Actisense PRO NMEA Buffer Solutions: Isolate and Distribute Your NMEA 0183 Data Safely

The Actisense PRO NMEA Buffer lineup delivers professional-grade isolation and amplification solutions that transform how you manage NMEA 0183 data distribution across your marine network. Whether you operate a small cruising boat requiring basic signal isolation or a large commercial vessel needing to distribute data to multiple displays, Actisense provides type-approved buffer technology. These rugged devices enable you to safely connect a single talker to multiple listeners while maintaining complete electrical isolation and consistent signal quality.

Feature Comparison: Two Professional Buffer Solutions

Understanding NMEA 0183 Distribution Challenges

Managing NMEA 0183 signal distribution presents a fundamental challenge in marine electronics systems. You cannot connect multiple listeners directly to a single talker source without degrading signal quality and risking electrical ground loops. Consequently, isolation buffers solve this critical problem by amplifying the talker signal and distributing it safely to multiple devices. Additionally, isolation prevents ground loop damage that occurs when devices connect through multiple earth paths. Furthermore, professional installations demand devices that maintain signal integrity across long cable runs and harsh marine environments.

PRO-NBF-1: Compact Solution for Essential Distribution

The Actisense PRO NMEA Buffer PRO-NBF-1 represents an ideal choice for recreational vessels and smaller commercial applications. This model features one OPTO-isolated NMEA 0183 input and six ISO-Drive outputs, distributing identical amplified data streams to multiple listeners. Therefore, you benefit from reliable signal distribution without additional configuration complexity. The device supports baud rates from 4800 to 115200 bps, automatically detecting input baud rate without manual setup. Moreover, the OPTO-isolation on the input meets the latest NMEA 0183 specification requirements, protecting your talker device from ground loop damage. The ISO-Drive technology on each output provides galvanic isolation, ensuring each listener receives optimal signal voltage levels.

PRO-BUF-2: Advanced Solution for Complex Marine Networks

The PRO-BUF-2 extends capabilities significantly for larger vessels requiring enhanced functionality. Specifically, this model provides two OPTO-isolated inputs and twelve ISO-Drive outputs, substantially exceeding smaller buffer capacity. Beyond expanding distribution channels, it includes a bidirectional serial port supporting baud rates up to 115200 bps. Additionally, the integrated Ethernet port enables remote configuration using any web browser across any operating system. Furthermore, the relay alarm output with normally-open and normally-closed contacts integrates seamlessly with onboard alarm systems. Therefore, commercial fishing vessels, research ships, and large yachts benefit significantly from its advanced routing and control capabilities.

Advanced Filtering and Configuration Features

The Actisense PRO NMEA Buffer products incorporate sophisticated data management capabilities across both models. Specifically, the PRO-BUF-2 allows flexible operating modes including buffer modes, intelligent autoswitch, and combine modes. The web-based configuration tool provides fine-tuning of data available on each output, avoiding data overloads. Besides offering flexibility, this approach enables advanced data filtering and routing tailored to your specific requirements. The automatic baud rate matching on inputs removes configuration complexity entirely. Additionally, diagnostic LEDs indicate power, data flow, and alarm status, providing immediate visual feedback during installation and troubleshooting.

Durability and Marine Certifications

All buffer models feature robust 316 stainless steel construction, supporting operation between -25°C and +70°C across virtually every marine climate. The ISO-Drive isolation technology provides Hi-Pot testing to 1000V on all outputs, protecting connected devices from electrical transients. Additionally, the OPTO-isolation on inputs delivers equivalent protection standards. Each device carries type approval certification from RINA and meets stringent EMC standards including IEC 60945:2002-08 and DNVGL-CG-0339:2019. Furthermore, the IP40 environmental protection rating ensures reliable operation in spray and wet conditions. The pluggable connector systems allow quick installation and simple troubleshooting through straightforward unplugging operations.

Selecting Your Ideal NMEA Buffer

Choosing between these solutions depends on your specific distribution requirements. Small recreational vessels typically need only the PRO-NBF-1 for basic distribution to multiple devices. Conversely, larger commercial operations benefit from the PRO-BUF-2’s expanded output capacity and advanced configuration options. Additionally, if you require remote configuration via Ethernet or alarm integration, the PRO-BUF-2 delivers these professional-grade features. Finally, both devices deliver reliable, marine-grade performance enabling safe data distribution across your entire NMEA 0183 network.
