1.1 Features
The Raymarine ST4000 Plus(ST4000+)is a SeaTalk®compatible
autopilot available in versions suitable for boats with either tiller or
wheel steering systems. This autopilot system willsteer your boat to
a heading automatically, accurately and reliably.
The ST4000+ hasfour mainoperating modes:
1. Standby: autopilot off (see page 7)
2. Auto:autopilotengaged and locked ontoaheading(seepage 6)
3. Track: autopilot engagedand maintaining a track between two
waypoints createdusing a navigationsystem (seepage 20)
4. Wind Vane:autopilotengagedandmaintainingacourserelative

1 Introduction
1.2 Extended systems
The ST4000+ is compatible with all other SeaTalk instruments.
You canconnect it toadditional fixedor handheld SeaTalk autopilot
control units located at secondary steeringand control positions
(see page 52).
You can alsouse the ST4000+ autopilot withany navigator
(GPS, Decca, Loran)or wind instrument that transmits data in the
internationally-accepted National Marine Electronics Association
(NMEA)0183 format.
The ST4000+ can display SeaTalk and NMEA instrument data in a
user-definedselection of datapages.Whenyou areusingthe
ST4000+torepeatinstrumentdata,itshowsa‘pop-up’pilotpagefor
5 seconds whenever you make a change in autopilot control.
The ST4000+can share alldata transmittedfrom SeaTalk
instruments:
•it can usewind information from aSeaTalk windinstrument for
wind trim steering in Wind Vane mode without the need for a
separatevane
•itcanusetrackinformationfromaSeaTalknavigationinstrument
toprovide waypointcontrolin Trackmode
•itcanuseboatspeedfromaSeaTalkspeedinstrumenttooptimize

Rudder position sensor (wheel drives only)
On wheel drive systemsyou can fit a rudderposition sensor to
improve the wheel pilot’s performance (see page 81).Thisis
particularly advisable if yourboat’s steeringsystem hassignificant
backlash,oryourequireoptimumperformancefromamechanicalor

2.1 Using the control unit
Key functions
•The autopilot always powersup in Standby mode.
•You control the autopilot by pressing the buttons on the control
unit. The control unit confirms each button presswith a short
beep.
•You access the main functionsby pressinga single key:
•for example, whenthe autopilot is operating youcan make
coursechangesusingthe -1,+1,-10 and+10 keys
•To access other functionsyou need to press twokeys together:
•for example, whenthe autopilot is operating youmake an
AutoTack to port by pressing the -1 and-10 keystogether
•You can return to manual steering atany time by pressing
standby and disengaging theautopilot (see page 7).
