Connecting the Device to Power

WARNING

When programmed with a valid MMSI number, this device allows you to transmit AIS signals with vessel position data. This device is meant to enhance situational awareness and may not prevent vessel collisions in all circumstances. It is your obligation to be aware of your surroundings and to ensure safe operation of the vessel.

CAUTION

After installing the device and programming a valid vessel MMSI number, you can temporarily revert to the default silent mode (only receives, does not transmit) using a toggle switch (not included) (). While operating in silent mode, the device does not transmit AIS signals.

Four wires (red, black, green, and yellow) provide the basic power connection.

  1. Route the wiring harness 1 from the device POWER (and NMEA® 0183) port 2 to the battery 3.

  2. Connect the red wire 4 to the positive (+) battery terminal.
  3. Connect the black wire 5 to the power ground on the negative (-) battery terminal.
  4. Connect the green wire 6 to the power ground with a switch (not included) between the green wire and power ground, to provide a toggle 7, 8 switch to revert to the default silent mode (optional).
  5. Complete an action, based on the network type:

    • In a NMEA 0183 system, connect the yellow wire (Accessory On) 9 to the power ground, and install a switch (not included) between the yellow wire and the power ground.

      NOTICE

      Turning off the switch prevents the device from draining the battery when the engine is off.

    • In a NMEA 2000® system, the device automatically powers on and off with the system, and you do not need to connect the yellow Accessory On wire.
