•

If the AIS 600 is wired to a non-Garmin NMEA 0183 chartplotter, or not wired to a chartplotter at all, then you must install a toggle switch

to turn the device on and off.

◦

Connect the yellow wire from the AIS 600 power/data cable to one terminal of a single-pole, single-throw switch (not included), and

connect the other terminal to the negative (-) battery terminal.

◦

When you close the switch, the AIS 600 powers on. When you open the switch, the AIS 600 powers off.

Installing the GA 30 GPS Antenna

You must install the included GA 30 GPS antenna and connect it to the AIS 600 according to the following instructions. The AIS 600 will not

transmit a signal unless the GA 30 is installed properly and receiving a satellite signal.

The AIS 600 does not accept GPS information from any other GPS device or antenna on the boat. Also, the AIS 600 does not share GPS

information from the GA 30 antenna with any other device on the boat.

You can surface mount the GA 30 antenna or attach the antenna to a standard 1 in. OD (14 threads per inch) pipe-threaded-pole marine mount

(not included).

Select a suitable location for the GA 30 antenna on your boat. To ensure the best reception,

mount the GA 30 antenna in a location with a clear view of the sky in all directions.

•

Avoid mounting the GA 30 antenna in the shade of the superstructure of the boat, a radome

antenna, or a mast.

Mount the GA 30 antenna at least 3 ft. (1 m) away from (preferably above) the path of

•

any radar beam or a VHF radio antenna.

Temporarily secure the antenna in the preferred mounting location and test it for correct

operation. If you experience interference from other electronics, try a different location. When

you verify correct operation, permanently mount the antenna.

Surface-mounting the GA 30 Antenna

1 Use the surface-mount bracket as a mounting template.

•

Use a center punch to mark the three screw locations on the surface.

•

Use a pencil to trace the cable hole in the center of the bracket.

•

Set the surface-mount bracket aside. Do not drill through the surface-mount bracket.

2. Drill

in. (3 mm) pilot holes at the three marked locations.

NotE: If you are mounting the GA 30 on fiberglass, it is recommended that you

use a countersink bit to drill a clearance counterbore through the top gelcoat layer

(but no deeper). This will help to prevent cracking in the gelcoat layer when the

screws are tightened.

3. Use a 1 in. (25 mm) hole saw to cut the cable hole in the center.

4. Place the seal pad on the bottom of the surface-mount bracket. Ensure that the

screw holes align.

5. Use the included M4 screws to attach the surface-mount bracket to the mounting

surface.

6. Route the cable through the 1 in. (25 mm) cable hole and connect it to the GA 30.

7. Ensure that the large rubber gasket is in place on the bottom of the GA 30

antenna, place the antenna on the surface-mount bracket

antenna clockwise to lock it in place

8. Secure the antenna to the mounting bracket with the included M3 set screw

9. Route the cable away from sources of electronic interference, and connect it to the

AIS 600 using the BNC connector.
