Radar line-of-sight compensator for M1815, DRS 4DL+ and 4DNXT radars on rotating mast.

The FURUNO RO-CMT1 heading compensator is designed for radar installations on rotating masts. Its primary function is to ensure precise alignment of the radar image with the ship's longitudinal axis, regardless of the mast's angle. It maintains a consistent heading reference, providing reliable situational awareness around the vessel.

Using a compensator is essential on a rotating mast because without it, the radar's heading line orientation would vary with the mast angle. This would result in incorrect readings of target positions relative to the vessel's axis. The RO-CMT1 corrects this deviation to ensure the heading line remains aligned with the bow at all times, providing accurate and consistent radar information.

The RO-CMT1 compensator improves accuracy by receiving a signal from a mast angle sensor. It uses this information to dynamically adjust the heading line display on the radar screen. Thus, even if the mast rotates, the heading line remains fixed relative to the vessel's axis, enabling correct interpretation of radar echoes and safer navigation.

The 'heading line' is a virtual line displayed on the radar screen that represents the ship's longitudinal axis, i.e., the direction the boat is pointing. It is crucial for determining the relative position of targets with respect to the bow and for anticipating trajectories.

The RO-CMT1 compensator is an active device. It requires a power supply (12V or 24V) and an analog input signal (0-5 Volts) from a mast angle sensor to operate and perform compensation.

A stable heading line offers several benefits for navigation, including:

Increased safety: Enables quick and accurate assessment of collision risks.
Navigation precision: Facilitates course keeping and radar information interpretation.
Ease of use: Reduces operator fatigue by eliminating the need to visually compensate for mast rotation.
Data reliability: Ensures radar data is always displayed consistently with the vessel’s actual heading.

The RO-CMT1 is a key component that integrates into a larger radar system. It is not standalone and must be connected to a compatible Furuno radar and a mast angle sensor to function properly and provide its compensation function.

The RO-CMT1 compensator is specifically designed for vessels equipped with a rotating mast. It is essential for these installations to ensure that the radar image remains aligned with the ship's axis, regardless of the mast's angle.

The RO-CMT1 compensator is compatible with several Furuno radar models, including the M1815, DRS4DL+, DRS2D-NXT, DRS4D-NXT, and DRS4D X-CLASS series.

The FURUNO RO-CMT1 compensator is specifically designed to integrate with the following Furuno radar systems (M1815, DRS4DL+, DRS2D-NXT, DRS4D-NXT and DRS4D X-CLASS). Compatibility with radars from other brands is not specified and cannot be guaranteed.

The RO-CMT1 autopilot compensator requires a connection to a mast angle sensor that provides a 0-5 Volt analog input signal. The FAP-6112 is listed as a compatible sensor example.

The FAP-6112 is mentioned as an example of mast angle sensor compatible with the system. The essential criterion is that the sensor provides a 0-5 Volt analog input signal to the RO-CMT1 compensator. Other sensors meeting this specification may also be compatible, but the FAP-6112 is the one explicitly cited.

The RO-CMT1 compensator is designed to be powered by the radar or mast base and accepts 12V or 24V voltage.

Yes, the RO-CMT1 compensator is designed for easy integration into NMEA2000 networks. The required connection cable between the DRS radar and the compensator is described as similar to CanBus-NMEA2000 cables, equipped with Micro5C female connectors, indicating compatibility with this type of network.

The RO-CMT1 compensator requires a 0–5 V analog input signal from the mast angle sensor to function correctly.

No, the connection cable between the DRS radar and the RO-CMT1 compensator is not included with the product. It must be purchased separately.

The cable required to connect the compensator to the DRS radar is described as being similar to CanBus-NMEA2000 cables. It must be equipped with Micro5C female connectors for correct integration.

The RO-CMT1 compensator is powered by the radar itself or by the mast base. It is compatible with 12V or 24V electrical systems.

No, the mast angle sensor, such as the FAP-6112 mentioned as an example, is not included with the RO-CMT1 compensator. It is a separate component that must be purchased separately.

To integrate the RO-CMT1 into the existing system, several connections are required:

A 12V or 24V power supply (provided by the radar or mast base). A connection to a mast angle sensor providing a 0-5 Volt analog signal. A connection to the DRS radar via a dedicated cable (not included) similar to CanBus-NMEA2000 cables with Micro5C female connectors.
