Hello,
Excuse-me for my "bad" english.
I have a multimedia HD and when I learn code for the remote with TSU300, most of the key have an alternate code, so I can't press 2 times the same key.
I used IRTools and I saw that the protocol was RC5 (device 15) which can do the alternation.

But I don't know exactly how to convert my code. Could you help me please ?
Thank you in advance.

Here is 3 examples :
-- Stop/Return --
First press
0000 006C 0000 000B 0020 0020 0041 0020 0020 0041 0020 0020 0020 0020 0020 0020 0041 0041 0041 0041 0020 0020 0020 0020 0020 0CCD
Second press
0000 006C 0000 000B 0020 0020 0020 0020 0041 0041 0020 0020 0020 0020 0020 0020 0041 0041 0041 0041 0020 0020 0020 0020 0020 0CCD

-- OK --

Hello,
just to precise that I want to convert this code for the Pronto (like 5000 ......) to enabled the alternation.

And after several search, I found this (thanks to johnsfine) :
"5000 0000 0000 0001 00wx 00yz
where wx is the device number in hex and yz is the command number in hex."

So this code woud be :
Stop/Return : 5000 006C 0000 0001 000F 0017
OK : 5000 006C 0000 0001 000F 000E
Forward : 5000 006C 0000 0001 000F 000F

Is it correct ? (I can't try until next week-end)

Thank You

Your translation is correct, assuming your model of Pronto understands the form of Pronto Hex beginning "5000".

Hello,
thanks you for your confirmation.

My model is a Pronto NG TSU3000, is it OK ?

Thank you

Yes. (I wondered whether "TSU300" was a typo).

Thank you very much

Hello,
just to confirm that it's OK.

Special RC5 code like 5000 0000 0000 0001 000F 000F (Forward) works perfectly, I can do x4, x8 ... with the same button like the original. And it's works for all the functions, except for Power (so I use the learned code).

I precise that it's for multimedia Jukebox Rapsody RSH-100 (for the Forum Search)

Thank you for all.
