SWITCH INPUTS (OPTIONAL)
The SCM-LC-N2K Light Commander is congured to
support zone activation switches.
There are 6 zone switch inputs located on connector 3.
The inputs are congured for momentary '+' inputs.
The rst button press will turn the corresponding
lighting zone on to White, the second press will turn the
lights off
Pressing and holding the input will toggle between
dimming and stepping up brightness.
There is one global control input, that will step between
colors on subsequent presses.
Holding the control switch on for more than 1 second
will start color rotation. Color rotation can be stopped
by a subsequent button press.

RECOMMENDED WIRE GAUGES
Scan the QR Code or click here to
view our recommended wire gauge
chart.
INSTALLATION
SCM-LC-N2K INSTALLATION
Central mounting locations under the helm areas or in
the bilges are acceptable.
1. Typical orientation is with Deutsch wire connections
facing down.
2. Use the included four 8 x 3⁄4” SS pan head screws
for mounting.
SCM-LC-N2K POWER REQUIREMENTS
See the Shadow-Caster® wire awg recommendations
for detailed calculations. It is very important to have
sucient gauge wire feeds for RGB lighting. Typical
installations use 8AWG or larger wire.
It is recommended to separate feeds for lighting and
for sensitive stereo power feeds with direct runs to the
battery or a heavy gauge distribution point.
The SCM-LC-N2K Light Commander uses digital current
sensing to detect over current conditions. When this
is detected, the SCM-LC-N2K Light Commander will
disconnect RGBW channels from power and ash the
backlit logo to indicate a fault condition.
The SCM-LC-N2K Light Commander will work in 12V or
24V systems. Please note that 12V or 24 compatible
RGB(W) products should be used depending on the
application.
SCM-LC-N2K LIGHT COMMANDER
OPERATION MANUAL
SELECTING RGB OR RGBW LIGHTING
The SCM-LC-N2K Light Commander is pre-congured
for RGB output.
TO CONFIGURE FOR RGBW
1. Press and hold buttons 1 and 2.
2. Apply main power to the controller - the white
channels should then immediately start ashing.
3. Release the buttons and cycle the power to resume
normal operation.
4. Once detected, release switch 1 & 2 and cycle power
to resume normal operation.
Note: The minimum detection level is 100mA.

Devices
The SCM-LC-N2K Light Commander has four built in
RGBW channels. By default these RGBW channels
correspond to zones 1-4, however, they are independent
and can be assigned to any of the congured zones 1-6
supported by the controller.
The SCM-LC-N2K Light Commander will support 15
amps per each of the 4 RGB(W) channels, for a total of
60 amps in the entire box.

SHADOW-NET®DEVICES
Connect Shadow-NET® enabled devices to the orange
and yellow Shadow-NET® wires coming from the SCM-
LC-N2K Light Commander.
As soon as the SCM-LC-N2K Light Commander receives
power, multiple channels of digital messages start
broadcasting on these wires. These messages allow
Shadow-NET® enabled devices to be connected without
a switch. Initially these commands are for attached
lights to turn off. As soon as a command is given to the
SCM-LC-N2K Light Commander to go to a color, these
attached devices will receive a message to go to the
corresponding color and brightness.
Please note that different products are pre-programmed
to respond to a certain channel. For example,
Underwater Lights respond to Zone 1, Down Lights
respond to Zone 2 and Spreader Lights respond to Zone
3.

BEST PRACTICES FOR MITIGATING
NOISE ISSUES
Noise interface is common in systems with RGB
lighting controls and amplied stereo systems. The
advanced circuitry in the lighting controller does
everything possible to protect from this.
Utilizing installation best practices will further mitigate
these issues.
1. Make sure to supply ample gauge power and sepa-
rate distribution points from stereo power.
2. Run RGB power wires as far as possible from the
speaker feeds for the stereo. Run separate bundles
where possible.

SHADOW-NET®LIGHTS WILL OCCASIONALLY
LOCK UP AND STOP RECEIVING MESSAGES
This indicates that there is a noise issue on the
Shadow-NET® communication lines. Typically this is
caused by insucient gauge wire feeding one or more
Shadow-NET® connected lights.
SHADOW-NET®LIGHTS STAY ON
If the connected Shadow-NET® lights are not turning
off at initial power up then there is a challenge with the
Shadow-NET® connection.
Check the orange and yellow wire connections are not
reversed and are fully connected.
TROUBLESHOOTING
MUSIC SYNC NOT WORKING
Verify that an appropriate 3.5mm stereo jack is being
used and that there is a usable signal.
If a separate output zone is used, verify that the output
is enabled and the output is set to a usable volume.
It is not recommended to use a subwoofer output, as
certain sync modes require the full audio range.
