System Protocols; Tools Required - Raymarine i50 Depth Installation And Operation Instructions Manual

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
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
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.
