Accessory Decoder LS 100/110 1
DIGITAL plus
Accessory decoders are the link between your NMRA DCC
system and your function devices (that is turnouts, signals,
uncouplers, etc.) on your model train layout.
Accessory decoders receive commands sent from the command
station via the power station and activate the drives of turnouts
or other switching devices. For DIGITAL plus systems these
switching commands are activated from input devices, such as,
hand held controller LH100, tower cab LW100, interface LI100 or
translation module LC100 (in connection with another,
compatible digital system).

Whats new in the upgraded LS100/110?
A push button and an LED have been added to the
LS100/110 to make programming easier. Direct CV mode is
now supported in service mode and a selectable flashing rate
has been added.
LED:
Whenever the LS100/110 has received information destined
for it, the LED will light up for a certain amount of time. This
allows you to very easily verify that your LS100/110 is
receiving information, and thus is correctly connected. If you,
for instance, have called up the turnout address on the hand
held controller and press the + or - keys, and keep them
pressed, then the LED will flicker or stay lit. If you release the
key, then the LED will also go out again. If this is not the case,
then you may have selected the wrong address on the LH100,
or the connection from the LV101 to the LS100/110 is not
correct.
The LED is also used as a display during programming with
the push button.
Push button:
The push button allows you to reprogram the address of an
installed LS100/110. You can also reset it to the factory
settings. The LED here serves to indicate the programming
process.
Selectable flashing rate:
In the previous version, the flashing rate was permanently
preset to 2 Hz. Now you have a range of 4 to 0.5 Hz.
available.
Special note
Accessory decoders LS100 and LS110 share this operation
manual. Unless noted, the text applies to the LS100 as well as
LS110. When describing features, connections, operational
steps, etc. that apply to only one of the accessory decoders,
only the decoder in question is named.

Specifications of LS100/LS110
Up to 4 function devices each with a twin output can be
connected to each LS100/LS110. Power for these function
devices can by supplied by the track power or through an
external power supply. Each function device output can have its
characteristics individually set (by programming). In this way you
can program each output with a variable pulse duration, a
variable flashing operation or to a constant operation,. This
allows the direct connection of lightbulbs or LEDs without
additional relays.
The LS100 also has a connection for the feedback bus of the
DIGITAL plus system. If the feedback bus is connected, then the
position of turnouts can be sent back to the system when using
suitable turnout drives. It is then possible to display a turnout
being thrown by either DCC or by hand.
Electrical specifications:
Supply voltage:
8 - 18V AC or pulsing DC
8 - 25V pure DC (battery, lab power supply).
Current load capacity:
individual
output: 1.7A continous,
3 A peak (max. 20 sec.)
whole
decoder: 1.7A continous, as the sum of all
outputs.
3A peak (max. 20 sec.)
More about settings the outputs
Pulse output:
Pulse output means that the output is on (active) for at least as
long as a switching command is sent to LS100/LS110. The
switching command is for example sent to LS100/LS110 as
long as you keep the ‘+’ or ‘-’ key pressed on LH100.
The time that the function device output remains active after
releasing the key—the pulse duration—is determined by a
programmed numeric value. If during the activation time of this
4Accessory Decoder LS 100/110
pulse duration a new switching command is received by the
LS100/110, the output remains active for another pulse
duration.
Constant output:
By pressing the ‘+’ key on the LH100, the function device
output + is activated and remains active until the ‘-’ key is
pressed at which time the - output is activated. Thus either the
+ or - terminal of an output is active, the output operates as a
toggle switch:
For example, if you were to connect a red lightbulb of a signal
to an output’s + terminal, and the green lightbulb to the -
terminal, then when you press the ‘+’ key, the red lightbulb will
be on (the signal shows ‘stop’). If you press the ‘-’ key, then the
green lightbulb is on (the signal shows ‘go’). This avoids the
need to use an additional relay on light signals.
Flashing:
In this mode an output’s + and - terminals are activated
alternatingly.
This mode of operation is suited for connecting the flashing
lights at a train crossing or signal. The flashing rate is
programmable; see the section “Programming the settings of
an output” for more information.
General notes: Only one of the output pairs on an LS100/110 is
active at any one time. For example if during pulse or constant
operation the + terminal is active and the - output is activated,
then the + terminal goes inactive, regardless of whether the
pulse duration time is up or not. This applies in the
corresponding manner when the - terminal is activated first and
the + terminal is then activated.
Caution!
When programming the outputs, please note that depending on
pulse duration, or with constant operation, several outputs may
be active at the same time. With all the connected power users,
you must then not exceed the maximum total current load
capacity of 3A for the accessory decoder.

Installing the accessory decoder LS100/LS110
Connecting the LS100/LS110 to a power station and/or
separate power supply line
Before you connect your LS100/LS110 to your NMRA DCC
system or the power supply line, you must turn off your DCC
system and disconnect the power supply (unplug the transformer
from wall outlet). There are two options for connecting your
LS100/LS110: The first option uses the power supplied by your
6Accessory Decoder LS 100/110
DCC system and does not use a separate power supply line to
power the LS100/110. The second option uses an external
power supply to power the LS100/110. Illustrations 1 and 2 show
the connection using the LS110. The LS100 is connected in the
same way, using the same terminals.
Illustration 1: Connecting an LS100/110 to an LV100/101 using a
separate power supply line (LS100 shown)
Illustration1 demonstrates the method of connecting an
LS100/LS110 to the track outputs of a power station. Terminals
'≈≈'are here connected in parallel with terminals J and K to
LV100/101. With this option all the power required to operate
the devices connected to the LS100/110 is supplied by the DCC
power station.
Illustration 2: Connecting an LS100/110 to an LV100/101
(LS100 shown)
Illustration 2 shows how to conect the LS100/110 to an external
power supply. Terminals K and J of the LS100/LS110 are

DIGITAL plus
Illustration 3: Connecting the feedback bus on LS100
8Accessory Decoder LS 100/110
connected to the corresponding terminals on a power station
LV100/LV101. Terminals ‘≈≈‘ are connected to a transformer with
16V AC.
Connecting the LS100 to the feedback bus of LZ100
(LS110 only)
Terminals R and S are connected to the corresponding terminals
on command station LZ100. Please refer to Illustration 3.
All feedback capable devices are connected in parallel to the
feedback bus, as shown. Since each device has its own
address, it does not matter in what order the devices are
connected.
Of course you can use accessory decoder LS100 and feedback
encoder LR100 in any combination. You just need to make sure
that you do not assign any address twice. Information about
shared addresses is found in the sections “Programming
address and settings of the outputs” and “Shared addresses of
LS100/110/120 and LR100” later on in this manual.
Connecting devices to the function outputs
Connecting various devices to the function outputs is shown in
illustration 4. Here are some additional explanations:
Connecting twin-coil turnout drives
The common wire of the two coils (2) is connected with terminal
‘C’. The wire from coil 1 (1) is connected with terminal ‘+’; the
one from coil 2 (3) with terminal ‘-’. Depending on the design of
the turnout drive, activating the ‘+’ terminal will result for instance
in the turnout going to the ‘diverge’ position. If that is not how
you planned it, then switch the connections at terminals
‘+’ and ‘-’.

Connecting light signals with lightbulbs or LEDs
If you wish to connect the outputs to lightbulbs or LEDs, then
program the corresponding outputs on LS100/LS110 to constant
on. You can then connect the lightbulbs or LEDs (using a
resistor) directly to the outputs of LS100/LS110. If you use the
separate AC supply, the digital current will not be used.
Information on programming settings is found in the section
“Programming the settings of an output” later on in this manual.
In Illustration 4 the connection of a signal’s lightbulbs is shown in
the upper left and the connection of LEDs in the lower left.
Important:
When connecting a LED, please remember that terminal ‘C’ is
positive. You must therefore connect the cathodes of the LEDs
in the signal with terminals ‘+’ and ‘-’.
When using LEDs, a current limiting resistor is necessary.
Please determine if this resistor is already installed in your LED
signal.
If that is not the case, then with a supply voltage of 16V AC you
need to use a current limiting resistor of 1.5 kOhm. If the LED is
not bright enough with that, then try lowering the resistor value
(1kOhm). If the LED is too bright, use a larger resistor value. In
the illustration this resistor is indicated with ‘R’.
