SmartPilot Series Commissioning Guide
1.2 The SmartPilot computer
The SmartPilot computer lies at the heart of the autopilot system. It processes
information from the sensors in the system so it can steer the boat using the drive
unit:
• it contains a microprocessor and electronic circuitry to control the drive unit
and the drive motor.
• it is the central distribution point for the autopilot system, with terminals to
take power from the boat’s distribution panel and inputs/outputs for all other
autopilot components
• it has inputs/outputs for SeaTalk and NMEA so you can connect it to Rayma-
rine and other manufacturer’s equipment.
SmartPilot types
S1G, S2G and S3G Smartpilots have a built-in yaw sensor (Gyro) which measures
the boat’s rate of turn. This information is used to enhance course keeping in
adverse weather and sailing conditions.
Non-G systems do not contain a built-in Gyro. These can be upgraded with a
dealer-fitted internal Gyro or connecting an external Gyro unit.
