I am trying to control a LM465 lamp module with my Harmony 650 remote and need to convert the IR signal to X10. The IR-543 does this but it has been discontinued. I have tried to buy it from 4 separate places so far and every place has ended up refunding me my money since they no longer have it. Is there any replacement for this part? If not does anyone know where I can find one? It looks like there are a few places that may have it but I don't want to spend $50 on this yet.
