Is it a Problem with my NCE Powercab or is it a Problem with the Loco Decoder?

Bryant asks readers this question:

“Hi and Thank you in advance. I am using NCE Powercab and attempting to change the volume in my Walthers Proto loco. I am successful at lowering the volume but at the same time changing the volume also changes how my cab works e.g.(the bell button turns on and off the headlights). Would that be a problem with the decoder or would it be a problem in the Powercab? Thank you for any help.”

    I don’t know the direct answer to this question but as a “hotfix” I shut off connection to the locomotive by unplugging the throttle and plugging it back in. The throttle buttons revert back to normal operation.

    If you know someone who has Digitrax system, try setting the volume with that to see if you have the same problem. Or, reset the decoder to factory reset and then change the volume to see if it does the same thing.

    I have an NCE System, and it is possible to program a loco on the mail line and a programming track. I prefer to use a program track myself. It’s not unusual to get the kind of problem you have with some decoders. For programming decoders, I use JMRI’s Decoder Pro, and a computer interface from NCE. It is the best method in my opinion, much easier to do. Decoder Pro is free online.

    Hi Bryant; i don´t know if this kind of Walthers Proto loco, uses two decoders, one for sound another for controling the motor. If that is the case I have a similar problem with a BLI (Blue line) and there was a conflict, because button that was used to sound the bell (F1) was the same used in the Lokpilot V3.0 to activate the function light button also connected in F1. In this case I disconnected the F1 from the Lokpilot decoder, and the problem disappears. I hope this helps you.
    Regards from Portugal.

    It sounds like it is an addressing problem. Some how you need to set decoders on different addresses to allow for the different functions to act independently of one another.

Use Tiny Railroad Micro Controllers

A micro controller is basically a small programmable computer device to help the model railroader “make things operate.” It is clever way to realistically replicate the movements, actions and functions you are likely to see on a full size railroad.

It’s YOUR Railroad!

Your rolling stock and locomotives might actually be the center of attention on your layout, but the scenic features that surround and envelop your layout is what's likely to make your train setup stand proud of the rest. Your selection of scenery and structures will add an element of customization that will make your railroad truly unique.

Scenery, structures, and fine detailing is a fundamental aspect of any good model railroad, particularly if it is intended to replicate a true-to-life railroading scene. How realistic or authentic you make your railroad is entirely up to you... and you alone.

Some enthusiasts like to replicate every tiny detail so as to accurately depict, in every aspect, a miniaturized version of a real life scene.

Others in this hobby adopt a more "free-style" approach and choose to mix and match accessories and features they personally prefer. Even though the purist will possibly be unimpressed with unrealistic or out of context elements, it is YOUR railroad layout so you can make it anything you personally want!
