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.
In an autopilot system which does not contain a
dedicated pilot control head the Data master also
acts as the control for the autopilot.
