The CS2 can run on 14 steps, however there is an issue running the LGB 55020 and early LGB55021 chips because of the way in which they process instructions. They were designed to operate serially, in other words if you wanted to send an instruction to F5 it sent 5 F1s, I have over simplified this however I hope that you understand the principle. The CS2 cannot receive and transmit serial instructions. Why not try your Rugens with your local LGB/Maerklin dealer? I run Massoth chipped locos with 14 steps (mainly Stainz) with no problems.I'm currently running MTS3 indoors and have been thinking about upgrading. As issues like moisture and robustness are less of an issue for me I had been considering the CS2 as a possible upgrade option. However the more I read here, the more frustrated I become.There seems to be a lack of joined up thinking at Marklin in regards to compatibility (backwards or forwards) with the CS2 as the 28005 green Rugen loco (current catalogue) only operates on 14 speed steps. If the CS2 only allows 28 steps there seems to be a good chance of a magic smoke event. It seems to be pointless forking out upwards of A$1500 for a unit that is going to fry the board on one of my favourite locos!
I'm also looking at purchasing a 'Franzburg' (plus the 55028 decoder) and the club edition 'Spreewald' with the MFX sound chip on board, am I going to have issues running these on my MTS3 setup? Would things be improved if I use a Massoth navigator instead of the LGB 55016?

Thanks for clarifying that Martin. The Rugens does function in parallel on my MTS3 setup, so if the CS2 will run 14 steps it is still an option.
One of the problems of living in Australia is that my 'local' dealer is about 300km away. Mind you when I lived in Adelaide they were 1500km away - what Australian historian Geoffrey Blainey described as "The tyranny of distance".Another problem is that most of the time Aussie dealers carry very limited stock, with premium items (read expensive) often only available to order. The consequence is that one is frequently buying from a catalogue so the feedback and opinions of members of this forum is extremely important and highly valued by we antipods.

Hi Cliff,Well I'm confused even more now! If CS2 can run on 14 speed steps then why can it not drive engines with older decoders? Now it is true that if the CS2 does not support MTS specific serial functions then it will not be possible to operate functions in the decoder (except maybe the first one). However controlling functions and actually getting the decoder to move the engine are completely separated decoder features and therefore moving the engine on 14 speed steps should still work.
Any standard DCC system that supports 14 speed steps can get a 55020 to move even if it does not support serial functions (an example would be my Lenz system). In conclusion it is a mystery why older decoders cannot be controlled via the CS2.
Hi Cliff,
My comments refer only to the LGB 55020 and early 55021 and are based on a conversation I had with Marklin in Germany. I am not aware of the technical issues for this nor have I tested the CS2 with chips other than mfx, LGB55021 later version (2+) and Massoth equivalent. Perhaps the way forward is to actually test the CS2 with other chips and see what happens.

Good idea Martin.
It seems to me that there is a lot of misinformation about CS2 out there.
I actually think that the bidirectional nature of mfx and the way it allocated addresses is a good feature. For example users don't have to worry about address clashes when taking locos to another mfx line. But the system must be fully backward compatible with all DCC decoders to be of any use to most current users.
Hi Cliff,
I have just had a chat with a friend in Germany who is well versed on the CS2.
.......... The only issue is using mfx chips with Central Stations other than CS2 mainly due to programming which is different from Massoth.

Don't panic Captain Mainwaring,That last sentence worries me, Martin - is he saying that you can't program an MFX decoder with anything other than a CS2?
At our recent GSS area open day at Tolleshunt Knights, KGR sold a new MFX-chipped Tm2/2 RhB tractor to a visitor who wanted just the loco address reprogrammed to something other than the default 3; a display layout using Massoth control and a Navigator offered to try to do it, but despite multiple attempts, detailed reading of the manuals (both MFX and Massoth) and a small crowd of people trying to help, many of whom knew their way around Massoth systems, they were unable to change the address as far as I'm aware.
I've not yet purchased any M/LGB loco with an MFX chip installed - I got the new Franzburg but bought an XLS-M1 for it from Muns (GRO) - and the more I read, the less I want to get any.....
Jon.
Hi Cliff,
.....
The locos equipped with these chips will work but without any functions.

The chips have to be reprogrammed to exclude MTS.

Thanks Martin, that confirms what I thought would be the case.
I also don't believe a previous claim on here that CS2 cannot drive MTS II and below decoders.
Sorry I'm lost on what this may mean?
