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.
