Autopilot Package Options

Accuracy, high performance and simplicity of use are key features of the NX2 Autopilot, specifically designed for sail and power boats from 32-60 feet. Whether the need is for improved navigational accuracy, minimized fuel consumption or simply more enjoyable yachting, the NX2 Autopilot provides precision steering under all sea conditions. Factory default settings and automatic calibration allow easy operation with minimal operator input, yet user adjustable settings make it possible to fine tune it for every vessel. Use it as a standalone autopilot or connect it to the NEXUS Network to have the ultimate in Instrument/Autopilot integration.

The Autopilot system consists of five components:

NX2 Autopilot

1. Autopilot Instrument   20620044

Choose from two instrument control alternatives:

  • Fixed control via the Autopilot instrument
  • Handheld control via the Remote Control instrument

All instruments control the Autopilot in four steering modes:

  • Compass mode. Steer after a set compass heading
  • Nav mode. Steer after a waypoint set by an optional navigator
  • Wind mode. Steer after a wind angle, from the optional wind transducer and server or Wind Data display.
  • Powersteering mode. Powersteer the rudder. May be used to avoid heavy wheel effort when manoeuvring.

All instruments offer a dual display of compass heading and digital rudder angle indicator
35-deg Compass

2. 35° Compass   20640007

The extremely stable fluid damped compass provides very accurate steering information. It will guide the Autopilot when you need it the most, which is in rough weather.
NX2 Servo Unit

3. Servo (distribution) Unit   20100001

  • The course computer and interconnection terminal for all components.
  • Automated functions include compass compensation, installation setup and parameter adjustment.
  • Unique "soft start/stop" function to reduce mechanical wear, reduce power consumption and lead to a smoother handling.
  • Transmits data via the fast NEXUS Network, make the autopilot react without delay.
  • Sea state damping function.
  • Built in NMEA 0183 interface.
  • Automatic tacking function with connected wind transducer.
  • Alarms for off course, off track or watch alarms.
Dimensions: 160 x 110 x 38 mm (8.7 x 5.7 x 2.2")
Weight: 420 g (14.8 oz)
Power supply: 10-36V
Current consumption: 0.3A (at 12V) plus drive unit demand 		Enclosure: Splash proof
Cable: 8m (26ft)
Output: NMEA 0183 compass, RAI
Max. motor output drive: 15 A

Further, NEXUS offers an optional analog Rudder Angle instrument, which will be connected to the Autopilot Servo Unit.
Rudder Follower Unit

4. Rudder Follower Unit   20330008

Waterproof construction with transducer life rated to over 50 million rudder movements. The rudder linkage is self-aligning, self lubricating, corrosion resistant and easily adjustable to varying lengths. It is suitable for vessels with rudderstock up to 75 mm (3") in diameter. It is mounted near the rudder shaft and connected to the tiller arm or quadrant.

Rudder Angle Transmitter

Dimensions: 70 x 70 x 75 mm (2.7 x 2.7 x3.0")
Enclosure: Water proof
Transmitter arm: 120mm (4.7") long
Cable: 15m (50ft) 		Weight: 170 g (6 oz) (without cable and linkage arm)
Current/Power consumption: 0.5mA/2.5mW
Ball joint linkage arm: 2 arms, each 320mm (12.6") long
Rudder angle: ± 55° Resistance: 10kW

5. Drive Unit

The Drive Units are specifically designed for autopilot use to give high mechanic and hydraulic accuracy with a long lifecycle. It is designed for low internal leakage to give faster and more accurate steering with low power consumption. In addition, they offer extreme rudder precision via variable motor speed and soft start/stop. Further, the pumpsets are very quiet making them very popular with sail boat owners.

NEXUS offer two types of hydraulic drive units; the integrated linear drive or Pumpset with Linear Drive combination for vessels with mechanical steering. Other types of non hydraulic drive units may also be used (linear, rotating or relay/solenoid). The weather resistant design with its compact size allows for installation in cramped areas.
