Yes, but Tim Ring told me you can't MU RP and NCE because of the different speed step protocols.

Separately, I couldn't connect to Ring's server Saturday, I read that connectivity was knocked out by a storm? I will try again, but didn't know what the situation was.

you should be able to use advanced consisting, but you will have to set the loco CV's manually.

does it support long and short DCC addresses?

Finding some quirks about controlling RP engines with my NCE Pro Cab. First, I was unable to connect at all with an LM2-equipped loco. Second, I found that you have to be in 128 speed step mode to connect with LM3 locos. Third, I had to first control speed with the wheel to get movement, only then would the speed buttons work. No MUing, but I knew that.

I've done the P2K S3.

Initial ponderings/questions, etc. are posted here:
https://rpug.pdc.ca/index.php/topic,372.msg2787.html#msg2787

After that unit was done, I standardizes on Scale Sound Systems speakers and he came out with an new P2K S3 speaker in 2023, so I upgraded my P2K S3, which of course necessitated a bunch of adjustments.

Photos, etc. of that adventure were posted here:

RailPro Specific Help & Discussion / Proto 2000 S1 Module Install

As my layout progresses from the benchwork to actual track phase, the first area down and operational will be a yard.  I need to jump in and get a yard engine up to operational speed, the P2000 S1.  I aim to use the LM-3S-21 coupled to a Nix Trainz Decoder Buddy Mini, Power Bridge lll Stay Alive and a sugar cube speaker as well as LED front / rear lights.  1964 so no ditch lights thank goodness.  I would appreciate any advice or tips from anyone who has shoehorned all the needed elements for control and sound into the same tight confines of this particular model.  Thanks.

Here is a 9 to 21 adapter, not sure why it's called "European", for $12 .... maybe worth a shot ?

Just google 9 pin to 21 pin dcc adapter ....

I recently bought a DCC ready loco with a 21-pin plug but want to use an LM-3S module.  Is there such a thing as a 21-pin to 9-pin adapter?

Hey all,

I use the Decoder Buddy with RailPro LM-3S-21. Yes, you can use a Keep-Alive with the pins on the Decoder Buddy. RailPro's own works but I have also been making my own keep-alives for much cheaper and they last longer.
