: The system changes automati-

the two addresses = speed 0 and the other =speed >0.

Using this key (only on the main address), you can
switch between the main address of the decoder (on CV
#1 or CVs #17, #18) or the consist address.

activated automatically.
All ZIMO decoders are capable of operating on conventional layouts with DC power packs, including
PWM throttles, in
analog DC
as well as in
analog AC
(Märklin transformers with high voltage pulse for
direction change).
To allow analog operation,
CV #29, bit 2 = 1
must be set.
and
CV #12, bits 0 and/or 4 = 1
This is usually the case by default (CV #29 = 14, which includes bit 2 = 1), but analog operation may be
turned off in many sound projects (sound decoders).
The actual behavior during analog operation, however, is strongly influenced by the locomotive control-
ler (power pack). Especially in combination with a weak transformer, the track voltage may easily col-
lapse when the decoder (motor) starts to draw power which, in the worst case, leads to intermittent
performance.
In analog operation, it is possible to adjust the acceleration momentum (CV #14, bit 6) and function
outputs (CV #13 & #14) individually.

I.e. without acceleration and deceleration
according to CV #3 and #4.
Similar to a classical analog operation.
The
speed curves
There are two types of speed curves; between those select with
CV #29, bit 4
= 0
: 3-point speed curve (defined by 3 CVs)
... = 1
: 28-step curve (defined by 28 CVs)
3-point speed curve: the lowest, highest and medium speed are defined by CVs #2 (Vstart), #5 (Vhigh)
and #6 (Vmid) (=external speed step defined by slider position). This is a simple way to quickly estab-
lish a speed range and its curvature.
28-point speed curve (a.k.a..”freely programmable speed curve”): with the help of CVs #67 - #94, all
28 external speed steps can be assigned freely to the internal speed steps (0-255). These 28 CVs ap-
ply to all speed step modes (14, 28 and 128). If 128 external speed steps are used, the decoder adds
the missing intermediate values by interpolation.
ATTENTION
: DC analog will be implemented with SW version 4.50
NOTE
: Actual decoder settings may differ from the default values if a sound project is loaded.
