This has been a mind-numbing experience. The manual is right next-door to being useless. Just when you think you're on the right track, it's almost as though they forgot the last step !All I want to do is configure PORT 9 (flashing front overhead light) to be controlled by F3 and disable the sound currently in F3.After reading many other forums, it doesn't sound like too many people outside of the designers understand how function mapping works on these things. Even using Decoder Pro (which I don't have) isn't very clear and usually results in a guessing game.Mark.

After some research, it appears almost as though the only people that know how to re-map the functions on a Titan without their programmer are the guys that designed it !
Sure glad I don't have any of these myself !

The chart of interest is on page 7 of this NMRA document:

The problem, as I read it, is not in the Titan but rather in the limitations of the NMRA specification for how these work. Your choice of F3 is controlled by CV 37. That particular CV can only control outputs 1-8.
I think you could accomplish what you want using F4 instead of F3. Set CV 38 to 256 (0x0100) and set CV 43 to zero. If F4 is already busy, you can re-map that to F3 by setting CV 37 to 32 (0x0020).
