About this Handbook
Welcome to the handbook for the Pathfinder Smart Heading System,
consisting of the GyroPlus 2 unit and the fluxgate compass. This product
is primarily designed to provide a fast heading output on NMEA (10 Hz
at 0.1° resolution) for MARPA and radar/chart overlay features on
Raymarine Pathfinder Plus displays.
Note: For more information about MARPA and radar/chart overlay,
please refer to your Pathfinder Plus owner’s handbook.
The GyroPlus 2 unit can also be used separately to provide rate of turn
information for Raymarine course computers (see the Appendix).
This handbook contains the following chapters:

Safety notices
WARNING: Smart Heading System stabilization
Excessive turn rates during the first 10 seconds after power-up may
temporarily reduce Smart Heading System performance.
WARNING: Navigation aid
Although we have designed this product to be accurate and reliable,
many factors can affect its performance. As a result, it should only be
used as an aid to navigation and should never replace common sense
and navigational judgement. Always maintain a permanent watch
so you can respond to situations as they develop.
WARNING: Product installation
This equipment must be installed and operated in accordance with
the instructions contained in this handbook. Failure to do so could
result in poor product performance, personal injury and/or damage
to your boat.
WARNING: Electrical safety
Make sure the power supply is switched off before you make any
electrical connections.
WARNING: Calibration requirement
Before using the Smart Heading System, you MUST complete the
calibration procedures explained in Chapter 3: Calibration.
EMC conformance
All Raymarine equipment and accessories are designed to the best
industry standards for use in the recreational marine environment. The
design and manufacture of Raymarine equipment and accessories
conform to the appropriate Electromagnetic Compatibility (EMC)
standards, but correct installation is required to ensure that performance
is not compromised.
Chapter 1: Introduction 1
Chapter 1: Introduction
1.1 System overview
The Pathfinder Smart Heading System is designed to provide a fast,
accurate heading output that is suitable for the MARPA and radar/chart
overlay features on Pathfinder Plus radars and chartplotters.
It is designed to operate as part of an integrated Raymarine system,
and can be calibrated using a Raymarine Pathfinder Plus display or a
Raymarine autopilot control unit.
The heading output is provided as an HDM sentence on NMEA 0183,
updated ten times per second. It is accurate to +/-2° and has a resolution
of 0.1°.
Note: For more information, refer to the Specifications on page 32.
As shown in the following diagram, the Smart Heading System consists
of two components:
• a fluxgate compass
and
• a GyroPlus 2 unit

1.2 System components
Fluxgate compass
The fluxgate compass is the direction sensor for the Smart Heading
System. It provides the GyroPlus 2 unit with information about the boat’s
current heading.
1 Introduction
GyroPlus 2 unit
The GyroPlus 2 unit contains:
• a rate gyro sensor that measures the boat’s yaw (its rate of turn)
• a micro-processor and related circuitry to combine this rate of turn
information with the fluxgate compass signal to provide fast, accurate
heading output
• inputs and outputs to allow connections with Raymarine equipment
Note: The GyroPlus 2 unit is primarily designed to be used as part of the
Smart Heading System. However, it can also be used as a ‘stand alone’
sensor to provide rate of turn information for Raymarine course
computers. Refer to the Appendix for more information.
1.3 Using the Smart Heading System
Powering-up
Excessive turn rates during the first 10 seconds after power-up may
temporarily reduce Smart Heading System performance. For optimum
performance, keep the boat as stable as possible immediately after
power-up. This will allow the GyroPlus 2 unit to stabilize.
Radar bearing alignment
For optimum MARPA and radar/chart overlay performance, the radar
bearing alignment must be correct on the Pathfinder Plus. Refer to the
Pathfinder Plus Owner’s Handbook for more details.

WARNING: Calibration requirement
You MUST calibrate the Smart Heading System after installation
using a suitable Raymarine autopilot or Pathfinder Plus display (see
Chapter 3: Calibration).
Note: Refer to the Appendix first if you are connecting the GyroPlus 2
unit to a Raymarine autopilot.

4 Pathfinder Smart Heading System - Owner’s Handbook
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 a way fro m po ssi ble
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:
2 Installation
• 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.

Cabling guidelines
When running cables, always observe the following guidelines:
• if a cable has to be fed through the deck, use a good quality deck gland
• where cables are fed through holes, use grommets to prevent chafing
• secure long cable runs so they do not present a hazard
• wherever possible, route cables away from fluorescent lights, engines
and radio transmitting equipment, as these may cause interference
