Decode Graetz DVD model AV690 (from winLirc)

[yarix]

Hi Everyone,
I have a Force RC that I got from the cables company in Israel. the remote have a JP1 connector and I'm able to communicate with the computer.

In the last 3 days, I've been trying to create teach the remote how to control my DVD player "Greatz AV690".

I've captured many some signals of the DVD remote with WinLirc:

Code: Select all

end remote

my question is: Do you recognize this code? does anyone have an upgrade file for that remote?

Additional information that I have is from the "learned signals" tab in IR.exe:
for example for the "Play" learned signal I get this:
Protocol: NEC1
Device: 0
SubDevice:
OBC: 87
Hex Cmd: 15
EFC: 106
Misc:

I hope the information is enough to "hack" the codes for the DVD.

Thank you very much!!

I noticed that the HexCmd in IR.exe is the first 2 digits form the winlirc codes.
for example play\prev in winLirc :

Code: Select all

Play   0x00000000000015EA 
Prev   0x000000000000857A 

and the play\prev in IR.exe "learned signals":

Code: Select all

Protocol |  Device | SubDevice | OBC | Hex Cmd  | EFC
NEC1     |   0     |           | 87  |  15      | 106
NEC1     |   0     |           | 94  |  85      | 230

notice that the hex code is the same for play=15, and prev=85. it's the same for all other buttons.
how do i get the OBC and EFC codes? what are they?

BTW in another session of learning, most of the learned signals did not had a protocol line at all, few had protocols like that:

Code: Select all

Protocol         |  Device | SubDevice | OBC | Hex Cmd | EFC | Misc
Gap-550-1357-28? |   240   |   63      | 188 |         |     | F0.3F.C4.B

You don't need LIRC, nor any of that Frequency and Raw data from IR. If you have a JP1 cable (it appears that you do) and IR.exe (it also appears that you do), you have all you need in your hands.

Have you read the JP1 for beginner's sticky posts? (linked in my sig below)

The decode data (NEC 1, Device 0, and OBC values) is all you need to build your own upgrade using either Keymap Master or RemoteMaster.

Read the readme's, pick your program and then come back with specific questions if you still have trouble.

The Gap decodes indicate that one or both of your batteries are getting low. The consistent NEC decodes are correct.

[johnsfine]

I noticed that the HexCmd in IR.exe is the first 2 digits form the winlirc codes.

That is not a general rule for LIRC. But for a specific device, once LIRC sets it up that way, that will be true for the rest of the functions.

how do i get the OBC and EFC codes?

If you use (RM) RemoteMaster to create the upgrade (rather than KM) you can type in any one of HexCmd, EFC or OBC and RM will compute the other two. So that LIRC data (for each button) plus the decode info of NEC1 protocol, device 0 (from any one correctly learned button) is enough to build an upgrade.

The Gap decodes indicate that one or both of your batteries are getting low. The consistent NEC decodes are correct.

I don't think that Gap decode would occur from low batteries. More likely it is from moving the remote as you press the button to be learned. But anyway it is a bad learn. If you didn't have the LIRC data to use instead, you would need to redo the learns for any buttons for which you don't have an NEC decode.

Thank you for the quick response, by the time I notice the response I created a map between Lirc and IR learned signals.
So actually my remote controls the DVD (Greatz AV690), but I'd like to do an upgrade.

I will try to create upgrade from that, and post it here, if it works....

Thanks johnsfine, Capn Trips.

I've completed the upgrade of the remote. i Used the KM excel.

is there a file that I should upload for other people with such problematic DVD?
I guess that with the above table everyone can create an upgrade...

[Capn Trips]

You should upload your KM file to the appropriate area of the File Section>Device upgrade files>DVD (linked near the top of this page).
