PIKO SmartDecoder XP Sound - Decoder Configuration and Operation Modes; Motorola and Configuration CVs; RailCom and RailCom Plus; mfx Compatibility

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).
Conguration of CVs
CVs 12 and 29 control the operating mode and conguration CVs, respectively. For the vast majority of DCC users,
there should be no need to change the factory defaults. An indexed CV generally contains various basic settings of
a decoder, such as travel direction. See the detailed decoder instructions for further info.
RailCom
®
, RailCom Plus
®
This decoder will be automatically recognized by DCC systems equipped with RailCom Plus® technology. The
decoder name, locomotive symbol, and special function symbols will appear automatically on your control device’s
screen. No locomotive data needs to be stored in the DCC central station and no different addresses need to be
programmed into the decoder. RailCom Plus® can be turned off and on via CV 29 bit 3.
ts mfx®
The PIKO SmartDecoder XP Sound also masters the mfx® data format and is “ts mfx®” certied. If the digital
command station used is mfx® capable, the sound decoder automatically registers with its locomotive symbol,
decoder name and its function symbols. No locomotive data needs to be stored in the command station and no
different addresses need to be programmed into the decoder.
Braking
The sound decoder understands the following braking methods:
Märklin® braking section (brakes on 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 decoder 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
Easy-to-use function mapping allows you to assign functions like lighting and other outputs to any key between F0
and F12.
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). This is only recommended for advanced DCC users.
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 Sound, rst 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).

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
Conguration variables (CVs) form the basis of all the decoder’s settings. For more information on programming options,
refer to the detailed decoder instructions.
