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 or RT2. These outputs are 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-DB_INFO_engl" onto your PC.
Programming the decoder address:
•
Switch on the power supply of your model rail way.
•
Activate the programming key S1. 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 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 the signal-aspects are combined into groups of
four. The address 1 to 4 build the first group. The address 5 to 8
build 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 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 (clamp2) 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 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.
GN1
Signal switching:
Below the drafts of the above 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 meaning of the signal position indicated
above or below. The addresses 1 to 4 are indicated as a sample only.
The actual addresses corresponds to the assignment you choose
during programming.
Have you connected an advance- and an exit-signal as per first sample
to one of the clamp blocks you can switch the exit-signal to proceed
(Hp1) with the address 1 and the key green.
The light emitting diode marked with GN will now indicate this at the
signal.
Dark switching:
In case an advance- and an exit-signal is on one common signal
post the advance-signal has to remain dark if the exit-signal
indicates STOP (Hp00) or proceed shunting (Sh1).
To activate the dark-switching-mode switch the home signal to Hp00
or Sh1. If you now press the key 4 'red' you can switch the advance-
signal-aspect to 'on' respectively to 'off' with each keystroke. If the
GN1
advance-signal is in 'off' position the dark-switching mode is activated.
The light signal decoder stores this mode permanently as well as
the programmed addresses. All programmed modes can be changed
at any time.
Advance signal commands received during the signal is switched to
dark will be indicated when the exit signal will be switched to Hp1 or
Hp2.

The Light signal decoder LS-DEC switches the signal aspect 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.
