Always check the installation before going to sea to make sure that it is not
affected by radio transmissions, engine starting etc.
8.8 Integrated Systems
The
hsb
2
series displays can be linked to other equipment to transfer data as
follows:
•
Additional displays, either CRT or LCD, can be connected via
hsb
2
(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.
Power for External Equipment
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:

You can connect several
hsb
2
displays; the number is dependent on cable
length - see hsb2 Cable on page 8-8. The system can include existing HSB
display units that have been suitably upgraded - contact your authorized
Raymarine dealer for upgrade kit details.
