Command Link Plus and Helm Master Bus Network
Connection Considerations
NOTICE
If you have an existing engine network on your boat, it should
already be connected to power.
This display connects to the Command Link Plus or Helm
Master engine network on your boat to read data from
compatible devices such as certain engines. The engine
network follows a standard and uses proprietary messages.
The Furukawa connector on the end of the power cable
connects the display to the existing engine network, using the
appropriate length pigtail bus wire. You must route the cable
within 6 m (20 ft.) of the engine network backbone.
For more information on connecting to your engine network, see
the engine documentation.
NMEA 2000
®
Considerations
NOTICE
If you are installing a NMEA 2000 power cable, you must
connect it to the boat ignition switch or through another in-line
switch. NMEA 2000 devices will drain your battery if the NMEA
2000 power cable is connected to the battery directly.
NOTE:
If you are connecting this device to an existing NMEA
2000 network, the NMEA 2000 network should already be
connected to power.
If you are connecting this device to an existing NMEA 2000
network by another manufacturer, you should install a NMEA
2000 Power Isolator (010-11580-00) between the existing
network and this device.
This device can connect to a NMEA 2000 network on your boat
to share data from NMEA 2000 compatible devices such as a
GPS antenna or a VHF radio. If you do not have an existing
NMEA 2000 network, you can create a basic one. For more
.
The port labeled NMEA 2000 is used to connect the device to a
standard NMEA 2000 network.

Garmin Marine Network Considerations
NOTICE
A Garmin Power over Ethernet (PoE) Isolation Coupler (P/N
010-10580-10) must be used when connecting any third-party
device, such as a FLIR
®
camera, to a Garmin Marine Network.
Connecting a PoE device directly to a Garmin Marine Network
chartplotter damages the Garmin chartplotter and may damage
the PoE device. Connecting any third-party device directly to a
Garmin Marine Network chartplotter will cause abnormal
behavior on the Garmin devices, including the devices not
properly turning off or the software becoming inoperable.
This device can connect to additional Garmin Marine Network
devices to share data such as radar, sonar, and detailed
mapping. When connecting Garmin Marine Network devices to
this device, observe these considerations.
• All devices connected to the Garmin Marine Network must be
connected to the same ground.
• A Garmin Marine Network cable must be used for all Garmin
Marine Network connections.
◦ Third-party CAT5 cable and RJ45 connectors must not be
used for Garmin Marine Network connections.
◦ Additional Garmin Marine Network cables and connectors
are available from your Garmin dealer.
• The ETHERNET ports on the device each act as a network
switch. Any compatible device can be connected to any
ETHERNET port to share data with all devices on the boat
connected by a Garmin Marine Network cable.
Differential NMEA
®
0183 Connection Considerations
This device can receive differential NMEA 0183 information from
a compatible device.
• See the installation instructions for the NMEA 0183 device to
identify the wires.
• See the table and wiring diagram when connecting the data
cable to NMEA 0183 devices.
• You must use 28 AWG, shielded, twisted-pair wiring for
extended runs of wire. Solder all connections and seal them
with heat-shrink tubing.
• See
Differential NMEA 0183 Receive Information
for a list of NMEA 0183 sentences that can be received by
this device.
• The internal NMEA 0183 ports and communication protocols
are configured on the connected display. See the NMEA
0183 section of the display owner's manual for more
information.
• Do not connect either NMEA 0183 data wire from this device
to power ground.
• The power cable from this device and the NMEA 0183 device
must be connected to a common power ground.

Tank Level Sensor Connection Considerations
You can connect up to six tank level sensors to the device.
NOTICE
You must connect fuel sensors to inputs 1, 2, 3, or 4. If you
connect a fuel sensor to input 5 or 6, the fuel management
system will not working properly.
