Connection / Cable Notes
Backbone cables (various lengths) The main cable carrying data. Spurs
from the backbone are used to
connect SeaTalk
ng devices.
T-piece connectors Used to make junctions in the
backbone to which devices can then
be connected.
Terminators Required at either end of the
backbone.
Spur cables Used to connect devices. Devices
may be daisy chained or connected
directly to the T-pieces.
Seatalk ng power
The SeaTalk ng bus requires a 12 V power supply. This may be
provided from:
• Raymarine equipment with a regulated 12 V supply. (e.g. a
SmartPilot SPX course computer)
• Other suitable 12 V supply.
Note: SeaTalk ng does NOT supply power to multifunction displays
and other equipment with a dedicated power supply input.
3.12 NMEA 2000 connection
The display can receive data from NMEA 2000 devices (e.g. data
from compatible engines). The NMEA 2000 connection is made
using SeaTalk
ng and appropriate adaptor cables.
You can EITHER:
• Use your SeaTalk ng backbone and connect each NMEA 2000
device on a spur, OR
• connect the display on a spur into an existing NMEA 2000
backbone.
Important: You cannot have 2 backbones connected together.
