OK, i program right on the mainline, if you do, make sure ALL other engines are off the tracks, or on dead tracks:winki: .
hit the program button, the address of your engine will come up, hit the enter button, now type in the address of your engine.
hit the enter button again, now it will say "start volts", just keep hitting the enter button till it says CV#:winki:
once CV# comes up, type in 29, then hit the enter button again, now it will say "CV#" again, this is actually the VALUE, type in "1", and hit the enter button again, now it will read CV# again, THIS IS ACTUALLY THE BIT:winki: , type in "0" and hit the enter button again, now your done:thumb: .
I just did this to my H15-44 and it DID change the direction:thumb: ....now i have to change mine back:toug::119: .
hope that helped, :deano: -Deano
EDIT: if you ever wished to change it back, go to CV29, set the VALUE to "0", and then set the bit to "0" , i just done this to my H15-44 to get it back where it was from changing it the way YOU wanted it:thumb: .
