I am in Miami, FL English-only. I am amazed how helpful you are to each other, and all around the world. Truly exceptional. So, here goes: I have Marklin HO C track with 10 turnouts (xx611/612), in a 1.2 x2.4 meter layout. When I assembled some track with 4 turnouts (, the MS2 recognized the address per dip switch settings for 2 of the 4. Then, after powering off, checking the other two to be sure the addresses were correct, power up and not even 1 of the 4 is recognized. I know the following: 1) dip switches are what I think they are (#1 thru #4 for Keyboard 1); (2) brown wire =O, Red wire=B on all turnout decoders (74461); with yellow wire=B on opposite side of brown and red (3) Dip switch #10 is ON; (4) The “Accessory Protocol = DCC ; (5) Even if I turn dip switch #10 off, and change Acc. Protocol to MM from DCC, it still does not recognize the turnouts. I am lost and WAY over my head. I was too timid to post initially, and I emailed Wolfgang in response to a post he had with a link to a German to English on-line translator that was truly fantastic. He gave me the courage to post here. So, here I am! Thanks for the consideration. Alan

Can't figure out how it recognized them at one time and not now, even moving several to a test track, which is working as it allows my loco to run, on luck with the turnouts . Again, greatly appreciate your response. Enjoy Florida! Alan

I didn't think they are, and if they are not they will not be automatically seen by the ms2.

At first, they were set to DCC and the MS 2 saw some of them. I have tried both ways, switch 10 off and on, changing the Accessary Protocol between DCC and MM. Still, no luck. Thanks for offering assistance.

My initially though would be first to use only MM protocol, program the 4 turnouts using the dip switches only. If that works you know your wiring is correct. In DCC mode I believe you can program the turnout decoder using a programming track, all though only possible with a central station. A factory reset of the turnout decoder could maybe resolve the issue if not working in DCC mode, but I let other more experienced MS2 users comment. Brgds Lasse

Now I have 20 turnouts and decoders (they are not cheap) and while the light comes on on the turn out the attemp to change via remote station 2 is not successful. In fact my yard is now running with the two button system as proving much simpler and reliable. I have not thrown in the towl yet but was wondering if anybody had some sort of check list to try and identify a problem. Could there be external factors that might affect the system like dirt, voltage, number of trains etc. ? I live in Honduras and am one of about three with railway spirit but the only one with Marklin. Appreciate your help. Richard
