BALTECH file formats

The following file formats are currently in use for BALTECH configurations and firmware:


BALCFG is the editable configuration format. BALCFG files are also used to create ConfigCards in ConfigEditor.


When you release a configuration, a deployable file is exported in BEC2 or BEC format. Both are end-to-end encrypted to protect the sensitive project keys during transmission to other devices.

The differences are described below:

  • ToolSuite v4.26 or above
  • Firmware 1100 v2.00 or above (or custom firmware originally created as of November 2021).
Disable the option Support Legacy Firmware Versions (disabled by default for new and copied configurations as of ToolSuite v5.00)
BEC Legacy format
