Seatalk Connection - Raymarine SL72 Owner's Handbook Manual

Chapter 8: Installation

SeaTalk Connection

SeaTalk data, if present, is the primary source for all navigational data except
heading.
Note: On the SL72 PLUS Radar display you can connect either SeaTalk input/
output or NMEA output, but not both. Ensure that the Data Selection option in
the System Set Up menu is set correctly.
The SeaTalk input/output should be connected at the rear SeaTalk 3-pin
connector. This appears as follows, when viewed from outside:

Notes: 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 to the radar, the NMEA input has
priority. You should, therefore use an NMEA input channel (see Power and
NMEA Input Connection on page 8-22) rather than the SeaTalk interface, un-
less 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.
Standard SeaTalk cables are available in a range of lengths (part numbers
W284 to W287), and cables for connecting to SeaTalk units with round
