How do you read/convert the Hexadecimal Data into text

[Rusty Haight]

No, a "report preview" is generated not a PDF at that step. The PDF step requires clicking on the PDF icon at the top bar in the legacy software to generate the PDF from the preview. Within the CDR Tool software, the report preview is a separate function, it does lead to the potential for generating a PDF or for printing to paper, but the report preview within the tools is a distinct step.

The Hex section at the end of every report is a display of the data retrieved. Historically, it was done for GM systems starting with version 1.0 back in 2000 so a GM engineer could look at the hex data and make sure the translation in the larger data translation report was done properly. GM used to have a hexadecimal translation tool and then, with the CDR software there was an engineering translation report (ETR) function. The latter was removed to prevent reverse engineering.

The data translation report IS the conversion of the data to correspond to the data element in the larger data translation report data tables. Without more specific information from an OEM on how they have instructed Bosch to do those translations, there's no way to make any further comparisons short of some reverse engineering.

As to tampering and editing, once the data is retrieved and a CDRx file is created, it includes digital security. If one were to try to edit the hex data in that format - in the original CDrx file - it would render the CDRx file digitally incompatible with the CDR Tool software and you would not be able to generate a report preview, a PDFf or print a copy of that data as a data translation report if the underlying binary - represented as hex - has been altered or otherwise corrupted.
