NavBox Electronic Control Unit

The AcquaLink NavBox is the core of the AcquaLink VDO Marine system. It acts as a CPU and signal interface. The NavBox provides a wide range of digital and analog input possibilities. It supports up to four electronic engines (J1939 or NMEA 2000) or one analog engine. It also features two VDO Marine Sumlog paddle wheel sensor and one analog VDO Marine Windsensor connections, so legacy VDO Marine products can be used and brought to the digital age.

NavSensor reads following analog data:

• Engine Oil Pressure


• Engine Oil Temperature


• Engine Coolant Temperature


• Transmission Oil Pressure


• Fresh Water, Waste Water and Fuel Level


• Voltage


• Rudder Angle


• Engine Frequency


• Battery Current


• Pyrometer

It also features a NMEA 0183 input and output port as well as a buzzer output. All received data are converted and sent to the NMEA 2000 network and to the VDO Marine Bus. This gateway function allows displaying engine, liquid level, pressure, temperature and other vital information on any compatible display on the NMEA 2000 network or on designed VDO Marine AcquaLink gauges or TFT Displays.

The configuration of the NavBox can be done by using an AcquaLink TFT and NavControl or by using the intuitive VDO Marine diagnostic tool.
