HSB Series Chartplotter

HSB Connection

You can connect any two HSB displays, using an HSB cable connected

between their HSB connectors on the rear of each display unit.

Note: The HSB cables are fitted with ferrite clamps at each end to

ensure EMC conformance.

SeaTalk Connection

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:

Note: 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.

Note: The display unit does not supply 12V via the SeaTalk

connector. A separate power connection to your SeaTalk unit is

required (except where SeaTalk is connected only between two

HSB displays).

SeaTalk data, if present, is the primary source for all navigational data

except the heading (see Section 6.4).

Note: If you are connecting an active compass to the chartplotter, you

should use an NMEA input channel (see 

Power and NMEA Input

Connection

 below) rather than the SeaTalk interface, unless the

compass is connected via a SeaTalk bus.
