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 good 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.

Installation
This product has been developed, manufactured and tested in accordance
with the requirements of EC and UL directives and the acknowledged state of
the art.
Please follow all the instructions given in this handbook exactly.
ATTENTION
Please pay attention to all text passages labeled with this
symbol. These are very important hints for operating and
security of the instruments.

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

AcquaLink® Nav Control
The AcquaLink®Nav Control unit enables skippers to assume control of
AcquaLink®TFTs in any situation.
Screens can be switched and menus and input variables navigated by using
the push / turn knob and six other push buttons. A Nav Control unit can
assume control of any display connected to the same VDO Bus with just the
push of a button. Even multiple units can be connected to the same Bus
without conflicts.

VDO Bus
The VDO BUS is an NMEA 2000-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 Nav Box 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.
Segments have to be terminated with a VDO Terminator (included in
the Nav Box box).
If you haven’t connected an instrument or Nav Control to a Nav Box
port, connect the terminator directly to the not used Nav Box 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 shouldn’t be any empty connector.
Note: VDO Bus cables have two female connectors. In order to extent
the cable length an optional gender changer connector is needed
(A2C38805500).

VDO Bus Limitations
The Nav Box 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
12V power supply:
The voltage drop for every segment of the VDO Bus is calculated as follows:
Ohm‘s Law: E (voltage drop) = I (circuit current) x R (wire resistance)
R = 2/2x Cable Length (m) x Power Pair Resistance / 100
L = Total length of VDO Bus cables in one segment
I = LEN (Load Equivalency Number) x 0.050 amps
-> E = 0.05 x LEN x L x 0.057
The voltage drop for each VDO Bus Segment shouldn’t be higher than 3V.
Note: VDO BUS has 2x AWG 22 Power/Ground cables so there is a 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 Nav Box system is 120 equals
6 Ampere.
