MT+
A Windows app that runs alongside Maintenance Tool on the same M-NET USB converter. It finds every unit, draws each system, and reads DIP switches, error history and function settings.
Legacy Controller Upgrade Tool
Connect to a legacy Mitsubishi centralized controller (AG-150, G-50, and similar) over the network and build an AE-C400A configuration file. Group names, M-Net addresses, unit types, blocks, icons, and network settings are carried across automatically — no manual re-entry. Open the resulting .dat file in the AE-C400 Initial Setting Tool to review it and write the configuration to the new controller.
If your IT policy blocks .exe files, the download also includes a no-install alternative (an .hta or PowerShell script) that extracts the same data to a .json file — upload it here on Config Tools to generate the .dat instead. See the README inside the "No-EXE Alternative" folder.
