JP1 Remotes

You can use any buttons you like, just write in the "Notes" box what each button is.

I've added all the missing buttons except for the mouse and pad buttons as those will require a new executor.

Here's the KM file...

And the RM file...

If you understand what they do, could you give a better description of the four "pic" buttons and the extra "left arrow" button. I'm also curious what buttons like E and START do.

According to the manual

First row color buttons
My Tv, My Music, My Pictures, My Videos

Next row
Record TV, Guide, Live TV, DVD Menu
All the above are mapped to different keyboard keys, or key combination

e starts the default web browser
Power sleep computer (does not work)
Left Arrow- Backspace
i- Information (does not work)
start- open MCE application (mapped to Alt-Ctrl-Enter)

Thanks, I'll update the files with those descriptions. Do you think you'll need the mouse or pad buttons at any point? If so, I'd like to see a new set of learns from them just to be sure that what I'm seeing is consistent (these signals have a different format to the others). If you could, could you also verify that the learns work.

I plan to check all learns once I update my 6131n. I do not really plan to use the mouse buttons given that it I am using a universal remote with limited number of buttons. The mouse functionality has so many buttons it would be a challenge to use it with another remote. I may just need the left and right mouse buttons.

On another topic, I am looking for a replacement for one of my 6131n remotes, I need one with the same, or smaller, size, at least 3 devices with JP1 interface. I am considering URC-6960 you have on sale, I am just wondering if it is similar in size to 6131n.

Also, if you have suggestions for a small (3-4 devices) JP1 remote available for sale, I would really appreciate it.

Finally, I want to thank you for your help. I am wondering if you accept donations, I could not find anything on the web site.

What I meant by "checking the learns" is, once you've learned the buttons from the OEM remote, test them right away to verify that you've captured enough of the signal to make it work.

The latest batch of learns were a lot harder to decode than the earlier batches. This was further complicated by the fact that the mouse and pad buttons use a slightly different format. Plus, the data for some of the pad buttons changes mid-way through and then changes back. I suspect that this is because your finger moved slightly causing the pad to send the signal for a slightly different "direction" but I would need to see a 2nd set of learns to be sure.

As for using the pad buttons, there are tricks available using JP1 that could facilitate that. For example, you could create a 2nd upgrade where the arrow buttons are programmed with the pad controls, and all the buttons around the arrow buttons could be the diagonal pad buttons. Then, you could use the Device Multiplexor to switch between the two upgrades. You could program the L1 button to switch to pad mode and the L2 button to switch back, for example. Or, being a bit more creative, maybe the MENU button would switch to pad mode and the EXIT button would switch back. Pick whatever seems the most intuitive to you.

As for getting a new remote, are you really looking for another 6131n if one were available? If so, I can check to see if I have any more. I doubt that the URC-6960 is really what you're looking for as it's a Kameleon remote. The URC-8820 is also exactly the same size as the URC-6131n, but it's a JP1.2 remote, so it would need a separate cable.

I don't solicit for donations, but I'm happy to accept them, just use one of my regular Paypal accounts (as listed in my "for sale" thread).

Sorry for the delay, been busy at work. I already have a 6131n which works fine. However, I am looking for a replacement that might be smaller but still JP1 programmable as I only need 3 devices for my setup. I only use URC-8910 for learning purposes, it is too bulky for daily use.

I was considering URC-6960 as an alternative since I never used a Kameleon remote and I read good reviews about it and it is JP1 compatible. Otherwise I can just stick with my 6131n.

Just sent you a little thank you.

Much appreciated.

As for a new remote, the best I can think of would be the old version of the 6131, it's not as long as the 6131n, but it's a little chubbier, which I think makes it sit in your hand better. If you want one, let me know, as I may still have some more somewhere.

As you didn't give your description of this protocol, I've followed your very helpful instructions here. I see why you wanted those new buttons in the Learning tab! It seems that this is yet another variant of the TDC protocol. I've called it OrtekMCE as there is already an MCE protocol that is the official Microsoft one. This remote seems to work with its own plug-in USB receiver, and presumably its own software. I've decoded it as

OrtekMCEn {38.6k,480,msb}<-1,1|1,-1>(4,-1,D:5,S:5,F:6,C:1,^48m)+

where as before, n is XOR of C with right-most bit of F. I've split the fixed data this time into a 5-bit device code and a 5-bit subdevice code, as only 5 bits appear to be fixed throughout all the signals. Zaldwaik's data seems to decode OK but I can make neither head nor tails of the result. You commented on the signals having three parts, but I expected to see something more systematic that I found, which is:

The Robman · Posted: Fri Jul 24, 2009 11:39 am Post subject:

Here's what I determined from looking at the signals.

The freq is 38.6 kHz
The round-to number is 500
The leadin is +2000 -500
The leadout is 48,500
A ONE pair is +500 -500
A ZERO pair is -500 +500

There are 17 bits of data and the signal is sent in three parts:
There is a "first time" string, followed by a repeating string, followed by a final string sent when the button is released.

The executor that I wrote treats the first 7 bits as fixed, followed by 10 variable bits, which are split into a 6-bit byte and a 4-bit byte. The last 2 bits of the 7 "fixed" bits are different in each of the three parts, but the changes are the same each time, so the assembler code handles this. The 6-bit portion of the variable data remains the same in each of the 3 parts, but the 4-bit portion changes between the 1st and 2nd parts (the 3rd part is the same as the 2nd), so nibble-1 of the 2nd variable byte is the first 4-bit pattern, and nibble-2 is the 2nd, then in the assembler, I swap them between the 1st and 2nd send.

I didn't notice any patterns in the data, so I can't really tell is the data is LSB or MSB and I couldn't tell if the data is encrypted or if there's a checksum, but to be honest I don't think I spent much time looking.

Here's the data in a spreadsheet:

I am assuming that the missing parts are due to errors in the learning rather than the signal should be that way.

As for getting the 2nd byte when the first part is missing, if you look at all of the signals as a whole, you'll notice that there are just five possible values for the 2nd byte, those being:

1E
2C
6A
A2
E6

Now, let's look at the 2nd byte for the two signals where the first part was missing:

_6
_A

Based on the 5 byte2 values posted above, _6 should be E6 and _A should be 6A.

What I meant by not noticing a pattern was that I wasn't able to figure out if the protocol is MSB or LSB, I wasn't able to determine the true OBC and I wasn't able to figure out if the signal is encrypted (in a "Lutron" fashion") or if there's a checksum in there.
