Simple and extended function mapping
With simple function mapping, adjustable func-
tions like lighting, special function outputs, switching
(shunting) mode, and acceleration and braking can
be freely assigned to function keys F0 to F12 of the
DCC central control unit. For more information, 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
decoder 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 uncouplers
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 necessary. 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 pro-
gramming after a reset, you can select beforehand
which areas of the decoder programming should be
reset to factory values. To restore the basic func-
tions 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.

In the event of a defective decoder, please return
the decoder module to PIKO along with proof of pur-
chase, the decoder address, and a short description
of the problem.
Warranty Statement
Each decoder module is fully tested before
shipment. Nevertheless, should a malfunction occur
within the 2-year warranty period, we will repair the
module free of charge on presentation of the proof
of purchase. This warranty is voided if the unit has
been damaged by improper use. Please note that,
according to the German Electromagnetic Compat-
ibility Law (EMV Gesetz), the decoder module may
only be used inside models bearing the CE mark.
