The application of the “Swiss Mapping” is shown here with the
example
of an SBB Re422 engine.
The function outputs together with the connected
lights or groups of lights are shown here as they exist in
a typical SBB (Swiss) electric locomotive.
The task of the “Swiss Mapping”, with the help of the
function keys
F0 (General ON/OFF), and
F15, F16, F17, F18, F19 and F20,
is to correctly switch the lights in all possible operating
conditions (of course in both directions).
This results in the status table shown on the right,
for which the following configurations are required
in the “Swiss Mapping” (below):
#33 = 133
#34 = 42
#430 = 15
#431 = 157
#432 = 14
#433 = 1
#434 = 15
#435 = 1
#436 = 15
#437 = 157
#438 = 2
.
#439 = 0
#440 = 2
.
#441 = 0
#442 = 16
#443 = 157
#444 = 14
#445 = 1
#446 = 2
.
#447 = 4
#448 = 17
#449 = 157
#450 = 5
#451 = 6
#452 = 15
#453 = 2
#454 = 18
#455 = 157
#456 = 6
#457 = 0
#458 = 4
#459 = 0
#460 = 19
#461 = 157
#462 = 2
#463 = 0
#464 = 1
#465 = 0
#466 = 20
#467 = 157
#468 = 0
#469 = 0
#470 = 0
#471 = 0
Explanation:
The normal NMRA function mapping in CV #33 and CV #34 (front and rear headlight) deter-
mines the lighting in case when F0 is ON and function keys F15
– F20 are OFF:
CV #33 = 133 (= Lfor, FO1, FO6) and CV #34 = 42 (= Lrev, FO2, FO4).
The following CV groups (1. Group: CV #430
– 435, 2. Group: CV #436 – 441 etc.), each group
shown on one line, contain in the first CV the number of the
“F-key” F15, F16, F17, F18, F19,
F20, followed by
the CV’s for the “M-key” and function outputs to be switched.
N
ote that there are two groups for F15 (CV #430… and #436…) because F15 should switch 3
function outputs simultaneously, but only 2 can be entered per group (A1, A2 for each direc-
tion); one group is suf
ficient for all other “F-Keys”.
All “M-Keys” (the second CV in each group) are all set to “157”; this means that “F0”
and
the
condition of Bit 7 must be met, which means that the selected outputs are only activated if the F
and M keys are ON.
The third to sixth CV’s in each group contain the numbers of the function outputs to be actuated
(where the headlights are coded with “14” and “15”, for all other outputs just use the digit in
FO1, FO2…).
