Write firmware to the transceiver's memory
From SFPTotal Wiki
Due to mismatch of the majority of the modules to the MSA standards because of installed special controllers or use non-standard ways of writing firmware into transceiver’s memory by the manufacturers, SFPTotal software implements two different approaches.
Programming according to MSA standards
If transceiver supports writing the memory according to the MSA standards for the selected type of module, software sends a command to the programming board that implements the algorithm of writing into the memory.
Programming using scripts
When the first option does not work for the selected transceiver, writing into memory is made with a special set of commands (scripts) that are sent to the programmer for a realization of custom writing algorithm, supported bytransceiver.
