DESCRIPTION
The SC910 is designed to be a compact DMX controller
and remote station control device. When used as a
standalone controller, the SC910 is capable of
independently controlling 512 channels of DMX and
has the ability to record and recall 18 scenes. The scene
control is broken down to 10 real time fader controls and
8 push buttons with user defined fade times. This device
features the ability to set a fixed output value or park
DMX channels. The SC910 is able to connect to a DMX
data chain with another DMX controller. The SC910 can
operate with other types of Lightronics smart remotes
and simple remote switches to recall 16 of the 18
available scenes from additional locations. Scenes 17 &
18 are only available from fader 9 & 10 on the SC910.
These remote units will connect to the SC910 via low
voltage wiring.
The SC910 is the ideal device for architectural control
of DMX512 lighting systems. It can be used as a backup
to a DMX console, great for controlling LED lighting
for special events or anywhere that requires quick, easy
control of a full universe of DMX.
SC910D INSTALLATION
The SC910D is portable and is intended to be used on a
desktop or other suitable horizontal surface.
SC910D POWER & DMX CONNECTIONS
A 120 Volt AC power outlet is needed for the power
supply. The SC910D includes a 12 Volt/ 3 Amp, DC
power supply that has a 2.1mm barrel connector with
POSITIVE center pin.
TURN OFF ALL CONSOLES, DIMMER PACKS, AND
POWER SOURCES BEFORE MAKING EXTERNAL
CONNECTIONS TO THE SC910D.
DMX connections are made using 5 pin XLR
connectors located on the rear edge of the SC910D

SC910D SIMPLE REMOTE CONNECTIONS
The DB9 connector pins 1 - 5 are used for connecting
simple switch remotes.
An example with two switch remotes is shown below.
The example uses a Lightronics APP01 switch station
and a typical pushbutton momentary switch. If the
SC910D simple switch functions are set to factory
default operation, then the switches will operate as
follows:
1. Scene #1 will be turned on when the toggle
switch is pushed up.
2. Scene #1 will be turned off when the toggle
switch is pushed down.
3. Scene #2 will be turned on or off each time the
pushbutton momentary switch is pressed.
SC910D SMART REMOTE CONNECTIONS
The SC910D can operate with two types of smart remote
stations. This consists of Lightronics pushbutton
stations (AK, AC and AI series) and the AF fader
stations. Communication with these stations is over a 4
wire daisy chain bus which consists of a dual twisted

pair data cable(s). One pair carries the data, while the
other pair supplies power to the remote stations.
Multiple smart remotes of different types can be
connected to this bus.
An example using an AC1109 and an AF2104 smart
remote wall station is shown below.
SC910W INSTALLATION
The SC910W (or wall mount) is designed to fit in a
standard 5 gang “new work” style junction box. Be
certain to keep line voltage connections away from the
SC910W and the junction box housing the unit. A trim
plate is included with the SC910W.
SC910W POWER & DMX CONNECTIONS
The SC910W uses an external 12 Volt/3 Amp, DC
power supply, which is included. Connecting power to
a wall mount will require connecting the positive wire
to the +12V terminal and the negative wire to the -12V
terminal on the two pin J1 connector located on the back
of the device.
When making power and DMX connections to the
device, make all low voltage connections and check DC
output prior to mating the connector with the male pins
located on the rear of the SC910W. Do not make any of
the connections with voltage present or while any
devices on the DMX data chain are transmitting.
DMX is installed in a similar way on the removable 6
pin connector J2. The figure below shows the proper
wiring of the power and DMX connections.
SC910W SIMPLE REMOTE CONNECTIONS
The upper five terminals of J3 are used to connect
simple switch remote signals. They are marked asCOM,
SW1, SW2, SW3 and COM. The COM terminals are
connected to each other on the printed circuit board.
An example with two switch remotes is shown below.
The example uses a Lightronics APP01 switch station
and a typical pushbutton momentary switch. If the
SC910W simple switch functions are set to factory
default operation, then the switches will operate as
follows:
1. Scene #1 will be turned on when the toggle
switch is pushed up.
2. Scene #1 will be turned off when the toggle
switch is pushed down.
3. Scene #2 will be turned on or off each time the
pushbutton momentary switch is pressed.

SC910W SMART REMOTE CONNECTIONS
The SC910W can operate with two types of smart
remote stations. This consists of Lightronics pushbutton
stations (AK, AC and AI series) and the AF fader
stations. Communication with these stations is over a 4
wire daisy chain bus which consists of a dual twisted
pair data cable(s). One pair carries the data, while the
other pair supplies power to the remote stations.
Multiple smart remotes of different types can be
connected to this bus.
Connections for the smart remotes are on the bottom 4
terminals of J3 marked COM, REM-, REM+, and +12V.
An example using the AC1109 and AF2104 smart
remote wall stations is shown below.
DMX CONTROLLER OPERATION
For the best results, it is advised - when installed on a
large DMX data network or any network containing
devices with “Master/Slave” functions such as select
Lightronics FXLD or FXLE fixtures - an optically
isolated splitter be installed on the output side of the
SC910 in the DMX data chain.
Once the SC910’s DMX and remotes are connected, the
unit is ready to be powered on. Upon start up, the SC910
will flash the software version number then go to an
OFF state, illuminating the “OFF” LED.
DMX INDICATOR LED
The green LED indicator conveys the following
information about the DMX input and DMX output
signals.
OFF
DMX is NOT being received
DMX is NOT being transmitted
BLINKING
DMX is NOT being received
DMX is being transmitted
ON
DMX is being received
DMX is being transmitted
REC SWITCH AND REC LED
The RECORD switch is a pushbutton recessed below
the face plate to prevent accidental operation of the
record function. It is located to the right and below the
red RECORD LED. You will need a small tool (such as
a piece of solid wire or paperclip) to push the button
when recording.
CHN MOD BUTTON AND LED
The SC910’s CHN MOD button is used to toggle
between scene and channel mode. After startup, the
device will default to scene mode. When in this mode,
the unit acts as a replay device, each of the buttons and
faders will recall any previously recorded scenes.
When the CHN MOD button is pressed, the amber LED
beside the button will illuminate, signifying that the
SC910 is now in channel mode. In this mode, the device
can be used like a DMX console or scene setter,
allowing the user to set/change/modify/store scenes on
any combination of levels using up to 512 DMX
channels. Press CHN MOD and follow all steps in the
next two sections of this manual to set outputs.
SETTING CHANNEL LEVELS
The ten faders on the SC910 user interface are used to
set levels for a block of ten DMX channels at a time.
Once set, those levels remain live until they are changed
or a clear command is given. While in CHN mode, any
changes to a DMX controller that inputs to the SC910
will not be received. Any changes to a DMX channel
from the SC910 will follow a Last Takes Precedence
priority.
The SC910 uses a unique addressing system to access
blocks of faders. DMX channels 1 - 10 are the defaults
for fader operation when the unit is powered up and
switched to channel mode. To access a block of ten
channels other than the default (1-10) the SC910 uses
additive addressing. Utilizing the eight buttons on the

Page 6 of 13

Lightronics Inc. 509 Central Drive Virginia Beach, VA 23454 757 486 3588
left side of the unit, labeled ‘+10’, ‘+20’, ‘+30’, ‘+50’
etc. Addressing is achieved by pushing a combination
adding up to the desired DMX start address. Any block
of ten channels out of the 512 available channels are
accessible using this procedure buttons.
For example, to access channel 256 when starting with
the default ‘+0’, press ‘+50' and ‘+200'. 256 will then be
on fader 6. To access channel 250, again starting from
the default, press '+200', '+30' and '+10'. Channel 250
will now be the 10th fader (channel 241 will be the first
fader).
A chart outlining the buttons used to access any of the
512 available DMX channels is available on page 10.
Press and hold the OFF CLR button for 3 seconds to set
all SC910 DMX values to zero, until a fader is moved.
SETTING FIXED DMX CHANNELS (PARKING)
DMX channels can be assigned a fixed output level or
be “parked” at any value above 1%. When a channel is
assigned a fixed DMX output value the output will
remain at that value in both scene and channel mode and
cannot be overridden by scene recalls or by independent
DMX control. To set a DMX channel to a FIXED
output:
1. Set the fader(s) associated with the DMX channel to
the level(s) desired.
2. Press the REC button for 3-5 seconds until the REC
and LEDs for 1-8 begin to flash.
3. Press the CHAN MOD button (begins to flash) and
press 88.
4. Press CHAN MOD. The CHAN MOD and REC
LEDs are now on solid.
5. Press 3327 (the LEDs will flash acknowledging your
entry).
6. Press REC button to record the change.
To erase a fixed channel output follow the steps above
setting the level for each of the DMX channels to regain
normal operation to a value of 0% on the fader.
It is important to note which channels have been parked
so they can be changed later if needed.
OPERATION WITH ANOTHER DMX CONTROLLER
The SC910 can be connected to a DMX chain with
another DMX controller/console. If a DMX controller
is already transmitting a signal to the input of the SC910,
once the SC910 is placed in CHAN MOD, no changes
from the DMX input will bepassed. The SC910 defaults
to transmit ‘last look’ (last known values for all
channels) for seamless integration with a DMX control
console. With no power to the SC910, the DMX signal
will be passed directly to the DMX output connection.
Push the CHAN MOD button once to enable local
operation. The unit will begin sending the DMX values
set by using the faders. Values set in channel mode
previous to the SC910 receiving a DMX signal will not
be retained.
OPERATION WITH REMOTE STATIONS
While in CHAN MOD mode, the SC910 will accept
responses from simple and smart remote operation,
however the actions WILL NOT occur until the SC910
is taken out of CHAN MOD.
SCENE OPERATION
RECORDING SCENES
The SC910 can store scenes created using the SC910’s
DMX control feature or snapshot scenes from a
connected DMX Device. To record scenes from the
SC910 internally, use the steps outlined in the
SETTING CHANNEL LEVELS section of this manual
to set up the desired look and then follow the steps in
this section.
When the SC910 receives a valid DMX512 signal, the
GREEN DMX LED will be solid as outlined in the
DMX CONTROLLER OPERATION section of this
manual. Once the LED is on solid, the SC910 is ready
to start recording scene snapshots. To record or re-
record a scene:
Set any DMX channels to the value you desire to
capture using the SC910 or control console connected to
the SC910. (Verify the SC910 is in CHAN MOD to
create scenes within the SC910.)

Lightronics Inc. 509 Central Drive Virginia Beach, VA 23454 757 486 3588
Hold down REC on the SC910 until the REC LED
indicator begins to flash (about 3 sec.).
1. Push the button or move the fader in the location
corresponding to the scene you want recorded. The
REC and scene LEDs may flash, indicating that
recording was completed successfully.
2. Repeat steps 1 through 3 to record any subsequent
scenes.
To clear a scene, turn the OFF/CLR button on, then hold
record, (all 8 scene LEDs will being flashing) then select
the scene.
RECALLING SCENES
When recalling scenes to the SC910, it is important to
keep in mind that scenes recorded on the buttons will be
played back at the levels recorded with the set fade rate,
while scenes recorded to faders can be manually faded
in and out or played back at a fraction of the original
percentages captured. Scenes will pile onto the internal
and incoming DMX signal. The SC910 defaults to a
Highest Takes Precedence (HTP) merge between
scenes.
Set CHN MOD to off,(LED not illuminated) then press,
push or pull up any previously recorded button or fader.
When multiple scenes are recalled the SC910 will
combine the recorded values with the highest value
taking precedence. For example, when channels 11-20
are recorded to button 1 at 80% and button 2 at 90%, if
both buttons are pushed the SC910 will transmit a value
of 90% on channels 11-20. A combination of buttons
and faders can be used to recall several scenes at a time.
This technique can be used as a means of controlling
fixtures with several attributes or parameters. For
example, if a group of LED fixtures controlled by a
SC910 have a 4 channel profile that contains a discrete
channel for each; MASTER, RED, GREEN and BLUE,
by assigning the master channels at full for each fixture
to one push button, a control group can be created. Each
fixture’s respective RED, GREEN, and BLUE channel
can then be assigned to a common fader, allowing for
seamless control of the colors without crossfading the
master intensities.
OFF CLR FUNCTION
The OFF CLR button turns off pushbutton scenes 1-8
and any pushbutton remote stations assigned to Scenes
1-16. The OFF CLR button will have no effect on any
remote fader stations. If any scenes are selected from a
remote station, the OFF CLR LED will be off. Scenes
that are controlled by faders must be turned off by
bringing scene faders to 0.
SYSTEM CONFIGURATION
The behavior of the SC910 is controlled by a set of
function codes and their associated values. A full list of
these codes and a brief description is listed below.
Specific instructions for each function will be provided
later in this manual. A diagram at the back of this
manual gives a quick guide to programming the unit.

ACCESSING AND SETTING FUNCTIONS
1. Hold down REC for more than 3 seconds. The REC
light will begin blinking.
2. Push CHN MOD. The CHN MOD and REC lights
will blink alternately.
3. Enter a 2 digit function code using the scene buttons
(1 - 8). The scene lights will flash a repeating pattern of
the code entered. The unit will return to its normal
operating mode after about 20 seconds if no code is
entered.
4. Push CHN MOD. The CHN MOD and REC lights
will be ON. The scene lights (in some cases including
the OFF(0) and BNK(9) lights) will show the current
function setting or value.
Your action now depends on which function was
entered. Refer to the instructions for that function. You
can enter new values and push REC to save them or push
CHN MOD to exit without changing the values. At this
point, the unit will return to its normal operation mode
after 60 seconds if no function settings are entered.
SETTING FADE TIMES (Function Codes 11 - 32)
The fade time is the minutes or seconds to move
between scenes or for scenes to go ON or OFF. The
fade time for each scene can be individually set. The
SC910 pushbuttons are Scenes 1-8, Scenes 9-16
correlate to SC910 faders 1-8, however the fade time
settings is only applicable to the use of either push
button smart remotes or simple remotes assigned to
Scene 9-16. The allowable range is from0 seconds to 99
minutes.
Fade time is entered as 4 digits and can be either minutes
or seconds. Numbers entered from 0000 - 0099 will be
recorded as seconds. Numbers 0100 and larger will be
recorded as even minutes and the last two digits will not
be used. In other words; seconds will be ignored.
After accessing a function (11 - 32) as described in
ACCESSING AND SETTING FUNCTIONS:
1. The scene lights + OFF(0) and BNK(9) lights will be
flashing a repeating pattern of the current fade time
setting.
2. Use the scene buttons to enter a new fade time (4
digits). Use OFF for 0 and BNK for 9 if needed.
3. Push REC to save the new function setting.
Function Code 32 is a master fade time function which
will set ALL fade times to the value entered. You can
use this for a base setting for fade times and then set
individual scenes to other times as needed.
SIMPLE REMOTE SWITCH BEHAVIOR
The SC910 is very versatile in how it can respond to the
simple remote switch inputs. Each switch input can be
set to operate according to its own settings.
Most settings pertain to momentary switch closures.
The MAINTAIN setting allows the use of a regular
ON/OFF switch. When used this way, the applicable
scene(s) will be ON while the switch is closed and OFF
when the switch is open.
Other scenes can still be activated and the OFF button
on the SC910 will turn the MAINTAIN scene off. The
switch must be cycled off then on to reactivate the
MAINTAIN scene.
SETTING SIMPLE SWITCH INPUT OPTIONS
(Function Codes 33 - 35)
After accessing a function (33 - 35) as described in
ACCESSING AND SETTING FUNCTIONS:
1. The scene lights including OFF(0) and BNK(9) will
flash a repeating pattern of the current setting.
2. Use the scene buttons to enter a value (4 digits).
Use OFF for 0 and BNK for 9 if needed.
3. Push REC to save the new function value.
The function values and description are as follows:
SCENE ON/OFF CONTROL

active at any given time.
Other scenes (not part of that group) can be on at the
same time as scenes in a group.
Unless you are going to set one or two simple groups of
non-overlapping scenes you may want to experiment
with the settings to get different effects.
SETTING SCENES TO BE PART OF A MUTUALLY
EXCLUSIVE GROUP (Function Codes 41 - 44)
After accessing a function (41 - 44) as described in
ACCESSING AND SETTING FUNCTIONS:
1. The scene lights will show which scenes are part of
the group.
2. Use the scene buttons to toggle scenes on/off for
the group.
3. Push REC to save the new group set.
Scenes within the Mutually Exclusive Group will
operate with a Last Takes Precedence merge but will
still pile on to the input DMX signal.
SETTING FADER STATION STARTING SCENE
(Function Codes 51-54)
Several pushbutton and fader stations can be used to
access different scene blocks on the SC910. This allows
for the use of two different smart stations set to different
Architectural Unit ID Numbers, also referred to here as
“Station ID”, to control two different blocks of scenes.
The scene blocks are created using the Station ID #
functions and selecting the first scene in a block. The
pushbuttons scenes set on the SC910 are scenes 1-8,
whereas the scenes assigned to the SC910 faders are
scenes 9-18. Scenes 1-16 are assignable to remotes
leaving scene 17 & 18 specifically for SC910 control.
After accessing a Fader ID function # (51 - 54), using
the steps outlined in ACCESSING AND SETTING
FUNCTIONS, the indicators for the current starting
scene will flash back as a four digit code. The following
steps will allow you to change the current setting.
1. Input the number of the scene you wish to have
assigned to fader 1 on the AF as a four digit number.
2. Press the record button to save your selection.
For example, referring back to the diagram on page 4 of
this manual, you can have an AC1109 and an AF2104
