in your instance. The later revs mainly covered features relating to speed control, the Acela and things like operating pantographs -- none of which apply to your loco.

2) Your reset code of 4 is correct. The 74 code inverts the serial line for the AD20 on locos with a wireless tether. Since your loco has a wired tether, 4 is the way to go.

Todd,

Using the engine programmed to a 4 on the r2lc, all seems to run fine. I just have to figure out why it slightly binds at times. This engine is a club members and at times, I am the repair doctor for the club. I was told to look at the brake shoes on the rear drivers that have the traction tires as they can be bent a little.

Maybe if I program the r2lc to a 74, it will say the "N.Y. Jets win the 2019 Super Bowl" ! Lol! 

Thanks, 

Ted

There might be some unpublished codes in the R2LC's, but I know that's a particular instance that was never planned -- as everyone knew the Jets were completely incapable of ever winning a Super Bowl.

In the manual number 74 was called for.  We are so lucky the Legacy RCMC board put those modular boards out to pasture.

It looks like the manual was wrong, unfortunately.

Can you help me understand why we are so lucky for the new Legacy boards? I completely get it from a feature/functional stand-point, but I don't understand what was so bad about the modular architecture from a serviceability perspective.
