The MDI system
The MDI is located on the engine and is connected to
a number of nearby components, such as sensors,
switches, button panel and instruments.
A data link (CAN bus) links the MDI to the tachome-
ter/display and other optional equipment such as
NMEA2000 interface, multisensor.
Functionality
Instrumentation
The instruments use a serial communication bus. The
serial communication bus in combination with EVC
reduces wiring and simplifies installation.
EVC system tachometer
All alarms are available in the tachometer. The ta-
chometer has a built in buzzer alarm and an output to
the instrument serial bus (easy-link).
EVC system display
The EVC system display is a complement or replace-
ment for the EVC system tachometer and optional in-
struments. The display shows operation information,
information messages and alarms. The user selects
what operation information to display with the buttons
on the display. The EVC system display can show
more than one operation information at one and the
same time. The display also has access to the same
display mode and calibration functions as for the EVC
system tachometer display.
Fuel level
If a fuel level gauge is used it must be connected to
the instrument serial communication bus (easy-link).
The MDI has an input for the fuel level sender.
NMEA support
The MDI system supports NMEA 2000 by means of a
hardware interface.
Boat speed, echo sounder and water temp
(Multisensor)
The multisensor is connected to the multilink cable.
Data from the multisensor are shown in the EVC dis-
play and the speedometer instrument.
