I expect the 800 means Panasonic:128.0 and the 804 means Panasonic:128.4 and the "Data Code" translated from hex to decimal would be the OBC number 3D is 61, DE is 222, etc.

With that information you can easily create the signals using MakeHex (which I don't have on this computer, but will post results tomorrow if no one beats me to it).

I do wonder what they mean by listing the same command for POWER ON as for POWER OFF. If that a typo or a strange way of saying there is no discrete?

I also wonder what more Jon wants from the document, since Jon knows everything I just said above (as well as complete details of how Panasonic uses the Kaseikyo Format).

BTW, it looks like the commands that have been published before. Note Power On and Off are the same command.

Many times, often by you.


I did notice the many places that 128.0:61 was listed (as it is here) as both the Power On and Power Off command. But I also found places where 128.0:62 was listed as Power On and 128.0:63 as Power Off.

To avoid making Kevin redo all those searches, I'll just gather the results here:

I would be interested to see if these codes (especially the discrete on and off) will properly operate the newest Panny plasmas. Specifically the TH 42PX25UP. I have installed one in a customer's home and am using some work arounds, but would love to know if these codes will work for future jobs. I believe the PX20 series is the same as the PX25 except that the 25 series includes an ATSC tuner and possibly a Cablecard slot.

Any one who actually tries these codes on a PX series, please post your results!

None of the input codes work for the TH42-PWD6EX.
Barend

Where did you find discrete on for the TH-42PA20? I didn't find that model listed.

I can shed 'some' light on what panasonic sent. You may already know most of this.

1 0000 learned/raw data
2 0070 carrier freq (36.68 khz) (cycle timing = 27.26us)
3 0000 first burst pair sequence length (zero in this case)
4 0032 second burst pair sequence length (50 burst pair)
including the lead-in and lead-out
5,6 0080 0040 8T 4T, the header for this device, 80h = 128d,
128/36682 = .003489 seconds or 3489us or about 8T. The
calculations for 4T are the same yeilding about 1745us.
7-70 determines the group number, each pair of words determines
a '1' or '0'. 0010 0030 pair is '1' and 0010 0010 pair is '0'.
That's the data 0 = <-T-> <-T->, 1 = <-T-> <---3T---> .
Every 4 bits makes a nybble and is read as such. 64 words
equal 32 bits. The 32 bits are read a nybble at a time.
The group number is 4004 0100 for power (on, off, toggle)
71-86 First byte of button code, 1st nybble of 1st byte always
repeated in 1st nybble of 2nd byte (don't know why)
87-102 Second byte of button code
103,104 lead-out, should be about 76,000us

That's about all I can tell you about what they sent.

There is only one byte of button code, the one you called "1st".

The byte after the button code is a check byte that is the XOR of the button code with the one and a half bytes before it.

The nibble of check byte that you say is always the same as the corresponding byte of the button code, happens to be the same in MOST (not all) of the signals in THIS (what Jon posted) list of signals, and then only because those nibbles of the preceeding bytes happen to be zero.

Based on incorrect reverse engineering I did years before I saw an official spec of this protocol, my software calls the byte before the button code "subdevice" and the byte before that "device". Many other programs in the JP1 group and here had adopted that convention before we discovered it was wrong, so it was easier to leave it wrong.

So in that list you see commands with "device" 128 and "subdevice" 0. Those two bytes have zeroes in their low half resulting in the duplication you described. But the ones with "subdevice" 4 don't have that duplication.

Actually the low half of the byte I misnamed "device" is really a check nibble for the manufacturer code and for Panasonic, that nibble is always zero. I forget the official meaning of the three nibbles that make up the other half of "device" and both halves of "subdevice", but those meanings have been published in a few threads at RC. When using generic tools based on reverse engineering of multiple disimilar IR protocols, it is simpler to ignore protocol specific meanings like that and cram almost everything other than function codes and check bytes into the device.subdevice paradigm.

You're right. After digging through the last couple of pages of an old panasonic (not that old) IR spec sheets, I see that several codes for their amps and some CD players have different values for the 1st nybble of the 1st and 2nd byte.

The potion you were calling device was always 4004 (in these references) and sub device varied (0100 - tv, 0900 - video, 0980 - vcr, 0543 - amp, tuner, CD, and tape). Carrier freq was given as 32khz, but I see now that 36khz is being used also. (I tried 32khz and it seems to work fine if the other codes are adjusted to correct the timing.) The timing for lead-out, pulse and space are all maintained using the higher freq. However the timing seqence for the lead-in was changed slightly from <10T> <4T> to <8T> <4T>; (T being about 400us).

I am fairly new to all this, and have been trying to get the codes correct for a panasonic rear projection lcd. The TOAD codes will turn the set off, but will not turn the device on unless it is within it's cool down period. I found that by repeatedly sending an 'on' code and slowly accelerating how fast the codes are sent, the set will switch on once the codes are sent close enough together. So I set the pronto to send two 'on' codes seperated by about 100ms. This worked fine for 'on'. A bit of a problem for 'off' as it would cycle the set to off, then on again (very quickly). Not a big problem, but irritating.

Is there a problem with the lead-in of some off these code that is keeping the device from having the time to properly set the receiver? Is there a null code that can be sent?

All,

I have the Panasonic TH-42PX20. I also have the URC-6131 (mod by Rob) and I am attempting to load the discreate code I uncovered (via this forum..thanks) using IR (v.6.00). I converted the Pronto HEX in ERC codes e.g. comp1 =004, comp 2 = 008....but none them seem to work....can anyone shed some light? Thanks.

You need to pay attention to the subdevice in these signals.

For example:
Device Code: 128.4 Function: 124 - Comp 1

There the device is 128 and the subdevice is 4 and the OBC is 124.

You correctly converted the OBC of 124 to an EFC of 004. But I suspect you used that with a setup code for device 128, subdevice 0, rather than subdevice 4.

If you need detailed help, ask in the JP1 forum rather than here. Basically, you can either make a dummy setup code for Panasonic:128.4 and base EFC KeyMoves on that, or you can build a new setup code for the whole device using a combo protocol that allows 128.0 and 128.4 in the same setup code.

Thanks....I will try there...I was a little confused about what you said (cause I'm a newbie). In IR I just setup keymoved and it just asked me for EFC so I entered 004....do I need to do more.

Yes you need to do more. But lets continue this in the other forum:

I've had trouble finding the discrete on command for a Panasonic TH-50PX25U/P Plasma. I've taken the codes on this thread and tried them, but the on command won't work. The off command works fine? Has anyone else run across this problem? Thanks for any help! Stoney

Hi...

Did you ever get a response to your discrete ON issue?
