3.9 Data master
Any system containing more than one networked multifunction
display must have a designated data master.
The data master is the display which serves as a primary source
of data for all displays, it also handles all external sources of
information. For example the displays may require heading
information from the autopilot and GPS systems, usually
received through a SeaTalk
ng or NMEA connection. The data
master is the display to which the SeaTalk, NMEA and any
other data connections are made, it then bridges the data to
the SeaTalk
hs network and any compatible repeat displays.
Information shared by the data master includes:
• Cartography
• Routes and waypoints
• Radar
• Sonar
• Data received from the autopilot, instruments, the engine and
other external sources.
Your system may be wired for redundancy with data connections
made to repeat displays. However these connections will only
become active in the event of a fault and/or reassignment of
the data master.
