Hi, I am new user.
I have used a IR learner called “USB-UIRT (http://www.usbuirt.com/)”
This is very useful.

Here is the brief how to use it.
1.Connect USB-UIRT to my laptop, and install the driver
2.Launch the software called “USB-UIRT Learn Helper Utility”, and press “Learn IR Code” , and press the button of the remote controller toward USB-UIRT
3.IR Code will be shown
4.To test whether the code is learned properly or not, just press “TEST Transmit IR Code”. Then the IR signal will be blasted from the product, and I can make sure.
5.I can paste the IR code(ex, like this website), and test also.

I have learned a lot of IR signals of eclectic devices with this method before.

OK, actually I have trouble to learn Fujitsu Air-conditioner.(A/C)
Judging from conclusion, only “STOP” signal could be learned properly.

But other signals below can not be learned. (see below)
24-HEAT- AUTO,
25-HEAT- AUTO,
etc….

(Degree is different from your site. Because here is using “Celsius” in Japan.)

For example, here is the code which I tried to learn “24-COOL-AUTO”. This is not working.

If I pressed “TEST Transmit IR Code”, nothing happened, although I tried to learn properly.

So I almost give up to learn Fujitsu A/C signal by USB-UIRT.
Then I discovered this website. That’s why I mind to post here.

HOWEVER when I copied codes from this site, it works with some of Codes!!
NOT ALL. The code which it works with is, Posts 21(above), Post 24

Would someone advice me what’s the difference between the code which works with and other codes?

Sorry , I am not native English speaker. So I am happy if you could advice me as easily as possible you can.
