Hello,

I am from France and I have a problem. I bought a plasma LG and in the manual there are discret codes in Hexa such BF, C6, D5, D6...

How convert this code to use it with the pronto remote.

in manual , hexa code for AV1 = 5AH !!!!!!
an original learned code is button 1 = 900A 006D 0000 0001 04FB 11EE in manual write button 1 = 11H

and Peter Dewilt answered

11H means 11 Hex

The last word for button 1 is 11EE so presumably that is where the 11 comes from.

The two halves of the last word (in this case 11EE) must add up to FF (i.e. 11 + EE = FF)

So the full code for 5A Hex is

900A 006D 0000 0001 04FB 5AA5

I don't understand how Peter convert 11 to 11EE and 5A to 5AA5.

And the first part of code (900A 006D 0000 0001 04FB), stay it the same in the different code ?

Thnak you for your answer

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.


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.

Thank you for your answer.

I try it this afternoon

Chris
