It is indeed standard RC5 but learning is not always easy since RC5 has a Toggle bit. I think that the Pronto can learn and deal with RC5 better than most remotes.
The best explantion for the RC5 coding is probably here.
[Link: sbprojects.fol.nl]Be specifc and tell us what you want to do beyond understanding how it works.
It sounds like the manufacturer would probably tell you if it responds to discrete power codes if any.
If you want to generate all the commands in Pronto hex then there are some utilities that can be used.
