I've run into a problem entering my new ESU Loksound 5 decoder into my MS2.

I recently purchase a new ESU 58419 LokSound 5 Standard Multi-protocol (DCC/MM/SX/M4) Sound Decoder - NEM660 21MTC Integral Connector. Since I don't have a ESU programmer, I requested my dealer to install the sound file I selected from the ESU Sound File downloads. After installing the decoder and beginning to uploading to my MS2 (new, black) I selected to enter it manually so I could use DCC and have the ability to adjust the CV settings. Well, instead on the MS2, the "MFX" starting flashing and it uploaded using MM2. When it finished, I checked all the functions and all worked OK. However the running characteristics were rather jerky and not acceptable.
My hoped for solution was to uninstall the loco and re-install manually using DCC so I could then be able to adjust the CV settings. The problem is that even when I delete the loco and go to upload it manually back onto the MS2 I can't get any functions to operate. I even tried to reset the decoder to factory defaults using "3" as the address, but no luck. I also tried to upload and changing the address and the engine slightly jerks indicating that it's getting the signal from the MS2 but nothing changes.
FYI: the motor in the engine is the Swiss made Maxon. So when I able to get this problem worked out, any recommended CV settings for this motor would be appreciated. It will keep me from have to find them by trial and error.

Thanks!

Thanks Tom for your help.

Are the direction to disable the MFX in the MS2 manual?

My understanding is that my MS2 has the current updates. I'ts about 1.5 years since I purchased it new.

I'll give it a try this evening.

I was able to find and set the MS2 to DCC. I was also able to get it loaded and running that the starting and stopping are rather jerky. I need to start experimenting with the CV values to get it tuned in.

Thanks again for all you help Tom.

Thanks John, I'll give them a try!

John, these didn't work for me, I planning on trying the auto tune feature and see if I have any luck going that way.

P.S. When I get the performance I'm looking for I'll get them posted here.

Yea John,

It's item 37450 BR45 Insider Loco. I had the boiler off and it clearly has written on the motor "Maxon, Swiss Made".

I have a list with The ESU recommendations for all the Märklin motors and this is where I originally started. The performance at start up was a little jerky and I upped it 1 volt and this seemed to solve the problem. The other issue is when coming to a stop, it slows down and then right before it comes to a complete stop, I jumps quickly forward about 3 cm's before stopping completely. I haven't be able to really test the performance. Thsi is just on a 3 foot programming track.

Maybe this will help, here are my settings for the same loco with LS3.0 M4. It's a bit simpler since additional motor CV's were introduced in later loksounds.



voltage is CV53
parameter 'K' is CV54
parameter 'I' is CV55

John, I can't answer for ESU. I found this info on page 48 of the Loksound 4.0 manual and I printed it out to retain for reference. There is a chart on this page for all the commonly used motors and the one I referenced states under motor type, "Marklin/Trix locos with Maxon motor".

John, I know that I was using the Loksound 4 manual recommendations instead of the Loksound 5 recommendations. Sorry for any confusion I may have injected. I had printed out a copy of these settings and had them available when I did my initial setup. I had "assumed" that the reading would be the same for the Loksound 5 decoder too. (WRONG!)
The ESU Loksound 5 recommendations are on page 64 of their download from the ESU website. If I'm not mistaken the Loksound 5 recommendations look to be same reading that you had recommended from an earlier post in this thread that you had obtained from the ESU Programmer. Your right that in the end what matters is the CV settings that get the results you're hoping to attain. I must admit the motor "Auto Tune" feature in the ESU decoders worked well and I plan on using it again if needed.
