I don't understand how Peter convert 11 to 11EE
and 5A to 5AA5.
Using the Windows calculator program:
1) In the view menu, select scientific.
2) Click the Hex button
3) Type FF-11=
4) Read the display, which says EE.
If you don't have Windows, you'll need to find some other hex calculator (program or actual calculator) to subtract each hex code from FF.
To make the last four digits of any of these "900A" type signals, you use the two digit hex code of the command followed by the two digits you get by subtracting those first two from FF.
And the first part of code (900A 006D 0000 0001
04FB), stay it the same in the different code
?
That should stay the same for all commands of that device. For some other device that part would be totally different.
Some devices have more differences from one command to another than just that last part. But the many devices that use commands beginning
900A 006D 0000 0001 04FB
don't vary more than that last part.
