Accessory decoder
for Selectrix
®
for 8 turnouts, signals, uncouplers, relays
WDMiba 3
v5-2010
Degree of difficulty: easy
average
difficult
Required capabilities:
- Easy assembling and soldering of the PCB
The accessory decoder WDMiba is an output device for con-
trolling 8 turnouts, semaphores, light signals, uncouplers or
relays of a Selectrix-controlled model railway layout.
Solenoid based consumers (additional recovery diodes are
required!) are powered by pulsed current. Light signals are
powered by continuous current. To power accessories with
electric motors the extension kit ESMot has to be populated.
The accessory decoder’s SX bus address and its settings
(pulsed or continuous current) can be configured through SX
bus individually for each of the 8 output channels.
When (re-) powering the Selectrix bus, the accessory decoder
feeds back its last state (position of the turnouts etc.) to the
central unit.) before the system was switched off the last time.
Special features
- Especially for Selectrix
®
- Further improved reliability by using input comparators at the
SX bus
- Population option for motorized consumers already foreseen
(ESMot) – no additional PCB is required
- Space for series resistors for LEDs already included on PCB

Power Supply
The accessory decoder WDMiba requires a suitable external
power supply according to the requirements of connected acces-
sories.
The following values should not be exceeded:
Alternating current: 16V
Continuous current: 22V
Our transformer with 16V AC, 70W output is recommended.
Output current
Pulsed current: 2A each output, max. 4A combined
Continuous current: 1,5A each output, max. 1,5A combined
Connections
2s SX-Bus jacks
2x terminals for power supply
8x 3 terminals for 8 turnouts, light signals, etc.
Switch/Display
Push button and a status LED to switch to programming mode
Plugging to SX-Bus
The module is connected to the SX-data-bus via an (optional) SX-
bus cable.
For large layouts with long cables an additional ground wiring of
the SX-bus is suggested. Use terminal GND for that purpose.
Asynchronous rail and control bus may lead to flickering of the
occupancy detection. Increase response delay and dropout delay
to override this effect.
The module must never be connected to the Selectrix-Power-Bus
(PX-bus)!
Bus cables may only be plugged or unplugged at power down of
the model railway layout.
Assembly notes
The module is assembled following the instructions on the next
page. For soldering the components on the PCB a soldering iron of
12 to 25 Watts or a soldering station with the temperate set to
approx. 400°C is needed together with 0.5 or 1.0 mm soldering
wire with rosin flux. No special tools are required. Do not use
soldering flux! Pay attention to solder speedy to avoid device
damage by overheating.
Non-Use
When the module is not used it should be stored at a dry and clean
place.
The Instruction
The full content of the instruction is important. Very important
information is marked in colours; critical information is highlighted
in red. A recommended value for any setting is marked with an (*).
Installation site
The module should be located in a dry, ventilated and clean
area being easily accessible and lying beside or next to the
model railway layout.
The module must be kept free of coarse dirt or electro conductive
parts falling down.
The module may be arranged without a housing needed. In that
case the module shall be put on an insulating sub floor by means
of the plastic spacer rings and screws delivered.
Keep all electro conductive tools, assembly kits and cables away
from the module during operation.
A negligently and by external circumstances caused short-circuit
(impinging on the module from above or from the bottom) may
destroy the module. If that happens, all terms of warranty will
become invalid.
Update
The heart of the module is a PIC that stores the software. A socket
for the PIC provides easy access for the purpose of any software
update.
Never use other PICs than those dedicated to this module. Disre-
garding may lead to destruction of the module and all term of
warranty will become invalid.

Assembly instructions
Assemble the kit in the order of these instructions. All components are placed
on the top side of the PCB (marked “top”) as close to the PCB as possible
and soldered on the bottom side of the PCB (marked “Bottom”). Use a bend-
ing tool (e.g. Conrad 425869 – 62) for bending. Cut the leads of components
flush using a wire cutter after soldering.
Solder cleanly and precisely!

Populated PCB
1. Resistors
Bend the resistor leads for 7.5 mm pitch before insertion. To facilitate placing
components on the PCB support the edges of the board with the help of two
books, for instance, to leave enough space for the leads under the board.
Insert the resistors on board aligning the coloured rings of all the resistors in
the same way to make it easier to verify the value of the resistors later. Place
a suitable plane piece of wood or similar on top of the resistors on board. Turn
the board together with the wood upside down. The underside of the board is
now conveniently accessible for soldering the components.
Solder one end of each resistor first and check that they are positioned prop-
erly before soldering the other end of each resistor.
R1 - R3: 100Ohm (brown, black, black, black, brown)
R4 - R7: 4,7kOhm (yellow, lilac, black, brown, brown)
R9 - R12: 22kOhm (red, red, black, red, brown)
R13: 2,2kOhm (red, red, black, brown, brown)

(metallic shiny or black without marking)
facing the label “WDMiba v5-2010”, T11
to T18 (and T27 to T34) in the opposite
direction.
11. Rectifier
The rectifier has to be placed in the same height as the
transistors. Watch out the polarity.
B1 B80C1500
12. Electrolytic capacitors – Watch polarity!
The shorter lead is the negative pole and must be
facing to the right.
C5, C6: 47µF
C4: 1000µF
13. SX-bus jacks
Solder the shielding (big pads) of the jacks generously.
14. Verification and mounting the PIC
After soldering all components on the PCB verify once
more that they are placed according component layout
diagram and that they are oriented properly. Check that
all solder points on the bottom side of the PCB look
correct. Note especially if there are any undesired
solder bridges between solder pads.
After the verification the PIC can be mounted:
IC1: PIC ”WD3“
15. (Recovery diodes)
According to the drawing on the right,
the recovery diodes are soldered with
their cathodes (stripe) to the common
(b) pole.

Description of operation
Operating principle of the Accessory Decoder
The Accessory Decoder WDMiba permanently reads the informa-
tion of its dedicated address at the Selectrix-Bus and switches its
dual-port-outputs (one port for position “on”, one port for position
“off”) according to the given bus information.
Depending on the operation mode the outputs are set: For each
output, one of two timers can be assigned. According to the setting
of the timer used, the outputs are powered with pulsed current for
the time specified by the timer, or by continuous current.
Bringing into service
The address of the Accessory Decoder WDMiba, both timers and
the timer assignment for each output are programmed through the
SX bus. In order to do so, a controller, e.g. a central unit ZS1, a
controller unit SPF-PIC or a (bus)-interface with corresponding
computer programme are required.
After plugging Accessory Decoder WDMiba to the SX bus, these
parameters can be set.
During programming of the Accessory Decoder WDMiba the bus
addresses 0 to 3 will be used temporarily. That means during
programming the contents of these addresses will be changed.
Connection of solenoid accessory and light signals
The power supply voltage must be chosen to fit the requirements
of connected accessories:
Turnouts, semaphore signals and uncouplers with coils accept
maximum 16V alternating current. Light signals will need a some-
what lower voltage since the actual output voltage after the
smoothing capacitor of the rectifier circuit is 1.4 times the voltage
of the input alternating current. Light signals equipped with LEDs
designed for 16 V AC should be fed with either 11 V AC or the
value of the LED resistor should be increased respectively.
Output numeration of the Accessory Decoder WDMiba
Connections of output channels
Pin Tournout Signal Uncoupler
a: Tangent Stop Not used
b: + VS + VS + VS
c: Tournout Go Activate
Normal position for turnouts
The usual way is to connect turnouts with their normal position to
be the tangent position. If, however, the main line direction is in
turnout position, the turnout can be wired to the decoder accord-
ingly by swapping wires for turnout and tangent (a and b).
Turnouts wired in tandem
Using maximum two turnout motors wired in tandem is possible
and useful e.g. for hopping tracks. Make sure that the two motors
are identical.
Three-way turnout
A three way turnout
is wired like two
individual normal
turnouts connected
to two accessory
decoder output
channels. Before
switching to turnout
position, the oppo-
site side might have
to be switched to
tangent position.
Light signal
Set the decoder output channel for
continuous current. In order to avoid
too high voltage over signal lamps,
the common terminal (white) can be
alternatively connected to decoder’s
power connector for AC.
Light signal with train affection
Usually a remote control switch (relay) with two changeover
switches is used with light signals for train affection. Remote con-
trol switch is connected to the outputs of a decoder channel. The
switch controls signal lights and track current. Set the decoder
channel to operate in pulsed current mode for remote control
switches with or without end position detectors.

Connection of motorized turnouts
When connecting motorized turnouts, the
extension kit ESMot must be populated (for
the concerned outputs). Basically the connec-
tion of all motorized turnouts is the same: Both
contacts of the motor are directly connected to
the outputs of the Accessory Decoder
WDMiba, each at terminals a and c – terminal
b is left unconnected.
Some vendors of motorized turnouts equip their motors with an
additional circuitry (in most cases two diodes) which leads to more
than just two contacts. Usually there is one common ground (or
voltage supply) which is to be connected to terminal a. Additionally
there should be a contact for each turning direction which are to be
both connected to terminal c. There might be further wires but they
are not of interest for the connection to the Accessory Decoder
WDMiba.
Parameters and Programming
Programming
By programming the address of this module and all further pa-
rameters are set. In this section all parameters are explained.
Refer to the last page of these instructions for an example for the
programming procedure.
Convention Bit and Key
In information technology “Bit 0” to “Bit 7” is common.
For model railroaders a numbering of “bit 1” to “bit 8” is much more
convenient, as “Bit 1” becomes equal to “Key 1” or “position 1”.
This convention is used in these instructions.
Overview of parameters
Address 0: Address of this module 1 to 103 / 111 (80)
see table of addresses
Address 1: Timer assignment):
Bit value 0 (Off, “0” or “-“) assigns timer 1
Bit value 1 (On, “1” or “/”) assigns timer 2
Address 2: Timer 1 1 to 254, 255 (16)
Pulse length: 1 to 254: (80ms increments)
Continuous current: 255 (all bits 1)
Factory setting: 16 = pulse length 1.2 seconds.
Address 3: Timer 2 1 to 254, 255 (255)
Pulse length: 1 to 254: (80ms increments)
Continuous current: 255 (all bits 1)
Factory setting: 255 = continuous current
Address of this module
The address of this module can be set to any value in the range
from 1 to 111. Note that at certain central units addresses 104 to
111 are reserved for internal purposes during operation and should
thus not be used.
Also, addresses 0 to 3 are often used for programming parameters
of modules. Therefore these addresses should also not be used.
Operation mode
The Accessory Decoder WDMiba offers 2 operation modes:
Pulsed current and continuous current.
To allow controlling accessory types with different current require-
ments, for each of decoder’s eight output channels one of two
timers can be selected individually. Both timers (1 and 2) can have
either a pre-determined pulse length value or set to continuous
current.
Operation mode pulsed current
The operation mode pulsed current enables the output current only
for a specific time (set by the timer) after switching to this direction.
Afterwards, the output is off.
Not all solenoid powered accessories have the same requirements
for the duration of pulsed current to operate them. For instance, a
turnout with a double solenoid and limit stop can usually be oper-
ated with a 0.5 to 1 second pulse length. Theoretically it is possible
to operate this type of turnout with continuous current, but if the
limit stop is not working, the solenoid will get damaged. Solenoid
turnouts without limit stop should be controlled with pulses lasting
0.2 to 0.5 seconds.
On the other hand, there are slowly moving turnouts and sema-
phore signals. These might require pulse lengths of 4 to 8 sec-
onds.
Uncoupler tracks should as well not be operated with continuous
current. Instead, select a pulse with a length of up to 20 seconds
for uncouplers.
Operation mode continuous current
The operation mode continuous current enables the output current
permanently, so one of the dual-port outputs is always active.
For a light signal an output of continuous current is required which
lights up red on Stop but lights up green on Go instead. Only one
of the two lights is activated at the same time.
Timers 1 and 2
Both timers of the Accessory Decoder WDMiba are equal which
means that they can be programmed independently to any pulse
length between 0.08s (80ms) and 20 seconds with 80ms incre-
ments, by selecting values from 1 to 254. Both timers can also be
set to identical pulse lengths or continuous current mode (by pro-
gramming value 255).
For each of the 8 decoder output channels one of those 2 timers is
assigned.
Timer 1 is assigned for all output channels where operation mode
0 is selected; timer 2 is assigned for all output channels where
operation mode 1 is selected, respectively.
Overview of timers
The pulse length is calculated by summation of the separate bit
values (1 to 254) multiplied with the increment (0.08 s = 80 ms)
Bit 1 2 3 4 5 6 7 8
Value 1 2 4 8 16 32 64 128
Pulse 0,08 0,16 0,32 0,64 1,28 2,56 5,12 10,24
Value 255 (all bits ON) selects continuous current.
On the next page you’ll find a table with some examples.
Delayed output
In computer controlled and other automatic layouts several turn-
outs or signals are typically switched simultaneously. This could
result in excessive power consumption which exceeds the output
capacity of the decoder.
To prevent problems due to current peaks decoder outputs config-
ured for pulse type outputs are activated with 80 ms delay between
them when operated simultaneously. For channels set to continu-
ous current output, there is no delay between them in simultane-
ous operation.
Security monitoring system
Poorly laid wiring or malfunctions of system components may
result in a situation where a pulse type output is not switched off in
time. This can cause overheating or even burn a solenoid con-
nected to decoder output.
The Accessory Decoder WDMiba is equipped with a security
monitoring system (Watchdog) which cuts off the output current of
all output channels after about 2 seconds when an output pulse is
not terminated in time normally due to SX system malfunctions.
Factory default settings
Address of this module: 80
Operation mode: 0 0 0 0 0 0 0 0
(all output channels use timer 1)
Timer 1: 16 (1.28 seconds)
Timer 2: 255 (continuous current output)
If the address of this module is set to a value greater than 111, it
will be reset to the factory default setting (90).
Setting the address of this module to the value of 255 will reset all
parameters to their factory default settings.
Revert back to previous settings
Entering 0 as address, response or dropout delay reverts the
corresponding value to its previously programmed one.
