Actisense PRO-BUF-2 – Intelligent, type-approved NMEA 0183 Buffer
The Actisense PRO-BUF-2 is a smart solution for securely and reliably distributing NMEA 0183 data to multiple onboard devices. This ensures your navigation, communication, and safety systems always receive the correct information – without interference or data loss. The result: more reliable sailing, fewer error messages, and a more peaceful experience on the bridge.
Who is this system made for?
- Sailing and motor yachts with multiple displays/sensors that need to receive the same data.
- Work and fishing vessels where robustness and type approval (IEC 60945, IACS E10) are required.
- Refit projects that combine old and new equipment and require reliable distribution.
Key Features
- 12 ISO-Drive™ outputs & 2 opto-isolated inputs – powerful distribution with full isolation.
- Ethernet interface – configuration, diagnostics and UDP/TCP data streaming via web tool.
- Flexible operating modes – buffer, intelligent autoswitch and combiner; automatic baud rate matching.
- Diagnostics – LEDs for power/in/out/alarm + real-time statistics and load per port.
- 316 stainless steel housing – bulkhead or DIN rail mounting; suitable for 12/24 V on-board systems.
- Type-approved – including IEC 60945 and IACS E10; RINA certificate.
What's in it for you?
- Reliable distribution: stable data without ground loops or overload.
- Easy setup: Web-based tool in any browser; no extra software or hassle.
- Fast troubleshooting: clear LEDs and web statistics per port.
- Flexibility: Advanced filtering/routing and virtual autoswitch modules.
- Future-proof: firmware updates via Actisense Toolkit (Ethernet).
