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
In addition to the decoder address, the indexed CVs of a locomotive decoder are the most important CVs. These are
the CVs 29, 50 and 51 in the PIKO SmartDecoder XP 5.1 Sound. 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. If RailCom Plus® is turned on, the
decoder will be automatically recognized by a RailCom Plus®-enabled DCC control system (i.e. PIKO SmartControl)
and a locomotive icon, decoder name, and its special function icons will appear on the control system’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.
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 sound 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 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 gear 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 the outputs A1 and A2, which is controlled by the sound decoder load-
dependent (factory setting) or also speed-dependent. The assignment to the function keys is done exclusively via
the extended function mapping.
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 the function outputs A1 and A2. 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.
