Introduction/Safety instruction:
You have purchased the Light-signal decoder LS-DEC-DR 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 a 2 years limited 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, Intellibox, TWIN-CENTER, ECoS,
EasyControl, KeyCom-DC and Arnold-Digital / Märklin-Digital=
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,
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 directly
to the command station or a booster 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).

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 block. 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 10mA.
This provides sufficient brightness. In case your light emitting
diodes are to bright you can correct the brightness by assembling
external resistors of some 100 Ohms to your personal requirement.
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.
Further sample connections are available at the internet on our Web-
Site (www.ldt-infocenter.com) under "Downloads". Please load the file
"LSDEC-DR_INFO_engl" onto your PC.
Programming the decoder address:
•Switch-on the power supply of your model rail way.
•Activate the programming key S1. Do not touch the integrated
circuits of the pc-board because any electrostatic discharge can
destroy the IC`s.
•At least two light emitting diodes on a signal connected to the
left clamp block will be automatically switched over every 1,5
seconds in a flashing mode. This indicates that the decoder is in
the programming mode.
•Press now one key of the key-group to be assigned to the left
clamp block of the decoder. For programming the decoder address
you can also release a turnout switch signal via a personal
computer.
Remarks: The decoder addresses for magnet accessories also
to be used for switching the signal-aspects are combined into
groups of four. The address 1 to 4 will be the first group. The
address 5 to 8 will be the second group etc. Each clamp block of a
LS-DEC decoder can be assigned to any of these groups. It does
not matter which of the eight possible keys used for programming
will be activated. The decoder stores always the complete group of
keys.
If the Light-Signal Decoder LS-DEC shall control main-and
advance signals or main-light signals this has to be adjusted
together with the decoder address. If you activate within the
programming mode one key of the desired group of four keys
designated for switching a turnout straight or a signal to green the
decoder will be set for controlling of main-and advance signals.
If you activate a key for switching a turnout round or a signal to red
you have selected the option to switch main-light signals. It is
essential to activate for both programming settings (left and right
clamp bar) both either a red or a green key.
•If the decoder has recognized the assignment correctly the
connected light emitting diode will flash a little faster. Afterwards
the flashing slows down to the initial 1,5 seconds again.
In case the decoder will not recognize the address it could be that
the two digital information connections (clamp 2) are wrong
connected. For testing this, switch off the power supply, exchange
the connection on KL2 and start addressing again.
•Press now the programming key S1 again. At least two light
emitting diodes connected to the right clamp block will flash now.
Repeat the programming for this clamp block as described above.
•Now press the programming key S1 a third time for leaving the
programming mode. All signals will be automatically switched to
STOP.
Signal switching:
Below the above drafts of signal aspects you can find a respective key-
group for the addresses 1 to 4 and the corresponding keys 'red'and
'green'.Additionally is the signal aspect assigned to the respective key
indicated above or below. The addresses 1 to 4 are indicated as a
sample only. The actual addresses are corresponding to the
assignment you have selected during programming.
If you have selected during programming the light-signal decoder for
the switching of main-and advance signals as shown at the upper
draft you can switch for example with the address 1and key green the
main signal to proceed (HI 1).
The light emitting diode marked with GN will now indicate this at the
signal.
If you have set the decoder during programming the addresses for
switching main-light signals you should refer to sample 2.
For the main signal is it possible to set a total of 14 signal aspects.
How to realize this with only 8 keys (4 addresses) shows the key
occupation below the signal. After switching-on the main-light signal
shows HI 13. If now e.g. HI 1shall be shown at first the address 4with
green key and then address 2with green key shall be activated.
Only bold framed keys are required for switching the signal.
Is the main-light signal equipped with a substitute-red light emitting
diode you can connect either the light emitting diode main-red or
substitute-red to RT 1 of the clamp bar on the Light-signal decoder.
Light bars:
The light-signal decoder LS-DEC-DR supports as well light bars. You
can decide if you connect the green light bar to indicate with HI 2
(travel speed 100km/h) or leave it to indicate with HI 3a (travel speed
40km/h). Just as well you can connect the yellow bar to indicate with
HI 3b (travel speed 60km/h) or leave it to indicate with HI 3a (travel
speed 40km/h).
If your DR-signal contains light bars with serial light emitting diodes
(models of manufacturer Erbert) you require the adapter Adap-LS.
Attention:
The Light signal decoder LS-DEC switches the signal aspects not just
on and off but is dimming the light emitting diodes realistic up and
down. Even between the signal aspects a short off-phase is provided.
Further digital commands received during this switch-over-time of about
0,4 seconds will not be taken up from the decoder. Please take care
that the switching-commands are not in a to fast sequence. The
impression is absolutely realistic if the switching is considerable slow.
