I enclose a picture to give you an idea of where I am at CS3.

I have found a clue explanation on Stummi, but I can not find instructions, so I understand it.

Hope this will clear up some misunderstanding.
Yes it does. Thanks. Unfortunately others here trying to capture your thread for off topic stuff, especially attacking members again, instead to help you answering your question.
For myself the name telemtry for this point is not really a good one and can be misunderstood. Also I was not aware about this point. But I have to confess, I was not yet very much working with this configuration tab. Especially after I destroyed my decoder of my Insider V 320 (39320) by updating its decoder. It made me more sensitive for this section.
Also this tab varies from decoder to decoder. After seeing your picture I checked my just running 103 003-0 (31014-01 is a mfx loco not listed in M database). It does not have this telemetry point in its configuration section. At once I rerailed my 103-101-2 (26680 is a mfx+ loco) from the Lufthansa Express and whoops this loco has this telemetry tab on its decoder.
Then I checked your mentioned Stummi thread too, but it is not really helpful. The major problem for me is a value without any unit details. As one of the Stummi member wrote, he asked Maerklin and they gave him unit details, but they do not align with the values by his opinion. So it looks like even Maerklin does not know all by themselves about its decoder either.
I looked through all the books about the CS 3 and found only the information as given in the Stummi thread. Lenght related values are in cm. Time related values are in seconds. But everywhere the remark for this blue highlightend tab, only be used by experienced users understanding what they are doing.

This is not a sufficient documentation.
Also often it was refered to the decoders manual. But I never have seen such a manual for a built in decoder. I only saw a manual for conversion decoder sets.
https://static.maerklin....49aec5e3521564554225.pdfBut these manuals are pretty detailed. Maerklin told me once in the new locos are built in a version of their new mSD/3 decoders. Thre are little differences. But in general they are equal. Perhaps you get a look in one of these manuals, therefore your loco (37923) is a pretty new one. It could be equipped with a mSD/3 "light" decoder. Light, because your loco does not have a decoder inside understanding the DCC format.
BTW while it just happened to me. Never delete a mfx decoder unit (loco or coach) from your CS 3 while this decoder is off your tracks. Only delete it, if it is standing on your layout tracks! Otherwise this mfx decoder is not reregistering again. Found a thread about it at Stummis too.
https://www.stummiforum.de/viewtopic.php?t=169653In the thread only locos are mentioned, but for me it happened with a front forward cab coach with a mfx decoder inside. Same result. Not yet reregistered at my CS 3, although the coach is fully functioning and registering at my MS 2 and the track box. So the coach cannot be faulty. It must have something to do with the CS 3. I have to do further investigations.
All this not a fully satisfying answer, but nevertheless it may help you for a small step further.
