1. Can I connect your device directly to an MFD?
In case of NMEA 2000, no. You should establish a basic NMEA 2000 network first, it requires a backbone with dedicated power source (Fig. 1, item 5) and termination resistors (Fig. 1, item 3).
NMEA 0183 connectors of the NMEA 0183 Multiplexer, NMEA 2000 Wi-Fi Router, NMEA 0183 Wi-Fi Router, NMEA 0183 Wi-Fi Gateway YDWN-02 and NMEA 0183 Gateway YDNG-03 can be connected directly to the NMEA 0183 port or SeaTalk port of a chart plotter.
