The 

hsb

 series displays can be linked to other equipment to transfer data as 

follows:

•

Additional displays, either CRT or LCD, can be connected via 

hsb

 (and 

SeaTalk) to repeat fishfinder, chart and/or radar information at a remote 
location. 

•

Data can be received via SeaTalk or NMEA, some of which will increase 
the functionality of the display. Other data can be viewed on the display.

•

Data can be transmitted via SeaTalk and NMEA to enhance other equip-
ment.

•

Some incoming data can be converted across the communication link and 
re-transmitted - see Data Conversion on page 8-30.

External equipment cannot be powered from the display’s SeaTalk 
interface. It must be powered from the ship’s supply or via a SeaTalk bus. 
Ensure correct polarity of the SeaTalk connection.

For systems where the ship’s power source is 24 V only, you may need to 
install a 24 V to 12 V DC converter. This is only necessary if the products 
being connected to the display are:

•

SeaTalk compatible (for example, compass, GPS and instruments), and 
there is no existing SeaTalk bus

•

NMEA compatible, but operate only from 12 V (for example, compass, 
GPS and some navigators)

The DC~DC converter must conform to the following specification:

hsb

You can connect several 

hsb

 displays; the number is dependent on cable 

length - see hsb

 Cable on page 8-9. The system can include existing HSB 

display units that have been suitably upgraded - contact your authorized 
Raymarine dealer for upgrade kit details.
