Hello,

I need some help converting the Yamaha nec codes to pronto hex.

I found the web conversion toll which can convert some of them but not all.

7E-7E - Power On Converts fine into:

0000 006D 0022 0002 0155 00AA 0015 0015 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0015 0015 0040 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0040 0015 0015 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0015 0015 0040 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0040 0015 05ED 0155 0055 0015 0E47

But when I try to convert: 7A-007F - System Memory 1 Main it converts the same as me doing 7A 00


Anyone know what I should do.

Thanks, Dan

There was a recent thread on that same question. I don't have time right now to search, but you should be able to find it.

For what remote do you want these codes? I'm asking because there is a short "900A" form for Pronto Hex that is understood by actual Prontos and is easier to create from the Yamaha documented form than the full "0000" form of Pronto Hex. But if you need Pronto Hex for a non Pronto, you'll need the full "0000" form.

It's a TSU-9400 Remote

I did what seemed to be the obvious forum search on this question and the first hit was the right one:

For a TSU9400 you don't need the complicated conversion, you should be able to use the short form Pronto Hex from that post:

900A 006D 0000 0001 7A85 007F

I also just now tried the converter from that thread with 7A 007F and it generated

0000 006D 0022 0002 0155 00AA 0015 0015 0015 0040 0015 0015 0015 0040 0015 0040 0015 0040 0015 0040 0015 0015 0015 0040 0015 0015 0015 0040 0015 0015 0015 0015 0015 0015 0015 0015 0015 0040 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0015 0015 05ED 0155 0055 0015 0E47

Which I ran through my decoder and verified it is the same signal as

900A 006D 0000 0001 7A85 007F

If those or any other special codes from Jason's post #6 in that thread work, that would confirm what I'm nearly sure of already, that my guesses in post #2 of that thread were wrong. I think post #8 of that thread already confirms that Jason is correct, but I wasn't certain.

Thanks for you fast replies.

How does the long hex codes equate to the short one?

Thanks, Dan

For some Pronto models there is a translator inside the firmware from that short form to that long form. For other models there is a translator in ProntoEdit.

For models with the firmware translator, you save some memory inside the remote using the short form. But mainly using the short form is a matter of convenience in the UI.

The "900A 006D 0000 0001" at the beginning of the short form mainly selects the specific translator. That translator then does the same translation as that html program Jason linked in the other thread. Except the Pronto translator doesn't know the rules for translating from less than eight digits:

The rules are a missing pair of digits have the value of FF minus the other pair in the same group of four digits.

So 7A 007F is the same as 7A85 007F because FF minus 7A is 85 (you can do that subtract in Windows calculator in view/scientific/hex mode if you don't do hex math in your head).

Similarly 7E 7E is the same as 7E81 7E81.

Thanks for the explanation..

I think i understand ;)

I stick to the long numbers for the 9400 then.
