I have a Screen Innovations Screen backlit LED Screen. I am trying to figure out how to convert the codes I received from them for IR to be used in my RTI processor. I am new to this so I am a bit lost. Lets take one code for example: Power Off is listed as 20 13 40 BF and IR remote control protocol is NEC:6121 Can someone please help me with the process to convert this to a pronto format so I can use it in my RTI processor?

FYI, I found this site, [Link: irdb.tk] but I don't know how to combine the data received from SI to convert it.

Thank you so much.
