2 ST4000 Plus Wheel & Tiller Autopilots Owner’s Handbook
ï Dockside rudder calibration feature, which automatically
determines the characteristics of your installation, and adjusts for
them, before you set sail
ï Raytheon CodeLock security support
1.2 Extended systems
The ST4000 Plus is compatible with other Raytheon SeaTalk
instruments. Additional fixed and hand-held SeaTalk autopilot control
units can be connected at secondary steering and control positions.
A rudder reference unit can be fitted as an optional extra, and will
improve the wheel pilotís performance. It is especially recommended if
there is significant backlash in the steering system, or optimum
performance is required from a mechanical or cable steering system.
Note: You MUST fit a rudder reference if the ST4000 Plus is installed
on a hydraulic steering system.
