The hex string was exactly as I typed in. I access the code to a command on the right hand side of the device page in the ProntoEdit4.0 software. It then showed me a bunch of different commands (e.g. Power On, Power Off, plus a bunch of other commands). I then hit View IR as someone had suggested on this thread. That's when the 8000 ............. code appeared. I copied this code by right clicking an use a Copy command. Then I went to my T2 device page where Hex codes can be pasted to correspond to a particular command (e.g., Power Off). That's when I got the message that it was an Unknown Code Type Detected.

As I said, this use to work fine with the old ProntoEdit software, but that was many years ago since I tried doing this. This is the first time I'm using ProntoEdit 4.0 software.

Thanks.
