Board package for code 5LXWL, revision suffix RH-11, stored as a 1.53 MB RAR archive. The name identifies only the board, not the document type, so whether a schematic, boardview or firmware image is inside must be checked after extraction. Technicians use such files to locate components, measure test points and track down shorts on power lines. Confirm that the PCB silk-screen shows the same code and revision, since the RH-10 board from the same family may not match exactly.
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.
