SeaTalk Connection

This connection is necessary for full functionality between hsb2 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:

SeaTalk In/Out
1.	Red (No internal connection)
2.	Screen (0V)
3.	Yellow (Data)
	D3232-3

Figure 8-16:	SeaTalk Connector
Table 8-5:	Sea Talk Connections
Pin No.	Function	Color
1	+12 V	Red
2	0 V	Shield
3	Data	Yellow

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 (except where SeaTalk is connected only between two hsb2 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.
