Motorola
®
The decoder utilizes 4 Motorola® addresses to access functions F1 - F 16, when using a Motorola—based
command station. The three sequence addresses for the functions F5 - F16 are ascending to the decoder address
and can be activated in CV61 as required by the values 1 (F5 - F8), 2 (F5 - F12), or 3 (F5 - F16).
Configuration of CVs
CVs 12 and 29 control the operating mode and configuration CVs, respectively. As a rule, an indexed CV contains
various basic settings of a decoder, such as reversing the direction of travel. CV calculation examples can be found
in the detailed operating instructions.
RailCom

, RailCom Plus
®
In the sound decoder, CV29 (RailCom®) can be turned on or off via bit 3. The decoder is automatically recognized
by RailCom Plus® - equipped command stations (like PIKO SmartControl) if the RailCom Plus® option is activated
in CV 28. The decoder name, locomotive symbol, and special function symbols will appear automatically on your
control device’s screen. With RailCom Plus® 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.
mfx
®
The PIKO SmartDecoder XP 5.1 Sound also masters the mfx® data format. If the digital control unit used is mfx®
capable, the sound decoder automatically registers with its locomotive symbol, decoder name and its special
function symbols. This mfx® technology means that no locomotive data has to be stored in the command station
and no locomotive addresses have to be programmed into the sound decoder.
Braking
The sound decoder understands the following braking methods:
Märklin® braking section (brakes with analog DC voltage)
DCC braking function
ABC (Automatic Brake Control) braking section
The decoder’s adjustable braking distance can bring the train to a stop within a centimeter of a signal. More
information on "braking behavior" can be found in the detailed operating instructions for
PIKO SmartDecoder XP 5.1 Sound.
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
In the
simple function mapping
(CVs 33 - 46) the assignments of the switching tasks like lighting and special
function outputs can be freely assigned to the function keys F0 to F12 of the digital central unit. The switchable
acceleration, braking delay and the shunting mode can be assigned to any function keys in CVs 156 and 157. More
detailed information can be found in the detailed operating instructions.
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.
Function key assignment is done using extended function mapping.
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. With the appropriate decoder settings, function outputs A4
and A5 will automatically switch off after a user-adjustable time without having to press their function 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..
Extended function mapping
Due to its complex nature, extended
function mapping
cannot easily be set by programming individual CVs. To
work with extended
function mapping
, you will need the PIKO SmartProgrammer device (#56415) and, if desired,
the PIKO SmartTester (#56416). Detailed information on extended function mapping is available in the instruction
manual.
Servo control
The sound decoder enables the control of servo motors via all function outputs. The assignment to the function keys is
done exclusively via the extended function mapping.
The use of a servo with the decoder requires electronics expertise.
Further information can be found in the detailed operating instructions.
ATTENTION:
Soldering on the decoder should only be carried out by experienced specialists with the appropriate tools.
Decoders damaged by improper handling will not be covered by the warranty.
Sound settings
To change the overall sound volume of the SmartDecoder XP 5.1 Sound, first program CV31 to a value of 16 and CV32 to
a value of 0.
This will take you to the programming area for setting the total volume. You can now set this as you wish in CV257 in the
value range 0 - 255.
NOTE: In order to play a PIKO sound on the sound decoder, the test and programming device requires PIKO
SmartProgrammer (#56415) and (optional) the PIKO SmartTester (#56416).
All further information about the sound section of the PIKO SmartDecoder XP 5.1 Sound as well as the available
For setting options, please refer to the detailed operating instructions.
Factory reset
To restore the sound decoder to its factory settings, program CV8 to a value of 8.
Programming
Configuration variables (CVs) form the basis of all the decoder’s settings. This decoder can be used with the
PIKO SmartControl
light
DCC system, the PIKO SmartControl DCC system, or any other Motorola-based system.
For more information on programming options, please refer to the instruction manual.
