JP1 Remotes

[tase2]

I ordered the completed cable from Hovis.

I'm sure I will be asking for help when it arrives.


Thanks

Mark,

This may help get you started on the quest for CC discrete commands.

The Panasonic Protocol consists of 48 bits of data consisting of six 8-bit bytes. To date, the first two never change; the next two are device and sub-device; then function (usually called OBC here); and finally a check byte, that is derived from a mathematical relationship of the previous three bytes. (The good news is that the built in Panasonic protocol already does this for you)

Device never changes for Panasonic displays (TV's, HDTV's Plasma's, Projectors) and is decimal 128. Sub-device for most display commands is 0. This is described as 128.0, but by convention we also call 128.0 just 128, (but 128.4 would always be called 128.4) Panasonic:128.0 is setup code TV_0250 in most every OFA remote.

For Panasonic Displays, you can generate all possible OBC's for 128.0 by several methods and test them. Panasonic is fairly logical about its numbering scheme for commands. Here is the list of all the commands that I know of for 128.0. This is a composite of several different libraries and decoding a bunch of ccf files. Not all commands will work for any specific display.

The reason for long explanation is that in addition to brute force testing all 256 commands, there is a methodical approach based on the tight grouping of similar commands. (Note: Power Toggle=61, Power On=62, Power Off=63)

Since CC is OBC=157, I would try OBC's 158 and 159 first.

One final note, to further complicate things, newer Panasonic Plasma and HDTV's also use a few commands from 128.4 and 128.9 (256 more commands for each sub-device to try) so you may have your work cut out for you

Generally, if you have 4 inputs or less, you'll find the inputs within 128.0 (panny 0250). If more than 4, those additional inputs will usually be found in 128.4 I think only aspect codes will be found within 128.9. If you can't find the discrete inputs for 5+ inputs, try 128.4, efc's 3,4, and 8. (Component inputs are most likey in 128.4 than s-video inputs). If you have a newer remote, you *might* find 128.4 as TV_0637. You may get lucky with a newer remote and find a combo, TV_0650 which combines 0250 and 0637 (128.0 and 128.4). Newer being since the 2116/8910 group came out (also 8810, 6012, etc.). That reduces the possibility to the 6131 release batch.

Mark,

You can actually use key moves = assigning advanced codes to try the CC command without a JP1 cable. In key moves you need to use the EFC (not OBC) in this case 000. if you go to the RS15-1994 manual at www.hifi-remote.com it has the proceedure to do "assigning advanced codes"

To really do a lot of key moves the JP1 cable makes that process much easier. You could also create a device upgrade with KM Master or RM with the information provided. The only reason you would need to learn a command would be that one of these doesn't work and your OEM remote has a command that DOES work and you want to figure out the correct command.

Once you get your cable you can use IR.exe to tell you what the Protocol:Device.sub-device:OBC/EFC is for a learned command. If your OEM remote has a closed caption toggle, then you may want to compare that to my list since I made this list from other files posted for Panasonic displays.

I think with our current tools, one never needs to rely on learned commands other than to learn their signature. Learned commands are very inefficient in terms of memory consumed and OFA remotes have very limited learning capacity and we generally recover that memory and use it for device and protocol upgrades.

Ok I now have my jp1 wire. I have plugged it into my 8810w. It worked fine with the Remote Control Programmer.

I have downloaded all the tools, programs and everything I could from the Yahoo files section. I think this has created sensory overload.

It would be great if you could walk me through the steps to find the codes and process for finding how I can eventually just press "on & off" to turn the closed caption on or off on my MX-500. I have a Panasonic PT-40LC12. I believe it is a code 0250 TV. I have tried 000 and that just turns "mute" on and off.

I am really trying to get this jp1 concept and knowledge. It seems fascinating.

Thanks
Mark

I just uploaded a file in the JP1 diagnosis area TV_0250_all_commands.zip that is an IR file for a URC-8810/8811 that has all 255 commands for TV_0250 so you can search. OBC=255 has been omitted since it is a factory reset. There is a spreadsheet that tells you what OBC's are located on which keys for each device button.

So all you need to do is save your existing file in IR and unzip the file and open TV_250_all commands.txt in IR and then upload to remote.

There are no guarantees that any discrete commands for CC exist and still use it at your own risk since we don't exactly know what these commands do in your exact model.

Kinda out-of-date, but possibly useful to you, see:

http://www.hifi-remote.com/jp1/upgrade.shtml

Option 3 under "Finding your EFCs and Protocols" is what you want to do first off...
