To all who have experienced system wide disruption in DCC decoder equipped switch machine operations this was my solution to the problem.  I had 23 DCC decoder equipped EZ track switches stop working all at once.  I could not figure out the problem until Bachmann sent me a new Dynamis system to experiment with.  After hooking up the system all my switch machines responded as when they were new.  Then, after I entered my fifth locomotive to the new system's register all my switch machines stopped working again.  This was the AH! moment for the solution.  I removed the fifth locomotive from the register and all my switches worked again.  The trouble was not with the Bachman system but in a decoder of an engine I had a sound system installed by a professional.  I then reinstalled my old Dynamis system to my railroad and deleted the fifth engine from the rooster on the command station and (BINGO!) all my DCC switches began to operate normally again.  My suggestion to you if you have this same problem is to deleted all your decoder equipment from your Dynamis rooster and then reset your handset to (factory default).  Then reenter all of your extraneous DCC decoders one at a time until you find the one that is corrupting your switch decoders.  Let's all thank Bachmann's service department for helping us work through this problem to a solution.  Sincerely John the sailor.

After programing a new locomotive on the service track with my Dynamis Pro Box all 15 of my DCC switch decoders stopped working and will not function.  I have been reduced to switching them all by hand.  Nothing I have tried will get them to work.  I suspect the problem to be in the digital command control box but I am not sure.  When I press the individual programing button on the switches they toggle twice but do not respond to the switch buttons on the function mode of the Dynamis hand set.  Can anyone lead me onto the right track to get my switches functioning again?  I have become quite frustrated over this problem.  Thanks to anyone who might offer suggestions.
John

  ^{I have 5 DCC turnouts that are operating in reverse of the normal default position.  I have the Dynamis Controller command system but the instructions to correct this reversal in the switch instruction sheet only gives the correcting procedure for the basic EZ command controller.  How do I change these turnouts to the normal default position using my Dynamis controller?}
