1. Important Information
The manual is a guide to assemble the SKD224 replacement
board and gives some decoder setting recommendations and
programming tips. The replacement board is a drop in replacement
for the original board situated inside the SKD locomotives chassis.
The replacement board contains a DCC decoder and a Smart
Power Supply (SPP) and is suitable for DCC operation. The
decoders have installed a dedicated firmware with factory default
parameter values optimized for the SKD224 locomotives. After a
decoder reset, all the decoder parameters are reverted to the factory
default values.

4. Operation principle
The SKD224 replacement board contains a smart power pack (SPP)
and is integrating a DCC decoder with BEMF PID motor control and
4 physical (function) outputs. The decoder controls the charging of
the on board 1 Farad capacitor, and ensures switching to the internal
power supply in case of track contact interruption. This guaranties a
trouble free running of the SKD224 even if the contact with the rails
is lost. The SPP is capable to power the locomotive up to 4 seconds
and can run it up to 30-50 centimeters without DCC power
(depending on the speed). This is especially useful for small 2 axle
locomotives like the SKD224, which has only a few current pickup
points, and suffer very often of DCC power interruption.
At start-up, the board will have a current consumption of 250-300
mA for up to 2 minutes, even if the locomotive is stationary. This is
normal, during this time the SPP is charging the internal capacitor.
In case of external power interruption, after the maximum allowed
timeout has been elapsed (this can be changed altering the specific
CV), the locomotive will stop. The operation can be resumed when
the locomotive is powered again over the rails.
Due to the operational principle, the SPP can be used only in DCC. If
the locomotive is used in DC, the SPP will be not activated.
The lights of the SKD224 are wired to the internal SPP circuit, so
even in the case of contact problems while running, during the
switching between external DCC power and internal SPP, the lights
are stable, and no annoying dimming is visible.
Connections for optional front/rear lights and electrical couplers are
available at both ends of the boards.

The on board decoder is full of options: is featuring a SUSI
connector for optional sound module connection, contains Zero
Speed and ABC Braking, with penduling (push-pull operation), has
a RailCom transmitter, and is capable of driving different electrical
couplers. Future options can be also integrated with a firmware
upgrade.

Note 1: The positive common terminal for the optional lights
(brown color in the illustration) is not the same as the coupler
positive common (blue in the illustration). It is forbidden to
connect them together.
The front/rear light outputs (white and yellow color) allows
direct connection of LEDs, so no current limiting resistors are
needed. The resistors are integrated to the boards. The Anode
of the LEDs must be connected to the Lights Common, while
the cathode to the front/rear outputs.

Remove the 2 original axles with the plastic toothed wheels from the
chassis. The axle’s assembly keeps the current pickups pressed to the
wheels, while removing them the current pickups will depart from
the chassis.
At this point since there is access to the gearbox, it could be a good
idea to apply some grease over the wheels if needed. However, this
can be done at a later time too. You can use Roco type grease part
number 10905.

In the illustration an exaggerated quantity of grease is applied for
exemplification. Use the grease in a moderate quantity.
Apply it also on the intermediary toothed wheels too.
Insert the replacement axles with the brass toothed wheels. They
must be inserted starting from the inner side of the chassis (1),
moved to the correct position (2) while pressing the elastic current
pickups to touch the wheels from their inner side (3).

9. Decoder settings
The factory default setting maps the F0 function direction dependent
to the front and rear lights (FL and RL), and the F1 function to the
cabin light (AUX1/Out3).
FL front side high beam reflector (Out1)
RL rear side high beam reflector (Out2)
AUX1 cabin interior light (Out3)
AUX2 Not Used by default, connected
to the optional electrical coupler
outputs at both ends of the board (Out4)
The light intensity of the front/rear side high beam reflector and the
cabin light can be changed in CV48-49-50. In the factory settings,
these are configured for maximum intensity.
The decoder is preset for 28/128 speed step operation, no dc mode.
To take the full advantage of the BEMF motor control, we
recommend driving your locomotive with 128 speed steps. The
RailCom transmitter is sending the locomotive address in broadcast
mode. By default, the following function mappings are valid:
F3 shunting speed
F4 acceleration / deceleration OFF
F5 constant braking distance OFF
These mappings can be changed by altering the CVs 33-47. The
stopping configuration (CV27) by default has active only the Zero
Speed Brake option. Electrical coupler, ABC braking and penduling /
push-pull operation is disabled.

10. Programming tips
The SPP timeout is set by default to its maximum value 255, which
results in a ~ 4 second autonomy of the decoder in case of a DCC
power failure. This is useful, but has it’s withdraw: the locomotive
will be uncontrollable till this time expires. To avoid this, the SPP
timeout settled in CV123 can be decreased till a convenient value.
The Output4 (AUX2) of the decoder can be used for switching an
optional electrical coupler. First of all, we have to map a function to
this output (CVs 33-to 47). For example mapping F6 for the
electrical coupler will be made by changing the CV41 from the
default 0 value to 8.
Then we have to activate the coupler effect on the Output4 (AUX2).
This will be done by specifying in CV118 the Output4. Write in
CV118 the value 4.
The electrical coupler effect can be configured for only pwm action
(CV124=0, default value), or for some specific couplers which need
a full powered drive signal for a certain amount of time, and pwm
after the coupler is activated (CV124=1).
During the coupler operation the locomotive can be configure for the
typical “waltzer” (back, kick, and forward) movement. The back
movement and kick time is specified in CV119, while the forward
moving time and speed in CV120 and CV121. The settings of these
CVs can be done in several iterations by trial. During this coupling
operation the directional headlights of the locomotive will be not
switched. This “waltzer” movement is valid only if one of the 4
outputs is configured for coupler effect.
The Constant Braking Distance (CBD) is active by default (CV27
bit7 = 1). This will be taken inconsideration if the Zero Speed Brake
(active by default) or ABC braking (inactive by default) is requested.
Page 27
SKD224 replacement board
Assembly Manual
Document
Version
0.1.6
Page 27 of 46
The stopping distance should be determined at maximum speed step.
This can be done by altering the default 3 value of CV137 to 1,
which means the shortest possible stop distance (this distance
depends on the locomotive mechanical construction and gear box
configuration). This can be increased using a higher value for
CV137, and/or applying a braking delay in CV138. CV138=0 means
no braking delay applied over the stopping distance. These setting
must be done in several iteration by trial and error. In braking
condition, the locomotive will decelerate according to the constant
braking distance, and not base on CV4 (deceleration rate). However,
changing the speed of the locomotive (not to zero speed) will use the
deceleration rate settled in CV4. The constant braking distance can
be switched off with the F5 function (default configuration). The
function mapping can be changed altering CV116.
The stopping condition of the locomotive can be requested with the
help of ABC braking modules. The activation of this option is made
in CV27, bit0 (on right rail) and bit1 (on left rail). Either one or both
of these options can be used. If there is an uncertain situation while
detecting the ABC sections, the sensitivity of the ABC braking sector
detector can be increased by higher value than the default 15 in
CV134. Combining the ABC braking with the constant braking
distance will stop your locomotive in an exact position.
The locomotive can perform a so called penduling / push-pull
operation. For doing this, two braking sector must be present at both
ends of a straight track. The ABC braking must be configured in
CV27 for both directions (right and left rail too). The locomotive will
run from end A to end B of the track, where it will detects the
braking condition, will stop, and will wait till the waiting time
specified in CV133 will elapse. Then it will start to run in reverse
direction till it reaches end A, where it will stop again, wait, and so
on. If during this operation a new speed step command is sent to the
decoder from the central station, it will override the penduling

Page 28 of 46
operation, and the locomotive can be controlled manually. If the
constant braking distance is active during the penduling operation,
the stopping of the locomotive at A/B ends will be done according to
the specified braking distance.
11. Analog operation
The analog operation of the SKD224 replacement board is not
activated by default to allow the operation of the SPP circuit.
However, the activation of the DC operation can be made by altering
the default CV29 value. Changing CV29 from the default value of 10
to 14 will activate the DC operation, but in the same time it will
deactivate the SPP.

13. CV Table
In the table below you will find the complete list of configuration variables (CVs) of the DCC decoder
built in the SKD224 replacememt board. We recommend to change the default values only if you know their
function. Wrong settings can have negative effect ower the performance of the locomotive, or can cause nonexpected actions to the DCC commands sent by the command station. The CV No. column contains the
number of the configuration variables, while the Value Range contains the valid range of values for each of
the CVs. The Default Value column contains the factory default values for each CV optimised for the
SKD224 (after performing a decoder reset each CV will contain this value). The Description column will
give you a brief description of each of the CVs. To perform a decoder reset (in case of wrong CV settings)
please write any numerical value to CV8.

Brake Delay Configuration
CV138= 0 means no Brake Delay. To increase breaking distance above the
value configured in CV138, increase in small amounts the value of CV65,
which will delay the start of the braking, resulting in a longer braking path.
Brake Delay = CV138 Value * 8ms (ms)
Extra Distance = MaxSpeed * BrakeDelay
Ex: 200ms(delay)=8(ms)*25(CV value)
