I'd appreciate Hex IR code ON and OFF for Yamaha Blu-Ray BDA1010 or BDA1000

Both should be:

Thanks. I will try in the a m.

Be sure to let us know which one or if both work. It'll help the next person that need it.

The second poster's Hex Codes worked. Thanks to both of you. Is there a way that you figure these out? IF the method is posted somewhere, let me know.

Thanks Again!

Me or 2nd set posted by 3FG?

One way is to get the NEC IR codes from Yamaha that are for all commands and discretes and then use the converter located at the link below to convert the ones you need to hex.

where did you get the codes?

One way to get the original data is to use [Link: awe-europe.com].  The BDS1067 are the newest Blu-Ray codes they have.  The upgrades section at hifi-remote.com also has Yamaha Blu-rays, and those can be read using RemoteMaster.

The Yamaha converter has to be used carefully.  In this case the Yamaha documentation tells us that Power On is Custom code 7C and Data0 is F6.  That's actually short hand for Custom code 7C83 and Data F609, where 7C and 83 are the binary complement of each other, as is F6 and 09.  The Yamaha spreadsheet displays the 09 in greyed out font.

The correct entries into the Yamaha converter are either 7C F6 or 7C F609 or 7C83 F6 or 7C83 F609, where the space distinguishes the custom code (usually called the device number) from the data (usually termed the function number or OBC). Evidently whoever generated the codes hdtvlvr has posted instead entered 7CF6 09, which produced device 124.246 with OBC 9.

I like to use the import function in IRScope to check Pronto Hex, because it can show the waferform graphically, and export clean versions of learned Pronto Hex.  There is a newer version of DecodeIR.dll (2.43) available, and you should download that also.

Inputting the 4 options you gave into the converter here ([Link: hifi-remote.com]) give identical results to what I originally posted. Not sure why the original code didn't work. Do you get something different for each?

The four Pronto Hex are all the same as each other, but are different from the first hex you posted in this thread. Power On, from Post 2:

As I said in the last sentence of paragraph 3 of post 10, the Hex in Post 2 decodes to 124.246 (7CF6)  device 9.

Post 11 decodes as 124.131 (7C83) device 246  (F609).

So many 0015's, I missed that. Thanks.

Ok, we both agree that the NEC code is 7C F6 and the code in post 11 should be correct, so why is the conversion in my post 11 different than yours?

I'm trying to understand and learn too. Thanks

Well, my first reaction was: "but they're not different!" Actually. there is a small difference, and I'll get to that later, but I suspect that a little explanation of Pronto Hex is in order. The main thing to understand is that Pronto Hex is not a code, but just measured times. So small differences aren't important.

The first 4 quads of the Hex mean:
0000 This is Raw format with modulated IR burst pairs
006D The frequency of modulation = 4,145,000/109=38KHz [6D in hexadecimal format is equivalent to 109 decimal]
0022 This hex signal has 34 (decimal) burst pairs that are sent once
0002 It has 2 burst pairs that are sent to repeat the signal

The remaining quads are the durations of the burst pairs, in units of the modulation period (1/38000 = 26microseconds). The on duration is first, followed by the off duration. So 0015 or 0016 (21 or 22 decimal) are almost the same time, differing by only about 5%.

Similarly 006C or 006D (108 or 109) are nearly the same frequency.  The actual NEC1 frequency would fall between these two integer numbers, so either is as correct as can be specified using the Pronto Hex format.  Moreover, 006C is the larger frequency, so the modulation period is slightly shorter, and the burst pairs need to have slightly larger numbers to get about the same duration.

So the only noticeable difference between post 11 and post 3 is the 5th from last quad 0699 versus 05ED. That is the so called lead out time-- the time between repeats of the signal. It is seldom very important. I didn't use the Yamaha converter; instead I used IrMaster.  MakeHex is also used frequently.  We know the specification for NEC1 signals, because NEC published them.  IrMaster gives 0699 using 006C as the frequency (lead out is thus 44mSec), while MakeHex give 0689 using 006D as the frequency (also 44mSec).  These are the correct durations according to the spec.

The Yamaha converter provides 40mSec of leadout, and is incorrect in that detail, but it will probably never affect anybody.

ETA: I had this backwards. 40mSec is the correct leadout and the Yamaha converter is correct, and the other two are off by 10%. Still not important. The actual NEC spec is 108mSec for total frame duration, and so the leadout will vary if the device and subdevice aren't binary complements.
