JP1 Remotes

Leave it to me to find this kind of stuff -- I guess no one else uses these remotes here on the forum for much -- but there is an error in the RDF for the 1.1 version of this remote. I'm about to delve into the 1.3 version, but I don't think they are they same so the error is not likely duplicated there.

Essentially, the Fav and Last buttons are oddly interchanged with the Ch- and Ch+ buttons. I have made the corrections in the RDF and uploaded it here:

I don't know what section this would most properly be in, Forum- or file-wise, so I just guessed.

Thanks,

Thanks.
Would you mind checking if

By check I mean 1) Manually assign a macro or keymove to the Ch+ key-- use the 995 or 994 commands-- don't do this with RMIR. 2) Make a Raw Download from the remote and post it.

Why do this? Because it is quite easy to make an upgrade which works even though the +/- actions are reversed. But adding subsequent upgrades may not work right. The reason I suspect your RDF has the Ch+ and Ch- button numbers reversed is that the order in the button maps is always Ch+ followed by Ch-. That's true , I think, for every other remote made by UEI. I've been able to confirm that the order shown in the button maps are correct. Of course, there's always the first time, but I'd like to check.

Yes, I think that shows that Ch+ is $1A.
So why does your remote work? One way this can happen--but presumably not in this case--is with a learning remote. The user learns the Ch+ IR signal to the Ch+ physical button, and upon reading the remote with RMIR, it shows that learned IR signal (let's say it is OBC 23) as being learned to the Ch- button--because the RDF has the wrong button number. Now the user incorrectly believes that the Ch- OBC is 23, but the remote works just fine. It still work after the user converts the learned signal to an upgrade.

Another way is the user (for example, me a couple of years ago) gets an upgrade from here, finds that the Ch+/Ch- commands are reversed, edits the upgrade to get a working remote, and then forgets that an edit was done.

I'm pretty sure there are still other scenarios that provide a working remote.

The RDF file informs RMIR which button number corresponds to a physical button, and we want to make sure that the RDF lists the correspondence correctly. The macro method you used is a good way, and quick. Another way is to check with a learning remote or Widget that the OBC assigned to a button in an upgrade is actually sent when the button is pressed. (We need to make sure that nothing else has been assigned to the button with a higher priority, like a keymove or learned signal for remotes with such capability.) By comparison, if an upgrade satisfactorily controls a component, that's only a weak indicator unless the IR commands are known with complete surety.

You've already done the macro method. If you still worried about whether $1A is the button number of the Vol+ button, use one of your learning remotes to check if the expected OBC is being transmitted.

Would you be willing to post the RMIR file for your 7820 that is working?
