For the most part, the NMEA network on Sabado is how she came from the factory. We are sharing it here to show how we’ve integrated our monitoring systems into what was existing. This type of integration should be an option regardless of the brand of navigation equipment installed as long as they are networked with NMEA equipment. You may need to invest in one of the adapters/converters that are readily available on the market if your system uses proprietary connections or communication protocols.

We have several ways that we can pull data into our custom monitoring systems.  Firstly, because we’ve integrated the B&G systems into our computer network, we can use either Ethernet or WiFi to collect and monitor the NMEA data.  When the navigation system is powered up, we pull data from both the Yacht Device Ethernet gateway and the B&G Zeus multi function device (MFD). These systems each forward data that the other doesn’t. Yes, you would think there would be better standards but there isn’t. When the navigation system is powered down, we still pull GPS, AIS, and speed from the Vesper Cortex WiFi.  This allows us to maintain a robust anchor watch alarm system without the need to keep the entire system powered up.

Some notable additions that we’ve made to the NMEA device list includes the yacht device engine gateways that add all of our engine data to the system and the Victron Cerbo GX that adds all of the electrical and tank level data.

You’ll also see that we’ve added a fully independent backup autopilot to the equipment list. This system is not connected to the main NMEA network. Instead, the backup system maintains its own “private” NMEA network that operates independent of the main network. This is done mainly for protection against electrical surges such as those from nearby lightning strikes.

Finally, we have three independent sources of GPS data that is connected to the network at all times as well as two sources of GPS data that we keep unplugged as backups. Overkill?  Maybe, but we like redundancy.
