4.3. Electrical Connection
The sensor requires a DC power supply of 10-30Vdc. The output is RS485, using the Modbus RTU protocol. Ensure proper wiring according to the following: Brown (DC10-30V), Black (GND), Yellow (A+), Blue (B-).
5. Operating Instructions
The weather station communicates via the RS485 (Modbus RTU protocol). Data can be read and recorded using compatible monitoring software or a dedicated portable display unit.
5.1. Data Acquisition with Portable Display
A portable display unit can be connected to the weather station to read all measured values and record data. This provides real-time monitoring capabilities on-site.

6. Maintenance
The ComWinTop Ultrasonic Weather Station is designed for minimal maintenance. It features a robust construction and ultrasonic measurement technology that generally does not require regular calibration or extensive upkeep.
- Cleaning: Periodically inspect the sensor for any accumulation of dust, dirt, or debris that might obstruct the ultrasonic transducers or other sensor elements. Clean gently with a soft, damp cloth if necessary. Avoid using abrasive materials or harsh chemicals.
- Environmental Protection: The device has an IP54 protection level, indicating resistance to dust and splashing water. While durable, avoid exposing it to extreme physical impact or prolonged submersion.
- Cable Integrity: Ensure all connecting cables are free from damage, kinks, or corrosion. Secure cables to prevent accidental disconnections or strain.
7. Troubleshooting
- No Data Output:
- Verify the DC power supply (10-30Vdc) is correctly connected and providing power.
- Check RS485 wiring (Brown: DC+, Black: GND, Yellow: A+, Blue: B-) for correct polarity and secure connections.
- Ensure the communication parameters (baud rate, parity, data bits, stop bits) in your monitoring software or configuration tool match the sensor's settings.
- Inaccurate Readings:
- Wind Direction: Confirm the 'N' mark on the sensor's upper cover is accurately aligned with true North. Obstructions near the sensor can also affect readings.
- Other Parameters: Ensure the sensor is clean and free from debris. Verify the installation location is suitable and not subject to localized anomalies (e.g., heat sources for temperature, strong local noise for noise sensor).
- Configuration Tool Issues (e.g., missing parameters):
- If the configuration tool does not display all expected parameters (e.g., pressure, temperature, illumination) or only shows a generic series (e.g., CWT-UWO instead of CWT-UWD-SDTHIAP), ensure you have the correct version of the software for your specific model. Some models may have different parameter sets, and the software might require specific model selection or a compatible version to display all features.
- Consult the official PDF user manual for detailed register addresses and parameter mappings for your exact model.
8. User Tips
- Verify Model Compatibility: When using the configuration tool, always ensure that the software version and selected device model (if applicable) are compatible with your specific weather station variant (e.g., CWT-UWD-SDTHIAP). This can prevent issues with missing parameter displays.
- Outdoor Installation: For optimal performance, install the weather station in an open area, away from buildings, trees, or other obstructions that could interfere with wind flow or sunlight.
- Regular Data Checks: Periodically check the data output to ensure consistent and accurate readings. This helps in early detection of any potential issues.
