C-Series protocols

Your C-Series Widescreen Multifunction Display can connect to
various instruments and displays to share information and so
improve the functionality of the 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

hs

• SeaTalk

ng

• NMEA 2000

• SeaTalk

• NMEA 0183

Note: You may find that your system does not use all of the
connection types or instrumentation described in this section.

SeaTalk

hs

SeaTalk

hs

is an ethernet based marine network. This high speed

protocol allows compatible equipment to communicate rapidly and
share large amounts of data.

Information shared using the SeaTalk

hs

network includes:

• Shared cartography (between compatible displays.

• Digital radar data.

• Sonar data.

Seatalk

ng

SeaTalk

ng

(New 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 cable 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.

NMEA 0183

The NMEA 0183 Data Interface Standard was developed by
the National Marine Electronics Association of America. It is an
international standard to enable equipment from many different
manufacturers to be connected together and share information.
