ELECTRICAL SCHEMATICS
ANALOG SENSOR CONNECTION (RES 1, RES 2, RPM)
Any sensor connected to an analog input (RES 1, RES 2, RPM) of the display must be connected as shown in
the figure.
It is advisable to use sensors with isolated ground, and it is necessary to ensure that the sensor ground is
connected to the display ground to avoid incorrect readings.
EXTERNAL BUZZER CONNECTION (B1)
The display supports the connection of an external buzzer (B1) via the dedicated alarm output.
This buzzer can be powered at different voltages (consult the buzzer manufacturer's manual), as the alarm
output is connected to ground inside the display.
It is important to note that the maximum current supported is 500mA.
DAY / NIGHT MODE SELECTOR SWITCH (S1)
The display allows you to set two display illumination levels for day and night.
it is possible to switch from day mode to night mode (and vice versa) by means of a switch external to the
display (S1) connected to the power supply (KL.30), or by connecting to the lights signal onboard KL.58, if
present.
CONNECTING THE INTELLIGENT BATTERY SENSOR (IBS)
The display supports direct connection of a 12V Intelligent Battery Sensor.
This connection can be made via the Outboard Engine Kit harness, or via a special adapter cable (optional)
that allows the display to be interfaced to the battery sensor and the battery itself.
CONNECTION TO THE NMEA 2000® NETWORK
Once the installation is complete, you can interface the
device to the NMEA 2000® network through the
dedicated socket on the wiring harness.
Be sure to tighten the M12 connector by screwing it onto
its counterpart in order to preserve its watertightness.
A drop cable is not required unless the total length of the
supplied wiring is not sufficient to reach the NMEA
2000® backbone. In this case, the total length can be
extended using one of the accessory drop cables.
Note that NMEA 2000® does not allow drop cables
longer than 6 meters.
Refer to the NMEA 2000® standard for proper network
design.
