Why not email or contact Panasonic for the IR commands. Many projector manufacturers have data sheets for the IR commands that they will send since people integrate their projectors into more exotic A/V systems. They already publish the commands for the serial interface on their website but I do not think that that command structure is the same since the interface is two-way.

Once you get them they will probably be in hex and I will be glad to help you decipher them and then we can hopefully figure out how to get them into your particular remote. Is there a conversion utility form regular Pronto as I can use Barry Gordon's GenIRDB to create Pronto hex.

Alternatively, I can get them into many inexpensive One-for-All remotes and you could learn the commands that you want from them.

Good luck,

Jon
