NMRA Legacy Function Mapping
CVs 33-46 (Function Status CVs) are function mapping CVs stated in the NMRA Standards for
DCC Configuration Variables (S-9.2.2). CVs 35-46 are used to assign effects to function keys
F1-F12, and CVs 33 and 34 are used to assign effects to the F0 function key. If the same effect
is selected for both reverse and forward F0 functions, that effect will turn on when the F0
function key is turned on regardless of locomotive direction.
Note:
CVs 33-46 are set to values of 0 by default, are a secondary method of function mapping,
and are not used to determine Tsunami2’s default function assignments. CVs 1.257-1.512
(Extended Function Mapping CVs) provide default function assignments for 28 function keys
and offer comprehensive function mapping support for all of Tsunami2’s effects in an
uncomplicated and versatile format. However, mapping an effect to a function key (F0(f), F0(r),
or F1-F12) using CVs 33-46 will override the corresponding function assignment mapped within
CVs 1.257-1.384.
