MPX-Config3 changelog

Version Date Description

New Feature

A checkbox has been added to enable 10Hz output of GGA, GLL, RMC and VTG sentences.

Bug Fixes

Fixed an error that caused MPX-Config3 to show an error message on startup ("B0 is not an integer value").


Bug Fixes

The priority sentence read from the MiniPlex showed a '/'-character on the last position where it should have had a '0'. This in turn caused MPX-Config3 V2.4.0 to lock up. This has been fixed in the firmware and in MPX-Config3 V2.4.1.


This version of MPX-Config3 matches the new V2.0 firmware. This firmware is embedded in MPX-Config3 and will automatically load into your MiniPlex-3 when connected for the first time.

Warning: This update erases the current configuration of your MiniPlex-3! Also, the new MPX-Config3 V2.4.0 will not read any old configuration file correctly. We advise to make screen shots of the current configuration using the previous version of MPX-Config3 first.

The Mac OS X version is still being developed.


New Features

Automatic Update

MPX-Config2 always checks if multiplexer contains the required firmware version. If not, it automatically starst an update, using a firmware image embedded in MPX-Config. Menu option Automatic Update allows a manual initiation of this update process. This feature is useful in case an automatic update fails and the multiplexer is left without any firmware. It isnow no longer necessary to go on-line to download the firmware first.

Support for new conversions

Checkboxes added for the following conversions:

  • COG to True Heading (VTG -> HDT)
  • Time from GPS (RMC -> ZDA)

NMEA Viewer

The NMEA viewer now stores up to 100 sentences and can be scrolled back for inspection.

Bug Fixes (Windows version)

    The overflow LEDs did not work because of an error in decoding of the PSMDOV sentence.

Bug Fixes (OS X version)

Headings above the filter list are fixed. Some of the headings were too wide for the column widths, especially after upgrading to OS X 10.10.


Versions are numbered as 'Vm.n.p'. These numbers have the following meaning:


Major version number. This number changes when significant improvements to the firmware are made.


Minor version number. This number changes when small features are added to the firmware.


Patchlevel number. This number changes when bugs are fixed. The feature set remains the same.

When 'm' or 'n' are changed, a new manual will be available as well as a new matching version of MPX-Config.
