Can anyone help me find the codes for a Grundig colour tv, type sp 55-550 text. I hesitate to call to the helpdesk since I live in Holland. My original remote has broken down, so I cannot use infrared learning.
Thanks!

Your recent post under another name (or was that a family member?) said "kameleon 8 in 1", but to help we need to know which one.

We use the model numbers (URC-9960, URC-8060, etc.) to say which model a remote is. The names are not specific enough. (I also don't recall which Kameleons are 8 in 1).

For a European Kameleon, the Grundig TV setup codes are probably built-in and documented in the manual, and if they're not built-in, I think there is a European OFA website you can download the .wav file from for upgrade.

Somewhere I have the information on the few different code sets used by Grundig TV's, but there's probably more complete info on OFA's web site.

If you have a USA Kameleon then you'll need some more help.

There's just 2 "8 in 1" Kameleons and they're both American...

Radio Shack 15-2138
One For All URC-9960

The only Kameleons available in Europe and beyond are...

One For All URC-8060 (6 in 1)
One For All URC-8040 (4 in 1)

I guess I should have looked that up before posting.

I also can't find the data I thought I remembered on some Grundig TV's that DON'T use the typical Grundig codeset of Blaupunkt protocol, device 0. I couldn't find that today. But anyway the typical one would be the place to start.

I believe both the Grundig and Blaupunkt TV upgrades in the JP1 TV folder use that, so that would be a good starting point if you want to make your own .wav file for a 9960 or 2133.

I also checked and found that USA Kameleons have no built-in setup codes for Blaupunkt protocol.

Grundig SP55-550 Text?! I know a Grundig Super Color 55-550 Text and a Grundig ST55-550 Text, if I 'm not mistaken both TVs will work with TV code 0195.

Please doublecheck the modelnumber of your TV and also check your broken Grundig remote control, this remote has it's own modelnumber, normally starting with "Tele Pilot" or "TP" and then a 3 digit-number, it will help us to determine the right setup code. Please also mention the brand & modelnumber of your universal remote.

Thanx for all your replies so far. I'm sorry for entering the wrong code for my tv. My Grundig tv is of the type: ST55-550 text, and its original rc has type TP 663.
My universal rc is a one-for-all,modelnumber URC-3330

I have tried code 0195, but unfortunally it didn't work. I'm am groing very impatient with this piece of device, my husband got it for his birthday from a friend who visited the USA, but when this stupid thing won't work it's not much of a present, is it?

Please respond one more time;)

Thank you,

greetings,

Brigit

I'm affraid I have bad news: the correct code is TV code 0195 but I'm not surprised to hear that this code doesn't work at all. The problem is not the TV or the One For All remote, it is the Grundig TP 663 remote that gives trouble. I will try to explain the problem (please excuse my bad Englisch, I'm German):

IR-eyes and IR-remotes are supposed to work on a fixed frequency & timing. However, if a manufactor produces remotes for TVs who should send a 40 KHz signal, most of these remotes will send a 40 KHz signal but you will also have remotes who send a lower 39 KHz or a higher 41 KHz signal. To avoid that these remotes can't operate the TV you allow the IR-eye of that TV to accept signals within a frequency from 38 to 42 KHz (+/- 5% tolerance). Then a remote who sends 39 KHz instead of 40 KHz is still able to operate the TV.

However some remotes might alter and drop frequency (I'm not sure if it's actually the frequency or the speed (aka timing) that drops) after a few years. Some TVs might stop working on the remote, but because this alterings process goes slowely it also might happen that the IR-receiver gets used to the altered signal and still works, even if the frequency of the altered remote has droped to 37 KHz.

However if you try to use a second remote who does send a correct 40 KHz signal then the TV might not work on the 40 KHz signal because the IR-eye is used to receive a 37 KHz instead of 40 KHZ and 40 KHz is beyond the 5% tolerance limit.

Now this problem is very rare, in my own OFA experience (I helped over 25000 customers to setup their OFAs), I know this problem from an old series of analog Amstrad satellite receivers and from older Grundig TVs with TP 663 and TP 623 remotes.

With the Amstrads you can solve this problem by disconecting the powercable for 10 minutes, then connect and Power On the receiver and use the new (correct) remote and the IR-eye will automaticly adjust to the new & correct IR-signal. However with these Grundig TVs I have never heard of a way to solve this problem.

That's an interesting theory about the deteriorating IR signal. If it's true, there may well be a solution.

Brigit, how much effort are you willing to put into getting this to work? If you were to get yourself a JP1 compatible One For All remote and a JP1 cable, I could modify the TV/0195 code for you so that it sends a signal with a lower frequency. We could keep lowing the frequency until we find a value that works.

If I remember correctly, the URC-3330 needs some parts soldered in for it to be JP1 compatible (take a look in the battery compartment, if you see 6 little holes, then this is the case). Assuming that you don't want to start soldering, you could pick up a remote like the URC-7562 locally which is JP1 ready, right out of the box.

Next you will need a JP1 cable, which you could either make yourself (which means soldering) or you could buy ready made from one of the two JP1 vendors.

Another option is that I could pre-program a US remote with several different versions of the TV/0195 setup code, each with a slightly lower frequency and send this to you. You would still need a JP1 cable if you would want the remote to also work your other gear as US and European remotes are loaded with different codes, so a US remote would likely be missing the codes for alot of your locally purchased gear.

Mr_E, are you familiar with JP1? If not, you definitely should be. Drop me a line if you want to discuss it.

Your other posts are so consistently knowledgeable that I'm almost tempted to believe the above. But it's quite far in contradiction to my understanding of how IR receivers work. I'd suggest looking for a better theory for why 0195 doesn't work and what might be done about it.

With the Amstrads you can solve this problem by
disconecting the powercable for 10 minutes, then
connect and Power On the receiver and use the
new (correct) remote and the IR-eye will automaticly
adjust to the new & correct IR-signal.

That's a little less far fetched. I know that some IR protocols are designed in units of some input frequency but without specifying the frequency exactly, so that different remotes may use different input frequencies. I also know that on other IR characteristics a few devices have been designed to allow more of a choice when first plugged in than they normally allow and to lock into the characteristic of the first signal accepted (but not drift with it over time while still plugged in). I don't know of examples where the characteristic handled that way is frequency, but it wouldn't surprise me.

Anyway, it seems quite a leap from 0195 didn't work to this frequency theory.

As already mentioned in my previous post, I'm not 100% sure if this alterings process has something to do with the frequency or with the timing. But its defenitly an alterings process.

I started to work for OFA to do the german CS in 1997 and because Grundig TVs were popular in Germany, I got many calls about Grundigs with this TP 663 remotes (at least 50, probably a lot more). In the first 3 years, I never had problems with these TVs, TV code 0195 always did work.

However, in the next years I worked for OFA, I was very surprised that at one day I got a call from a customer with a Grundig TV with this TP 663 remote and that TV couldn't be operated with 0195. The TP 663 still worked for this TV so I thought something was wrong with the OFA and after doublecheking with my supervisor I offered that customer to exchange his OFA... ... only to find out that the new OFA still couldn't operate the TV though we know that this OFA-model worked in the past for these Grundig TVs!

So this time my supervisor and I consulted our databaseguru (a very nice girl who in my personal opinion really is a kind of Einstein on codes for universal remotes) and than we here about Grundig TVs with this TP 663 and that in some cases 0195 simply wouldn't work.

In my last year at the CS I saw this problem more and more often because of the then there were some older Grundig TVs and TP 663 remotes we were of an older produnctiondate. To avoid misunderstanding: Grundig is a brand who develloped the IR-protocol behind this code 0195 a long time ago and still is using this protocol for new televisions. This protocol is also in use by other brands (Siemens, Blaupunkt,...) and I have seen at least 500 different TV models who are using this codesystem 0195 (just as Sony develloped the IR-protocol behind TV code 0000 twenty years ago and still uses this protocol for new TV models).

You won't have any problems with Grundig TVs who are supposed to work with 0195, unless you have a Grundig with these TP 623 or TP 663 remotes and the TV is already older (remember, when these TVs & the TP 663 were still new, TV code 0195 did always work!).

@johnsfine:
Perhaps I'm wrong in the technical details of this altering process & the IR-eye , but I'm 100% sure about that these issue occur with the Grundig TP 663 remotes. As long as the Grundig TV is quite new, an OFA with TV code 0195 will work fine.

However, when the Grundig TV and the TP 663 are getting older, there is an increasing change that 0195 might not work! When you say that this is not the way that IR-eyes should respond, I believe you right away, because there are so many thousends and thousends of even older TV models than these Grundigs and there we never saw this problem happen. It's really a problem of these (please excuse me Brigit) stupid Grundig TP 623 & TP 663 remotes.

@Brigit:
Just to doublecheck, is it correct that your Grundig TV is not a newer Grundig model with a remote from the TP 663 series, but is already an older model? Let's say I expect the age of you're Grundig TV closer to 6-10 years old or perhaps even older than to 5 or less years. Is that correct?

@Rob:
you right, this JP1 stuff is very interesting, can you imagine that in all these years I worked for the OFA CS I never have heard about these JP1-kits?! I will also send my former OFA collegues (and still good friends) an email about these JP1-kits, I think I'm not the only one who wants to buy a kit!

Hi guys,

I'm really pleasantly surpised en astonished by the ammount of knowledge spread over me in your e-mails. I would like to say thank you for your afforts to help me so far. It is correct that my tv is an older one, I would guess it's about 8 to 9 years old. But a true golden oldie, because it still works like a charm.
I am quite a tecnical lady, but soldering and JP1 kits, that is something that is out of my league. So that is unfortunally not an option for me.
Neither is it to buy more equipment, or a new remote, because although it can not work all the functions I need for it to do, my old all-for-one remote still operates the main functions on my Grundig dinosaur:)
There is something in the whole line that strikes me as inconsistent: why does my old one-for-all (the URC 3330) works with code 0195, and this new one doesn't? If it was a matter of lowering frequencies, than why doesn't this affect the URC?

For now, I am taking in the bad news of realising that my old tv will not work to state-of-the-art modern equipment. Maybe I'll have to face the fact of saving enough money for bying myself a brand new, shiny, modern tv. But for now I am going to watch the olympics and zapp through my channels with the URC.
So, once more:
Thank you guys!!!!!!!!!!!!!!!

Love, Brigit

I think we've been confused about what problem you are describing.

Let me see if I understand it now.

You have a URC-3330 in which the setup code TV/0195 does work and your husband has a URC-9960 in which the setup code TV/0195 doesn't work.

If that isn't it, please tell us more clearly.

If that is a correct description then the problem is that setup code TV/0195 is not included in the URC-9960. It can be added by an upgrade loaded by .wav file.

Hello johnsfine,

that is the correct description for the problem, our new rc is a URC 9960 (kameleon 8) and it will not work with code 0195 on a Grundig tv.
How can I get this upgrade? Do I need a kit for it?
You spoke earlier of a european website, I looked for it but could not find it. Do you have an URL for me?

I don't have the URL for getting .wav files for European OFA remotes, but it wouldn't help you anyway because the .wav file for a European Kameleon wouldn't work on a 9960.

I don't know why OFA provides .wav files for European models via internet but for USA models will only play the .wav file over the phone for you. Via phone is less convenient and I guess for you is also more expensive. Maybe MR_E will comment on that policy question.

With free JP1 software (start from Rob's web page to find that) you can create your own .wav file to upgrade the 9960. You don't need the JP1 cable nor anything else that isn't a free download.

That process requires a fair amount of knowledge about JP1, but has the advantage that you get to select which functions go on which keys, and maybe include functions OFA forgot in TV/0195. You also could create a larger .wav file that configures the entire remote (for other devices, KeyMoves, Macros etc.) rather than a .wav file for just TV/0195.

If you want just the basic TV/0195 and don't mind having someone else's guesses about which 9960 keys are appropriate for which Grundig TV functions, any of the JP1 experts could easily create the .wav file for you. I have upload rights to some of Rob's web space. If he doesn't think it's an excessive use of the space I have been thinking about posting URC-9960 .wav files for a few of the more popular European devices, since requests for such upgrades are getting to be rather common here. (But you'd like the final results better if you used the tools yourself and assigned functions to keys the way you want them).

Ofcourse I would like to configure my rc to my own needs en appliances, but I know nothing about JP1 so far. What I understand from what you're writing, is that I need to make a .wav file that I then can play of to start my 9960 learning witch function I want with witch keys.
Because my husband is a computer programmer, I think he can get a long way trying to learn this JP1 thing. For me his is getting just a bit to complex for my understanding of technical things. So he just said he will try to learn as much as possible to start with this stuff.
He will start by reading Rob's website, and try to figure it out!
