Cable requirements

You need to consider the following points before installing the system cables:

•You need to connect the scanner to the display unit and power. The cable required will depend on the display unit and scanner type.

•All cables should be adequately clamped and protected from physical damage and exposure to heat - avoid running cables through bilges or doorways, or close to moving or hot objects.

•Acute bends must be avoided.

•Where a cable passes through an exposed bulkhead or deckhead, a watertight gland or swan neck tube should be used.

•Avoid cutting and rejoining cables. If this cannot be avoided refer to Extending the power cable on page -11.

Scanner cables

A radome scanner connected to a C or E-Series display receives power via the display unit.

Running the cable to the scanner

DO NOT pull the cable through bulkheads using a cord attached to the connector. This could damage the connections.

The cable entrance is at the rear of the scanner unit. If the unit is mounted on a hollow mast, the cable may be run inside the mast and fed though the unit’s cable entrance. Make sure that the cable does not chafe where it enters and exits the mast.

To minimize electrical interference try to avoid running radar cables near other on board electrical equipment. It is also good practice to avoid running radar cables in parallel with power cables.

Inter-unit cables

The inter-unit cable, illustrated below, is fitted with an 8-way plug and power cores (covered with a clear protective sleeve) for connecting to the scanner.

The length of the cable supplied should be sufficient to complete the cable run on most small boats. For longer runs, additional or replacement cables are available. These cables have four power cores to minimize voltage drops over the longer cable run.

Optional cable lengths available are:

•Part No. M92668 - 15 m heavy extension cable.

•Part No. M92669 - 25 m heavy replacement cable.

The maximum inter-unit cable length is limited by the minimum supply voltage, the scanner type (18” or 24 “radome), and the cable type (2 or 4 power cores).

For boats with 12 V DC power systems details of recommended cable(s) for different run lengths can be found in Extending the power cable on page -11.

Boats with 24 V DC power systems can use any combination of inter-unit cables.

Radome Scanners specifications

Raymarine Radome scanners are an essential component for maritime navigation, providing boaters and marine enthusiasts with reliable radar technology. These radar systems are known for their durability, efficiency, and advanced performance, making them a popular choice for both commercial and recreational vessels.

One of the standout features of Raymarine Radome scanners is their compact and lightweight design. This makes them particularly suitable for smaller boats where space can be a concern. Despite their size, these scanners deliver impressive range and resolution, ensuring accurate detection of other vessels, landmasses, and weather phenomena.

The technology employed in Raymarine Radome scanners includes patented CHIRP Pulse Compression, which enhances target separation and improves the ability to distinguish between close and distant targets. This leads to clearer images and more reliable data, ensuring operators can make informed decisions while navigating.

Another significant characteristic of these radomes is the advanced signal processing capabilities they offer. The radar systems can filter out clutter, such as waves and rain, to provide clear representations of objects that matter, thus reducing false alarms and enhancing situational awareness. The integration of digital signal processing (DSP) allows for adaptive gain control, which optimizes performance under varying environmental conditions.

Raymarine Radome scanners are also designed to be user-friendly. The intuitive interface LCD displays or integration with multifunction displays allow for easy operation and access to critical navigation information. Users can customize their radar settings to suit their specific needs, which enhances usability and reduces the likelihood of operator error.

Many models also feature advanced maritime safety features such as MARPA (Mini Automatic Radar Plotting Aid), which tracks moving targets and provides information on their course and speed. This technology is vital for collision avoidance and ensures a safer boating experience.

In terms of compatibility, Raymarine Radome scanners seamlessly integrate with other Raymarine systems, creating a cohesive network of navigation tools. This compatibility allows users to layer radar data with charts and other navigational information, offering a holistic view of their surroundings.

In summary, Raymarine Radome scanners are characterized by their compact design, advanced technologies, and user-friendly interface. The combination of features such as CHIRP technology, digital signal processing, and safety enhancements make them a top choice for anyone looking for precision and reliability in maritime navigation. Whether for commercial use or recreational boating, these radar systems stand out for their performance and quality.
