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:

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’.
