MPX-Config is the configuration tool used for altering the settings of the MiniPlex multiplexers. From time to time we improve the firmware of the multiplexers and add new options. These options must be supported by MPX-Config. It is therefore important to match the version of MPX-Config to the version of the firmware in the multiplexer. The table below lists the matching combinations.
