Atlas NJT multi-level cab car DCC installation
Posted by CJx7 on Saturday, May 30, 2020 11:25 AM

For my Atlas NJT cab car, I decided to install a DCC decoder to be able to control the various light functions.

All references from Atlas to installing DCC are for installing a LokSound decoder. However, I really don’t need the sound (and expense) in the car.

So got an ESU LokPilot FX V4.0 21 pin decoder.

Prior to installation, all the lights in the car come on as normal for DC operation.

I installed the LokPilot FX decoder and can now control headlight/marker lights with F0. They change based on the direction set.

The ditch lights respond to F1 and F2 respectively. Steady on. Haven’t done any programming on the decoder to make them alternately flash. Still reading through the decoder manual to figure that out.

The real issue is that the interior lighting doesn’t turn on with any function. From the directions for the sound decoder, it seems interior lights should turn on with F8 (which also turns on sound).

Looking for any help to resolve this mystery and properly program the decoder so that all the interior lights work and the ditch lights can alternately flash as well as turn on and off.

Welcome to the forum.  Your initial posts are delayed in moderation.

I don't have a lokpilot and am surprised how different the manual is for that vs a loksound select.  I'm going to pass on this one and wait for Randy who has experience with lokpilots and is one of the forums electrical gurus.

 It all comes down to function mappings. The Loksound sound project that goes along with the loco would have all the mappings set so the lights would work as expected. You should be able to to this with a Lokpilot, as long as it is not the Lokpilot Basic. You can actually get the CVs needed, if the OEM sound file is available (most are not, you'd have to ask Atlas to send it to you), which you could then open in the Lokprogrammer software and see the settings you need to apply.

The lokprogrammer software is free, you don't need the programmer to see what changes it recommends.  However if you have one, life is good.

I figure it's in function mappings and LokSound decoders have a ton of options in that area that I'm only beginning to explore. I'll pursue getting the sound file and figuring out the CV settings from it.

Thank you for pointing me in the right direction.

Don't have the lokprogrammer, but that's a good tip to download the software to view the settings recommended. I will do that. Thanks.

Success at last. With the LokProgrammer software, I was able to figure out function mapping and CVs and get a list of values to enter into the decorder. Then manually entered everything and presto, the cab car lights all do what I want them to do.

Life is good.
