STNG female back end to DeviceNet female adapter cable 400mm

This adapter cable is designed to connect two backbone networks of different technologies. It allows linking a Raymarine SeaTalkNG (STNG) backbone to a standard NMEA 2000 backbone using DeviceNet connectors. It ensures interoperability between equipment from different brands on the same boat.

Yes, indirectly. This cable does not connect the display directly, but it allows you to join the Raymarine SeaTalkNG backbone to the Garmin NMEA 2000 backbone. Once the two networks are unified, compatible devices from both brands can communicate with each other.

This adapter must be installed at the junction between your SeaTalkNG backbone and your NMEA 2000 backbone. It acts as a bridge between the two main trunks. It must not be used to connect an individual device (drop connection or "spur").

The cable itself does not require termination. When connecting the two networks with this adapter, they form a single backbone. You must remove the terminators at the junction and ensure that:

The combined network has exactly two terminators in total, located at each final end. The entire setup forms one large network that must have only two terminators in total, one at each final end of the combined network.

No, this adapter is exclusively designed for SeaTalkNG (SeaTalk Next Generation) networks. It is not compatible with older Raymarine networks such as SeaTalk1 or SeaTalk2, which use different connectors and protocols.

This cable is equipped with two female connectors:

A female SeaTalkNG connector, for connection to the Raymarine backbone. A female DeviceNet connector, for connection to the standard NMEA 2000 backbone.

No, this is not the purpose of this cable. This adapter is designed to connect two backbones together. To connect an individual NMEA 2000 device (such as a GPS antenna) to a SeaTalkNG backbone, you must use a SeaTalkNG to DeviceNet male spur cable, such as Raymarine part number A06045.

This cable connects the data and power lines of the two backbones. It is essential to follow NMEA 2000 power rules. Typically, a single power source is recommended for the entire merged network to avoid ground loops. Therefore, ensure that only one of the two original backbones (STNG or NMEA 2000) powers the combined network by disconnecting the power from the other.

This is a backbone adapter cable. Its function is to join two main trunks (backbones) and not to connect a peripheral device to the network. Spur cables typically have different connectors (white on STNG networks).

No. If your entire installation (displays, sensors, autopilots) is based on Raymarine SeaTalkNG technology, you do not need this adapter. You will use only standard SeaTalkNG backbone and spur cables to build your network.

No, no specific tools are required. SeaTalkNG and DeviceNet connectors are designed to be hand-tightened. Installation is plug-and-play, but a solid understanding of NMEA 2000 network basics (terminations, power) is strongly recommended.

Although both carry data in the NMEA 2000 format, their physical connectors are different. SeaTalkNG is Raymarine's proprietary version, with smaller connectors and a specific locking system. DeviceNet is the standard used by most other manufacturers for NMEA 2000 networks. This cable bridges the gap between these two physical standards.

Yes, this cable ensures electrical and data continuity between the two networks. All standard NMEA 2000 data (PGN sentences) present on one backbone will be transmitted to the other, allowing compatible devices to share information such as GPS position, speed, depth, wind, etc.

To connect backbone segments, you often tap into the end of an existing network, which may terminate in a T-connector or an extender. SeaTalkNG T-connectors have male ports, and NMEA 2000 T-connectors have one male port and one female port for backbone connection. This cable, with its two female connectors, is designed to plug into the male ports of these T-connectors, thereby extending each backbone to the junction point.

Yes, like all Raymarine SeaTalkNG and certified NMEA 2000 cables, this product is designed to withstand the marine environment. The connectors feature O-rings to ensure a watertight and reliable connection, protecting the contacts from corrosion and moisture.

No, that is not its function. To extend a SeaTalkNG backbone, you must use a SeaTalkNG backbone extension cable (blue) with STNG connectors at both ends.

No, the cable is bidirectional. You can connect the SeaTalkNG connector to the Raymarine backbone and the DeviceNet connector to the NMEA 2000 backbone, or vice versa. Data and power flow in both directions without distinction.

This cable resolves physical connectivity issues between SeaTalkNG and NMEA 2000 networks. It does not resolve software compatibility problems. If an older device is not programmed to understand the data (PGN) from a newer device, they will not be able to communicate even if the physical network is correctly unified.
