I have tried to reverse engineer remote control keyboard set that I have. I was sucessful at reverse engineer protocol with my Saleae Logic Analyzer. But the I was not able to receive data that remote is sending. So if somebody fells that can continue where I ended - here are all my knowledge and data files.Files are below on the bottom on the page. To display waveforms, you can download Saleae Logic software and open decoded comunication. In the text file, there's also decoded initialization sequence with decoded RF channel and address. I had no luck with that info, probably I just haven't set my receiver just right, but I have no more time to experiment.
