The workflow is connect, read the module to display vendor/model/wavelength, load a new firmware file and write it, with editable parameters and automatic recalculation, password entry for third-party manufacturer modules, memory dump export, and access to A0h/A2h upper and lower regions.

Read the module as a template, load the target vendor firmware, enter the module password if protected, let the tool recalculate checksums and write; export a dump first as a backup.
