Product Overview

The HM-2812 Marine Smart Instrumentation Display is an intelligent, easy-to-install digital instrument designed for clear presentation of navigation and sensor information. It supports multi-screen linkage, configurable display combinations, and data expansion. A high-definition display adapts to different light conditions, while a quick-operation keypad enables fast mode switching and brightness adjustment. Its built-in information processor receives and processes real-time data from compatible positioning, depth, and meteorological sensors.

Key Features

  • Configurable data expansion and access for user-required data.
  • Multi-screen linkage with one-key brightness and display-mode adjustment.
  • Multiple NMEA0183, NMEA2000, and AD signal interfaces through the data distributor.
  • High-definition display for clear presentation under different light conditions.
  • Built-in information processor for high-speed reception and processing of real-time data.
  • Compatibility with positioning, depth, and meteorological sensors.

Display / Operational Functions

HM-2812 rudder-status interface

Rudder Status

Presents real-time rudder-angle information so operators can monitor steering angle and rudder-blade deflection.

HM-2812 wind-data interface

Wind Data

Displays wind direction, wind speed, and wind angle information from an anemometer and wind vane.

HM-2812 speed-monitoring interface

Speed Monitoring

Connects to a Doppler velocity log to display speed relative to water, voyage data, depth, and related navigation information.

System / Data Integration

Multi-Screen System

The system supports connection of up to 8 display units through the main unit.

Sensor Integration

The main unit provides NMEA0183 receive interfaces, RS485 interfaces, and AD current acquisition interfaces for supported sensor data.

Display Connectivity

Each display unit provides USB, RS485, and LAN interfaces and operates from a DC 10–36V supply.

Quick-Operation Keypad

The separate keypad supports rapid mode switching and brightness adjustment through USB communication.
