Is it possible to make a meaningful conversion from a Pronto 2 UDB code to an EFC code? I have performed a search on EVERY forum here and couldn't find a single reference to this topic.

I do not own a Pronto. I was able to find what may be a discrete ON/OFF pair for a Hughes DSS receiver. I would like to try this on my RS 2104. Unfortunately I don't have a clue as to how to figure out a possible EFC value. I went so far as to save the Pronto file as a Pronto 1 file so that ccf2efc could convert it. ccf2efc simply placed an entry indicating that the button was a "UDB" code. No translation to EFC was indicated.

Thanks for any help.
