3 How The System Works
Digital switching with the DCM greatly simplifies the electrical
system on your boat. The system provides a cleaner dash by
eliminating switches and placing them on the multi-function
display. Through the display you can easily control your boat
via single button touch. One touch operation modes on MFD
combine different loads for smoother boat operation.
Custom modes and frequently used switches can be
controlled via remote. The system can easily be turned on/
off with the key fob.
3.1 DCM Features
• Combined input and output
channels in one module
• Touch screen compatible
• Small size and footprint
• 16x outputs channels
• 2x “always on” channels
with removable fuses
• Load monitoring
• 6x analog inputs
• 16x switch inputs
• Fuse bypass available on
all outputs
• Wireless remote control
• Battery management
• Voltage monitoring
• NMEA 2000 compatible
• Gateway to CAN devices
3.2 Wireless Key Fob for
DCM Features
• Wirelessly connects with
DCM
• Buttons pre-programmed
in DCM for different
operating modes.
• Multiple identical key
fob’s can be connected.
• Waterproof to a depth of
1 meter
• Optional dash mount
holder
• 750- line of sight range
• 418 MHz, North America
FCC certified
• Single 3V CR2032 Li cell

3.5 Key Fob Pairing Procedure
In case your key fob lost pairing or you received a new key fob
follow this procedure to pair the key fob to the DCM:
1. On the MFD Switching page find Remote Learn button.
2. Press and release the Remote Learn button on the MFD (the
button is located on the MFD Switching page).
3. Press and release any button on the Key fob.
4. Wait 20 seconds for the DCM to exit programming mode.
5. The transmitter and DCM are now paired.
6. Repeat the pairing process for additional transmitters.
7. Up to 40 transmitter addresses can be stored in the DCM.
If a transmitter is lost or stolen, the user may want to clear it
from the DCM’s memory so that it can no longer control the
DCM.
To erase all transmitter addresses, press and hold the Remote
Learn button on the MFD for 15 seconds.
Note that all transmitters must then be re-paired with the
DCM.

a) Garmin MFD is
powered from the
DCM and is powering
off when receiving
prompt to load a new
configuration
a) Place DCM output fuse for MFD into "Bypass Mode" to give continuous power
to MFD during update. It is recommended that a correction to the DCM
configuration is made using SeaStar DCM configuration tool so the particular
output does not power off during future configuration uploads. Call OEM or
SeaStar Service for assistance as needed.
On Garmin MFD Switching

message "Out of Range"
(Example: Out of Range:
Freshwater)
a) The sender/full system
may not be energized
b) DCM module is not
connected to the
NMEA 2000 network
c) The sender is not
properly connected to
DCM module
a) Check the sender's breaker is in the "ON" Position.
b) Find associated DCM module and check device for loose NMEA 2000
connection.
c) Check for sender data at DCM module using a multi-meter.
Garmin screen shows
"Unavailable" message
instead of switches when
on "switching" page
a) Garmin MFD not
connected to NMEA
2000 network
b) SeaStar Instance not set

c) Switching page needs
to
be reset
a) From the Garmin screen homepage press: Settings/ Communication/ NMEA
2000 set-up/ Device List... Does the device list show other devices on the
NMEA network? If not, replace Garmin unit's NMEA drop cable. If problem
persists refer to section 3.2 "NMEA 2000 Network Troubleshooting".
b) From the Garmin screen homepage press: Settings > My Vessel > Switching >
SeaStar > SeaStar Instance to be '0'
c) From the switching page press: Menu > Edit Switches > Restore Default View

Power Management/ Battery Switches & Key Fob
Symptoms Potential Causes Checking Steps and Solutions
Load breaker tripped
or blown fuse
a) Improper voltage
caused load current
to rise causing breaker
to trip or fuse
to blow
b) Harness has short
circuit
c) Load/device has short
circuit
d) If tripped repeatedly
weak/faulty breaker
a) Measure system voltage and restore by charging battery
if required.
b) Disconnect load and turn on breaker or replace fuse to see if the breaker trips
or fuse blows, if it does, there is a short circuit within the breaker's associated
wiring harness.
c) Disconnect the load from DCM, the breaker or the fuse. Measure resistance on
the load to check for short circuit.
Test/ replace with a working load device.
d) Check breaker's load value with a DC current meter (Amp Clamp), If the load is
pulling less than the breaker's capable current rating, replace the breaker.
Wireless key fob doesn't
work
a) Battery inside key fob
requires replacement
b) Key fob needs to be
paired with DCM
c) Faulty Key fob or
receiver
a) Replace battery.
b) See section See 2.7 "Key Fob Pairing Procedure."
c) Test/replace with a working receiver.
Audible noise from speaker
system when load device is
active
a) The load device is
grounded in between
the Stereo head unit and
stereo amplifier
b) The load device is
grounded in between
the battery and the
stereo amplifier
c) A DCM load is creating
PWM (Pulse With
Modulation) noise that
is bleeding into speaker
wires
a) Install a new (separate) 14 AWG ground wire directly from stereo head unit
ground to stereo amplifier ground.
b) Ensure stereo amplifier ground is terminated as close to the battery as possible
with no load grounds in between. Or, apply solution (a).
c) Re-route speaker wires away from DCM load wires.

Troubleshooting Guide

4.2 NMEA 2000
Network Troubleshooting
• Usually troubleshooting requires nothing more than a few
basic tools and knowledge of what a proper NMEA 2000
backbone construction should consist of. Given the tools
and knowledge, troubleshooting could be considered easy,
as all the parts are "Plug and play." Usually technicians use
the process of elimination to find and eliminate problems.
This method is recommended at times however, may not
always work swily if there is more than one piece of faulty
equipment on the network.
• It is recommended to take a NMEA cable and cut the female
end off of the cable, strip back the conductors from the
remaining male cable and terminate them onto a terminal
strip as shown in figure 3-1.
This simple tool will plug into any open position on the
network allowing for easy ability to meter different parts of
the network.
• If there is a problem with a NMEA 2000 network, it is
recommended to start by removing network devices one at
a time. If the network works properly immediately aer
removing a device, t is safe to assume there may be a
problem with the device or the associated network drop
cable. If this method does not resolve the network
problems the next step would be to test the network by
metering.
When Metering a
NMEA 2000 network
The resistance between Net-H (White) and Net-L (Blue) should
be approx. 60 Ohms with the network power turned off.
If this parameter is not met:
• Verify proper construction of NMEA network while
checking for loose connections
• Replace terminating resistors
• If value is still incorrect: Remove all devices from network,
check value again, determine faulty network “T”s , cables or
network power isolators by using process of elimination.
Replace necessary items effecting the network backbone.
With network power on the network voltage (Red & Black
should not be below 11V or Above 15V If this parameter is not
met:
• Charge system batteries
• Check charging system for proper voltage output
• Verify proper construction of NMEA network while
checking for loose connections
• Replace power insertion “T”
• If value is still incorrect: Remove all devices from network,
check value again, determine faulty network “T”s , cables or
network power isolators by using process of elimination.
Replace necessary items effecting the network backbone.
The shield and DC (-) conductor should have continuity
Although it is possible NMEA networks can be effected by
interference it is unlikely.
This rule exists for purposes to shield the network from
interference.
If this parameter is not met:
• Check power insertion point for proper connection, where
the shield is connected to DC (-).
