Setting

Description

High Speed Counter Allows you to set the rudder gain counter-correction for high speeds.

This setting applies to the vessel when operating above planing speed.

If you set this value too high, the autopilot may be overactive, attempting to constantly adjust

the heading at the slightest deviation. An overactive autopilot can cause excess wear and

tear on the drive unit

Acceleration Limiter

Allows you to limit the speed of autopilot-controlled turns.

Increase the percentage to limit the turn rate, and decrease the percentage to allow higher

turn rates.

Fine Heading

Allows you to set the lubber line (heading offset) for the autopilot.

Adjustment

NMEA Checksum

If the connected NMEA 0183 GPS unit incorrectly calculates checksums, you may still be

able to use it if you turn this setting off. When set to off, data integrity is compromised.

Reversed XTE

If the connected NMEA 0183 GPS unit sends the incorrect steering direction with the cross

track error signal, use this setting to correct the steering direction.

Navigation Gain

Allows you to adjust how aggressively the autopilot eliminates cross-track error while

following a Route-To pattern.

If this value is too high, the autopilot can oscillate back and forth across the course line over

long distances.

If this value is too low, then the autopilot may respond slowly in eliminating cross-track error.

Navigation Trim

Allows you to adjust the acceptable amount of long term cross-track error while following a

Gain

Route-To pattern. Only adjust this setting after the navigation gain has been set.

If this value is too high, the autopilot will overcompensate for cross-track error.

If this value is too low, the autopilot will allow a large long term cross-track error.

Shadow Drive

This setting lets the system know if a Shadow Drive (optional) is connected or not.

Connected

Verify Steering

This setting tells the autopilot which direction the rudder must move to turn the vessel to port

Direction

and to starboard. You can test and reverse the steering direction if necessary.

Drive Unit Class

Allows you to specify the class of your drive unit (refer to

information).

Select Other for non-Garmin drive units.

Drive Unit Voltage or

Only applicable if the Drive Unit Class has been set to "Other" or "Solenoid".

Solenoid Voltage

This setting tells the autopilot the voltage it should supply to the drive unit motor. Refer to the

documentation supplied by the manufacturer of your drive unit to determine motor voltage

specification.

An incorrect setting can cause damage to your drive unit motor.

Bypass Valve Voltage Only applicable if the Drive Unit Class has been set to "Solenoid".

This setting tells the autopilot the voltage it should supply to the solenoid bypass valve. Refer

to the documentation supplied by the manufacturer of your solenoid drive to determine the

bypass-valve-voltage specification.

An incorrect setting can cause damage to your solenoid drive.

Max. Current

Only applicable if the Drive Unit Class has been set to "Other".

Threshold

This setting tells the autopilot the maximum amount of current it can supply to the drive unit

motor.

Refer to the documentation supplied by the manufacturer of your drive unit to determine motor

current specification.

An incorrect setting can cause damage to your drive unit motor.
