Hi Kiran,
If I don't see wrong Luca Gallina's web site ("www.runmode.com":http://www.runmode.com ) has one, or (i dont remember good) there is a mapping of this protocol ... if you are a programmer I think that you don't spent much time for make a correct driver, or contact Luca Gallina directly, he sicurely has a copy for Turbo Pascal and Delphi languages.
Look at the URL below there u can find, for downloading, the manual of CP521 comunication processor, inside (index 8) there are the specifications about Sie3964R driver with RK512 procedure
