ZIP package named NexusBV, version 0.5.1, which from its name appears to be a boardview viewing program rather than a dump for any specific device. No brand, model or board number is given. Boardview viewers let a technician open board layout files to locate components, test points and nets, and to follow a signal across layers while probing. Extract it and check the included files and instructions before use. Confirm which boardview formats it supports, because many vendor formats need a particular viewer.
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 @biosdumpcomputer. Enginerys does not host this file.
