View Full Version : Converting IR codes from one format to another

November 5th, 2005, 03:41 AM
Trying this again. I have a Yamaha RX-V2500 and would like to control it through the UIRT transceiver. The discrete code I am getting from the Yamaha PDF looks like this:

900A 006D 0000 0001 7E81 758A
Yet when I learn a function from the remote itself, I get code that looks like this:

R02EE815480AA1616164016161640164016401640161616401 61616401616161616161616164016161616161616161616161 6164016401640164016401640164016401616161616

When I insert the code provided from the PDF, it doesn't work. It looks like this code needs to be translated. Am I on the right track? If so, does anyone know the process for this conversion? If I'm way off, please let me know.

Hey eric,

That code looks alike like a Pronto type code. You have 2 options.

Just learn the ir code from the remote or contact Jon at support@usbuirt.com he may have a little prog that will convert it.

Good luck

Thanks Leaf,
I already got in touch with Jon and he said -

Sorry, but I do not. These are an undocumented Pronto '9000' format. What
you'll need to do is find (or learn) the codes in Pronto 'Raw' format (which
begins with '0000').

I can't learn them from the remote because they're not remote commands. They're rs-232 commands codes.

Any other ideas?

To be honest you are far better off talking to your Yamaha over RS232 - that way you can get feedback from it.

Yeah, I know. I tried communicating with it through Girder 4.0 with a plugin someone created for a simular Yamaha Model. I was about 90% there, but I had intermittent communication problems. If you know of a way or a plugin I could use with Girder 3.3 that would be great. Right now, I just don't have the time to learn Girder 4.0.

EWW my bad,
In Girder3.3 use the Generic Serial plug in. I use it to control my Denon 2805 Thanks to the peeps that put together the stuff here.. The serial port never gives me problems. There's a Yamaha RXV serial file in downloads section http://www.promixis.com/download.php?ID=263 That should fix ya right up.

I use a program called Make Hex to convert the Device Code (Custom Code) and Function (Data Code) from my pdf to a hex code that I can send from my USB-Uirt.
