Raymarine ST-Ng to DeviceNet Female

Bridge the gap between modern Raymarine networks and legacy marine systems with this essential adapter cable. Designed for seamless integration, it transforms your SeaTalkng backbone into a DeviceNet female connection over a compact 400mm length, minimizing clutter while maximizing connectivity on your vessel.

Why This Adapter Matters for Your Marine Setup

In the world of boating electronics, compatibility is king. Raymarine's SeaTalkng protocol powers a wide array of instruments, autopilots, and multifunction displays, but many engines—like those from Volvo Penta or older propulsion systems—still rely on DeviceNet for data sharing. This adapter eliminates the need for bulky converters or rewiring, letting you pull critical engine data such as RPM, fuel flow, and temperature directly into your Raymarine chartplotter or radar system.

Boat owners and installers rave about its plug-and-play reliability. No more hunting for proprietary cables or risking signal loss during rough seas. It's built tough with marine-grade materials to withstand saltwater exposure, vibration, and temperature swings common in harsh marine environments.

Key Features That Set It Apart

• Precise Length: 400mm backbone cable keeps your helm tidy without excess wiring.
• Female DeviceNet End: Direct mating with male DeviceNet ports on engines or sensors.
• SeaTalkng Optimized: Ensures full-speed data transmission up to 250 kbps, matching NMEA 2000 standards.
• Durable Construction: UV-resistant jacket and tinned copper conductors for corrosion resistance and long-term performance.
• Zero Power Draw: Passive design means no additional power supply needed.

Perfect Compatibility Scenarios

This cable shines in hybrid setups. Pair it with Raymarine Axiom series MFDs to display engine telemetry from DeviceNet-equipped outboards or inboards. It's also ideal for retrofitting older boats where SeaTalkng evolves your network without a full overhaul.

• Volvo Penta IPS and diesel engines with J1939/DeviceNet interfaces.
• Caterpillar marine engines requiring CAN bus bridging.
• Third-party sensors like fuel tanks or windlasses using DeviceNet.
• Commercial fishing vessels blending Raymarine nav gear with industrial controls.

Pro tip: Always verify your backbone terminator is in place downstream to maintain network integrity. This prevents data echoes that could freeze your displays mid-voyage.

Installation Made Simple: Step-by-Step Guidance

Getting up and running takes minutes, even for DIYers. Here's how:

1. Power down all electronics and disconnect batteries.
2. Locate your SeaTalkng backbone spur port (white cable with yellow connectors).
3. Plug the SeaTalkng end into the spur; connect the DeviceNet female to your engine's male port.
4. Secure with cable ties, avoiding sharp bends.
5. Power up, then use Raymarine's SeaTalkng tools or LightHouse software to confirm the new device appears.

If data doesn't flow, check polarity—DeviceNet and SeaTalkng share CAN protocols but watch for inverted signals on some older gear. A quick multimeter test on pins A/B ensures foolproof hookup.

Troubleshooting Common Hiccups

Network gremlins happen. Start with these fixes:

• No Data Showing: Confirm 12V supply to the backbone and DeviceNet source.
• Intermittent Connection: Inspect for pinched wires or loose waterproof seals.
• Overload Errors: Limit spurs to five devices per backbone segment.
• Compatibility Clash: Update Raymarine firmware via microSD for latest protocol support.

Regular maintenance? Wipe connectors with isopropyl alcohol annually to banish salt buildup.
