These are very long signals and it looks like you are not capturing enough of the signal. Do you have a way of creating a learned signal using Pronto hex? If so, try entering the following hex for the OFF command:

0000 006E 00DB 0001 0080 0041 000F 0031 000F 0011 000F 0011 000F 0011 000F 0031 000F 0011 000F 0011 000F 0011 000F 0011 000F 0031 000F 0011 000F 0031 000F 0031 000F 0011 000F 0031 000F 0031 000F 0031 000F 0031 000F 0031 000F 0011 000F 0011 000F 0031 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0031 000F 0031 000F 0031 000F 0031 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0031 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0456 0080 0041 000F 0031 000F 0011 000F 0011 000F 0011 000F 0031 000F 0011 000F 0011 000F 0011 000F 0011 000F 0031 000F 0011 000F 0031 000F 0031 000F 0011 000F 0031 000F 0031 000F 0031 000F 0031 000F 0031 000F 0011 000F 0011 000F 0031 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0031 000F 0011 000F 0011 000F 0011 000F 0011 000F 0031 000F 0011 000F 0031 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0031 000F 0031 000F 0031 000F 0031 000F 0011 000F 0031 000F 0011 000F 0031 000F 0031 000F 0031 000F 0031 000F 0031 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0031 000F 0031 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0011 000F 0031 000F 0031 000F 0031 000F 0031 000F 0031 000F 0E98

Thanks for helping me.
The USB-UIRT Learn helper does not recognize the string you sent me as a valid IR code - therefore the 'Test transmit Ir code' button is disable. Tried to delete some lines form it - no scuccess. I am using lrnhelper version 0.5.0. Maybe is there another program that can sent IR using USB-UIRT ?
Regards,

It is a valid signal, it's just very long. I'm guessing that your device simply can't handle a signal this complicated.

In the past couple days I tried to find more info about my device (why can't transmit the code you post) without luck.
In order to solve this as quickly as possible, can you recommand me another device I can buy ? I have the following requirements:
1. Learn/send IR
2. integrate with Homeseer
3. Output for external Ir eye.
4. Be able to lean/send long codes like you postad.

Thank you.

You could also consider getting a new A/C. Smile

No way . . . I went through a very paintfull instalation process (cutting walls, painting, dirt and dust inside) and of course the extra cost for having only one external unit.
The IR devices that meet my requirements are so rare ?

Another ideea: I have 5 (five) remotes to control the A/C. Is it not possible to dissassamble one of them to modify it somehow (like take pieces out of it and install them in the USB-UIRT device) ?
Sorry in advance if the ideea sound silly but I am new to this and I MUST solve this somehow.
What IR reader do you use to get the whole code correct from the remote ?

The Robman · Posted: Tue Aug 24, 2010 10:18 am Post subject:

Modifying the remote won't do anything, you would need to modify the A/C.

This A/C uses very long signals, so I have to imagine that many IR replicator type devices are going to have a problem replicating this signal.

Welcome to the forum.

What kind of remote are you working with?

Apparently this is a huge signal and most remotes will have trouble with it.

michaelknight · Joined: 02 Oct 2011 Posts: 14 Location: España/Spain

Thank's vickyg2003.

My remote is the same as appears in the PDF manual showed by "The Robman". That's because I thought the codes written by him maybe work whith my project but my osciloscope signal doesn't match with his description or perhaps I don't do the right interpretation. My split is FTXS25CVMB.

I don't know if I can give anymore useful information.

Rob is working from the timings reported in the homezn.txt created from some pronto learns

This is obviously a very different signal than your screen shot is working from.

If you look at Rob's analysis you'll see that the frequency is 37.7kHz or 37,700 Hz very different than the 482.000 Hz shown in your osciloscope shot. And then the timings are so different as well. We are showing
timings in microsecond [µs].
ONE pair: +425 -1300 µs
ZERO pair: +425 -440 µs

Your screen shot says the time on the line are set to 2.075 miliseconds or 2000 micro seconds so on your screen shot. I'm not sure if that means the ticks are 2000 or if the total time is 2000ms. Assuming its the tick size then
ONE PAIR = +2000 - 6225 µs
ZERO pair = + 2000 - 2000 µs

Otherwise the timings are much smaller, either way, they don't match what we are seeing.

As you can see a much different signal.

However you analyze your signal, you are going to need a longer sample time because these signals are very long. They are also dynamic, as they have all sorts of information encoded in the signal.

PS: you can download IRScope to see what the signals we are using look like. You can paste the pronto hex into a window, and the osciloscope will pop up and show you what our signals look like. Keep in mind that our signals will be upside down from yours because our "on" times go up while your "on" times go down. At least I assumed your on-times go down as I've seen similar screen shots before.

Well, there are some details to get clear because in my screenshot aren't so.

About the frequency don't take so much care. My software doesn't measure the right value when the signal isn't regular. In fact, that fequency changes when I select a piece of the line to know how many time it takes.

The signal it's realy longer than I showed but if I sample the full signal it appears so small and illegible. What it's shown in the shot is just the beginning.

Maybe it takes sense if we read from right to left the binary code written by The Robman:

OFF
1000100001011011111001000000000000000000000000100001010000000000111101011111
0000000000000000000000000000000000000000000000000011000000000000000000011111

If you see, there is a long peak seted as 1 which takes 5 bits. Whatching my signal it has some resemblance whith the his ones end.

In this momment everything is so messy I hope to have time enought tonight to study this info.

Thank's.

I tried to download the IR profiles from each of the models listed in the instruction manual which Rob linked. Although each of them had a match on the Logitech Harmony Database, only two of the six models had actual IR commands attached to their profile. So, I don't know if it helps anyone but here are the respective ICT files from IR Scope.

Thanks Earl.

The FTKS-20CVMB ICT was a simple Nec1 signal.
The FTX-S35CVMB ICT was a 56 bit protocol, ours is much longer, but I took a closer look anyway, and the zero timings are not a 1-to-1 ratio, but rather a 1-to-2 ratio, so its definately not the protocol we are seeing nor the one that MichaelKnight (isn't that the Knight Rider) posted.
