I have a similar situation. I needed discreet IR codes for a Sharp PN-L702 monitor. The manufacturer's rep sent me a document that says it follows the '48 bit code standard of the Association for Electric Home Appliances'. For 'power on' it would be 0x555AF468808A where the only thing that changes for the different functions is the last 4 bytes (808A). How do I change these 48 bit commands into the modulated Pronto hex format that my AMX IR edit program can understand?
