Computer cabling: the backbone of your marine electronics

The reliability of your onboard electronic system depends largely on the quality of its cabling. A well-designed network ensures optimal data transmission between your instruments, from GPS and radar to autopilot. Drawing on its experience in offshore racing, Skysat offers a carefully curated selection of cables, connectors, and accessories to guarantee the robustness and performance of your installation.

Here you'll find everything you need to build a high-performance NMEA 2000 network, interconnect your SeaTalk NG instruments, or establish robust Ethernet links. Our approach is simple: to provide you with proven, documented solutions tailored to the demands of the marine environment.

The foundations of a reliable NMEA 2000 network

NMEA 2000 has become the standard for interconnecting onboard electronic instruments. Its robustness and ability to transmit large amounts of data make it an ideal choice for complex systems. High-quality NMEA 2000 cabling is essential to ensure smooth and reliable communication between your devices.

• NMEA 2000 backbone cables: Choose a quality cable that is UV and weather resistant, taking into account the total length of your network.
• NMEA 2000 T connectors: Ensure compatibility with your devices and prioritize waterproof connectors to avoid corrosion.
• NMEA 2000 drop cables: Select the appropriate length to connect your instruments to the backbone, avoiding excessive lengths that may disrupt the signal.
• NMEA 2000 terminations: Essential at the ends of the backbone to avoid signal reflections and ensure optimal communication.

SeaTalk NG connectivity: simplicity and performance

SeaTalk NG (Next Generation) is Raymarine's proprietary communication protocol, designed to simplify the interconnection of their instruments. Although based on NMEA 2000, it uses specific connectors and requires an understanding of its architecture for successful integration.

• SeaTalk NG backbone cables: Identical to NMEA 2000 cables, but with specific Raymarine connectors.
• SeaTalk NG connectors: Ensure compatibility with your Raymarine instruments and use the appropriate connectors (spurs, terminators).
• SeaTalk NG Junction Blocks: Useful for creating additional connection points and organizing your cabling.
• SeaTalk NG to NMEA 2000 Adapters: Enable interconnection with NMEA 2000 compatible devices from other brands. Check compatibility and limitations.

Marine Ethernet networks: high-speed data

For applications requiring high bandwidth, such as radar or video data transmission, a marine Ethernet network is essential. The choice of cables and connectors must take into account the constraints of the marine environment (humidity, vibration, interference).

• Marine-grade Cat5e or Cat6 Ethernet cables: Opt for shielded cables that are resistant to UV and hydrocarbons.
• Waterproof RJ45 connectors: Essential to guarantee a reliable and durable connection, even in difficult conditions.
• Marine Ethernet switches: Choose a model suited to your network needs, with a sufficient number of ports and redundant power supply if necessary.
• Marine Wi-Fi access points: Allow the creation of a wireless network on board, to connect tablets, smartphones and computers.

💡 Skysat's advice

Before you begin your wiring, create a precise diagram of your network, taking into account the position of each instrument and the length of the cables required. Always leave a safety margin to facilitate future modifications.
