  • Built-in multi GNSS receiver

SKU Part Number:AMEC-N321-010

Overview

The N321 is an internationally type-approved AIS AtoN type 1 with the world’s lowest power consumption. Building on the success of the Mando AIS AtoN system, the N321 offers a full range of advanced features, including the broadcasting of virtual/synthetic AtoN targets, extended alarm functions and impact detection by built-in G sensor. It can integrate lanterns and racons, and a variety of sensors directly.

 

The ruggedized enclosure is designed for reliable operation in even the most extreme environments from the equator to the Antarctic. Its small form factor ensures easy installation in even the tightest of compartments.

 

 

Optimized Connectivity and Power Consumption

The N321 incorporates 2*NMEA 0183 ports, 3*digital inputs and wake-up port to enable connectivity with lantern and sensors at minimum power consumption. N321 consumes <0.037 Ah/day under FATDMA mode to be the world's most power-saving AIS AtoN type 1.

 

 

Proven Performance and Sensitivity

Virtual/Synthetic AIS AtoN support and outstanding transmission performance with 12.5W.

 

 

Versatile Alarm Functions

The smart AIS transmitter performs self checking continuously.

 

 

Easy Installation and Configuration

The compact AIS transmitter comes with the world’s smallest form factor and an intuitive user-interface.

 

 

Built for Harsh Marine Environment

Designed for marine environment: IP68 waterproof and shock and temperature robustness.
