Installing the Displays
The EGM supports up to three engine types (Non-electric, J1939 or NMEA
2000) and each display can be allocated to be Port (or single), Starboard or
Centre. When mounting the displays the allocation of position is not
important as this is done during the commissioning sequence. Multi station
capability is a built-in feature and is provided across the NMEA 2000 network
using the gateway function. Adjustable items like language selection and
backlight are shared across the network so that all displays are synchronised
with the same settings.
1.1 Mounting the Display
Contained in the box you have received is a Fixing template, place this on the
area where the display is to be fitted, and use it to mark the holes in the
Dash, Fit the studding, from the “Fitting Kit” supplied, into the four positions
at the rear of the display. Make sure the Rubber Seal is securely in place at
the rear of the display over the USB Port access and then feed the studding
through the four holes and use the nuts to fix the display in place. The display
has an integrated rubber gasket to help seal the display to the dash.
Depending on access you may also need to fit the supplied cable harness to
the display before mounting the display.
1.2 Power Connections to the Display (all engine types)
The display can be powered from the engine battery, this way the display will
be able to monitor the engine battery voltage, however, while the engine is
cranking the display may cut out. Alternatively you can connect the display to
the domestic battery supply; this will prevent cut outs while the engine is
cranking. In either case the supply is fed via the black and red wires on the
harness (there are two blacks and either can be used). The supply should be
fused at 500mA or 1A max to protect the wiring.
1.3 Attaching to NMEA 2000 (optional)
Find the NMEA 2000 backbone if already fitted on the vessel, and use a T-
Piece to connect the NMEA 2000 Cable from the display to the backbone. You
should check that the NMEA backbone is properly terminated, you do this by
