I have seen talk of issues with the Denon-k documentation and I am wondering if what I am seeing is just that.

Upon examination of Denons Kaseikyo documentation for the 3806 and 5805 I noticed that the Main Zone User-1 -2 and -3 parity column 41 differs from that of the same commands in the 2807 and 4306 documentation. I also notice a similar difference with several other commands. Unfortunately the function numbers are not listed on the 3806 and 5805 documentation as they are on the others so I am not sure if I am comparing apples to apples here. Typo or different codes? Which is correct? Is anyone aware of any other?

Here are a few examples (differences are only in the data and final parity columns)

"Scale"
4306: (data) 010011110100 (parity) 01110010
5805: (data) 000011110100 (parity) 11110100

"Zone 2 Mute"
4306: (data) 010011101000 (parity) 00101110
5805: (data) 010011101000 (parity) 11101000

I would appreciate any insight.

Thanks, Troy

I have seen a lot of Denon's Kaseikyo documentation in which the parity columns are total garbage (errors in every line). I've stopped looking at the parity columns.

If the Genre and Data sections are the same, it's the same command. If the parity columns differ on the same command, at least one of them is wrong. But more likely both of them are wrong.

But for your Scale command there seems to be a diffence in the data section. I don't have any Denon device, so I can't test, so I have no guess whether the data section of the documentation is accurate. Maybe that command differs across models. Maybe it is a typo.

The Denon-K.irp file has the correct rules for computing parity.

The 5805 pdf lists the command you show (which is function number 752) with the name "Main Zone Scale"

The 4306 pdf list the command you show as function 754 (which is shown consistently in decimal and binary) with the name "Scale (for HDMI Monitor)".

Assuming those are the same command, I wouldn't guess a typo in the 4306 pdf because the decimal is consistent with the binary. As I said before I have no basis for guessing whether it is a typo in the 5806 pdf.

Would you mind guiding me through the process of determining the function number so that I may reference these for my self down the road? I assume that this is determined in the Data columns.

Thanks

Not the way I do it, but:

Start windows calculator in view/scientific mode.
Click on the bin button.
Type the data value backwards (you can skip the originally rightmost 0's) For example Scale 000011110100 would be typed as 1011110000
Click the Dec button.

Thanks again!!!

What do you do when you are not educating the rest of us?

Regarding the Denon-k .irp file.....

Is there any particular reason that the function range is set to 753 maximum?

Some of the Denon functions are listed above 753.

Can I just edit the .irp file to extend the range?

Is there a maximum range based on the mathmatical possibilities?

Thanks
