I have an excel sheet that I use to calculate the check sum. If can be downloaded
here. For proper calc operation the Add-In, "Analysis ToolPak" will need to be installed/enabled in Excel. The first tab of the excel sheet is for Sony receivers. The second tab of the excel sheet is for the
Sony BDP-CX7000ES 400-disc Blu-ray changer.
