ST 3-port connection box

The Raymarine 3-port ST connector box (part number D244) is a component designed to simplify the interconnection of multiple instruments and sensors within a SeaTalk1 network. It serves as a centralized junction point to organize and extend your SeaTalk1 wiring.

This box is used to centralize connections for multiple SeaTalk1 devices. It creates junction points to connect up to three instruments or SeaTalk1 network segments, simplifying installation and wiring organization aboard your boat.

The D244 connection box is equipped with three dedicated ports. These ports allow simultaneous connection of up to three devices or cable segments compatible with the SeaTalk1 protocol.

This unit is exclusively compatible with systems and instruments using Raymarine's SeaTalk1 data protocol. It is designed to work with older Raymarine equipment based on this architecture.

No, the D244 connection box is specifically designed for the SeaTalk1 protocol. It is not directly compatible with SeaTalkNG (Next Generation) or NMEA 2000 networks, which use different protocols and connectors. Specific converters are required if you wish to interconnect SeaTalk1 systems with SeaTalkNG/NMEA 2000 networks.

The D244 unit is installed directly. It integrates into standard SeaTalk1 wiring architectures. Secure it in a dry, protected location, then connect the SeaTalk1 cables from your instruments to the available ports on the unit. Ensure all connections are fully inserted to maintain signal integrity.

No, the 3-port ST connection box (D244) is a passive component. It does not require a separate power supply. Power for SeaTalk1 instruments is typically provided via the SeaTalk1 data bus itself, sourced from one of the devices connected to the network.

The D244 connection box is generally not designed for direct exposure to the elements. It is recommended to install it in a dry location, protected from moisture and splashes, such as behind a dashboard or in a technical compartment, to ensure its longevity and the reliability of the connections.

You can connect any Raymarine instrument or sensor that uses the SeaTalk1 communication protocol. This typically includes multifunction displays, autopilots, wind transducers, logs, depth sounders, and other SeaTalk1-compatible devices.

No, the D244 connection box is usually sold separately. The SeaTalk1 cables required to connect your instruments to the box must be purchased separately, based on the lengths and specific needs of your installation.

The SeaTalk1 protocol is a proprietary data bus developed by Raymarine to enable communication and data sharing between different navigation instruments onboard a boat. It transmits data such as speed, depth, wind direction, heading, etc.

No, this device is designed specifically for Raymarine's SeaTalk1 protocol. Instruments from other brands that do not use the SeaTalk1 protocol cannot be directly connected to this device or communicate via this network.

To extend a SeaTalk1 network, disconnect an existing cable from an instrument or another junction point, then connect it to one of the D244 housing ports. Use the remaining ports to add new instruments or extend the network to other areas of the boat with additional SeaTalk1 cables.

Although there is no strict limit on the number of passive boxes like the D244, it is important to consider the total length of the SeaTalk1 network and the number of connected instruments. Too many junctions or excessive cable length can potentially affect signal integrity. It is recommended to consult Raymarine's specifications for maximum cable lengths and network configurations.

Yes, one of the main benefits of the D244 connection box is optimizing cable management. By centralizing the connections of multiple instruments at a single point, it allows for a cleaner and more organized installation, reducing clutter and making maintenance easier.

The D244 housing is not designed to directly repair a damaged cable. However, it can be used to bypass a damaged cable section by replacing it with a new cable segment and using the housing as a junction point to reconnect the network. For cable repair, it is preferable to use suitable connectors or splices.

You can check the compatibility of your instruments by consulting their user manual or the manufacturer’s technical specifications. SeaTalk1 instruments are generally identifiable by their specific 3-pin connectors and the SeaTalk1 logo or protocol mention in their documentation.

Raymarine products are covered by the manufacturer's standard warranty. To find out the specific details of the warranty applicable to this D244 connection box, including its duration and terms, please consult Raymarine's official documentation or contact our customer service.

This connection box is shipped in standard marine electronics packaging, designed to protect the product during transport. It is usually shipped alone, without cables or additional accessories, unless otherwise specified.

The D244 unit itself is a passive component and does not actively "improve" network performance in terms of speed or signal strength. However, by ensuring stable and reliable connections and enabling clean cable organization, it helps maintain signal integrity and proper communication between instruments, which is essential for optimal SeaTalk1 system performance.
