Introduction
The Furuno 200WX Ultrasonic Weather Station is an advanced, all-in-one sensor designed to provide essential weather readings with high precision and accuracy. It detects instantaneous changes in weather conditions and operates continuously, even in adverse environments. This station measures apparent and true wind speed and direction, air temperature, and wind chill temperature. It also integrates a 3-Axis solid-state compass and a 3-Axis Rate Gyro for superior compass and pitch/roll accuracy. The 200WX supports both CanBUS/NMEA2000 and NMEA 0183 connectivity, allowing direct connection to compatible marine navigation systems like NavNet TZtouch/NavNet 3D DRS Radar sensors. Power is supplied via the NMEA 2000 bus, facilitating flexible installation. Its UV-stabilized, compact, and fully waterproof housing is resistant to chemicals and sunlight, ensuring durability.

Setup
This section details the initial setup of your Furuno 200WX Ultrasonic Weather Station.
Unpacking and Inspection
- Carefully remove all components from the packaging.
- Verify that all included components are present:
- Furuno 200WX Ultrasonic Weather Station unit
- Mounting Hardware
- Connection Cable
- Inspect all components for any signs of damage. Contact customer support if any damage is found.
Mounting the Weather Station
The 200WX features a standard 1-inch mount, accommodating existing mounted hardware. Ensure the mounting location provides an unobstructed view of the sky for accurate readings.
- Select a suitable mounting location, free from obstructions that could interfere with wind or precipitation measurements.
- Secure the mounting hardware according to the provided instructions.
- Attach the 200WX unit to the mounted hardware, ensuring it is firmly in place.
Electrical Connection
The 200WX supports both CanBUS/NMEA2000 and NMEA 0183. Power is supplied from an NMEA 2000 bus.
- Connect the provided cable to the NMEA 2000 port on the 200WX unit.
- Connect the other end of the cable to your NMEA 2000 bus or compatible NavNet TZtouch/NavNet 3D DRS Radar sensor.
- Ensure all connections are secure and waterproof.
Operating Instructions
The Furuno 200WX Ultrasonic Weather Station provides continuous weather readings with no moving parts. Data is converted and distributed throughout the NavNet TZtouch/NavNet 3D Ethernet network.
Data Acquisition
- The unit automatically measures and transmits:
- Apparent and True Wind Speed and Direction
- Air Temperature
- Wind Chill Temperature
- Barometric Pressure
- The integrated 3-Axis solid-state compass and 3-Axis Rate Gyro provide accurate compass and pitch/roll data.
Interfacing with Display Units
Connect your display unit (e.g., NavNet TZtouch/NavNet 3D) to the NMEA 2000 network to view the weather data. Refer to your display unit's manual for specific instructions on configuring data displays.
The system is designed for continuous operation, even in adverse weather conditions.
Maintenance
The Furuno 200WX Ultrasonic Weather Station is designed for minimal maintenance due to its lack of moving parts.
Routine Cleaning
- Periodically inspect the unit for any accumulation of dirt, salt, or debris.
- Clean the exterior of the unit with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Ensure the ultrasonic transducers (located on the top of the unit) are clear of obstructions.
Environmental Considerations
The UV-stabilized, compact housing is fully waterproof and resistant to chemicals and sunlight, ensuring long-term durability in marine environments.
Troubleshooting
This section provides solutions to common issues you may encounter with your 200WX Weather Station.
No Data Displayed
- Check Power: Ensure the NMEA 2000 bus is powered and the 200WX unit is receiving power.
- Cable Connections: Verify that the NMEA 2000 cable is securely connected to both the 200WX and the network.
- Network Configuration: Confirm that your display unit is correctly configured to receive data from the NMEA 2000 network. Refer to your display unit's manual.
Inaccurate Wind Readings
- Obstructions: Check for any physical obstructions near the unit that could be interfering with wind flow (e.g., mast, rigging, other sensors).
- Mounting Location: Ensure the unit is mounted in a location with clear, undisturbed airflow.
- Sensor Cleanliness: Clean the ultrasonic transducers as described in the Maintenance section.
Incorrect Compass/Pitch/Roll Data
- Calibration: If available, perform a compass calibration procedure on your connected display unit or through the 200WX configuration.
- Magnetic Interference: Ensure the unit is not mounted too close to strong magnetic fields (e.g., large metal objects, electrical cables).
