Clutch Voltage
Only applicable if the Drive Unit Class has been set to “Other”.
This setting tells the autopilot the voltage it should supply to the drive unit clutch. Refer to the
documentation supplied by the manufacturer of your drive unit to determine clutch voltage
specification.
An incorrect setting can cause damage to your drive unit clutch.

Generic Drive Unit
Tune
Only applicable if the Drive Unit Class has been set to “Other”.
This initiates an automatic tuning procedure which determines an appropriate gain value for
the installed drive unit.
While performing this tune the autopilot will temporarily take control of the rudder.

Advanced Drive Unit Tuning
Speed Tune
Only applicable if the Drive Unit Class has been set to “Other”.
Allows you to adjusts how aggressively the drive unit responds to a given input (
If this number is too high, the drive unit will overshoot and oscillate around its target position.
If this number is too low, the drive unit will respond slowly to a commanded change in position.

Advanced Drive Unit Tuning
Error Tolerance Tune Only applicable if the Drive Unit Class has been set to “Other”.
Allows you adjusts the amount of acceptable rudder position error (
If this number is too high, a large amount of rudder position error will be allowed, and could
negatively affect the course during heading hold.
If the number is too low, the drive unit will attempt to eliminate small errors, causing excess
power consumption.
Steering System Setup >
Rudder Sensor Setup
Max Port Angle
Allows you to enter the angle at which your rudder turns furthest port.
Steering System Setup >
Rudder Sensor Setup
Max Starboard Angle Allows you to enter the angle at which your rudder turns furthest starboard.
Steering System Setup >
Rudder Sensor Setup
Calibrate Rudder
Sensor
Initiates a procedure which establishes the maximum range of movement of the rudder and
calibrates the rudder sensor.
If an error appears during the calibration, the rudder feedback sensor has likely reached its
limit. Make sure the feedback sensor has been correctly installed. If the problem persists,
bypass this error by moving the rudder to the farthest position that does not report an error.
Steering System Setup >
Rudder Sensor Setup
Calibrate Rudder
Center
Initiates a procedure which establishes the center position of the rudder.
Use this calibration if the on-screen rudder position indicator does not match the true rudder
center on your boat.
NOTE:
Advanced configuration settings are available when using Dealer Mode (
). Other settings are available during normal operation of
the GHP 12. See the configuration section of the
GHC 10 Owner’s Manual
for more information.
