Yes - would like to check out your app. My excel spreadsheet does the same - with formulas to add up and calculate the checksum for Barco Codes.

The Barco codes work on the SLM range - I think they are the same for the RLM and XLM, not sure about the new FLM though

Panasonic codes were written for the PT-D7700U-K
According to the documents, it should also work with: PT-D7700U PT-DW7000U PT-DW7700E PT-D7700EK as they share the same software etc.
The codes may also work with the other projectors in the 'large venue' range, but I cant confirm that.
