thanks for your answer. I'm not sure PDAWin supports RF yet, but in the output section I can currently select IR, but I also see that RF is greyed out for the moment, which led me to believe it may, but this remains to be proven.
Regarding RF frequency, I don't have a clue to be honest, I'm just trying to find a solution to this, so this is a bit technical for me.

Would Wifi be solution to my problem?

Could I use the standard Pronto RF IR converter (once I have found a way to send RF signal...)?

THanks
