control unit and no locomotive addresses
have to be programmed into the decoder.
mfx ®
The PIKO SmartDecoder 4.1 G is specifically
made for the mfx ® data format. If your
DCC control system uses the mfx ® format,
then the decoder is automatically recog-
nized and is assigned its locomotive
symbol, decoder address, and its special
function symbols. With mfx ® technology,
no locomotive data has to be stored in the
DCC central control unit and no locomotive
addresses have to be programmed into the
decoder.
Braking
The decoder understands the following
braking methods:
• DCC braking function
• Märklin braking section (brakes with
analog DC voltage)
• ABC (Automatic Brake Control) braking
section
The decoder can stop the model with
two adjustable braking distances that are
accurate down to the centimeter. More
information on „braking behavior" can be
found in the detailed operating instructions.
Function outputs
A comprehensive description of all options
related to the function outputs can be
found in the detailed operating instructions.
Simple and extended function mapping
With simple function mapping, adjust-
able functions like lighting, special function
outputs, switching (shunting) mode, and
20
acceleration and braking can be freely
assigned to function keys F0 to F12 of the
DCC central control unit. For more informa-
tion, refer to the CV table at the end of this
manual, as well as the detailed user guide.
Smoke generator control
A smoke generator can be connected to
outputs A1 to A7 which are load-sensitive
and react to the model's speed.Electric
coupler control
PIKO electric couplers are operated by tiny
copper wire resistance wires which heat up
when the decoder sends current through
them. The heat causes the wires to expand,
causing the coupler hook to move to the
uncoupled position. The model can then
back away from the car. The model's de-
coder can be programmed to automatically
shut off current to the coupler mechanism
after a certain time period, without need to
press another key.
Switching (shunting) scenario, remote
coupling/uncoupling
If your layout has remote electric un-
couplers installed, you can program the
locomotive decoder to perform a switching
scenario like the following:
1) The locomotive runs in one direction for a
certain distance.
2) The locomotive stops and reverses
direction.
3) The locomotive uncouples and moves
back from the uncoupled car for a certain
distance.
4) The locomotive stops, and resumes
switching.
For information on extended function
mapping, refer to the detailed operating
instructions.
Servo control
The decoder can control up to four servo
motors via outputs. Further information
can be found in the detailed operating
instructions.
Factory reset
CAUTION! When the decoder is reset,
all factory settings are erased! Only
perform a reset if it is absolutely neces-
sary. If you nonetheless have
to reset the decoder remember that
functions programmed at the factory
may no longer function and you must
reprogram the individual Function
Mapping (see FAQ)
To restore the decoder back to factory
settings, use CV8 for DCC programming and
CV59 in Motorola programming. To avoid
having to re-enter all programming after a
reset, you can select beforehand which ar-
eas of the decoder programming should be
reset to factory values. To restore the basic
functions of the decoder, enter a value of
1 in the Reset CV (8 or 59). Information on
extended reset can be found in the detailed
operating instructions.
