Safety Instructions
DANGER!
Before beginning work, the
negative Terminal of the battery
should be disconnected!
• Use of information provided by
the VDO system does not release
you from the responsibility over
your ship and demands well
seamanship. Always use your
nautical experience in interpreting
the displayed values.
• If you carry out this work yourself,
wear suitable working clothes. Do
not wear wide fitting clothes. If you
have long hair, wear a hair-net.
Clothes and hair can get caught in
moving and rotating parts.
• Wearing of metallic or conductive
jewellery, such as necklaces,
bracelets, rings etc. is not allowed
when working on the electrical
installation on board.
• Please note that with
disconnection of the battery, all
volatile electronic memories lose
their input values and must be
reprogrammed.
DANGER!
Explosion hazard!
Before beginning work on the engine compartment of petrol engines, switch on the ventilator of the
engine compartment.
• Ensure that necessary clearance
is provided behind the cable
opening, at the position where
the gauge is to be installed.
• When selecting the installation
position for gauges or displays,
take care that no stringers
are drilled. Be careful also
of furniture, floorboards,
superstructure boxes, cables
etc.
• When carrying out installation
work with a sealing compound,
solvent vapours can be
formed. Make sure of adequate
ventilation and follow the
instructions for use of the sealing
compound manufacturer.
• Please note, that the Nav Box is
not a ISO8846 certified product
and should not be installed
inside the engine compartment.

2.2 Preliminary Remarks
• For the installation only use VDO
and NMEA 2000 approved cables.
• If you don’t use standard cables, the
wires used should be adequately
insulated or should have sufficient
electrical strength, and the contact
point should be protected against
electrical shock hazard. The
electrical conducting components
of the connected consuming
devices should also be protected
against direct contact through
suitable measures. Installation of
bare metallic wires and contacts is
not allowed.
• Take account of the wire cross
section. A reduction of the wire
cross section results in a higher
current density. This can cause
the wire to heat up and potentially
cause fire.
• Connect the wires only in
accordance with the wiring diagram.

2.3 Safety Instructions for
Maintenance
The VDO Nav Box system is maintenance-free. Do not use cleaning
agents.
Repairs on the system should be carried out only by VDO authorized specialists !

The Nav Box System
3. The Nav Box System
The Nav Box is the heart of the VDO
AcquaLink system. To operate the
AcquaLink system you need the Nav
Box, at least one AcquaLink 4.3’’TFT
and one Nav Control. The sytem can
be accomplished with 110mm and
52mm gauges and a wide array of
sensors and transducers.
Additionally the Nav Box converts
SAE J1939 and analogue signals to
NMEA 2000.
In order to program and adjust the
system you need to refer to the
NavBox operation manual. This instruction focuses on the installation
and the connection of the NavBox to
optional sensors and transducers.
3.1 Installation of the Nav Box
In the Box:
• Nav Box
• 3 pin power cable
• 26 pin cable for analogue input
• Mounting screws
• Installation instruction
• Mouting template
• Operation manual
• 3x VDO Bus terminators
8
Please use the mounting template to
determine a proper installation location. The Nav Box can be mounted
horizontally but it is recommended
to mount the unit vertically on a bulkhead or other structure with the
cable connections pointing to the
bottom. This helps water to run off
and protect the cables from bending
and chafng.
You also have a better access to the
status LEDs on top of the unit.

NMEA 2000 Engine Support
The Nav Box system supports up to
four NMEA 2000 engines. The engines
have to be properly programmed with
individual instance numbers (0-3) by
an engine technician.
Please refer to the Operation manual
to set up the Tachometers with the
right instance numbers.

SAEJ1939 Installation
Important:
If you use any of the three SAEJ1939
ports you need to terminate all three
SAE J1939 ports with three 180 ohm
resistors!
VDO offers an optional 180 ohm inline
terminator (A2C99794200).
Data Handling
The Nav Box has an interface that is
SAEJ1939 Multi Engine support
Four Engines in one CAN Bus system
SAE J1939 compatible. It is used to receive en gine data and distributes them
over VDO Bus and NMEA 2000 to make
them available for both the NMEA2000
network and the AcquaLink system.
The Nav Box also receives all
DM1 DTC messages of the SPN List
above.

VDO Bus
The VDO Bus is an NMEA2000-based
communication used within the Acqualink system to share the information
gathered from the system interfaces as
well as to distribute proprietary messages containing status information of the
system itself. The VDO Bus uses M12 8
Pin cables and all devices are powered
through the network.
The NavBox has three VDO Bus ports,
so three separate VDO Bus segments
can be installed. This helps to reduce
the power drop in the system and allows an easy installation in all areas of
the vessel.
Every 110mm gauge, 4.3’’ TFT
and Nav Control features two
equal VDO Bus connectors in the
rear.
The units are daisy chained together.
17
Page 18
VDO Bus
Important:
• All three VDO Bus segments have to
be terminated with a VDO Terminator
(included in box).
• If you haven’t connected an
instrument or Nav Control to
a Nav Box port, connect the
terminator directly to the not used
NavBox VDO port.
• If you have connected displays or
gauges, use the terminator on last
empty VDO port on the last unit in
the chain.
• There mustn't be any empty
connector
VDO Bus Limitations
Note:
VDO Bus cables have two female connectors. In order to extent the cable
length an optional gender changer
connector is needed (A2C38805500).
18
The NavBox provides power to all the
110mm gauges and 4.3’’ TFTs connected to the system. Due to the power
consumption and the resistance of the
cables, there are limitations of the maximum cable length and number of
possible instruments in the system.
In order to have a properly working
system the voltage drop of every of the
three VDO Bus segments have to be
calculated.
1 LEN = 0.05 Ampere

Calculation
Calculation
12V power supply:
The voltage drop for every segment of
the VDO Bus is calculated as follow:
Ohm‘s Law: E (voltage drop) = I (circuit
current) x R (wire resistance)
R = 2/2x Cable Length (m) x Power
Pair Resistance / 100
I = LEN (Load Equivalency Number) x
0.050 amps
L = Total length of VDO Bus cables in
one segment
-> E = 0.05 x LEN x L x 0.057
The voltage drop for each VDO Bus
Segment shouldn’t be higher than 3V
4.4 VDO Sensor
You can connect the VDO Navsensor
and VDO NMEA 2000 Windsensor directly to the NavBox without using the
NMEA 2000 Network
Note:
VDO Bus has 2x AWG 22 Power/
Ground cables -> so there is different
voltage drop calculation than NMEA
2000.
24V power supply:
If using a 24V system the voltage drop
may not be higher than 9V.
Note:
The maximum Number of LEN in the
NavBox system is 120 equals 6 Ampere.
Note:
One 120ohm resistor has to be installed as close as possible to the sensor.

NMEA 0183
4.5 NMEA 0183
The NavBox can receive NMEA 0183
data and distributes it over VDO Bus
and NMEA2000 to make them available for both the AcquaLink system and
the NMEA 2000 network.
The NavBox supports following NMEA
