Description
LCJ CV7-V-WINDYPLUG ultrasonic wind sensor
LCJ CV7-V-WINDYPLUG is a vertical-masthead CV7 ultrasonic wind-sensor configuration using LCJ’s WindyPlug interface arrangement for NMEA 2000 integration, with the listed barometric-pressure functionality. The model suffix is important because other CV7-V versions use different interfaces. F&C Marine can help confirm the NMEA 2000 network, mounting and receiving equipment before supply.
Wind and barometric measurement
The CV7 measures wind without conventional rotating cups or a mechanical vane. The WindyPlug variant provides the associated network interface and listed pressure function. Accurate wind information still depends on clean airflow and correct sensor orientation. Position the sensor where mast fittings, aerials, rigging and other structures have the least practical effect, and ensure the vertical mounting is rigid and correctly aligned.
NMEA 2000 network integration
Before connecting the WindyPlug, inspect the NMEA 2000 network rather than simply adding another drop. Confirm that the backbone is correctly terminated, appropriately powered and in good physical condition. Identify the connection point and the displays or systems that will use the wind and pressure data. Existing voltage drop, poor connectors or incorrect termination can create intermittent information that may be mistaken for a sensor fault.
Mounting and cable route
Plan the mast cable route and network connection before installing the sensor. Protect the cable from chafe, sharp edges, crushing and water ingress, particularly at mast or deck penetrations. Inspect existing brackets and cable glands before reuse. If the CV7-V-WINDYPLUG is replacing older equipment, label and photograph connections before removal. A hidden cable fault can remain after a new masthead sensor is fitted, so the whole route should be considered.
Commissioning wind and network data
After fitting, verify wind speed, wind direction and the expected barometric information on the NMEA 2000 displays. Check the physical orientation of the sensor and compare values across receiving devices. If one display is missing information while others are correct, investigate that device and the network path before treating the sensor as faulty. Check network power under operating conditions and confirm there are no relevant alarms before handover.
Maintenance and troubleshooting
Routine inspection should include the sensor body, vertical mounting, mast cable, WindyPlug and accessible NMEA 2000 connectors. Look for contamination, physical damage, corrosion or moisture. If data becomes unstable, verify network voltage, termination and connections as well as the sensor. A healthy wind instrument on a weak or incorrectly constructed NMEA 2000 network can behave intermittently, so the network is part of the fault-finding process.
Documentation and related guidance
For manufacturer information, see LCJ Capteurs products and LCJ support downloads. Use current LCJ documentation as the final reference for WindyPlug, mounting and configuration. F&C Marine’s ultrasonic wind-sensor guide and Marine Electronics Knowledge Base provide related guidance.

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