MiniPlex-3E NMEA 0183 Multiplexer with Ethernet Interface

The MiniPlex-3E by ShipModul is an advanced NMEA 0183 multiplexer designed to combine data from multiple marine navigation instruments into a unified Ethernet stream. Equipped with four galvanic isolated NMEA 0183 inputs and two flexible outputs, the MiniPlex-3E allows onboard chartplotters, PCs, tablets, and smartphones to seamlessly receive real-time AIS, GPS, depth, and wind data over standard network cabling or wireless routers.

Featuring built-in support for both TCP and UDP protocols, the MiniPlex-3E transmits navigation sentences directly to marine apps like OpenCPN, iNavX, or TimeZero without needing USB drivers. Integrated SeaTalk translation enables older Raymarine instruments to integrate directly into modern Ethernet-based marine networks.

Key Features of the MiniPlex-3E

• Ethernet Connectivity: Stream marine instrument data directly over 10/100 Mbps Ethernet to onboard computers, mobile devices, or Wi-Fi routers

• 4 NMEA 0183 Inputs: Galvanically isolated inputs eliminate ground loops and protect connected instruments from electrical damage

• SeaTalk Translation: Converts Raymarine SeaTalk data into standard NMEA 0183 sentences for unified network integration

• Flexible Filtering & Routing: Fully configurable NMEA sentence filtering, routing, and baud rate conversion (up to 115,200 baud for AIS)

• UDP & TCP Protocol Support: Compatible with both unicast/multicast UDP for multiple wireless clients and TCP for dedicated host connections

• Low Power Consumption: Operates efficiently on standard 8V–35V DC vessel power networks
