HSB Series LCD Display
8.8 Integrated Systems
The HSB Series displays can be linked to other equipment to transfer data as
follows:
• A second, repeater display which can be either CRT or LCD can be
connected via HSB (and SeaTalk) to provide radar and/or chart 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 transmited via SeaTalk and NMEA to enhance other equipment.
• Some incoming data can be converted across the communication link and re-
transmitted.
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:
Input 21 to 32 V DC
Output 13.6 V DC, isolated
Load Continuous current rating, in excess of required load
