ZIMO – Special function mapping
The relevant allocations can be activated by programming the desired number to configuration variable #61. Function F1 along with some others can be mapped with specific function outputs, with the help of the
NMRA function mapping. For example, function output FO1 can be allocated to function F2 (CV #35 = 4) or special shunting lighting can be realized with CV #35 = 3 (both headlights on).
CV #61 = 97
Alternative function mapping for MX640 without “left-shift”:
CV #61 = 67 overrides the higher CV’s “left shift” (from CV #37) of the NMRA function mapping (see
previous page), which allows to map higher function keys with lower function outputs (e.g. It is not
possible with NMRA function mapping to map F4 to FO1 but it is possible this way; the downside is
that function outputs FO7 and FO8 can no longer be accessed!).

Directions Bit
Typical application: F3 (FO9): Sound ON/OFF, F5 (FO8): Bell, F2 (FO7): Whistle
when actuating an external (usually older) sound board.
Wenn CV #61 = 2
Wenn CV #61 = 1
CV #61 = 1 or 2
is very similar to the normal NMRA function mapping (which is CV #61 = 0), but…
…for many applications desired: actuation of
FO1
by the driving direction, that is by the
“directional
bit”
(when CV #61 =1) or by
F7
(when CV #61 = 2).
