NMEA 2000 cables and connectors - Mini bulk cable - 750 m (gray)

The Raymarine NG1-750 is a bulk NMEA 2000 mini cable, supplied on a 750-meter reel. Its color is gray. It is designed to establish or extend onboard data communication networks, allowing different NMEA 2000-compatible devices to communicate with each other.

The Raymarine NG1-750 cable is supplied on a reel with a length of 750 meters. Its color is gray.

An NMEA 2000 cable is used to create a digital communication network aboard a boat. It enables various marine electronic devices (GPS, fishfinders, radars, autopilots, engine instruments, etc.) to share data quickly and reliably over a single backbone.

Yes, this cable is NMEA 2000 certified. This certification ensures it has been tested and verified to meet safety criteria and to correctly implement NMEA 2000 network management and messaging.

NMEA 2000 certification means the cable has successfully passed a suite of over 100 rigorous tests. These tests ensure several essential aspects for the proper operation of the network:

Priority messaging: Ensures the most critical messages are always transmitted.Automatic addressing: Allows devices to be connected and disconnected without disrupting the network.Product information: Facilitates recognition of connected devices.Resistance to EMI and noise: Reduces electromagnetic interference and noise.Electrical isolation: Guarantees the cable will not disrupt the network and operates safely.These checks ensure the cable will function in harmony with other NMEA 2000 certified products.

NMEA 2000 cables are available in several sizes, including Micro, Mid, and Mini. The NG1-750 cable is a Mini type. Mini cables are generally more robust and have a larger diameter than Micro cables, allowing them to support longer backbone lengths and carry more current. They are particularly suited for large-scale installations or main NMEA 2000 network backbones.

Yes, NMEA 2000 cables, including the mini model such as the NG1-750, are designed to carry both communication data and electrical power to devices connected to the network.

Yes, this cable is specifically designed for marine networks. Its NMEA 2000 certification and construction are suited to the demanding conditions of the marine environment, ensuring stable and high-performance communication infrastructure.

Buying bulk cable in 750-meter lengths provides high flexibility for custom installations and large-scale networks. It allows installers to cut precise lengths as needed, reducing waste and optimizing onboard wiring layout.

Although not explicitly detailed in the provided documentation, NMEA 2000 cables certified for marine environments are typically manufactured with materials resistant to UV, saltwater, and weathering to ensure durability and reliability aboard vessels.

Installing this bulk cable requires several steps to create a functional NMEA 2000 network:

Custom cutting: Cut the cable to the exact lengths required for each segment of your network.Connecting NMEA 2000 connectors: Attach NMEA 2000 Mini-type connectors (sold separately) to the ends of the cut cables. This may require specific tools (crimping or screw-type).Respecting the topology: Connect the cables while respecting the NMEA 2000 network topology (backbone and drop lines).Network termination: Ensure the network is properly terminated with terminating resistors at both ends of the backbone.It is recommended to consult a professional or NMEA 2000 installation guides for optimal and secure installation.

This mini cable is compatible with NMEA 2000 connectors of the "mini" type, which are designed to fit its diameter. It is essential to use NMEA 2000-specific connectors and crimping or connection tools to ensure a reliable and watertight connection.

Yes, for NMEA 2000 "mini" type cables, the recommended maximum length for a backbone segment is generally 200 meters (about 656 feet) to ensure optimal signal integrity and power on the network.

Absolutely. The 750-meter bulk format is ideal for extending an existing NMEA 2000 network, allowing you to create new backbones or custom drop cables to integrate new devices or cover longer distances on board.

No, the certified NMEA 2000 cable is already designed with internal shielding to minimize electromagnetic interference (EMI) and noise. A correct installation according to NMEA 2000 standards, which includes proper grounding, is sufficient and generally does not require additional external shielding.

This cable is compatible with all NMEA 2000-certified marine electronic devices, regardless of brand (e.g., Raymarine, Garmin, Simrad, Furuno, etc.), provided they use NMEA 2000 "mini" connectors or appropriate adapters.

No, the Raymarine NG1-750 cable is specifically designed for the NMEA 2000 standard. It is not directly compatible with equipment using the NMEA 0183 protocol, which is a different communication standard. NMEA 0183 to NMEA 2000 gateways exist to interface the two types of networks.

Yes, as long as all cables and connectors are NMEA 2000 certified and comply with the standard specifications (e.g., "mini" type for this cable), they can be mixed and used on the same NMEA 2000 network, ensuring seamless interoperability.

Yes, the Raymarine NG1-750 cable is supplied on a 750-meter reel, making it easier to transport and uncoil during installation on the boat.
