Guys, I am not sure exactly how this extender works. Does the pronto pro emit RF to the unit and it then translates to IR? Or does the extender receive IR and emit RF ? Can the RF extender be hooked up to a IR repaeter system like Zantech? Also, if the Pronto emits RF it seems it can then control Hifi equipment through a wireless network, if your equipment has an RS232 port? Is it this simple or am I smoking mayonaise ? Rgds Steve.
