Need help programming a HO ge 44 tonner

[nrscroller]

HI all
I am using a digitrax zepher and I need to program my bachmann HO ge 44 tonner with dcc on board. What mode do I program in, I have tried everythiing and nothing works. I even put a 12 volt bulb across program track and that doesn't light up or help.  I want to adjust cvs for smoother switching mode.
Thanks
Bill
