Cablu SeaTalk 20m

This cable is designed to reliably interconnect Raymarine instruments and displays compatible with a SeaTalk network. It enables data transmission between different navigation devices from the brand, such as instruments, autopilots, and multifunction displays from previous generations.

The SeaTalk Raymarine D288 cable has a length of 20 meters. This length is ideal for installations requiring routing over significant distances aboard medium to large vessels.

No, the SeaTalk D288 cable is not directly compatible with SeaTalkNG systems. The SeaTalk network is a distinct proprietary data bus, while SeaTalkNG is based on the NMEA 2000 standard. Specific converters (such as the SeaTalk1 to SeaTalkNG) are required to enable communication between the two types of networks.

This cable is compatible with Raymarine equipment that uses the original SeaTalk communication protocol. This typically includes navigation instruments, autopilots, and some multifunction displays from earlier generations of the brand.

No, the SeaTalk cable is specifically designed for Raymarine's proprietary SeaTalk network. It is not compatible with the NMEA 0183 protocol, which uses a different data format and connections.

You can check the documentation for your Raymarine equipment. SeaTalk devices are usually equipped with specific 3-pin connectors (sometimes black or grey) and are clearly marked as part of the SeaTalk network.

Yes, as a Raymarine component, this cable is designed for use in a marine environment. It is manufactured to withstand typical conditions encountered at sea, ensuring reliable connectivity for your marine electronics.

It is not recommended to cut or modify the length of pre-assembled SeaTalk cables. This could compromise signal integrity and the reliability of the connection. It is better to use cables of the appropriate length or extensions designed for this purpose.

During installation, it is important to:

Route the cable to avoid electromagnetic interference with other equipment.Protect the cable from chafing and pinch points.Ensure watertight and secure connections to devices to prevent water ingress.Respect minimum bend radii to avoid damaging internal conductors.

The SeaTalk network carries both data and 12 V power to small instruments. The D288 cable can therefore supply power to compatible devices connected to the SeaTalk bus, within the bus’s specifications.

SeaTalk connectors are generally plug-and-play and do not require specific tools for connecting to devices. However, for routing and securing the cable on board, basic tools such as cable ties or cable glands may be useful.

SeaTalk is a proprietary communication protocol developed by Raymarine for its earlier-generation navigation equipment. NMEA 2000 is an open international standard (based on CAN bus) enabling interoperability between marine equipment from different brands. SeaTalkNG is Raymarine's implementation of NMEA 2000.

It is technically possible to connect multiple SeaTalk cables using junctions or distribution boxes. However, for very long runs, you should consider potential signal degradation and voltage drop. It is generally better to use the most appropriate cable length to minimize connection points.

Marine communication cables of high quality, such as those from Raymarine, are typically designed with shielding to minimize electromagnetic interference and ensure stable data transmission in the complex electrical environment of a boat.

The connectors on Raymarine's original SeaTalk cables are often black or gray and have a specific 3-pin shape, distinct from NMEA 2000 connectors (often blue or black and 5-pin).

This cable is primarily intended for extending or maintaining existing Raymarine systems that use the SeaTalk protocol. New Raymarine systems generally favor SeaTalkNG (NMEA 2000) for better interoperability and higher data rates.

The SeaTalk network typically operates on a 12-volt DC supply voltage, transmitted via this cable in addition to data. This power supply is used by the instruments connected to the network.

Yes, there are limits to the number of devices and the total length of the SeaTalk network due to electrical load and signal degradation. For complex installations, it is recommended to consult Raymarine's installation manuals for exact specifications and best practices.

Yes, like all original Raymarine products, this 20m SeaTalk cable comes with the manufacturer's standard warranty. This warranty typically covers manufacturing and material defects under normal usage conditions.

The cable is designed for marine use and can be routed outdoors on a boat. However, to maximize its lifespan, it is always preferable to protect it from direct and prolonged exposure to intense UV and abrasion where possible, by running it inside structures or under protective covers.
