RAR archive for VM8 with the word landrex in its name, 120 KB. Neither the brand nor the revision is stated, and the meaning of landrex is unclear, possibly a source or variant tag. The small size suggests boardview data or a firmware image. Unpack it and identify the files before use. For boardviews, open them in a suitable viewer to locate components and test points. For dumps, back up the existing chip and verify the size matches before programming.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cyberlanelectonik. Enginerys does not host this file.
