The Apple protocol revisited

If you have learned signals that don't get decoded when you look at them in IR.exe, post your file to the Diagnosis Area then post your question here (including a link to the file).

The Wiki pages confuses me because it doesn't seem to list the field types in the right order, regardless of whether I read the data left-to-right or right-to-left, and they don't list the Pairing device code.

They have them in the order:
Vendor, Command Page, Device ID, Command, Odd parity

Whereas I believe the correct order is:
Command Page, Vendor, Odd parity, Command, Paring device

Using your cross-reference of device codes to command page codes, I think I have figured out what you're asking for. I have also added the codes for command 00 from the Wiki page.

The following spreadsheet has 2 tabs, v1 for how we read the codes in JP1, and v2 for how I think you're asking us to read them. The only change that I made was to split the 11-bit vendor code into 2, as I don't like to have codes longer than 8-bits unless there's a good reason to. In this case, we get decimal codes of 63 and 16, rather than 1087.

Please review the spreadsheet and tell me if I have got it right.
It appears you got it right. As my post below/above will show, we just shifted bits around and limited the Device to 5 bits. I'm OK if you guys don't want to support this new format. If both of you had not seen the webpage, I wanted to point out its existence as I have a complete codeset so that I can test whether apple adds support for any new codes.
