INTRODUCTION
The LED Scene Controller II (LSC II) is a powerful but simple-to-
use LED animation controller. 100 behaviors have been
preprogrammed so it’s simply a matter of selecting an output
port and then assigning a number representing that behavior.
There are 16 ports and depending on what type of LED you are
using and at what brightness setting you can connect as many as
64 LEDs. Use our 1-to-4 connector to connect up to four LEDs
per port.
The LSC II has a 1Amp capacity.
Each pin can operate separately, or multiple pins can be
“coordinated” to create other effects. For example, the alternate
flashing mode allows any two adjacent pins to, you guessed it,
alternate flash. If you set all 16 pins to this mode, you have a
marquee lighting effect. This one controller can run the police
lights, a crossing gate, multiple random on off ports, a rotating
beacon, fade street lights on and off and show a TV simulation in
a building – all at the same time!
Additionally, if you have a DCC Command System for running
your trains, you can connect the LSC II and control (turn on and
off and configure) any combination of those effects from your
hand controller.
A common challenge with using LEDs is deciding what voltage
and resistor value to use so as not to burn them out. To solve
this the LSC II allows you to control the effective output voltage

6
MODEL TRAIN TECHNOLOGY ™
by setting the maximum brightness. This allows you to mix and
match 3.3v and 12v LED on the same LSC II.
We’ve enclosed the LSC II inside a sleek case and designed the
base of the unit with a slot that allows you to slide the LSC II onto
a matching mounting bracket.
Here are the special effect categories for reference.
• Adjust each LED for individual “brightness”
• Flickering
• Blinking with individual pin on/off speeds
• Rotating Beacon (simulation)
• MARS simulation
• Fade all, one or groups of pins with up to 18 hour timer.
• Random on/off with adjustable pace (all pins or one pin)
• Step, Chase, Race – each LED on/off in sequence
• Alternate 2-pin Flashing
• TV Simulation (use 2,3 or 4 LEDs)
• Arc Welding
• Lighting
** Some speed settings apply to all LEDs whereas blinking and brightness settings
apply individually to each LED (they can be different). If you have multiple boards with
the same DCC address but you program them separately, they will perform based on
the board specific configuration.
You can also configure and control the LSC II from your NMRA®
DCC system. That also means you can use jmri (www.jmri.org) or
similar control software. Our favorite is Railroad Automation
(RRAuto.com) Please see the LSC II DCC Manual.

OVERVIEW
1. POWERING the LSC II (12-25V DC or AC, 1A)
To provide maximum convenience and adaptability, the LSC II has two
types of sockets into which you can connect power.
YOU ONLY NEED ONE POWER SUPPLY.
There is a slide switch on the front of the LSC II that allows you to select
which input plug you want to use. Even if you plug in two power supplies
ONLY one will be active at a time.
Here are the options:
2. The Woodland Scenic power adapter can plug directly into the LSC II
via the WHITE JST socket.

8
MODEL TRAIN TECHNOLOGY ™
3. An adapter (12-18vDC 1A recommended) with a 1.3mm Barrel plug.
(available at this link or via our store)
4. 1.3mm barrel plug with terminal screws to connect your own wires to
the LSC II. (Included)
5. JST “pigtail” and connect wires that way. Black/Red orientation for the
power supply does not matter.
Note: While our LSCI MICRO board allows you to power the board via
your DCC system,The LSC II with Keypad requires an external power
supply to operate properly. If you connect DCC to the LSC II it will only
read the digital signal, which is only a few milliamps, and will not draw
current to power the LEDs.

OPERATIONS
Use the POWER SELECTOR switch to select your power source. To turn on
the LSC II, slide the right-hand slide POWER ON/OFF switch to the RIGHT.
The blue LED on the top of the case will turn on.
The 4-number LEDs may flash or have on odd segment lit but after 2
seconds you will see “
1234
” on the display and then the numbers will
disappear. This indicates that all is working. At that point the LEDs that
you plugged in will all turn on depending on what FX setting you set. The
default mode for each port is ON and the brightness setting is 20%
The LSC II has two modes. It is either in Animation Mode or Configuration
Mode. If you see any red numbers on the top of the LSC II, the LSC II is in
Configuration Mode. If they are off and the blue light is on, the LSC II is in
Animation Mode.
If the blue light is off, the LSC II power is Off.

10
MODEL TRAIN TECHNOLOGY ™
To switch between Animation mode and Configuration mode, push and
hold button the LEFT TOP Keypad On/Off button for about 1 second and
release. Pushing this button toggles back and forth between these two
modes. The LSC II will not react to a very quick push. If your push is too
long the LSC II will switch back and forth. After a few tries you will get the
hang of it.
There are two pairs of “number” LEDs on the top of the LSC II. On the left
is the number of the selected Port. When you switch to configuration
mode this will always start at “1”.
To change the port number, push the Up or Down black buttons
on the left side top of the LSC II.
On the right side are the two digits that represent the configured
special effects behavior. There are 99 built-in special effect
options, plus “0” (zero) which is OFF for that port. See the chart.
To configure a Port to behave with a specific special effect, select
the port number on the left and then select the behavior number
on the right side.
Press the
SAVE
button once to save this to the LSC II. The digits
will blink indicating a successful save. The setting is saved even
when power is turned off or disconnected.
You can change the setting as many times as you want.
Remember to press Save.
To see the behavior, switch back to Animation mode.
ADJUSTING THE LED BRIGHTNESS:
To adjust the brightness of any Port, switch the LSC II into
Configuration mode. Press the Right-side button on the top
once. You will see decimal points on each displayed digit of the

11
MODEL TRAIN TECHNOLOGY ™
LSC II. The number on the right now indicates the brightness
level 0-99% of the port that is selected on the left. Push the
black Up and Down buttons on the right side of the LSC II to
adjust the brightness up or down.
3.3V and 12V settings
The LSC II is configured so that a 100% brightness setting is ~14VDC. This
is a few volts higher than 12V which is maximum for the Woodland Scenic
Roomette® products as well as other 12V LEDs. The default brightness of
all the ports is set at 10%. This is the MAXIMUM value for 3.3V LEDs with
a 25V power source. In this way if you plug in only 3.3V LEDs when you
start up you won’t have any problems. And then you can adjust them as
you need.
It is possible to burn out 3.3V LEDs very quickly by applying
excess voltage above the 10% setting. We opted to give you
this flexibility so that you can mix and match 3V and 12V LEDs on
the same LSC II. Please use this wisely.
Here are the approximate voltages for different power sources:
Power Adapter Output Maximum Port voltage output
25vdc (Woodland Scenic) 14.0v
18v 13.9v
12v (for 3.3V LED only) 8.6v
Press the
SAVE
button to save the new setting. If you don't press Save
and you change ports or switch modes, the LSC II will revert to the
previously saved setting.
To switch out of adjusting the brightness, press the Right-side button once
more. The decimal points will disappear, and the number will change to
the value representing the special effect setting. Pressing the button again
will toggle back and forth between setting the Brightness and setting the
special effects Behavior for the port number that is shown on the left.

12

If you forget what the button does and you have lost this piece of
literature, flip the LSC II upside down to see the reference key.
The arrow keys have a “fast” mode. If you hold the key down for 2
seconds, the rate of change roughly doubles.

The LSC II has 16 Ports, labeled counterclockwise as viewed from the top
of the LSC II. You can use the ports in any order.

CONFIGUREING THE LSC II for Special Effects
We suggest you start with some basic setting so you can quickly become
familiar with how the LSC II works. Let’s start with what we call “singles”.
Most of the special effects are grouped into TENs with the first digit
representing the basic FX. In the chart below, 2 is the number for Flicker.
If you set a port to 2 it will Flicker at the default setting. As you will see in
the 100 Chart, all the “2” are grouped. So any effect whether 2 or 21 or 25
will Flicker. Likewise, with 3. All effects that begin with 3 will blink.
Try some of the settings below to get the effect (pun intended).
FEATURE: When you have more than one Port set to a common first
value, say all set to 22, when you change ANY Port that has a leading 2, all
the ports will change to that same new number. If you change Port 5 from
22 to 24, all pins that were 22 before will now change to 24. This is
necessary to keep the integrity of the timing of the flicker behavior. There
are some exceptions:
FX that begin with 1 will not change.
FX that begin with 3 (Blink) will not change.
FX that begin with 5 (Fade) will not change
FX that begin with 9 will not change.

OTHER NOTES:
• Some FX work with several ports in unison. Step, Chase, Race and TV
sim work this way by design. But you can also mix effects on
different ports. For example, you might use an Arc Welding FX with
a flicker effect on a red LED to simulate the hot metal.
On one of our displays we have a HO police car that we kit bashed
from Woodland Scenic. We connect the headlights, rear lights and
the top Red beacon to three different LSC II ports and three different
effects.
Step, Chase and Race require a group of adjacent pins to make
sense. The effect will turn each light on in sequence with a small
timing gap between them.
• The MARS effect uses the Beacon Timing. Therefore, to set the
speed of the MARS effect, set the PORT to the Beacon setting that
corresponds to the desired speed. Save it. Then change the Port FX
to Mars.
• Mimic F11 and Mimic F12 are specific to use with a DCC System.
Hitting F11 or F12 on the DCC hand controller will cause any Port set
to Mimic to turn on and off with Port 1 if F11 and Port 12 with F12.
• Fade – Fade timing is by default in 10 second increments. This can
be increased or decrease via CV #127. The range is 1-255. The
duration of the ON time and OFF time are set via the keypad or CV’s.
(see the chart). The range is 1 to 255. Thus with 255 set to a port ON
and the seconds increment set to 255 you can have a timer that is
65,025 second or 18 hours long! That is extreme but this wide range
allows you to set your layout animation to turn the lights on and off
to a 24-hour cycle. For example, ON for 12 hours and then OFF for
12 hours, or On for 18 hours and OFF for 6. The LSC II does not
have a real-time-clock (RTC) so it’s only counting seconds from when

17
MODEL TRAIN TECHNOLOGY ™
the device is powered and animation is activated. It doesn’t know
what time of day it is.
• Fade = 50. If you set a port to Fade using the preprogrammed value
of 50, it will disable the Fade timer for that pin but set the pin to fade
on command. This allows you to have a Fade effect on ports that
you control only via DCC. To return the port to an active timer,
select either “5” or any other 50’s value (like 51) other than “50”.
Think of the zero of the 50 as “off”.
• Welding 1,2 and 3 use different time gaps between activity. 1 is the
shortest and 3 is the longest. Combine these on different Ports so
that one activity FX is the white-hot arcing and the longer period
could be a RED led meant to show the red-Hot arcing.
• Lighting – setting them Mode to 16 follows the value in CV 125 which
is a 1-minute delay by default. Lighting 17 divides this by ½and
Lighting18 doubles the value.
• The Step FX turns on and off LEDs in sequence starting at Port 1 (if it
is set to a 7 series) through to 16. It will skip Ports that are not set to
a 7 series 71-79)
o The Race sequence repeats by starting at 1
o The Chase sequence repeats by going backward from 16, then
forward at 1, so back and forth.
o Each LSC II can either Race or Chase but not both
simultaneously.
• DCC Signal Scan is the amount of time that the LSC II waits after
power on to switch into animation mode if it does not detect a DCC
Signal. You can select ANY Port since it affects the entire device,
select the value for the delay option and press SAVE. The previous
FX behavior for that Port will NOT change.
To see the effect, you must switch OFF the LSC II. After it’s start up
cycle you will be able to detect a change in time that it takes to start

18
MODEL TRAIN TECHNOLOGY ™
the animations – assuming you are not connected to DCC. If you are
connected to DCC, you must press F5 (Animation ON/OFF) to
activate the device animation.
• TV Simulation works with a White and Blue LED on separate Ports or
in Color with a 3 separate Ports connected to an RGB (Red-Green-
Blue) LED. The LED type is common Anode. (You can buy the proper
RGB LED chip from our store.) The different settings are meant to
simulate different types of TV activity. It’s not perfect but it is
effective, nonetheless. You can mix the FX on each color line if you
want. This effect is a Random-on-Random effect so it may be very
difficult to track the differences.
• Relay – The LSC II will drive the digital inputs of both 5VDC and
12VDC Relays which use a 5V digital signal. When you select 99 for
relay, the LSC II will automatically set the power setting to 27%
assume a 25vdc input. Adjust accordingly for different input voltages
to get 5vdc output.
RESET
There are a few reasons that you may want to reset the LSC II back the
factory defaults. One is that you forgot the DCC Address. Or, you just
want to get back to the default settings.
TO RESET THE LSC II, turn on keypad mode. It doesn’t matter what the
display is showing, just that the display is on.
Then, PRESS AND HOLD the two black UP ARROW buttons. After about 5
seconds, the display will read all ZERO. Release the buttons. Once the
reset is complete the display will blink as few times and then return the
display showing PORT #1 set to “1”.

WRITING CVs WITH THE KEYPAD
If you don’t have a DCC system, it is still possible to change CV values in
the range of 112 to 191 with the keypad. Check the MASTER CV LIST for
the specific value you may want to change.
After using the Keypad to change CV values you must turn OFF the LSC II
to allow it to reload the new values and keep all the internals straight.
To enter CV write mode, Press and Hold the two black DOWN ARROW
keys (one on the left and one on the right). The display will show a “C”
and then the number 112, which is the first CV value that can be
configured. Use the up and down keys on the RIGHT side to select the CV
you want to change. Then, using the LEFT side Up/Down keys you switch
the display to show a dash “-“followed by the current CV value.
Using the right side Up/Down keys select the new value for the CV.
Use the left side arrow keys to switch between CV Address and CV value.
Press
SAVE
to write the new CV value.
To exit the CV mode, press the Keypad On/Off button.
Remember to turn power OFF and back on to restart the LSC II with the
new values.
Note: you cannot change the DCC address of the board using this method.
Use your DCC System to change the board address – which make sense. If
you are using the LSC II without DCC, there is no need to change the
board address.
Why the strange values of 112-191? The LSC II was designed to be used
with NMRA (National Model Railroad Association) compatible DCC
systems. To assure compatibility among different manufactures a range of
memory location was reserved for their use. There are a couple of blocks
of these numbers that start at 1 and go to over 1000. 112 is the start of
