Autopilot restrictions
Important:
A SeaTalk autopilot or associated controller must not
be connected to the SeaTalk - SeaTalk
ng
converter.
There are restrictions as to how an autopilot is connected in a
system containing a SeaTalk - SeaTalk
ng
converter.
•
SeaTalk
ng
autopilot
(e.g. SPX course computer with ST70
controller) — This can be connected as part of the SeaTalk
ng
system in the usual manner. However any SeaTalk cable from the
autopilot must NOT be connected to the converter.
•
SeaTalk autopilot
(e.g. S1, S2 or S3 course computer with
ST6002 controller) — This cannot be connected to the converter,
nor to any device on the converter’s SeaTalk spur. A SeaTalk
autopilot will usually be connected directly to the multifunction
display.

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.
