1.1 Overview
The ST4000 Plus is a SeaTalk
Æ
compatible autopilot available for tiller
or wheel drive steering systems, which can also repeat instrument data
in a programmable selection of Data Pages.
The ST4000 Plus can share all data transmitted from other Raytheon
SeaTalk instruments:
ï Wind information from a wind instrument can be used for wind trim
(Vane) steering without the need to install a separate vane.
ï Track information, from a navigation instrument, provides waypoint
control from the autopilot.
ï Boat speed from the Speed instrument provides optimum track-
keeping performance.
The ST4000 Plus autopilot can also be used with any navigator (GPS,
Decca, Loran) transmitting NMEA 0183 data.
There are four operating modes:
Standby : Autopilot off
Auto : Autopilot engaged and locked onto a heading
Track : Autopilot maintains a track between two waypoints created
using a navigation system
Vane : Autopilot maintains a course relative to an apparent wind
angle
When the ST4000 Plus is being used to repeat instrument data, ìpop-up
pilotî pages are displayed for 5 seconds whenever a change in autopilot
control is made.
The ST4000 Plus also provides the following:
ï Automatic tack facility, which can be used in Auto and Vane modes
ï Automatic compass deviation correction
ï Northerly/Southerly heading compensation
ï Automatic heading deadband ñ seastate control
ï Waypoint advance feature
ï Setup and calibration options to suit each installation, giving
maximum performance with many types of boat, with three
calibration menus (user, intermediate and dealer)
