Hi All,
I have a TRIX 22232 BR218 with sound. It has a 21MTC decoder and a SUSI sound module.
F4 activates the sound but, at the same time, nulls the inertia.
It's clear to me that the decoder has F4 assigned to inertia and the SUSI sound module ha F4 assigned to activate the sound.
There are to possibilities, none of which I could implement.
1 - to assign inertia to F5 in the decoder
2 - to assign F5 to sound in the SUSI module.
Does anybody know how to do that?
There is no function mapping available in the Loco's Manual.
Thanks in advance for any help.

Hi!

22232 is an analogue model without sound.
I don't get a clear picture of the decoder on my crystal ball. Some pictures and the values of CVs 8 and 7 might help us to help you.
You cannot blame Trix that the sound functions are not described in the manual. Maybe an Uhlenbrock sound module.
Regards
Tom

Hi Tom, thanks for your reply.
Yes, 22232 is analogue from factory, but this one has been purchased second hand on eBay and it has a Trix (CV8=131, CV7=153) 21MTC Decoder with a sound module wired to it.
Both the Lokprogrammer and the Intellibox2 identify the Manufacturer as TRIX.
SUSI wires' colors and position in both the sound module and the decoder are compliant with SUSI standards.
I can`t identify the decoder product number. It's clear that it is neither an ESU nor an Uhlenbrock. Therefore, I can't remap the decoder's functions.
SUSI standard CVs are not accessible, so I can't remap the sound functions either.
This is why I have started another topic (I have your answer there...) for trying to replace the decoder by an ESU.
Altrernative is an Uhlenbrock with both 21MTC & SUSI.
Regards,
Jorge.

I'd try to change the decoder function mapping using the manual for the Trix 66849 decoder.

Do you get value 8 when reading CV 38? Try setting it to 0 and F4 should no longer toggle inertia.

Tom

Hi Tom, good catch!!!
I've set CV38=0 and no more inertia when F4=ON.
Unfortunately, I couldn't find the manual for a 66849 in the Internet.
Any link? pdf?
Any CV to change to assign inertia to F5?
On the other hand, I've found that the Loco's PCB has four soldering pads for connecting a SUSI device.
I've unsoldered the SUSI wires from the decoder and soldered them to the PCB directly.
Now I can exchange the decoder at my will.
I've also tried a Lokpilot V4.0 M4 and it worked fine.
Unfortunately, F1 & F2 no longer switch the lights off. A nice to have but not that important.
Anyway, I'd like to leave the Trix decoder where it is, with or without inertia.
Thank you much for your help.
Best regards,
JORGE

Hi Tom... CV39=8 assigns inertia to F5 !
Anyway, I'm interested in having tha manual...
Have a nice Sunday!

The address (to be copied to the address field):
Code:
http://medienpdb.maerklin.de/product_files/2/pdf/66849_betrieb.pdf
Vary the number to get other manuals (e.g. 66839).

Some MäTrix locos require amplified AUX3 and AUX4 for the light change to work. NEM-compatible decoders (e.g. ESU) don't have amplified AUX3/4.
This is a problem with the Trix TRAXX locos, but IIRC also with the BR 218.

So IMHO a case to follow the "never change a running system" rule - unless you want to install an ESU LokSound.

Tom

Hi Tom,
Again, thank you much for all your help.
I've downloaded the manual and now I have something to play with.
I'll take a close look at the PCB to see if there are some power amps for AUX3 & AUX4.
Also, I'll see in detail how the functions are mapped in the decoder.
In addition, I'll install the decoder on a ESU adapter with AUX3+AUX4 amplified outputs and see how the decoder works.
But... your last sentence is correct.
I've worked with computers for more than 40 years. There is a rule of thumb:
" MACHINE RUNNIN', NO TOUCHIN' "
Have a nice Sunday !!!
