SeaTalk NG 1 meter Branch Cable

This cable, called a spur cable, connects an individual device, such as an instrument display, sensor, or GPS antenna, to the main backbone of your Raymarine SeaTalk NG network.

This SeaTalk NG branch cable, part number A06039, is exactly 1 metre long.

The SeaTalk NG network is based on the NMEA 2000 protocol, so the data is compatible. However, the physical connectors are proprietary to Raymarine. To connect this cable to a device or NMEA 2000 network with standard connectors (DeviceNet), you will need a specific adapter cable.

This branch cable must be connected to an open port on a T-connector (T-piece) or a 5-way junction block that is itself installed on the backbone of your SeaTalk NG network. The other end connects directly to your instrument or sensor.

The difference lies in their function and color:

Spur cables (white connectors), like this one, connect an individual device to the backbone. Backbone cables (blue connectors) form the network's backbone, linking the various connection points (T-pieces) together. Raymarine designed this color distinction to prevent wiring errors.

Yes, A06039 branch cable provides both data transfer and electrical power to the connected device directly from the SeaTalk NG backbone.

You can connect other brands’ equipment certified for NMEA 2000 to a SeaTalk NG network. However, you will need an adapter cable to convert from the proprietary SeaTalk NG connector to the standard NMEA 2000 (DeviceNet) connector of the other device.

No, it is strongly discouraged to cut or modify SeaTalk NG cables. This would compromise waterproofing, shielding, and the reliability of connections, potentially causing malfunctions across your entire navigation network.

No, this cable is not directly compatible with SeaTalk1 or SeaTalk2 networks. To integrate devices from these older generations into a SeaTalk NG network, you must use a Raymarine-specific conversion gateway.

Yes, the connectors feature a quarter-turn locking ring that ensures a highly secure connection, resistant to vibrations and shocks—critical for the reliability of onboard electronic systems.

No, no specific tools are required. The installation is designed to be simple (plug-and-play). The connectors screw in and lock by hand thanks to their quarter-turn ring.

You can connect any Raymarine device equipped with a SeaTalk NG port. This includes, for example:

Instrument displays (i50, i60, i70s) GPS antennas Wind sensors, depth sounders, speed logs Autopilots Multifunction displays

The manufacturer’s reference for this 1-meter SeaTalk NG branch cable is A06039.

No, that is not its purpose. This drop cable (with white connectors) is designed to connect a device to the backbone. To join two backbone segments, you must use a backbone cable (with blue connectors).

The color-coding system (white for spur, blue for backbone) is designed to prevent this. Using a spur cable to extend the backbone can cause communication and power issues on your network. It is imperative to respect the network architecture by using each cable for its designated function.

SeaTalk NG (Next Generation) is Raymarine's proprietary network protocol. It is based on the NMEA 2000 standard but uses a specific, more robust and waterproof connector designed for the marine environment.

No, it is not recommended to connect multiple branch cables in series. If you need a length greater than 1 meter, it is better to use a branch cable of the appropriate length directly, such as the 3-meter model (A06040), to ensure signal integrity and network reliability.

The connectors are white to clearly identify this cable as a spur cable. In the Raymarine SeaTalk NG system, backbone cables have blue connectors, making it easy to differentiate components and prevent installation errors.

Yes, absolutely. The Raymarine SeaTalk NG connectivity system, including this cable, was specifically developed to provide superior robustness and waterproofing, perfectly suited to the demanding conditions of the marine environment.

The weight of this cable is 0.1 kg.
