I have taken the codes from that last page at RC and broken them down in the following spreadsheet. 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 ...

Incorrect bit order

The bit ordering they state on that site is truly incorrect. I've tested the codes generated with an IP file that uses a fixed subdevice.

I would vote for the Command Page approach.

Personally, I know the Wikipedia page does not list all the command pages but for sure 0 is the Pair Command Page, and 5 is the one we know as Device 229. However, the undocumented one (14) with Home and Play/Pause which we know as Device 238 also exists.

But I do defer to you guys and am happy ...
