Hello Märklinists...

Apparently my VT 08.5 has an ESU 4 decoder.
I am told if I set the register 75 to say 09 and then I can access F5-F8 by dialing up 09 on your 6021.

If so, how do I set the register 75 to 09 in the decoder with the 6021?
I have never set an CV settings with my 6021, although I have seen in the manual.
What actually is "register 75".
Any step by step help on this would be fantastic.

Also if this works, does anyone know if this would work for my M39100 VT 10.5 Senator?

Also anyone who has an 6036 80f controller and cable they want to unload or trade for I am interested in buying one.
I may be able to get a 6035 80 but since that unit does have the function buttons, I would prefer to get the 80f
(Guessing they gave it an 'f' in 80f to mean it does have function buttons.)

Thank you!
- Mark

Hi!
Ex works it had an ESU mfx decoder. The ESU 4 decoders came many years later.

With mfx decoders it is 03 for acceleration delay and 04 for braking delay with a value range of 1 to 255 (6021 is limited to 01 through 79).

I believe it will work for all mfx decoders, as until mfx decoders were introduced Marklin decoders were limited to 4 functions plus F0 lights. So the dual address method was provided to allow those buying new items while using there existing digital system, and provided access to 8 functions for these users.

Also I believe that there are some recent decoders that can be set to 4 different addresses allowing access to all 16 functions from a 6021, but this doesn't seem to be widely disseminated information. I can't recall off hand if this can be done with Marklin decoders, but I think ESU loksound v4 decoders can (I think this is how I came across this ability).

Thanks again to Tom and David,
After reading the description in the locomotive/railcar brochure and looking at the odd diagrams of the 6021 with the arrows all around it, your simple description was by far the easiest way to do it. In fact, it was so simple I carefully read out the both of the descriptions to my daughters to compare them and my 12 and 10 years old girls programmed the second address and gleefully tested the new sounds. Great thing about this was for them to see they could change the settings themselves and now are gung ho about changing the other CVs. Got to make sure they don't get too enthusiastic and go for everything at once.

The one minor snag is that when you turn off the power to the 6021 and start it up the next day/later the sound of the new functions is played on the locomotive until you punch in the call number and stop it. Spoils a bit of the drama sequence when showing it off to guests.

The new generation of Marklin decoders have up to 4 addresses that can be set to allow access to 16 function - F0 thru F15. There are some recent posts in the forum by (Peter) Clapcott describing this feature - will see if I can find them.

This Christmas we got around to programming a second address for the VT 08.5 so we have four new functions, but then when I went to refer to the manual to find out what the default CVs are ...such as volume control values, I could find none.

So my first question here: What are the factory value settings for volume? I am hoping to avoid having to set them over and over until I find the right one.

Secondly, I noticed that there are two more functions that I don't have in the two addresses. And the option for compressed air would be interesting. So how do I set a third address for the locomotive for the other two addresses?

Cheers,
Mark

(Really enjoy seeing the posts again after a year's absence.)

Make sure your VT 08.5 has a Märklin decoder. The first version with ESU decoder is limited to 2 addresses.

Ok Gents,

Concerning my VT 08.5, M# 39080 I tried to set the third address using register aka CV17 by itself, then I tried to set three addresses using CV49 by itself, and then CV49 to three in value so that I could then set the the third address with CV17. I tried the combinations multiple times, lights of the loco flashed and everything seemed to be done correctly. However, none of these worked, so I am assuming that either the decoder does not respond to the third address being programmed or that I am doing something wrong. I am not sure of the date of manufacture, as I read somewhere that only certain decoders have/had that ability.

I have managed to program the max speed and breaking and acceleration delay without problems.
As well as the second address.

Another curiosity though: Is it possible to program the volume of sounds independently within one decoder?

I wanted the engine sounds slightly louder, but the horn is too loud and I am concerned it will damage the speaker at that volume.
I have the value currently set at 27 but I imagine this all varies from decoder to decoder.
Again I wish it were possible to know the default values of each locomotive, before playing with them using the 6021.

I am wondering if I could find someone locally with a CS unit that could change around some of the F settings. Would it be possible to change the position of some settings... say trade places between F8 and F9?
