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 BEC or BEC2 format. Both are end-to-end encrypted to protect the sensitive project keys during transmission to other devices.

The differences are described below:
