Nmea 2000 Considerations; Software Update - Garmin GPSMAP 800 Series Installation Instructions Manual

• A Garmin Marine Network cable must be used for all
ETHERNET connections.
◦ Third-party CAT5 cable and RJ45 connectors must not be
used for ETHERNET connections.
◦ Additional Garmin Marine Network cables and connectors
are available from your Garmin dealer.
• If this device has a single ETHERNET port, you may need to
use a Garmin network switch, such as a GMS
a radar or sounder module to more than one ETHERNET
device.
• If this device has both a RADAR port and an ETHERNET
port, you can connect an ETHERNET device to either port.
• Some sounder modules, such as the GCV
than one ETHERNET port, and can connect to multiple
ETHERNET devices without an additional network switch.
Connecting the Device to a Remote GPS Antenna
This device has an internal GPS receiver, but some installations,
such as a flush-mount installation, may not allow a view of the
sky needed to calculate your GPS position. In this situation, you
can install a Garmin external GPS antenna and connect it to the
device to provide GPS information.
Devices that can receive information from a Garmin external
GPS antenna have a port labeled EXT GPS.
1
Follow the instruction provided with your Garmin external
GPS antenna to install it on your boat correctly.
2
Route the antenna cable to the back of your device, away
from sources of electrical interference.
3 Connect the antenna cable to the EXT GPS port on your
device.

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.
NMEA 2000 compatible models can connect to a NMEA 2000
network on your boat to share data from NMEA 2000 compatible
devices such as a VHF radio. The necessary NMEA 2000
cables and connectors are sold separately.
If you are unfamiliar with NMEA 2000, you should read the
"NMEA 2000 Network Fundamentals" chapter of the Technical
Reference for NMEA 2000 Products. To download this
document, select Manuals on the product page for your device
at www.garmin.com.
The port labeled NMEA 2000 on the back of the device is used
to connect it to a standard NMEA 2000 network.
