I followed that link. The description makes fairly clear that the program generates only the IR protocol used by Sharp and Denon.

To use that program you need to input the four parts of a Sharp/Denon signal in binary with the division of bits (5 bits, 6 bits, 2 bits and 2 bits) that Denon normally uses for documenting their signals. If you use non binary characters or the wrong number of bits, that program gives no error message, it just produces garbage output (not just not correct Sharp/Denon signals, but something that isn't any kind of an IR signal because it isn't structurally correct Pronto Hex).

Anyway, if you want anything other than creating a Sharp/Denon signal from documentation in binary, it's the wrong program.
