1.2 Extended systems

The ST4000+ is compatible with all other SeaTalk instruments. 

You can connect it to additional fixed or handheld SeaTalk autopilot 

control units located at secondary steering and control positions 

(see page 52).

You can also use the ST4000+ autopilot with any 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-defined selection of data pages. When you are using the 

ST4000+ to repeat instrument data, it shows a ‘pop-up’ pilot page for 

5 seconds whenever you make a change in autopilot control.

The ST4000+ can share all data transmitted from SeaTalk 

instruments:

•

it can use wind information from a SeaTalk wind instrument for 

wind trim steering in Wind Vane mode without the need for a 

separate vane

•

it can use track information from a SeaTalk navigation instrument 

to provide waypoint control in Track mode

•

it can use boat speed from a SeaTalk speed instrument to optimize 

track-keeping performance

Rudder position sensor (wheel drives only)

On wheel drive systems you can fit a rudder position sensor to 

improve the wheel pilot’s performance (see page 81). This is 

particularly advisable if your boat’s steering system has significant 

backlash, or you require optimum performance from a mechanical or 

cable steering system. By using the information from the rudder angle 

sensor, the ST4000+ will also be able to show the true rudder angle in 

Standby and Auto modes.

Note: You MUST add a rudder position sensor if fitting the ST4000+ 

to a hydraulic steering system.
