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:

(High Speed Bus) Multiple Display Systems
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.
