Introduction/Safety instruction:
You have purchased the Light-Signal Decoder LS-DEC-BR for your
model railway as a kit or as finished module.
The LS-DEC is a high quality product that is supplied within the Digital-
Professional-Series of Littfinski DatenTechnik (LDT).
We wish you having a good time using this product.
The Light-Signal Decoder LS-DEC of the Digital-Professional-Series
can be easily operated on your digital model railway.
By using a connector plug bridge you can choose if you want to
connect the decoder to a Märklin-Motorola system or to a digital system
with DCC standard.
The finished module comes with 24 month warranty.
• Please read the following instructions carefully. Warranty will expire
due to damages caused by disregarding the operating instructions.
LDT will also not be liable for any consequential damages caused by
improper use or installation.
Connecting the decoder to your digital model railway
layout:
• Attention: Before starting the installation-work switch off the
layout voltage supply (switch-off the transformers or disconnect
the main supply).
The Light-Signal Decoder LS-DEC is suitable for the DCC data format
as used e.g. by Lenz-Digital Plus, Roco-Digital (switching via
Keyboard or multiMAUS only; switching via Lokmaus 2® and R3® is
not possible), Zimo, LGB-Digital,
DiCoStation, ECoS, EasyControl, KeyCom-DC and Arnold-Digital /
Märklin-Digital= respectively Central
whenever no connector plug bridge is inserted in position J2.
The decoder is suitable for Märklin-Digital~ / Märklin Systems or
Märklin-Motorola (e.g. Control-Unit, Central Station, Intellibox,
DiCoStation, ECoS, EasyControl, KeyCom-MM) if you insert a
connector plug bridge on J2.
The decoder receives the digital information via the clamp KL2.
Connect the clamp with a rail or even better connect the clamp to an own
digital main ring supply assuring the supply of digital information to be
free from any interference.

Please attend to the marking on clamp KL2. The colors 'red' and 'brown'
next to the clamp are usually used by Märklin-Motorola systems (e.g.
Märklin-Digital~ / Märklin Systems / Intellibox DiCoStation / ECoS /
EasyControl).
Lenz-Digital systems are using the letters 'J' and 'K'.
In case you assemble the decoder to an Arnold-Digital (old)- or
Märklin-Digital= system, you have to connect 'black' to 'K' and 'red' to
'J'.
The decoder receives the power supply via the two poles clamp KL1.
The voltage shall be within a range of 14...18V~ (alternate voltage output
of a model rail road transformer).
If you do not want to supply voltage separately from a transformer to
the LS-DEC decoder you can connect the clamp KL1 to clamp KL2
with two wires. In this case the decoder will get the power supply
completely from the digital network.
Connecting the signals:
General:
Up to 4 signals can be connected to the Light-Signal Decoder LS-DEC.
Two signals per each 11poles clamp bar. The connection sequence of
the two clamps is identical. The following description refers mainly to one
clamp only. As you can see at the identical markings the description is
also valid for the second clamp.
Common connection:
All LED-signals of any manufacturer are designed in accordance to the
same principle. One wire of all light emitting diodes of a signal will be
generally connected to a common cable. Depending if all anodes or all
cathodes are connected together the signals will be called as common
anodes- respectively common cathodes-signal.
If you use signals with common anodes you have to clamp this cable to
the connection marked '+'. In addition you shall not insert the
connection plug bridge in J1 in this case. If you use signals with
common cathodes you have to clamp this cable to the connection
marked '-'. In this case you shall insert the connection plug bridge in
J1.
The second connection of each light emitting diode is separated and
mostly color marked at the end and contains a series resistor.
Series resistors:
Light emitting diodes have always to be operated with a suitable
series resistor to prevent that they will be destroyed. For this prevention
all outputs contain already a series resistor of 330 Ohm integrated on
the printed circuit board of the Light-Signal Decoder LS-DEC. Is there
no further external resistor available the diode-current will be about
10 mA. This provides sufficient brightness.
For assigning the single cables of the light emitting diodes to the
correct clamp connection please attend to the below signal images.
The marks next to signal light diodes are not corresponding to the
actual light-color but to the marking of the connection at the Light-
Signal Decoder LS-DEC.
If you do not know the correct allocation of the single wires to the light
emitting diodes you can test the function by connecting the wires to
clamp RT1. This output is active because the decoder switches all
signals to red after switching on.
