EEPROM and automatically applied during deployment Memory Data The SBE 48 has a 2 MB FLASH memory for data storage FLASH memory is non volatile and data in the memory is not lost as a result of depletion or removal of the battery Because FLASH is written to a page 256 bytes at a time data is first accumulated in a 256 byte cache buffer When the cache is full its contents are transferred to FLASH memory The cache is volatile and thus depends on battery power That is why an SBE 48 with depleted battery will lose its most recently stored data unless an external power supply is used see Uploading Data in Section 4 Deploying and Operating the SBE 48 The data upload process integrates the data from the FLASH memory with the data from the cache The SAMPLENUM command controls the memory pointers that manage this process Setting SAMPLENUM to zero resets the pointer in the FLASH memory as well as the pointer in the cache memory causing the SBE 48 to overwrite existing data It is important not to change SAMPLENUM until all the data has been uploaded 34 Appendix I Functional Description If SAMPLENUM is inadvertently set to zero before data is uploaded and you wish to upload data the following conditions apply larger than original value Was additional User then Description of Uploaded Data data logged returns after SAMPLENUM SAMPLENUM to was changed No Original value All data data in FLASH as w
