Chapter 2: Installing the system
NMEA 0183 equipment
The SPX-5 Wheel system can connect to NMEA devices such as a GPS or
chartplotter.
Data bridging
The SPX-5 Wheel system acts as a bridge between SeaTalk and NMEA, allowing
NMEA and SeaTalk devices to share information.
For example, the information received from an NMEA GPS could be shared with a
SeaTalk instrument to provide a separate Course Over Ground display.
