The SeaTalk input/output should be connected at the rear SeaTalk 3-pin
connector. This appears as follows, when viewed from outside:
1. Red (No internal connection)
2. Screen (0V)
3. Yellow (Data)
SeaTalk In/Out
D3232-3
The pin functions are as follows:
Pin No. Function Colour
1 +12 V Red
2 0 V Screen
3 Data Yellow
Notes:
1 . If you use the SeaTalk connector, you must fit a ferrite (part number R55007)
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 (except where SeaTalk is connected
only between two HSB 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
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 connectors are
also available (part numbers D187 or D188), see
Section 8.2 for further details .
