Seatalk Connection - Raymarine 530 Owner's Handbook Manual

Chapter 6: Installation
SeaTalk is a precise, high-speed, bi-directional protocol which is flexible
enough to adapt to any number of instruments, without a central processor.
SeaTalk equipment can also communicate with non-SeaTalk equipment via
the NMEA standard.

SeaTalk Connection

SeaTalk data, if present, is the primary source for all navigational data except
heading.
The SeaTalk input/output should be connected at the rear SeaTalk 3-pin
connector. This appears as follows, when viewed from outside:

Note:
1. If you use the SeaTalk connector you must fit the supplied ferrite to the cable
for EMC CE conformance. The ferrite must be clipped to the cable as close to
the connector as possible.
2. The display does not supply 12 V via the SeaTalk connector, neither does the
SeaTalk connector require 12 V to operate.
12 V is required for other SeaTalk units.
3. If you are connecting an active compass, the NMEA input has priority. You
should, therefore use an NMEA input channel (see Power and NMEA Input
Connection) rather than the SeaTalk interface, unless the compass only has a
SeaTalk output.
To connect the display unit to the SeaTalk bus, connect a standard SeaTalk
cable between the SeaTalk connector on the rear of the display and a SeaTalk
instrument or the SeaTalk bus.
