Lost lighting direction on old Soundtraxx LC decoder....need CV value.
Posted by Anonymous on Thursday, March 21, 2013 8:27 PM

I needed to reset the CVs on a F series loco equipped with a Soundtraxx LC decoder.  Before I had the lighting direction matched to loco direction even though I had reversed the normal loco direction in the settings.

Now I cannot see how to get that back....the loco needs to have direction reversed and I need, therefore to reverse the lighting function....yet cannot see in the manual how to do this easily.....only a CV that matched lighting to loco direction.

So that I don't have to pull the shell off and rewire the motor leads, can anyone tell me a CV for this decoder to reverse the lighting control.....it should be possible because that is the intent of offering a CV to change direction....that the light could be changed also.

Just too old to remember what I had done before.

Thanks.

I believe that you need to set CVs 33 and 34.  See page 24 of the manual: http://www.soundtraxx.com/manuals/lc_manual.pdf

Thanks.  That's it exactly.  I was not used to looking in function mapping to set the lighting for direction of movement, but now it is clear.
