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 12 and 29 in the PIKO SmartDecoder XP 5.1. 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 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.
mfx
®
PIKO SmartDecoder XP 5.1 is specifically made for the mfx® data format. If your control system uses the mfx®
format, then the decoder is automatically recognized and is assigned its locomotive symbol, decoder address, and
its up to 16 special function symbols. With mfx® technology, no locomotive data has to be stored in the central
control unit and no locomotive addresses have to be programmed into the decoder.
Braking
The 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 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
Easy-to-use
function mapping
allows you to assign functions like lighting and other outputs to any key between
F0 – F12. Acceleration, braking delay, and switching (shunting) mode can be assigned to any function keys using
CVs 156 and 157.
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 decoder can control up to two servo motors via outputs A6, A7. Function key assignment is done exclusively via
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.
Factory reset
To restore the 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
SmartControllight DCC system, the PIKO SmartControl DCC system, or any other DCC- and Motorola based systems.
For more information on programming options, please refer to the instruction manual.
