<h3>Actisense: The NMEA Specialists in Marine Network Technology</h3><p>Actisense was founded in 1996 when engineer and sailor Phil Whitehurst set out to make marine electronics simpler and smarter. Seeing too many devices fail in tough conditions, Phil built the brand around a commitment to reliable hardware, intelligent software, and industry-leading customer support. What started as a small operation on England's south coast has since grown into one of the most respected names in marine electronics worldwide.</p><h3>A Global Leader in NMEA Technology</h3><p>Actisense is a proud British manufacturer exporting to over 75 countries. Their award-winning brand has earned a reputation throughout the industry as &quot;The NMEA Specialists,&quot; a title backed by genuine technical authority. Actisense's expertise has led them to become National Marine Electronics Association (NMEA) Committee members, helping to shape the industry standards of NMEA 0183, NMEA 2000, and the new NMEA OneNet&reg;.</p><p>Actisense was named Manufacturer of the Year at the 2024 NMEA Conference and Expo, a recognition that reflects decades of engineering innovation and dedication to the marine community. The Actisense product portfolio includes data converters, buffers, multiplexers, network interfaces, and diagnostic tools that simplify and strengthen marine data systems.</p><h3>What Actisense Makes</h3><p>From NMEA 0183 and 2000 converters to diagnostic tools and smart interfaces, Actisense solutions make it easy to convert data, digitise signals, and share critical information reliably across marine systems. Whether you're outfitting a weekend sailboat or a commercial vessel, their products are engineered to perform in the harshest maritime conditions.</p><p>At the core of any Actisense-equipped boat is a robust <a href="/13789-actisense-nmea-2000-interface-cables-and-connectors-200717">NMEA 2000 interface cables and connectors</a> network. These components form the backbone of onboard data communication, linking everything from chart plotters and depth sounders to autopilots and engine monitors. Actisense's expertise in this area is unmatched, and their connectors and cabling solutions are designed specifically to meet the demands of demanding marine environments.</p><p>Beyond connectivity hardware, Actisense offers a broad range of electronics parts and accessories that extend and enhance the capability of NMEA-based systems. From power management to signal distribution, these accessories help mariners build cleaner, more capable onboard networks. For those focused on situational awareness and voyage planning, the brand's navigation parts and accessories tie seamlessly into the wider NMEA ecosystem, enabling reliable data flow to the instruments that matter most.</p><h3>Built for Real-World Conditions</h3><p>Actisense builds intelligent marine electronics that help people around the world understand what's happening onboard, safely, reliably, and in real-time — trusted in some of the toughest marine environments, from superyachts to commercial fleets. Their product range is held in high regard throughout the industry because of its quality, durability, and technical sophistication. For any mariner serious about the integrity of their onboard network, Actisense represents a gold standard in NMEA technology.</p>

Product Details

The Actisense OPTO-4 is a bi-directional NMEA 0183 (RS422) to RS232 interface adapter that provides safe, isolated connectivity between marine navigation systems and computers or devices with standard RS232 9-pin serial ports. Designed to protect against ground loops and voltage spikes, this adapter uses optical isolation to prevent potentially hazardous voltages on the NMEA 0183 bus from damaging connected PC hardware.

Key Features:

  • Opto-isolation providing 2000 volt protection on the PC input line
  • Full duplex (two-way) communication for simultaneous data transfer
  • NMEA 0183 and RS232 compliant with support for all baud rates up to 115200
  • Port-powered design draws power directly from the PC serial port for simple installation
  • Overmolded waterproof case with narrow profile fits in tight installation spaces
  • Fully shielded construction provides superior noise rejection in commercial environments
  • Transient protection and reverse voltage protection on PC lines
  • Current limited circuitry protects against cable faults

The OPTO-4 is particularly well-suited for commercial vessels and electrically noisy marine environments where equipment protection is critical. The compact, waterproof design and port-powered operation make installation quick and trouble-free without requiring external power supplies.
