The AcquaLink® NavBox is the core of the AcquaLink® VDO 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 analogue engine. It also features two VDO Sumlog® paddle wheel sensor and one analogue VDO Windsensor connections, so legacy VDO products can be used and brought to the digital age. NavBox reads following analogue data: • Engine Oil Pressure • Engine Oil Temperature • Engine Coolant Temperature • Transmission Oil Pressure • Fresh Water, Waste Water and Fuel level • Ammeter • Rudder angle • Engine frequency • Pyrometer • Ammeter 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 Bus. This gateway function allows displaying engine, liquid level, pressure, Temperature other vital information on any compatible display on the NMEA 2000® network or on designed VDO 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 diagnostic tool.
