Data Master; Switching Data Master; Shared Brightness - Raymarine LIGHTHOUSE 3 Advanced Operation Instructions

Data master

Systems containing more than one MFD must have a designated Data master MFD. The Data
master is the primary MFD in the network, and should be the MFD that is physically connected to
the SeaTalkng ® / NMEA 2000 CAN bus network, and any other devices and sources of data in
your system. The Data master bridges the data over the SeaTalkhs ™ network to any compatible
networked 'repeater' MFDs.
Information shared by the Data master includes:
• Cartography
• Waypoints, Routes and Tracks
• Radar
• Sonar
• Data received from the autopilot, GNSS (GPS) receiver, instruments, transducers, the engine
and any other compatible external sources.
Note: 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.

Switching Data Master

You can switch the MFD you want to be the Data master at any time.
From the Network tab: Homescreen > Settings > Network:
1. From the list, select the MFD you want to designate as the new Data master.
2. Select Assign as Data Master from the pop-over options.
