2.1 Planning the installation
Before you start installing the Smart Heading System, read through the
information in this chapter. In particular, consider:
•
what connections you need to make to Pathfinder Plus units and/or
any other Raymarine equipment (see below)
•
where you can locate the compass – so it is away from possible
sources of magnetic interference
•
where you can locate the GyroPlus 2 unit – so it is on a vertical surface
•
how you will supply power to GyroPlus 2 unit (via SeaTalk or directly
from the boat’s distribution panel)
•
the EMC and cabling guidelines
Typical integrated systems
When installing the Smart Heading System, you need to make the
following connections:
•
Smart Heading System:
•
provide power to the GyroPlus 2 unit (see page 11)
•
connect the fluxgate compass to the GyroPlus 2 unit (see page 15)
•
Pathfinder Plus connections:
•
connect the Smart Heading System to the Pathfinder Plus using
both
NMEA and SeaTalk
•
the SeaTalk connection allows the Pathfinder Plus unit to
calibrate the Smart Heading System (see page 16)
•
the NMEA connection provides the Pathfinder Plus with fast
heading data for MARPA and radar/chart overlay (see page 16)
Adding the GyroPlus 2 unit to an autopilot
Refer to the Appendix if you need to add only the GyroPlus 2 unit to a
Raymarine autopilot (which has an existing fluxgate compass).
Connecting to a single Pathfinder Plus
If you connect the Smart Heading System to a single Pathfinder Plus
(with no other SeaTalk instruments), you will need to provide power to
the GyroPlus 2 unit direct from the distribution panel (see page 11). This
is because the Pathfinder Plus does not provide power to SeaTalk.
Note:
If you need to connect the Smart Heading System to more than one
Pathfinder Plus, see page 17.
