Station Connection Considerations; Garmin Marine Network Considerations - Garmin GPSMAP 8400 series Installation Instructions Manual

addition, connecting the power cable without the appropriate
fuse in place voids the product warranty.
1
Route the power cable to the power source and to the device.
2
Connect the red wire to the positive (+) battery terminal, and
connect the black wire to the negative (-) battery terminal.
3
Install the locking ring and o-ring on the end of the power
cable.
4
Connect the power cable to the device by turning the locking
ring clockwise.
Additional Grounding Consideration
This device should not need additional chassis grounding in
most installation situations. If you experience interference, you
can use the grounding screw on the housing to connect the
device to the water ground of the boat to help avoid the
interference.
Power Cable Extensions
If necessary, the power cable can be extended using the
appropriate wire gauge for the length of the extension.

Station Connection Considerations

This device can be set up in conjunction with other compatible
Garmin devices to work together as a station. When planning
stations on your boat, observe these considerations.
• Devices earlier than the GPSMAP 8000 series and GPSMAP
8500 series cannot be used in a station.
• Although it is not necessary, it is recommended that you
install all of the devices you plan to use in one station near
each other.
• No special connections are necessary to create a station, as
long as all of the devices are connected to the Garmin Marine
Network

(Garmin Marine Network Considerations,

page 3).
• Stations are created and modified using the device software.
See the owner's manual provided with the device for more
information.
Garmin Marine Network Considerations
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 NETWORK ports on the device each act as a network
switch. Any compatible device can be connected to any
NETWORK port to share data with all devices on the boat
connected by a Garmin Marine Network cable.
NMEA 2000 Considerations
®
If you have an existing NMEA 2000 network on your boat, it
should already be connected to power. Do not connect the
NMEA 2000 power cable to an existing NMEA 2000 network,
because only one power source should be connected to a
NMEA 2000 network.
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.
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. The included NMEA 2000 cables
and connectors allow you to connect the device to your existing
NMEA 2000 network. If you do not have an existing NMEA 2000
network you can create a basic one using cables from Garmin.
If you are unfamiliar with NMEA 2000, you should read the
"NMEA 2000 Network Fundamentals" chapter of the Technical
Reference for NMEA 2000 Products. You can find this document
using the "Manuals" link on the product page for your device at
www.garmin.com.
The port labeled NMEA 2000 is used to connect the device to a
standard NMEA 2000 network.
