Thanks!

I guess I should have mentioned that B loops around to B, and A to A in RAM's drawing. And yes, I am referring to Bachman's reversing units, not reversing tracks. 

The double crossover is intended to allow switching to/from either of two parallel tracks.  Here's the best I can do for a diagram:

    |      |
   /|      |
/  |      |
|   |\   /|
    |  X  |
    |/   \|
    |      |
    |      |

What is the correct configuration of your reversing units with your DCC double crossover?

I have searched and searched Bachmann "documentation" and the web for a clear description of how one programs Bachmann DCC turnouts using the Bachmann Dynamis system. The Dynamis manual refers to the turnout manual, but it's not there, other than some reference to another part.  I've spent lots of money the multiple DCC turnouts and right now I'm limited to reaching across my layout to flip them manually.

So...please post a clear, complete explanation along with other information about the turnouts; e.g., how many turnouts can be controlled through the Dynamis.

I was able to successfully program the turnouts with the introductory E-Z DCC Controller, but the limit there seems to be 7 (theoretically 9, but 3 doesn't seem to be usable--flips all switches--nor to 0 and 9.

Please help!  THanks.
