  • Page 7: Welcome Aboard

    The Nexus Autopilot is capable of operating either as a "Stand Alone" Autopilot, or as a "Network" application by connecting it to the Nexus Network. Many options are available, including GPS and wind transducers, Nexus Remote Control instrument and other Nexus digital and analog instruments.

  • Page 8: Components

    1.1.1 Compass transducer No Autopilot can steer better than the compass stability will allow. The Nexus compass excels in this characteristic, where the liquid dampening provides for stability even at high speeds in heavy seas. The high gimbaling angle, eliminates compass disturbance with boat heeling or rolling.

    English AUTOPILOT 1.1.5 P2, Damping of compass heading [SEA] Possible settings are [0] = Minimum to [9] = Maximum. Set by the APC routine. This setting is a combination of yaw dead-band (compass sensitivity) and compass damping. The minimum setting may only be used under calm sea conditions to avoid unnecessary rudder correction due to compass acceleration errors.

    AUTOPILOT English Damping of wind transducer. The factory default setting should be adequate. In very heavy weather or unstable wind conditions, unnecessary corrections may be minimised by increasing the setting. 6.3.5 P5, Automatic Trim Calibration [ATC] Possible settings are [0] = Minimum to [9] = Maximum. [ATC] constantly compares the course set against the course steered and slowly applies more rudder as necessary to reduce any errors to zero.
