EPROM ProgrammingAll files are Intel Hex ASCII format. File extensions should match chip designations onthe board.7.11.3. DownloadTo start a download from CAAPE, select a downloadable application and:1. Go to Actions | Utilities in the main menu.2. Click the Download button on the main toolbar.3. Right click on the application folder and select Download from the popup menuThe Download Utility is launched and the application and system files are loaded andready for download.Selecting Download with anything else selected just launches the Download Utilitywithout loading any files.7.11.4. Checksum ValuesThe checksums reported by the PROM Split utilities and reported in the application’sconfiguration report are simple additive values which can be compared against thechecksums produced by the EPROM programmer. In VPI CAA 027B and CenTraCodeII-s CAA 014B and later, the EPROM files fill all unused areas with hexadecimal FFvalues; as long as the recommended memory device is used, no prefilling of theprogrammer’s memory buffer is needed. For earlier CAA versions, or when a largermemory device is used than the one recommended, prefill the programmer’s memorybuffer with zeroes.P2512A, Rev. Oct/09 7–36 Alstom Signaling Inc.
