Hi,

I'm replacing broken decoder of https://www.maerklin.de/...ts/details/article/37349 with mSD3 21-pin.

There seems to be no sound project available for #37349 so I tried #37301 project. However the lights seem to have a setup I'm not sure how it works. There is propably some logic in the PCB for the long distance lights as the light boards only have one white led per side and three red ones.

So does anyone have a working project for #37349 to share with me please?

I could always try to get rid of the PCB and solder the lights to work with just normal AUX outputs instead. Not sure how I'd implement the long distance lights thou... Headlights + Aux1 to the same LED?

Also some explanation on how the SUSI works, would be nice. The #37301 I'm using controls red marker lights and long distance lights with SUSI but headlights with normal headlight outputs (which don't work on the PCB either)

Thanks!

If I remember correctly, you can order a replacement decoder from Maerklin and they will preload it with the sound functions for the desired model.
I think that the closest model may be the 37359 Re 4/4II Green which came out in 2015.

I did some research on models that came out around the same time and could not find two with the same part number for decoder.

As I previously stated, you can order a replacement decoder from Maerklin and specify the model and they will program the sounds and setting for you.
I did not find the Maerklin sounds for the Ae 6/6, Re 4/4II or Re 6/6 to be very good. There are better options out there.
ESU has a decent sound package for the Re 4/4II, but IMHO the best sound that I have of all my Re 4/4IIs is Roco's OEM Zimo decoder.

I found this on Maerklin's website:

…well there seems to be no availability for either on Märklin servers.

Does anyone have this loco and would be willing to read out the decoder to a new project? I’m sure I can get the sound slots in place afterwards.

I would love to download and send the decoder project from my 37349 for you, but I don’t know how.

The 37349 factory-installed mfx+ decoder (2014) is pre-mSD3, and is not recognized by the 60971 decoder programmer + mDecoderTool3, which can only read out mSD3/mLD3 decoders.

Also, while I can program the 37349 decoder with the CS3, I don’t seem to be able to download and save the decoder project from a loc – neither in the CS3 itself nor when CS3 is connected to mDT (mDT only enables the “decoder tester” dashboard for the 37349 on the program track, no decoder read-out).

This has been discussed before many years ago, and nothing has changed? www.marklin-users.net/forum/posts/t42089

Am I correct that there is no way to download, save of backup decoder projects from a pre-mSD3 loc using a 60971/mDT3/CS3 setup?

The last Re 4/4II that I saved the settings for was the 37356. Since Maerklin changed from ESU to in-house decoders, I have been unable to save the data with the ESU Lokprogrammer
I wonder if there was a way to save the first generation ones using the CS1 or CS2. I think that the new ones can be saved using CS3 or the Maerklin programmer.

I do know that if you specify the model, Maerklin service will prepare a decoder for you on spec.

I'm afraid the light settings seem to be a combination of pcb hardware and dedicated (SUSI?) programming.
As far as I can see in the function mapping, the light functions such as long distance lights (= brighter headlight leds), Swiss white/red tail light, triple red warning signal, are not mapped to AUX outputs, dimming settings, or to logical functions (which are not available in pre-mSD3 decoders), but refer only to a "sound" file (e.g., sound13, sound16) that is the only output mapped to the light F-keys.

I'm not 100% sure, but I believe the susi settings are stored on the susi board, so as long as the susi functions are mapped to a function button, they should work the same way as with the original decoder.

In the lastest Cs3 software, the were some improvements related to susi cv configuration, in order to make it easier to read and change values etc.

Have you tested to see if the cs3 reads the susi board connected to the original 37349 decoder? (under the configuration tab and browse to the bottom)
I don't have the locomotive or any mfx+ "msd2" decoders with susi function decoders, so I can't test.
