EEPROM editor

The Editor presents a transceiver's memory as a HEX and ASCII grid so you can inspect and change it precisely.

Layout

• HEX and ASCII grid — every byte shown in both forms side by side.
• A tab per page — module memory pages are opened as separate tabs.
• Byte hints — hover a byte to see its address, its value in several number systems, the field name and the applicable specification (SFF-8472, SFF-8636, CMIS, and the SFF-8024 tables).

Editing safely

• Undo and redo for every change.
• Checksum recalculation — CC_BASE and CC_EXT are recomputed as needed.
• Page lock guards a page against accidental edits.
• Load and save dumps as files, so you can keep a copy before and after.

Editing changes the working copy in the app. Writing those changes to a physical module is a separate step — see Writing a module.

Field formats and padding rules the editor enforces: Vendor fields; what it recalculates on write: Checksums.

Field-by-field reference for what the editor labels: SFF-8472 A0h / A2h, SFF-8636 lower / upper, CMIS lower / upper / lanes, XFP.
