Understanding NMEA Data Consolidation Challenges
Managing NMEA 0183 data presents a fundamental challenge in marine electronics. You cannot connect two talkers directly to a single listener connection, which creates operational limitations when integrating multiple instruments. Consequently, multiplexers solve this critical problem by allowing you to consolidate data from numerous sources into fewer outputs. Additionally, this approach ensures seamless communication between your GPS, wind instruments, AIS systems, and depth sensors. Furthermore, modern vessels increasingly demand flexibility in routing data to multiple displays and chartplotters simultaneously.
PRO-NDC-1E: The Versatile Standard Solution
The Actisense Pro NMEA Multiplexer PRO-NDC-1E represents an excellent choice for recreational and smaller commercial vessels. This model features five isolated NMEA 0183 listener inputs and two isolated talker outputs, alongside a dedicated serial port and Ethernet connectivity. Therefore, you benefit from maximum flexibility when planning your installation. The unit supports baud rates from 4800 to 38400 bps, accommodating both legacy and modern instruments. Moreover, the talker output delivers 20mA of current drive with protection against short circuits and ESD interference. The listener inputs tolerate continuous voltages from -15V to +15V, with short-term protection extending to ±35V.
PRO-NDC-1E2K: Gateway Between NMEA Standards
The PRO-NDC-1E2K extends capabilities by adding full NMEA 2000 gateway functionality. Specifically, this model bridges legacy NMEA 0183 networks with modern NMEA 2000 systems through bidirectional conversion. This means you can integrate older instruments without purchasing replacement equipment. The device supports streaming NMEA 2000 data over Ethernet, enabling remote monitoring and integration with advanced navigation platforms. Additionally, the OPTO-isolated NMEA 2000 port provides enhanced protection against electrical interference. Therefore, vessels transitioning from 0183 to 2000 architecture find this device invaluable for maintaining mixed-system compatibility.
PRO-MUX-2: Professional-Grade Large Vessel Solution
The PRO-MUX-2 delivers enterprise-level multiplexing capability for complex marine networks. This device provides eight isolated NMEA 0183 inputs and six outputs, substantially exceeding smaller models. Besides expanding port capacity, it adds relay alarm outputs with both normally-open and normally-closed contacts. Additionally, the bidirectional serial port supports more advanced data protocols. Furthermore, the OPTO-isolated inputs provide superior protection compared to ISO-Drive technology. Consequently, commercial fishing vessels, research ships, and large yachts benefit significantly from its enhanced capability and reliability.
Advanced Features Across All Models
The filtering and routing capabilities transform how you control marine data flow across all three platforms. Specifically, you monitor, filter, pass, or block individual data sentences based on your operational requirements. The configuration tools work on any popular web browser across any operating system, removing platform limitations. Besides offering flexibility, this approach simplifies installation and reduces troubleshooting time considerably. All models feature 316 stainless steel construction, supporting operation between -25°C and +70°C. Therefore, they withstand harsh marine environments without compromise. Additionally, each device carries type approval certification from RINA and meets stringent EMC standards.
Selecting Your Ideal Multiplexer
Choosing between these solutions depends on your specific requirements. Small recreational vessels typically need only the PRO-NDC-1E for basic consolidation. Conversely, vessels combining NMEA 0183 and NMEA 2000 systems benefit from the PRO-NDC-1E2K gateway. Finally, large commercial operations require the PRO-MUX-2’s expanded capacity and relay integration. Regardless of your choice, Actisense devices deliver reliable, marine-grade performance backed by comprehensive support.
