SeaTalk NG T-connector

The A06028 T-connector is an essential component for building or extending a Raymarine SeaTalk NG navigation network. It serves as a junction point to add a device, such as a multifunction display or a sensor, to the main backbone of your network.

The connector uses a color code for easy installation:

Two blue ports: These are reserved for backbone cable connections to ensure network continuity. One white port: This is used to connect the spur cable leading to the device you want to add to the network.

Yes, the SeaTalk NG network is electrically compatible with the NMEA 2000 standard. However, the connectors are physically different. To connect a device from another brand with a standard NMEA 2000 plug (Micro-C), you will need a Raymarine SeaTalk NG to NMEA 2000 adapter cable.

SeaTalk NG is Raymarine's proprietary SeaTalk NG wiring system based on the NMEA 2000 protocol. It uses specific connectors with color coding and a bayonet locking system to simplify installation and improve reliability in marine environments. Data is transmitted in NMEA 2000 format.

Yes, the bayonet locking system ensures a robust mechanical connection and perfect watertightness. It protects electrical contacts from moisture, spray, and corrosion, which is essential for durable marine installations.

No, no specific tools are required. Installation is done by hand using the connection and locking system via simple collar tightening.

Yes, this is even the principle behind building a SeaTalk NG backbone. You can chain T-connectors to create as many connection points as needed for your various navigation instruments.

No, this connector is not directly compatible with the SeaTalk1 (or SeaTalkHS) network. To integrate SeaTalk1 devices into a SeaTalk NG network, you must use a specific Raymarine conversion gateway.

The dorsale, or "backbone" in English, is the main cable line running through the boat that distributes data and power across the entire network. T-connectors are plugged into this backbone to allow individual devices to connect via drop cables.

The manufacturer reference for this Raymarine SeaTalk NG T-connector is A06028.

No, the T-connector itself does not require a termination plug. However, the entire SeaTalk NG network must have a termination plug (terminator) at each of its two ends to function properly.

You can connect any device compatible with SeaTalk NG or NMEA 2000 (via an adapter), such as:

A multifunction display (MFD)A GPS antennaAn autopilotA wind, speed, or depth sensorA VHF radio

Yes, the SeaTalk NG network carries both data and 12V DC power. This connector can therefore power connected devices via the split cable, within the network's capacity limits.

The weight of this T-connector is approximately 22 g.

No, not directly. The white port is in SeaTalk NG format. To connect a spur cable with a standard NMEA 2000 Micro-C connector, you must use a SeaTalk NG to NMEA 2000 adapter cable.

This is an official Raymarine product, designed specifically for its SeaTalk NG ecosystem.

No, the electrical orientation does not matter. You can install it in the direction that best suits your setup and cable routing, as long as the blue connections are on the backbone and the white on the branch.

Yes, as a general rule, each device (display, sensor, etc.) you wish to add to your SeaTalk NG backbone requires its own T-connector to connect to it.

No, this connector is designed to add a spur line. To extend a backbone, you must use a SeaTalk NG backbone cable of the desired length and a junction connector (I-connector) if needed, or simply a longer cable.

The A06028 product packaging contains only the SeaTalk NG T-connector. Backbone cables, spur cables, and end caps are sold separately.
