AVDude, I did search, but didnt find any real clear information in the one previous thread. Anyway, I'm guessing the only option would be Xantant's IR-RS232, the only reason I dont want to use that Is a go through Russound. Furthermore, alot of the stuff I install have Ir-mini plug inputs, and I've have alot of success with those as opposed to flashers. Anyway, I guess there isn't really a solution I was looking for available, what do you guys usually use when you want to program a pronto to controll HVAC?
