NOTE: The Gateway will not provide the operating power for devices on the NMEA 2000 network. The NMEA 2000 network
will require its own power source. The NMEA power input should be switched and have appropriate circuit protection.

Installing the Gateway
Fasten the Gateway module one of the two following ways:
1. Fasten the Gateway module with the screws provided.
2. Attach the Gateway module to an adjacent wiring harness with the cable ties provided.
Guidelines for Installing Harnesses
Follow these guidelines when installing the harnesses:
• The maximum CAN bus length is 70 m (230 ft).
• The maximum length of a CAN bus drop (branch off the main harness) is 7 m (23 ft).
• The combined length of all drops cannot exceed 36 m (118 ft).
• Locate an appropriate path for routing the harness connections to their installation points.
• Inspect the routing path to ensure that the surfaces are free of any sharp edges or burrs that could cut the harness.
• Fasten and support the harness with clamps or cable ties along the routing path. A clamp or cable tie must be used
within 25.4 cm (10 in.) from any connection and every 45.8 cm (18 in.) along the routing path if not housed in a rig tube.
• Ensure that all connections are tight and locked (if equipped with a lock mechanism).
• Seal all unused connectors with weather caps.
• Route the harness at least 1 m (3 ft 3 in.) from any device that produces electromagnetic interference (EMI), such as
VHF radio and radar equipment.
Precautions for Wiring and Harnesses
IMPORTANT: Refer to the following precautions to avoid damage to the electrical system when working on or around the
electrical harness or when adding other electrical accessories.
• Do not attempt diagnostics without the proper approved service tools.
• Do not puncture wires for testing (probing).
• Do not splice wires into the harness.
• Do not connect, network, tie into, switch, or sink source voltage or current from the wiring harnesses.
• Do not connect any type of communication or navigation equipment into the wiring harnessing other than at the
designated connection point.
• Install boat accessory equipment using an appropriate power source connection, such as a fuse panel or junction box
circuit breaker.
• Do not tap directly into any of the electrical wiring harnesses for a source of power.

Troubleshooting
Operation of the Gateway can be checked by observing the CAN light and NMEA light. Refer to the following chart:
Gateway Module Light Functions
Light Function
CAN NMEA
on on
Gateway module is connected to both the CAN bus and NMEA bus. Data will be
transferred as required.
NOTE: If there is no data coming from the NMEA bus to the CAN bus, approved NMEA
devices are not used on the boat.
off on
1. Gateway module is connected to the NMEA bus and is receiving the data on the
bus.
2. Gateway module is not connected to the CAN bus. Check the connections on the
CAN bus accordingly.
3. Power is not present at the CAN 10 pin harness connector.
on off
1. Gateway module is connected to the CAN bus and is receiving the data on the
bus.
2. Gateway module is not connected to the NMEA bus. Check the connections on the
NMEA bus accordingly.
3. Power is not present at the NMEA 2000 harness connector.
off off
1. Gateway module is not connected to the NMEA and CAN bus. Check the
connections on both sides accordingly. If the connections are deemed good, the
Gateway module may require replacement.
2. Power is not present at the Gateway CAN 10 pin harness connector nor the NMEA
2000 harness connector.
blink (connected to NMEA 2000
only)
There is an intermittent connection on the circuit side of the Gateway where the light
blinks. Check the harness and connections accordingly.
blink (connected to NMEA 0183) NMEA light will blink for normal operation. Refer above for CAN light blink.
