Is it even possible?
According to this documment: [Link: proaudioinc.com]
Some of the rs232 codes are very similar to short hex codes.

For example
RS232 Key Aspect Ratio (4:3) mc 01 76(CR) 6D 63 20 30 31 20 37 36 0D
IR HEX 4:3 (ASPECT RATIO) 32-BIT DATA 04FB 7689.

There is a shared component "76"

What I'm desperately trying to do is to find discrete hex codes for switching between Picture Modes on my TV: vivid, standard, cinema, game, user, etc. I'll be much obliged for any help.

THAT my friend, is a GOLD mine. I've never seen that document before, and hell if I know if you should be linking it, but it's certainly a keeper.

I mean they give you full IR codes, Hex codes, pronto ccf codes, carrier frequency, a diagram of the IR in action, and the NEC code set for generating codes. That is literally THE master list. And short code? amazing!

The code you are looking for are on pg 20 of the whole sheet or page 4 of the generic IR section. The formatting of the pronto long code is silly, probably a pdf formatting issue, but they also give you the short code to verify. I checked both with IR scrutinzer.

Because I wasn't sure on the long code, I used [Link: awe-europe.com] We know, according to the document, that this is standard NEC 1 IR code, and can likely use the yamaha generator which is also standard NEC 1. We reference the short code in the document for 4:3 "04FB 7689" (use a space instead of the dash).

We take the generated code, dump into IRScrutinzer to verify it against the pronto long hex in the document and come up with the same.

Protocol=NEC1 Device=4 obc=118.

You are welcome.
Unfortunately the codes I'm looking for aren't there. I need picture (processing) modes, not screen ratio modes. They are on page 37 (section 21) in RS232 but I need them in IR format.

I misread your post, or the codes you are looking for are not clear. No I think I see what codes you need. While there appear to be discretes for RS232, there is a toggle for IR. Why aren't you using that?


There is the AVMode. There is the EZPicure. There is X-Studio.

Are these codes not working for you?

Or are you looking for codes to take you disceretely from "warm" to "cool" without having to toggle through it? I can't think of a single reason you couldn't walk your client or yourself through how to toggle through the varieties and would need a discrete for this.
