Garmin VHF 300 AIS Manual de instrucciones de instalación

To create a basic NMEA 2000 network:

1. Connect two T-connectors (not included) together by their sides.

2. Connect a NMEA 2000 power cable (not included) to one of the T-connectors.

NotICe: A NMEA 2000 power cable must be connected to a 12 Vdc power source through a switch. The NMEA 2000 network may drain your

battery if it is connected directly. Connect the cable to the ignition switch of the boat if possible, or through an appropriate additional switch.

3. Connect a NMEA 2000 drop cable (not included) to the other T-connector and to the NMEA 2000 port on the VHF 300 Series transceiver

box.

4. Add additional T-connectors for each device you add to the NMEA 2000 network, and connect each device to a T-connector with a drop

cable.

5. Connect terminators (not included) to each end of the combined T-connectors.

Connecting the VHF 300 Series to a NMEA 0183 Device

The following diagram illustrates the NMEA 0183 wiring used to connect your VHF 300 series radio to a GPS chartplotter.

Connect NMEA 0183 bare wires as indicated in the following illustration. Use 22 AWG wire for extended runs of wire, if needed.

NotICe: Cover the connections with a waterproof, adhesive tape, such as rubber vulcanizing tape, to prevent water from seeping into the radio.

Connecting the VHF 300 Series Radio to a Hailer Horn (Optional)

1. Follow the mounting instructions provided by the manufacturer of your hailer horn if it is not already mounted.

2. Consult the manufacturer of your hailer horn to identify the positive and

negative wires or terminals.

3. Use the VHF 300 Series Hailer-Horn Wiring Assignment Table to identify the

positive and negative wires.

4. Wire the correct positive and negative wires from the VHF 300 power/data

cable to the passive speaker.

5. Use 22 AWG wire for extended runs of wire, if needed.

NotICe: Cover the connections with a waterproof, adhesive tape, such as rubber vulcanizing tape, to prevent water from seeping into the radio.
