Hi All

I've learnt all the codes i need for my tilevison, and now they have sent me the discrete codes for on/off and sources. but i'm unsure where to go from here.

The codes are below, i need them in CCF format.

Any help please

Thnx's in advance

Mr P
.

So you have Pronto Hex for ordinary learned signals of that device. Please post a few samples. Digit keys may make the best samples, because comparing Pronto Hex for two digit keys usually answers questions about the polarity and sequence rules of the whole signal set.


Like most manufacturers, they documented incomplete information for IR codes. They provided the details that distinguish one signal from another, but not the basic info that is common to all signals. So that basic info must come from learning and decoding ordinary signals.

Did they happen to include any ordinary signals in the code set they documented? If the protocol is tricky, the very easiest way to fill in the blanks in the documentation is to compare the documented form of a signal to the Pronto Hex of the same signal. Then that info can be used to translate the rest of the documented signals to Pronto Hex.

But even if you don't have any signal in common between the learned set and the documented set, I probably can deduce enough from a few learned signals to know how to translate the documented ones.

Also, are you sure the discrete codes they documented represent IR signals? Many TV's have documented discrete codes only for rs232 signals and have no discrete IR signals.

John

Thanks for replying so quick.

The signals you posted are RC5 protocol but at 38.4KHz instead of the usual 36KHz. I'm glad you posted the extra info, because learning often gets the wrong frequency, even as wrong as 36KHz to 38.4KHz.

I generated the above signals at 38KHz. No IR device actually cares about the difference between 38 and 38.4. It might care about the difference between ordinary RC5 at 36KHz and this device's RC5 at 38KHz.


I'm not sure, but I think that means it barely cares about frequency errors as big as 3.8, so it should work well all the way from 34.2KHz up to 41.8KHz.

Depending on the model of Pronto you have, you might get significantly better behavior from digits and maybe a few other functions if the Pronto is programmed to specifically know the signal is RC5 rather than using learned signals. But for discrete codes that isn't a consideration.

So the Pronto Hex I posted should be OK for discrete codes, but signals you already learned may work better (especially in macros) if you program them in ProntoEdit selecting RC5 protocol, System 0, and the correct command data for each signal. Your digits 1 to 3 have command data 6, 7 and 8. Power toggle is 5. Digits 4 to 9 probably have command data values 9 to 14. Digit 0 might be 15, but that is barely more than a guess.

If you program them that way, they would be at 36KHz instead of the learned frequency of 38.4, but I think that won't matter, while having the Pronto know it is RC5 (rather than a pure learned signal may matter).

See if a macro can tune channel 11 (or 22 or 33, etc.). If there is a problem doing so, that would be a symptom of the problems caused by using learned signals instead of having the Pronto know it is RC5.

Thanks very much John, i had no idea where to start at all.

Will test and let you know tomorrow. Had enough at the mo :-)

Hi John

No joy, with the commands John. but i think they have supplied me with duff info. Got a load more info from the manufacturer today. Will this help?

It took me a while to figure out what they mean by that. I think I have it. I put it in the above Pronto Hex strings.


What was that supposed to be? That is in the same code set as xbox360 signals but isn't any of the xbox360 signals I have in my large library of IR signals. Why did you include it in your post?


I'm not sure what you're asking or telling me about those signals. They are very closely related to your signals, but the function names don't match. If I understand everything in this thread so far, and if you have an actual Pronto (rather than some other device that uses Pronto Hex) then many of those signals will operate functions of your device. They just won't operate the functions associated with them in that list (for example I thing num6 to num8 from that list are num1 to num3 of your TV).

What I said earlier about making your digit functions work better could be done by replacing them with that type of short Pronto Hex. I think these should work for the digits 1 to 9:

Hi John
This is what the manufacturer sent me, i was also confused about the email as well, everything in my post was what was sent from tilevision. It was a very confusing email that didn't gel very well.

I'll try what you sent, thanks very much. I'll put them into my pronto and test.

Cheers

Mr P

Thanks johnsfine you've done great work getting this far. The discrete on works perfectly but unfortunately the discrete off doesn't. Have you got any idea why this is?

Sorry. "doesn't work" almost never provides enough new information for making a new answer.

Without a larger amount of new information I have no basis for guessing another answer.

I don't have any similar device myself, I just guessed at the meaning of the manufacturer info quoted by the OP, then translated that guess to Pronto Hex.

Understood, and apologies for the ambiguity of my statement. This product has been a major pain in the ass for us and despite several phone calls and emails I have only been able to get the same info as MrPUK.

By doesn't work I mean that the LED flashes to indicate a command has been received but there is no response. I appreciate that with the information you have available that is of little help though.

Thanks so much for your input anyway. At least with the discrete on we can apply some logic to the programming to simulate a discrete off.

should have bought an aquavision

since you answer constantly I'm writing to you or anyone else on the
site that "might" know something about this. I have an Advent 23725A TV here
With a Phiilip UNIVERSAL (CLO19) remote that was just working before switching the batteries out.

I'm Looking for both the code for the TV "AND" how to input it on this old remote again, as I No longer have the manual, but thus far, have found NOTHING anywhere.
