Bit 5
DC stopping
Bits 0, 1, 4 &6 = 1; that is CV #124 = 83.
Bit 5 = 1:
”DC stopping“
#155
Half-speed key
selection
0 - 28
0
Expanding on the settings of CV #124; if another key
is required than F3 or F7:
CV #155: Defines a function key for half-speed activa-
tion (= top speed cut in half).
If a key is assigned through CV #155, a possible as-
signment through CV #124 is void.
CV #155 = 0 doesn’t mean that the F0 key is assigned
but rather that the setting in CV #124 is active.
#156
Momentum-
deactivation key
selection
0 - 28
0
Expanding on the settings of CV #124; if another key
than F3, F4 or MAN is required for momentum deacti-
vation:
CV #156: Defines the function key that deactivates or
reduces the acceleration and deceleration times in
CV’s #3, 4, 121 and 122.
Whether the momentum is deactivated or reduced and
by how much is still defined in CV #124:
CV #124, Bit 1, 0:
= 00: no effect on momentum
= 01: removes momentum of
CV #121 + #122
= 10: CV #3 + #4 reduced to ¼.
= 11: removes all momentum.
In order to deactivate all momentum, CV #124 is
typically set to a value of 3 (the value may be different
if other Bits in CV #124 are also set).
A possible key assignment for momentum deactivation
in CV #124 remains inactive if CV #156 > 0.
#157
Selects a function
key for the MAN
function
Only needed for non-
ZIMO
cabs that don’t have
the MN key.

The MAN function (or MAN key on ZIMO cabs) was
originally designed for ZIMO applications only, in order
to cancel stop and speed limit commands applied by
the signal controlled speed influence system (HLU).
This function was expanded in later software versions
to include “asymmetrical DCC signal stops” (Lenz
ABC).
If ZIMO decoders are used with non-ZIMO systems, a
function key can now be assigned with CV #157 to
cancel a signal controlled speed limit or stop com-
mand.

The NMRA-DCC function mapping
ZIMO large-scale decoders have 8 or 14 function outputs (FO). The loads connected to these
outputs (head lights, smoke generators, etc.) are turned on or off using the function keys on
the cab (throttle). Which function key controls which function output can be specified with the
NMRA function mapping
CV‘s #33 to #46
Unfortunately, this function mapping also has its limitations (only one 8-Bit register is available
for each function, which leaves only 8 outputs to select from) and the headlight is the only
function that can switch with direction.

The black dots in the table above indicate the default settings at the time of delivery, where each
function key corresponds to the same numbered function output. Therefore the following values
were written to the configuration variables:
CV # 33 = 1
CV # 34 = 2
CV # 35 = 4
CV # 36 = 8
CV # 37 = 2
CV # 38 = 4
CV # 39 = 8
CV # 40 = 16
CV # 41 = 4
etc.
