Connecting The Gdl 30/30A To A Chartplotter; Connecting The Audio Cable (Ga 30A Only); Mounting The Ga 31 Antenna - Garmin 30 Owner's Manual

Connecting the GDL 30/30A to a Chartplotter

Connect the GDL 30/30A to one chartplotter by using the Garmin Marine
Network Cable (included). If you need to connect the GDL to multiple
chartplotters, a GMS 10 Network Port Expander is required.
Do not cut the Garmin marine network cable if you need to drill a hole in your
boat; use the included grommet that is specifically designed to cover holes that
are drilled for the Garmin Marine Network Cable. If a longer cable is needed,
contact Garmin or your Garmin dealer. To ensure safety, use tie-wraps, fasteners,
and sealant to secure the cable along a route and through any bulkhead or deck.
To connect the GDL 30/30A to a chartplotter:
Plug the Marine Network Cable into the NETWORK connector on the GDL
30/30A and the back of the chartplotter.
Use a Network Port Expander to connect the
GDL 30/30A to multiple chartplotters
Connecting the GDL 30/30A to more than one chartplotter requires a Garmin GMS 10
Network Port Expander (not included). The GMS 10 provides additional network ports,
allowing the use of multiple chartplotters and additional sensors.

Connecting the Audio Cable (GA 30A only)

Connect the Audio cable (included) to the GDL 30/30A AUDIO connector and
to the audio inputs on your stereo receiver.

Mounting the GA 31 Antenna

The GA 31 is designed to fit a standard 1-inch, 14 threads-per-inch marine
antenna mount. Since mounting locations and methods vary, determine the best
mounting location for the GA 31 then obtain a suitable mount from your Garmin
dealer or a marine supply retailer.
When selecting a mounting location keep these factors in mind:
• The GA 31 works best with an unobstructed view of the sky and horizon.
• Avoid routing the antenna cable near ignition wires and along the same
path as power wires.
• Do not cut or shorten the antenna cable. The length of the antenna cable
is set to provide optimal performance. Shortening the cable adversely
effects the GA31's performance.
• If additional antenna cable is needed, Garmin recommends a 50 foot cable
from Delphi, part #SA10006. The following adapters are required; BNC
plug to SMB jack - available from Newark, part #92C7329, BNC jack to
SMB plug - available from Newark, part #92C7330
To connect the GA31 to the GDL 30/30A:
Place the GA 31 connector onto the GDL 30/30A ANTENNA connector
and twist clockwise to secure.
Check the antennas performance with potential interfering equipment turned
on and off before permanently mounting the antenna. Perform this test after the
XM WX Weather service is activated. Following is a list of items that could
potentially cause interference: other electronic equipment, fan motors, the engine
ignition system, alternators, generators, radar, and VHF radio transmissions. After
proper operation is verified, permanently install the antenna.
