ShipModul B.V., a Dutch marine electronics manufacturer, announced that a new firmware, V3.37.0 was released for the MiniPlex-3 Series introducing some changes / new features as follows:
Changes / new features
The internal magnetic variation table has been updated with new data for 2026.
The Sentence Rebuild feature now removes leading “+” signs from copied fields. These are not allowed in NMEA 0183.
Transmission of $MXPGN sentences from received NMEA 0183 sentences is now also possible if an NMEA 2000 enabled MiniPlex is not connected to an NMEA 2000 network.
The last two features were also included in interim update V3.36.1 which was already available a few days earlier.
Configuration Tool
The latest MPXConfig3 V3.19.0 which was released on 17/9/2025 can still be used with this latest MiniPlex-3 firmware.

Furthermore, it should be noted that this latest MPXConfig3 version is only available for Windows and not yet for macOS. To use a MiniPlex-3 on a Mac, firmware V2.3.18 must be loaded using MPXConfig3 V2.4.1 for MacOS. The V2.3.18 firmware, however, can only be loaded in multiplexers with serial number ranges 3x00xxxx and 3x02xxxx. This firmware is not compatible with serial number range 3x01xxxx! For these multiplexers, you must use MPXConfig3 for Windows, which can be run in a virtual machine on your Mac.
ShipModul provides advanced solutions for the reliable communication of NMEA data between multiple talkers and listeners. They are offering several interfacing options (NMEA0183, N2K, USB, Ethernet, Wi-Fi …) a rich set of features and configurations while eliminating ground loops. This makes the outputs compatible with all sorts of inputs, whether they are isolated or not, differential (RS-422) or grounded (RS-232). Any combination of networks using NMEA 0183, N2K or SeaTalk data integrates seamlessly via the latest MiniPlex-3 Series NMEA multiplexers. They offer the ultimate solution to connect old and new worlds and the perfect gateway to computers and tablets onboard.
