finding each end, and making sure they have a NMEA 2000 termination
device at each end of the backbone. If there is no pre-existing backbone you
will need to fit this before connecting the display. If you have a dual station
system you will need to connect to the NMEA 2000 network to share data
between EGM’s even if you don’t have any other NMEA 2000 equipment.
1.4 Attaching to a J1939 Engines (CAN-bus)
You will need to find the CAN-Low and the CAN-High from the Engine ECU or
off of the Transmission – see engine manual for this information. You will
then need to connect the Blue wire to the CAN-Low and the White wire to
the CAN-High. They should remain twisted together. You will also want to
check that the J1939 CAN Network is properly terminated. (You can do this
by measuring the resistance between CAN-High and CAN-Low. Once
connected it should read around 90-150 Ohms if it does not, you will need to
add a 120 Ohm resistor between the CAN-High and the CAN-Low).
1.5 Attaching to a Non-electronic Engine
In this case the engine senders will be directly connected to the display
harness. The standard minimum is for Engine Speed (Tacho), Oil Pressure and
Coolant Temperature. The display will also measure engine hours (when the
RPM is greater than 400) and battery voltage of the supply it’s connected to
(engine battery or domestic) without additional connections as these are
Automatic.

1.6 Attaching to a Rudder Angle Sender
The rudder angle can be measured from the Veethree rudder angle sender.
Connect the signal from the sender to the Yellow/White wire of the display
