If I had started wtih a Digitrax DCS51 Zephyr as my first DCC device, I would have saved a lot of money.  This standalone device does it all and is completely expandable.  It is a remarkable device, all you need to get started and go way deep into DCC by only adding one item, a Locobuffer.


I found this quick reference on the Digitrax website and made a few adjustments so it could be printed and laminated back to back on half sized paper, just perfect to keep with the Zephyr.
