Radar Operation; Front-Of-Boat Offset - Garmin GMR 430 XHD3 Series Installation Instructions Manual

Garmin Network Considerations
This radar connects to compatible Garmin devices to share radar data. When connecting this radar to a Garmin
network device, observe these considerations.
There are two sizes of Garmin network cable connectors that may be used on various devices in your system.
• The smaller network connectors are present on many newer Garmin devices.
◦ These connectors are similar in size and shape to a NMEA 2000
are different and do not allow you to connect to a NMEA 2000 network.
◦ You can connect devices with the smaller network connectors to one another using a Garmin network
cable with smaller connectors.
◦ This radar has a smaller Garmin network connector and is packaged with a cable that has smaller
connectors on both ends.
• The larger network connectors are present on most older Garmin devices.
◦ These connectors look similar to traditional RJ45 network connectors.
◦ You can connect devices with the larger network connectors to one another using a Garmin network cable
with larger connectors.
◦ To connect this radar to an older device with a larger connector, you can use the included adapter.
This radar provides data to a connected chartplotter. When the chartplotter is connected to other Garmin
network devices, it shares the radar data over the network with all of the compatible connected devices.
Additional Garmin network cables, cable extensions, and adapters are available from your Garmin dealer, or go
to buy.garmin.com.

Radar Operation

All functions of this radar are controlled with your Garmin chartplotter. See the Radar section of your
chartplotter's owner's manual for operating instructions. To download the latest manual, go to
/manuals.
If you have more than one radar on your boat, you must be viewing the radar screen for the radar you want to
configure.
Specifying the Antenna Size
Before you can use the radar on your system, you must specify the antenna size.
1 Turn on the radar and all devices connected to the Garmin network.
An antenna-selection prompt appears on the connected chartplotters.
NOTE: If the entire system is being turned on for the first time, the antenna-selection screen is part of the
initial setup process.
2 Select the installed antenna size for each open-array radar installed on the boat.
TIP: If you need to specify a different antenna size, while viewing the radar screen for the radar you want to
change, select Options > Radar Setup > Installation > Antenna Configuration > Antenna Size, and select the
antenna size.

Front-of-Boat Offset

The front-of-boat offset compensates for the physical orientation of the radar scanner on a boat, if the radar
scanner does not align with the bow-stern axis.
