JP1 Remotes

I recently bought a Digital Cable Receiver from Samsung, which is quite new.
I didn't find a device upgrade for it, so I decided to make one myself.

However when I open the learned data tab in IR I don't recognize the protocol. It has more than one line and the protocol is eg Gap-502-1150-16?

I searched the forum for this Gap protocol but I only found device specific information. These protocols don't work for my device.

I learned as much keys as possible until the memory was full.

My remote is an URC8910 and I use IR V7b3

Link to my IR file------>

Hope someone can help me out.

Marcus.

We've certainly seen those signals before (16 bits then a large burst then 20 more bits). But I don't know what to search for to find the previous thread.

Hopefully Rob has a better memory of this than I have.

Hopefully Rob provided an upgrade last time that can be used this time.

I found this thread when searching for the gap protocol.
I've tried the protocol but it doesn't work for my device.

Should it work in your opinion or do I need a different protocol Question

It may need different values plugged in, I don't have time to look at it now myself, but if you want to look at it, use the signal structure that I described in that other thread to decode (by hand) the signals that you captured.

Ignore the "Gap" stuff, just use the raw timing data. To view the timing data select Advanced > Forced Learned Timings

Ok Rob, thanks so far.

That sounds pretty advanced to me though, but I'll read through the other thread and see what I can find out.
Until now I only have build simple KM files.

If you could find the time I would appreciate it off course.

Regards, Marcus.

Here's how you decode signals. First you cut & paste all the learned times over to Notepad (or similar). Here's just the first one from your file...

Great work, thanks a lot Rob.

I'll try your file and maybe with the info you supplied I'd be able to decode the rest myself.

Marcus.

When you're done, please post the updated info here and load the upgrade file into the file section (then I'll delete the file that I created).

Ok Rob,

Hate to bother you again, but I've loaded the device into the remote and unfortunately none of the signals work Crying or Very sad

Do you have any suggestions at this point Question

Regards,

Marcus.

Well, the first step is to eliminate "user error", so to that end, could you please load your IR file into the Diagnosis Area (and post a link to it) so I can take a look.

While you're at it, if you have the function names for the signals that you learned previously, please post them, and if you've learned the rest of the buttons, please post that IR file also.

Ok Rob,

I've uploaded your KM file updated with the button functions and also included my IR file with the device loaded as cable/2000 and some more buttons in the learned data tab with button info in the note section.

Here's the link

I see what you need to do, change the "Raw Fixed Data" cell (in KM's Setup sheet) from 00 to 40.

Yeah, that's it Very Happy

Now I put the OBC's of the remaining buttons of the remote in the KM file, but I guess that's just too simple... Wink

Unfortunately that doesn't do the trick.

I,ve uploaded the KM file tothe files section, so maybe you can take a look at it Rob. I guess I need to convert these signals and cannot just use the OBC Question

The non working functions start at cell 23 in the KM file
