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).
