CAN P Multiengine Gateway—Single Engine through Quad
NOTE: The Gateway module does not provide power for any device on the NMEA 2000 network. The NMEA 2000 network
will require its own power source. The NMEA power input must have appropriate circuit protection for the devices on the
NMEA 2000 network.

Installing the Gateway
Fasten the Gateway module in one of the two following ways:
1. Fasten the Gateway module with the screws provided.
2. Secure 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 the harness is not housed
in a rigging 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 to the wire 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.

CAN P Multiengine Gateway Module Harness Connections
For multiengine installations all engines must be networked on the CAN P bus. To ensure proper Gateway operation it must
be connected to a 10‑pin connection that receives a wake signal from any key switch. The two most common methods are
listed below. Refer to 14‑pin architecture drawings for more detail.
NOTE: Data is carried from the SmartCraft junction box to the Gateway module on the CAN P data bus.

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 (Engine and Helm)
Light Function
CAN NMEA
On On
1. The Gateway module is connected to both a functioning CAN bus and NMEA 2000
bus. Data will be transferred as required.
2. Update/verify chartplotter software (consult manufacturer's website).
3. If Data is not being transferred NMEA 2000 bus device ID's are not approved and
are being blocked. Contact Mercury Marine service for helm Gateway (autopilot)
device approval list.
Off On
1. The Gateway module is connected to the NMEA 2000 bus and is receiving the data
on the bus.
2. The 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. The Gateway module is connected to the CAN bus and is receiving the data on the
bus.
2. The Gateway module is not connected to the NMEA 2000 bus. Check the
connections on the NMEA bus accordingly.
3. Power is not present at the NMEA 2000 harness connector.

1. The Gateway module is not connected to the NMEA 2000 or 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 at the
NMEA 2000 harness connector.
Blink (connected to NMEA 2000
only)
The circuit has an intermittent connection. Check the NMEA 2000 harness and
connections accordingly.
Blink (connected to NMEA 0183) NMEA light will blink for normal operation. Refer above for CAN light blink.
