Explanation The WaveRadar Rex2 is certified for use in hazardous areas and must be handled in strict accordance with its certification requirements. The enclosure must never be opened while powered...

Explanation The Rex2 LCD provides real-time diagnostic messages indicating operational state and fault conditions. Messages such as ELEC FAILUR, MEMRY FAILUR, and SIGNL FAILUR correspond to specifi...

Explanation Functional testing of the Rex2 can be performed by aiming the sensor at a flat, stationary surface such as a wall or deck. This approach allows verification of measurement stability, sc...

Explanation Intermittent data dropouts are most commonly caused by grounding issues, cable damage, loose connections, or intermittent power supply problems. Temporary obstructions such as vessels o...

Explanation The WaveRadar Rex2 is designed for continuous operation without the need for periodic calibration. Monthly visual inspections should include checks of the WeatherShield, antenna cleanli...

Explanation Trailing null bytes are included in the Rex2 Modbus data stream for compatibility with legacy fixed-length message parsers. These bytes do not contain measurement information and should...

Explanation Range data from the Rex2 is transmitted in units of 1/10 mm and must be correctly scaled by the receiving system. Incorrect scaling is a common source of apparent measurement faults and...

Explanation The WaveRadar Rex2 provides stable, low-latency Modbus output suitable for real-time monitoring and processing. Synchronised sampling ensures evenly spaced data points, which is critica...

Explanation The Rex2 outputs a fixed-length 17-byte HEX message over Modbus RS-485, differing from legacy WaveRadar REX units which used the proprietary TRL2 format before being converted to RS232 ...

Explanation Invalid measurements are indicated by a status word value of 0000 and occur when the Rex2 cannot reliably detect a sea-surface echo. Common causes include obstructions within the radar ...
