Configuration and setup

This determines the use of the 
autopilot computer drive 
engage port (BYPASS/ 
CLUTCH terminals). The port 
voltage is the same as the 
selected drive unit voltage. 
Drive engage has the following 
settings:  

Bypass/clutch: 

The port will activate (go high), in all autopilot steering modes, 
and typically engages a bypass valve on a hydraulic linear drive 
or a clutch on a mechanical drive when entering any of the active 
autopilot modes. This is the default setting and it allows you to 
steer the boat with the helm or wheel when in STBY or DODGE 
modes. 

Auto: 

This setting is implemented for future use. Always use the 
“Bypass/clutch” (default) setting. 

The rudder deadband function 
is adaptive and is continuously 
operative. It prevents the 
rudder from hunting and the 
adaptive function optimizes the 
deadband to the speed of the 
boat and the pressure on the 
rudder. 

If the auto-setting does not perform properly due to high inertia 
from the wheel or a loose steering gear, it can be adjusted 
manually. 
Adjust the Rudder deadband by rotating the course knob. Find 
the lowest possible value that will prevent the rudder from 
hunting. A wide deadband will cause inaccurate steering. It is 
recommended to check rudder stability and accuracy in FU-
mode when the boat is moving to get pressure on the rudder.
