3.4 System protocols
Your product can be connected to various products and systems
to share information and so improve the functionality of the
overall system. These connections may be made using a
number of different protocols. Fast and accurate data collection
and transfer is achieved by using a combination of the following
data protocols:
• SeaTalk
ng
• NMEA 2000
• SeaTalk
Note:
You may find that your system does not use all of the
connection types or instrumentation described in this section.

SeaTalk
ng
(Next Generation) is an enhanced protocol for
connection of compatible marine instruments and equipment. It
replaces the older SeaTalk and SeaTalk
2
protocols.
SeaTalk
ng
utilizes a single backbone to which compatible
instruments connect using a spur. Data and power are carried
within the backbone. Devices that have a low draw can be
powered from the network, although high current equipment will
need to have a separate power connection.
SeaTalk
ng
is a proprietary extension to NMEA 2000 and the
proven CAN bus technology. Compatible NMEA 2000 and
SeaTalk / SeaTalk
2
devices can also be connected using the
appropriate interfaces or adaptor cables as required.
NMEA 2000
NMEA 2000 offers significant improvements over NMEA 0183,
most notably in speed and connectivity. Up to 50 units can
simultaneously transmit and receive on a single physical bus at
any one time, with each node being physically addressable. The
standard was specifically intended to allow for a whole network
of marine electronics from any manufacturer to communicate on
a common bus via standardized message types and formats.
SeaTalk
SeaTalk is a protocol which enables compatible instruments to
connect to each other and share data.
The SeaTalk cable system is used to connect compatible
instruments and equipment. The cable carries power and data
and enables connection without the need for a central processor.
Additional instruments and functions can be added to a SeaTalk
system, simply by plugging them into the network. SeaTalk
equipment can also communicate with other non-SeaTalk
equipment via the NMEA 0183 standard, provided a suitable
interface is used.
