Combined with full PID intelligence, auto rudder stability, Autotrim (APH), integral audible/visual Alarm functions with Reset, the NT777 is equipped for precision performance and reliability.
The Autopilot Display may be presented in positive or negative mode as preferred (Set Up Menu Installation Selectable).
Automatic display graphic change occurs when Track Steering Mode is selected and includes regular performance and source data updates.
  In addition to Track data, the NT777 will also accept NMEA heading data directly from GPS compass systems etc.

When multi Heading Inputs are employed (NMEA + Mag sensor coil) the priority source is installation programmable with automatic changeover in the event of primary source failure.

Suitable for console or bracket mounting, the NT777 Control Unit can be externally located and the overall system is normally supplied complete with Heading Sensor Coil (HSC2) and Rudder Reference Unit (NT920RRU) for installation to solenoid hydraulic systems (11-40Vdc/5A max).

High voltage solenoids (110/220Vac/dc) can also be accommodated via the inclusion of an optional Universal Relay Box.

The NT777 Autopilot system can also be used with alternative Distribution Units to provide ± 10Vdc or 4-20mA outputs required to interface with analogue steering machines.
