Extreme-Duty Confidence for Marine & Autonomous Systems

Airmar NMEA0183 & NMEA2000 CANBUS WEATHERSTATION, RS232, NO RH, IPX7 - WS-300WX-RS232-IPX7

Part #WS-300WX-RS232-IPX7

MFG #300WX-7-232-01

Note: Cables sold separately unless otherwise specified

When equipment lives offshore, on deck, or in dusty environments, exposure is constant and failure is expensive.

The 300WX-IP67 delivers the same next-generation intelligence as the 300WX, but in a fully sealed, IP67-rated housing engineered for continuous exposure to water, dust, vibration, and harsh marine conditions.

This is the model trusted for offshore platforms, buoys, unmanned surface vehicles, commercial workboats, and long-duration autonomous deployments. It’s designed not just to perform — but to endure.

True Wind. True Awareness. Even at Sea.

On moving vessels, apparent wind alone is misleading. The 300WX-IP67 continuously calculates Dynamic True wind by integrating GNSS speed data with stabilized heading and motion data to cancel out apparent wind and deliver the True wind speed and direction. That clarity improves navigation decisions, supports autonomous control systems, and enhances vessel performance optimization.

Built for Harsh Reality

The IP67 enclosure protects against water and dust intrusion, while the proven, rugged housing durability enhances long-term reliability in exposed environments. The 300WX-IP67 removes worry from the equation. It simply continues working — through spray, salt, vibration, and long deployments.

Seamless Connectivity Without Complexity

Like its counterpart, the IP67 model integrates easily into marine and industrial networks, including NMEA 2000®, NMEA 0183, J1939, and ISOBUS systems. Bluetooth** connectivity with Airmar's CAST™ enables remote configuration and firmware updates without removing it from its installed location — especially valuable for mast-mounted or difficult-to-access installations.

Features

  • Ultrasonic measurement of apparent and Dynamic true wind speed and direction
  • Barometric pressure
  • Air temperature and wind chill
  • Relative humidity (field serviceable option)
  • Calculated dew point and heat index
  • GNSS position, speed over ground, and course over ground
  • Three-axis, solid-state compass with dynamic stabilization
  • Three-axis rate gyro supplies rate-of–turn data
  • Three-axis accelerometer for best-in-class pitch and roll information
  • Housing IP67 rated for dust/water-ingress protection
  • Data output via a single cable (various lengths available)
    • NMEA 0183/ASCII serial data protocol over RS-232 interface
    • NMEA 2000 protocol over CAN
    • J1939
    • ISOBUS

New Features of the 300WX WeatherStation Instruments:

  • Enhanced wind speed accuracy: 1.5 knots RMS at 20 knots
  • Bluetooth® wireless connectivity for use with Airmar’s CAST app to view data, configure sensors, and perform firmware updates
  • Added communication protocols: J1939 and ISOBUS
  • Automatic baud rate detection for J1939 and ISOBUS (250 kbps / 500 kbps)
