SeaTalk Connection
This connection is necessary for full functionality between hsb

series
displays. 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:

the connector as possible.

SeaTalk connector require 12 V to operate.
12 V is required for other SeaTalk units (except where SeaTalk is connected
only between two

displays).
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) rather than the SeaTalk interface, unless the com-
pass 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. For multi-display systems, use a SeaTalk
Junction 3-way block (part number D244) at each display.
Standard SeaTalk cables are available in a range of lengths (part numbers
W284 to W287), and cables for connecting to SeaTalk units with round
connectors are also available (part numbers D187 or D188), see Section 8.2
for further details.
