They are very nice when you have a 8 pin plug, as I mentioned, I have used the "short" harness which is 1" long.

Welcome!

Unfortunately, with the way ESU/Scaletrains designed the motherboard on the rivet counter units, the LM-21-3S (and more specifically and Non-ESU decoders) doesn't play nicely with ScaleTrains 21-pin locomotives. I've spent the last year (on and off) understanding the motherboard in a ScaleTrains GP30 and I know why the LM doesn't work. I have not been able to figure out a way to make it work without replacing the ScaleTrains motherboard. DecoderBuddy is the best route I know of at this point to replace the  motherboard.

Also, read this thread where Kevin has some more information on the 21-pin with a ST loco: https://rpug.pdc.ca/index.php/topic,1666.msg11645.html#msg11645

I can't speak to the load balancing as I use RailPro on my small (in progress) switching layout, although from what I have read it works well and can be used with DPU's.

The lighting effects with the LEDs are really great and mimic the prototype extremely well. Also, if a lighting option doesn't exist, Ring is available to help.

Hey guys and gals!!

I'm doing some in depth researching on switching from Loksound to possibly Railpro.

Has anyone did a Scaletrains ES44 21 pin install and if it has played nicely with the board.
Also hows the load balancing system between the loco's ?
How is it with the lighting effects with the Led's ?

I used to have  a older railpro system 10 years ago and with Loksound decoders hard to get currently I'm looking at something different.   

Many thanks!!!!

CJ

Howdy there LVRR 1856 - I've always been attracted to the Lehigh Valley paint scheme(s)!
That's one nice & simple install there. Thanks for sharing!
That's a good trick with that Digitrax wiring harness. I was unaware that was an option. I can see how it can make life simple. I will certainly keep that in my back-pocket for a future install.

Hi RP Folks,
Just wanted to share my Stewart C628 RP install.

The Base DC Locomotive comes with 8 pin plug, and the circuit/light board has directional lights/built in resistors - Yellow/green and Red LEDs (directional), but oddly - no white head lights?
I may try to wire them in in future.

Anyway - Simple install.
8 pin to 9 pin adaptor harness - 3" digitrax part DHWHP
LM3s Module
11 mm x 13 mm cube speaker - crude engineering with baffle.

I usually use the Digitrax short 1" 8 to 9 pin harnesses, byt needed a bit more length to get module to front of the board.
Also had to extend the brown speaker wires a tad to reach the speaker in rear.
Taped the module up to bottom of board, and DF taped speaker with 3M foam tape - simple and easy.

Works Great ! Enjoy -- hope this helps.

If you haven't already detected it and accidentality forgotten that you did (it happens) the LM could be dead or may have a password on it. If you don't know what that password could be then you can try resetting the password. The instructions for resetting the password are in the HC-3 instructions, page 26 to be exact.
