Re..using Universal Remote controls ?

I managed to get my Pronto remote control to work with the IMON system. In the pronto software I programmed in a delay then send the IR signal and it works. so the program now reads, delay 0.1s then send IR. It is working fine for me now.

Hope it helps. If you succeed please let me know, i am expecting my pronto (RU950) in next few days.

regards,
alejo
