2.7 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
• NMEA2000
• NMEA0183
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
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
protocols.
