: is an often used value for CV #431, because
F0 (= 29) is usually selected as the “M-key” with
Bit 7 = 1. F0 then acts as a general ON/OFF key.
= 255 (Special
high-beam
setting!): the Fu-Outputs
defined in the following four CVs are switched to full
intensity, provided that they are controlled via the
"normal function mapping", and dimmed with CV # 60;
this function is used, for example, to switch the
headlights of a Swiss locomotive to high-beam,
without switching the white taillight to high-beam.
Depending on CV #399 setting (see also below): High
beam is only switched on if the speed is higher than
the value given in this CV (in 255 speed step mode).

7…3 are
used)
0
Each group CV (i.e. #432, 433, 434, 435) can be
linked with one of these five dimming CV’s. The value
to enter is the dimming value (0
– 31) times the func-
tion output number (I.e. dimming value = 16 for func-
tion output 6: 16 x 6 = 96 is the value to enter).
This will dim the relevant function outputs accordingly.
Usable only with function outputs FO0 to FO8.

In conjunction with the “Swiss Mapping” special “high-
beam” setting, see CV #431 = 255; applies to each of
the 13 CV groups (CV #437, 443..):
Switches to high-beam only when the speed exceeds
the value in this CV; based on the decoder internal
255 speed steps.
EXAMPLE:
= 0: High-beam at any speed (incl. stand-still), con-
trolled only by the F-key (i.e. as per CV #430).
=1: High-beam only while driving (not at stand-still),
provided the defined F-key is ON.
= 128: Switches to high-beam when reaching medium
speed.
