LGB DCC board time in/out

[pappde]

I have a LGB BR 995015 locomotive (LGB 20752) that has a DCC controller factory installed. I would like to install in this loco a Massoth pulsed smoke generator, the round boiler version, (Massoth 8415001). It needs timing input from the decoder. Which socket on the board is for timing signal in and which one is signal out?
All the other ports I have plugs already. I know the timing signal has three pins on the smoke unit.
Any help appreciated. I am a newbie here, I mostly work with live steam locomotives. This project is for the grandkids.
Thanks, Denes

I think there is a current thread about this. P phils2um found a Q&A on the maerklin user forum which shed some light on connecting a Massoth pulsed smoke generator to an mfx decoder.

Thnks, unfortunately it is about a different controller.

I should have taken pictures of my LD1 when I replaced the Märklin pulsed smoke unit earlier this year. I'm reluctant to open it up again just to take pictures! The decoder interface board is probably identical to what you're dealing with. I suggest you check the exploded parts diagrams for the most recent LGB Heidi. There may help there. They can be accessed on both the Märklin site, the Onlytrains.com, or Trainli.com site.

Edit added: LGB 20274 diagrams are no help. The parts diagrams on the new MLGB locos don't seem to show wire connections like the old LGB diagrams did.

I took a look at the interface board that comes with MLGB's new No.55029, 29 27 pin replacement sound decoder hoping it might line up with yours - it does not so no help for you there either. Maybe LGB333, Tom White will step in. He also has recent experience installing these smoke units.

As far as I am aware, there is no provision on the M1 27pin interface to provide a generated "chuff" signal. However there is a provision (input) to receive one from a "chuff" sensor.



The above image is a Massoth XLS-M1 decoder (which has the ability of simulating a "chuff" signal on output A3).

Thanks.
Unfortunately the schematics on the manuals do not image the sockets I was looking for.
How would I get the LGB part # for the board? Maybe knowing the part# would help looking for schematics.
Thanks, Denes
