Explanation:
Integrating the WaveRadar Rex into WVC requires correct serial‑communication parameters. The Rex operates at a fixed 4800-8-N-1‑baud rate with predetermined parity and data bits, meaning COM-port configuration must exactly match the sensor’s output Incorrect settings result in dropped messages, corrupted frames, or failure to open the port altogether.
The protocol is 2 wire RS 485, enabling a range of ~1200m. Mechanically, the WaveRadar Rex must maintain clear vertical sight to the water surface. Obstructions, platform overhangs, flanges, and railings introduce reflections that degrade signal quality. The sensor must be mounted on a rigid, vibration-resistant structure. Excessive hull vibration may produce false high‑frequency noise interpreted as wave patterns. Troubleshooting starts with verifying COM-port availability. If WVC reports “port unavailable,” inspect PCI‑serial expansion cards: several default to incompatible buffer modes that prevent the Rex stream from being read. Switching these cards to “Normal” mode resolves most connectivity issues (Ref: Comm Port Notes). When performance counters show checksum failures, inspect connector corrosion, cable shielding, or ground loops. For skipped bytes, unstable power supplies or damaged conductors are common root causes. If wave heights appear artificially low or high, check radar-to-water height calibration and mounting angle. Even minor angular deviations introduce measurable bias. When the radar intermittently freezes, confirm that no third‑party applications (terminal readers, NMEA tools, logging utilities) are simultaneously accessing the same COM port. A stable installation includes proper grounding, validated wiring, shielded twisted-pair cabling, and uninterrupted power. WVC’s debug logs and performance counters are useful for diagnosing early‑stage communication issues.
Additional notes:
Verify wiring, grounding, and igidity of installation to maintain data integrity.
