Description
LCJ CV7-WINDYPLUG ultrasonic wind sensor
LCJ CV7-WINDYPLUG is a short-arm masthead ultrasonic wind-sensor configuration supplied with a 25m cable and LCJ WindyPlug interface for NMEA 2000 integration, with barometric-pressure functionality in the listed configuration. The model suffix is important because other CV7 versions use different interfaces. F&C Marine can help confirm the network and masthead installation before supply.
Wind and barometric measurement
The CV7 measures wind electronically without conventional rotating cups or a vane. The WindyPlug configuration also provides the associated interface for the listed NMEA 2000 and barometric arrangement. Wind accuracy still depends on clear airflow and correct alignment. Position the sensor where mast structures, aerials and rigging have the least practical influence and follow LCJ installation guidance for orientation.
NMEA 2000 integration
Before connecting the system, inspect the vessel’s NMEA 2000 network rather than simply adding another device. A correctly built backbone requires proper termination, a suitable power connection and drop-cable arrangement. Identify where the WindyPlug will connect and confirm that the network is healthy. Existing voltage drop, incorrect termination or damaged connectors can create intermittent wind data that may incorrectly be blamed on the sensor. Record the network connection point for future service.
Masthead mounting and cable route
Plan the 25m mast cable route from the sensor to the interface and network. Protect it from chafe, sharp edges and crushing, and inspect deck or mast penetrations for water ingress. If an older sensor is being replaced, inspect the mount and cable rather than automatically reusing them. A damaged cable hidden inside the mast can remain a fault after a new sensor is installed, so continuity and physical condition should be considered during the refit.
Commissioning the wind system
After installation, verify wind speed, direction and the expected barometric information on the NMEA 2000 displays that use the data. Check the sensor orientation and compare values across receiving devices. If only one display is missing information, investigate the network and that device’s configuration before treating the masthead sensor as faulty. Check network voltage under operating conditions and resolve any alarms before handover.
Maintenance and troubleshooting
Routine inspection should include the sensor body, mounting, cable, WindyPlug and accessible NMEA 2000 connectors. Look for contamination, physical damage, corrosion or moisture. If wind data becomes unstable, verify network power and termination as well as the sensor. A sound sensor connected to a weak or incorrectly constructed network can behave intermittently. Keeping the fitted model and network layout in the vessel records makes later troubleshooting considerably easier.
Documentation and related guidance
See LCJ Capteurs products and LCJ support downloads. Use the current LCJ documentation as the final reference for WindyPlug and sensor configuration. F&C Marine also provides an ultrasonic wind-sensor guide and a Marine Electronics Knowledge Base with NMEA and installation guidance.

Before ordering LCJ CV7-WINDYPLUG
Send the vessel type, existing wind equipment, photographs of the masthead and NMEA 2000 network, cable-route details and the make and model of the displays that need wind data. If the project follows a fault, include the symptoms and tests already completed. F&C Marine can then help confirm whether LCJ CV7-WINDYPLUG is the correct version and identify any network, mounting or installation work needed.
