URC 7781 and Sky (UK)

[Paul419]

I have just bought a URC 7781 to replace my URC 7555. I was able to re-use the old rmdu file for my Sony TV in the new remote. I have tried downloading all the Sky rmdu files from the file section but can't get any of them to work. I seem to recall I was unable to get them to work with my URC7555 either. My Sky box is a just a plain Sky box - NOT a Sky+ box. Are there any Sky rmdu files which should work with my new remote?
The 7781 has an onboard 0847 code for Sky which works okay. Is there any way to output the code for this and convert it to a rmdu file?

Since the 0847 code works OK (I'm using the 1175 code with my URC 7781, but I have Sky HD), why do you want to turn it into an rmdu file? Is there something missing that you need?

1. Device: Sky
2. Type of device: Sat STB
3. Year: ????
4. JP1/UEI Remote model: URC-7781, URC-7555
5. Do you have a JP1 cable? yes
6. Still have original remote? ???
7. Checked the file section? yes
8. Checked Pronto file section (at R/C)? ???
9. Partially working setup code? SAT/0847
10. Learning remote question? ???

I have moved your post to the Code Search forum and have filled in the template as best I can.

Just for the record, SAT/0847 uses the $0020 protocol (RC6-M-20n) with fixed data "A9 30 55 55 55". I don't know what values to enter into RM to get that fixed data though.

Thanks for the reply Graham. I want to set up my 7781 as near to the 7555 as possible - I've got used to the default setup provided by OFA for the 7555. I should be able to do it by using the learning function but would like to avoid that if possible.

8. Checked Pronto file section (at R/C)? No - haven't come across this file section
10. Learning remote question? No, although the 7781 is a learning remote.

Thanks Rob. Some of the rmdu files I tried used the RC6-M-20n protocol but the signals were not recognised by my STB when transmitted by the URC.
If not too much trouble could you please explain the significance of the 5 bytes of fixed data?

I know that question was addressed to Rob, but I'll try answering it. Most protocols are very versatile and need additional parameters to specify exactly how they will work. These include such things as device and subdevice codes that are sent as part of the IR signal. As they are the same for all keys, depending only on the piece of equipment being controlled, they are "fixed data", as distinct from the "variable data" that codes which key is being pressed.

I want to set up my 7781 as near to the 7555 as possible - I've got used to the default setup provided by OFA for the 7555.

If you mean that code 0847 has all the functions you want, but not on the keys you want them on, you don't need to use learning to put them on your desired keys. You can just use Key Moves, which takes far less space in the remote's memory. There can't be many functions that are on the "wrong" keys, surely.

If Key Moves isn't sufficient for you, can you be more explicit about the changes you would like to make to code 0847 and I'll see what else I can suggest (or do).

Thanks for the fixed data information Graham.

Code 0847 does have all the functions I want. I have all the 7555 5-digit codes for Sky for use with 'Key Magic' and they probably will work with the 7781. I have never used the Key Moves section of IR.exe so I will try and figure out how it works as it looks rather useful! I have just downloaded a couple of Pronto ccf files along with Pronto IR Tool and Decodeccf so hopefully will make some progress.

[mathdon]

I know nothing about the Pronto stuff. You certainly don't need that if your problem is simply that functions are not on your preferred keys. You don't even need to know the 5-digit Key Magic codes (called EFCs in JP1 terminology).

To create a Key Move (the Add button on the Key Moves page) you first put in the device/key combination that you want to use to perform some function (this is the "bound key" of the Add form). Then, in "Function to perform", double-click the device that currently has that function. In your case, both the bound device and the function device will be the device assigned to SAT. Then, in the radio buttons on the bottom right of the "Function to perform" box, select the button marked "Key". In the drop-down box you will now find a list of all the remote's keys. Select the one that currently performs the function you want. Finally, press OK and a new line will appear in the Key Moves grid giving the move you have created.

Note that the device/key combination under "function to perform" is the one that performs the function in the unmodified setup code. By this I mean that you can do, say

From Dev2/Menu To Dev2/Guide
From Dev2/Guide To Dev2/Menu

without causing an infinite loop. If Dev2 is set to SAT, this would swap the functions of the Menu and Guide keys for the Sky box.

Please feel free to ask further if you need more help.

PS In writing this, it has dawned on me that the headings "To" and "From" on the Key Move page, put in by me in response to the suggestion that having two columns both headed DevButton was confusing, are the wrong way round. It should really be "To" in Col 1, as this is new key to perform the function, and "From" in Col 4, as this is the old key that performed the function. I'll have to correct this!

Thanks very much for your help Graham. Using your simple instructions on how to use the Key Moves page I now have my 7781 set up exactly as I want!
