J1939 Engine Network Connection Considerations
You must use a Garmin GPSMAP J1939 accessory cable when connecting the chartplotter to the J1939 engine
network to prevent corrosion due to moisture. Using a different cable voids your warranty.
If you have an existing engine network on your boat, it should already be connected to power. Do not add any
additional power supply.
This chartplotter can connect to an engine network on your boat to read data from compatible devices such as
certain engines. The engine network follows a standard and uses proprietary messages.
You should consult the manufacturer of your engine or engine network when connecting the chartplotter. Some
manufacturers may have requirements you must follow when connecting to avoid unexpected behavior.
The port labeled J1939 is used to connect the device to the existing engine network. You must route the cable
within 6 m (20 ft.) of the engine network backbone.
The Garmin GPSMAP J1939 accessory cable requires connection to a power source and proper termination. For
more information on connecting to your engine network, see the manufacturer's engine documentation.
