3.18 The ZIMO "Input Mapping"

Front Rear
SW versions 34 and up, also for function outputs via SUSI!
The NMRA function mapping limitations (only one of 8 functions per one of the 12 function keys) can
be overcome with the ZIMO "input mapping". In addition, the function keys (= external functions) can
quickly be adapted to the wishes of the operator and that for both, function outputs and sound func-
tions, without the need of changing the internally mapped functions and especially without changes
to the sound projects:
CV
#400
key switches the internal
#401
-
#428

3.19 Dimming, Low beam and Direction Bits

Some things connected to function outputs may sometimes require less than full track voltage, as is
the case for example with 18V bulbs when having 24V on the track (quite common on large scale
model railroads). Other times you simply want to reduce the brightness of the headlights.
The best solution in such cases is to connect the positive side of such devices to the low voltage sup-
ply of the decoder (see chapter "Installation and wiring"). These outputs are fully stabilized so the
voltage does not fluctuate with changes in track voltage.
Alternatively or in addition to this, the PWM voltage reduction is also available with
CV's #400 ... #428

Description
= 0: Key F0 (that is, F0 received from the DCC-packet)
is sent to the internal (decoder) F0 (1:1).
= 1: Key F1 is sent to the internal F0.
.....
= 28: Key F28 is sent to the internal F0.
= 29: Key F0 is sent to the internal F0.
= 30: Key F1 to F0, only in forward direction.
.....
= 57: Key F28 to F0, only in forward direction.
= 58: Key F0 to F0, only in forward direction.
= 59: Key F1 to F0, only in reverse direction.
.....
= 86: Key F28 to F0, only in reverse direction.
= 87: Key F0 to F0, only in reverse direction.
= 101: Key F1-inverted to internal F0
.....
= 187: Key F0- inverted to internal F0, in reverse dir.
= 254: Directions Bit to internal F0, in forward dir.
= 255: Directions Bit to internal F0, in reverse dir.
Same as input mapping above for other functions:
CV #401 = 0: Key F1 to internal F1
= 1: Key F1 to internal F1
= 2: Key F2 to internal F1 and so on.
