Raymarine Combined Pathfinder Radar Integrated Systems, DC-DC Converter for External Equipment

Chapter 8: Installation 8-21

8.8 Integrated Systems

The hsb2 series displays can be linked to other equipment to transfer data as follows:

•Additional displays, either CRT or LCD, can be connected via hsb2 (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:

Table 8-2: DC-DC Converter for External Equipment

Input	21 to 32 V DC
Output	13.6 V DC, isolated
Load	Continuous current rating, in excess of required load

hsb2™ (High Speed Bus) Multiple Display Systems

You can connect several hsb2 displays; the number is dependent on cable length - see hsb2 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.
