URC-7980 & Panasonic Plasma

zdzislaw22 · Post by **zdzislaw22** » Wed Feb 27, 2019 12:39 pm

Hello all,

I recently bought URC-7980 remote and trying to configure it to work with Panasonic Plasma TV which requires long press of power button. Because of this I cannot properly build the macro to turn TV on.

I read several threads and found some configurations with macro friendly custom executors, but unfortunately they were built for different processor.

I'm wondering if it would be possible to built such custom executor for urc-7980 remote?

It looks like the URC-7980 uses the TI2541 processor, so I don't know if that's possible.

Is there any chance to achive expected result (long power press) different way?
I'm thinking about modification of learned signal.

Below it's what I get pressing power button for long time on the original remote. I think URC learned shortest possible sentence, because it still acts as short press.

Ok, this will get somewhat hairy, but at your request, here but we go.

The Pronto Hex form in general consists of an starting sequence (here empty), and a repeat sequence, that can be sent as many times the user desires. So that is why the given signal only sends "as short".

It is possible to convert the given signal to a "long" signal in that you have an intro sequence consisting of a number of copiers, and then (probably) no repeat sequence.

You can do this manually. For this set the forth number to "0000" and the third number to the length of the new intro sequence, as a four-digit hexadecimal number. (See my explanation of the Pronto format if necessary.)

You can also use the command line program IrpTransmogrifier to generate. For this, you have to know that the signal uses the panasonic protocol, with parameters D=128,F=61,S=0. The command for generating 3 signal goes like this.

Code: Select all

$ irptransmogrifier render --count 3 --pronto -n  "{D=128,F=61,S=0}"  panasonic

Thanks a million for the tip.

When I put above data into Learned signal definition field and press Apply, I get error message saying "Malformed learned signal: duration list extends beyonds hex data"

I also tried to build it from scratch and found that when I set 2 repeats, all works, 3 repeats results in above error.

So, it looks like there is a limitation either in the remote or RMIR.

Will the discrete ON do what you want instead of using the long press?

I just checked into this and there is indeed a limitation in the remote software itself. There is a byte where you specify how many bits are in the data string where the MSB is a flag that states where it should repeat or not, which effectively limits you to 127 bits of data. The Panasonic signal uses 50 bits of data, so you can get away with 2 repeats (ie, 100 bits) but not 3 repeats (ie, 150 bits). The Pronto format doesn't have any such limitation.

You could try the following, which sends 2 repeats once, then 2 more repeats while the button is held. I don't remember if you'll get at least one of the held repeats in a macro.

Thanks Rob for help,

It almost works. Outcome of my tests:
- pressing a button (with a code Rob provided in previous post assigned) once doesn't turn TV on
- pressing it quickly twice wakes TV up. It doesn't work in a macro due to delay between commands. Is there any way to manipulate/remove this delay from the macro?
- pressing standard wpoer button quickly twice (or more times) doesn't turn TV on

I see, new command works better than standard one. I think having signals trippled should work, but it's a remote limitation.

p.s. I tried to download Texas Instruments TI 254x processor datasheet but the link doesn't work to me.

EDIT: I've found THIS topic which is similar to mine. The solution 3FG presented in second post from bottom looks quite simple, but it's for MAXQ610.

EDI2: I did the same for TI in RMPB and POWER works perfectly in macro.

Congrats, I take it you know how to write TI code? Please post details

I fixed the file link for the TI data sheet, but here's another link for it too:

Haha,
I wish, but truth is more trivial. It was only lucky guess.

I realized that protocols definition for MAXQ610 and TI2541 are very similar. So, I did exactly the same what 3FG have written in thread mentioned above and I changed "42 54 06 71" to "43 54 61 08 71" for TI2541 protocol.

After change protocol looks like:

01 11 01 21 51 0E 10 00 10 00 10 00 30 00 9D 0A 80 00 40 00 00 80 08 07 08 05 06 07 08 08 07 43 54 06 08 71 72 73 74 75 76

Because RMPB properly analyzed it

...
PF byte interpretation:
Use normal lead-in on all frames
One-ON precedes lead-out
Use normal lead-out as gap time
Send 8 mandatory repeats
All buttons repeat on held keypress
..

I gave it a try and works.
