INTRODUCTION
VMH35 is a NMEA 2000 certified device designed for
monitoring outboard engines.
Equipped with analogue inputs it is also well suited to
refitting older engines allowing the direct connection of
various sensors such as fuel, trim and tachometer, while
the built-in NMEA 2000 gateway distributes these
measurements to other digital network devices such as
chartplotters, saving the need for an external converter.
Its sleek black glass design is complemented by a
stainless-steel frame crimped onto the mineral glass
front where the sunlight-readable hybrid display is
glued.
The VMH35 has an IP X7 protection rating from the front
and back to ensure the best performance in outdoor
environments.
The built-in GPS makes the VHM35 the perfect
standalone solution by integrating speed, compass and
position data with engine information, while the
dedicated IBS input allows you to interface an external
12V smart battery sensor to keep your boat's energy
supply under control at all times
ARCHITECTURE
OPERATION
The VMH35 indicator is a versatile device. It allows the operation of all connected motors to be monitored at the same time.

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 the direct connection of an intelligent 12V battery monitoring sensor.
This connection can be made through a special adapter cable (optional) that allows you to interface the display 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.
Fare riferimento allo standard NMEA 2000® per una
corretta
