Detailed description
Detailed description
The Navico NAC-1 autopilot computer is the central electronic component of the Outboard Pilot and Drive Pilot autopilot systems. It integrates the steering computer and control electronics for the engine and clutch of the drive unit. Designed for boats up to 9 meters (30 feet), it provides autopilot solutions for hydraulic and cable steering systems.
Connectivity and Integration
The NAC-1 provides NMEA 2000® connectivity for integration with heading sensors, rudder angle sensors, and multifunction displays. It features a Micro-C NMEA 2000 port and supports NMEA 0183 sentences (HDG, HDT, HDM, GGA, GLL, RMC, VTG) with automatic baud rate detection (4800, 9600, 19200 or 38400). An Ethernet port (100 Mbit RJ45 with supplied 5-pin yellow adapter) is also included. The system is compatible with Lowrance or Simrad displays for an integrated autopilot experience.
Technical Features and Installation
With a power supply voltage of 9-16VDC and a 12VDC drive output (8A continuous, 16A peak), the NAC-1 is designed to control the reversible PUMP-1 hydraulic pump or the HELM-1 drive unit. It integrates Continuum™ steering technology for reliable autopilot performance and the Virtual Rudder Feedback (VRF) function, which eliminates the need for a separate rudder angle sensor on planing outboard and sterndrive boats, simplifying installation. Plug-and-play connectors facilitate wiring. The device also supports 0-5V and RF25 rudder angle sensors. It has an IPx5 water resistance rating and operates within a temperature range of -25°C to +55°C. The NAC-1 dimensions are 204 x 190 x 57 mm and it weighs 0.6 kg (1.3 lbs).
Steering Modes and Control
The NAC-1 enables steering to a heading, route, or waypoint, and supports automatic turning patterns for navigation. An Auto/Standby activation via push button is available for quick use. For a complete system, the NAC-1 requires a drive unit, a heading sensor (such as the Precision-9 compass), an NMEA 2000® network, and a compatible autopilot controller or multifunction display.
