PLEASE HELP!!!

I have been reading the forum and trying all of the different tools and cannot get my bin files to work. I really would like to learn how but at this point I would like to get it working. So I have two ccf files with known working codes and need someone to create bins for the slingbox.

You didn't post links to the CCF files, so I'm not sure what you expect us to do.

PM me your email address and I can email all associated files.

Thanks,

Here's a better idea. Zip the files together, then load the zip to the Diagnosis Area (in the File Section) here, then post a link to the file that you just loaded.

Where did you get those? Do you have a Pronto? Did you download the CCF files from some public site?

That diagnosis area is here (you should see an upload button)

https://www.hifi-remote.com/forums/dload ... &cat_id=35

But if you originally downloaded those CCF files from some public website, please post the URLs you got the files from, rather than duplicating them to our diagnosis area.

Ok I posted the *.ccf files in the diagnostics area

https://www.hifi-remote.com/forums/dload ... le_id=6479

However I am not entirely sure these will work. I am still trying to locate a loaner pronto to test the codes with. I do have a learner that will produce pronto format codes so I learned the functions and put them into the pronto file. I can not seem to save or export to .ccf only pcf with ProntoNG. I will work on that over the weekend.

Thanks,

What were you hoping to do with the data from these files? These aren't normal device files, they just have lots of RC5 command codes in them. If you already know what RC5 codes you need, we can easily create new upgrades for you using that data.

And what's the story with the "all in one" file? The buttons are all labeled "RC5 0 0" but the signal isn't recognized by our software, so I would need to decode it by hand. However, I'm reluctant to spend the time that that would take without knowing whether the results would serve any purpose.

You use ProntoEdit, not ProntoEditNG to make a CCF file. But there is no point.

If you have learned codes in Pronto Hex, it is a waste of effort to convert that to a CCF just to reconvert to the form we need.

The program IrTool.exe used with DecodeIr.dll can convert directly from a Pronto Hex string to the form we need.

1) Post at least a few samples of the learned Pronto Hex strings

2) Get IrTool and DecodeIr and try to decode the Pronto Hex strings with those programs. If it works, post a summary of the results, so we can tell you how to proceed. If that doesn't work, post all the Pronto Hex strings.

I'm thinking that we may need to step back and examine what the real goal here is. fz, you haven't mentioned a specific device yet and the CCF files that you posted just contain endless streams of unlabeled RC5 codes.

So, if there are specific device that you're looking to control, let's have the brand names and models, because maybe we already have files for them.

If you read something somewhere about RC5, please post a link to the site where you read it.

If there's any other info that might be relevant, please share it.

The reason I'm asking is because we often see people asking for help with a low-level task, like decoding a ccf file, but what they really should be asking is the higher level question (ie, what they're really trying to do), because they might be going about it in completely the wrong way.

Sorry about not giving more details earlier!

What I want to do is create a driver for the slingbox that will control a crestron system. This will allow the slingbox to stay on one input with one remote and control/view multiple devices.

The files I posted should work when used with the Crestron C2N-IRGW(2series IR receiver), however I only have a CNIRGW(series1 IRreciever), which has a very limited set of codes.
The CNIRGW codes should work on a C2N-IRGW as well.

Initially I didn't know the limitation of the CNIRGW and created bin's that did not work. Thats when the call for help went out. It became apparent the codes I was using were not correct so I found a remote that sends the proper codes. I think I have managed to learn the codes I need but they are a mess. Some codes pulse the command 4-5 times and were very difficult to capture to begin with. See the first ccf command below:

Crestron IRRemote Button command #1
0000 0049 0029 0000 3A00 000E 000D 000E 000E 000E 000E 000F 000D 000E 3A00 000E 3A00 000E 3A00 000E 3A00 000E 3A00 000E 000D 000E 3A00 000E 3A00 000E 3A00 000E 3A00 000E 3A00 000E 3A00 000E 3A00 000E 3A00 000E 3A00 000E 3A00 000E 3A00 000E 3A00 000E 3A00 000E 3A00 000E 000D 000F 000E 000F 000E 000E 000E 000E 3A00 000E 3A00 000E 3A00 000E 3A00 000E 3A00 000E 000D 000E 3A00 000E 3A00 000E 3A00 000E 3A00 000E 3A00 000E 0006 000E

The code was learned with an http://www.engo.com/controlsystems.aspx IR learner that spits out ccf hex and it comes up in crestron as 57142hz, Repeat 0, CRC 0188h. According to the the Crestron learner, which learned this code just fine but does not give ccf, the details are 63492hz, Repeat lenght 24, CRC 14D2h.

I had checked out the IRtool early on but could not make sense of the information it was suppyling. If you could explain its use it may help me a bit.

Thanks,
Fz

I don't know whether to trust that Pronto snippet or not because I've never seen a signal like that before. The difference in size between the "1" on time and the "0" on time is enormous.

Here's what that signal looks like:

freq: 56 kHz
logical 1: "3A00 000E" = 265,143 uS on, 250 uS off
logical 0: "000E 000E" = 250 uS on, 250 uS off

It looks like you were able to capture about 1.6 repeats of a 24 bit signal. Here's the binary...

100001111101111111111111
1000011111011111

IRTool won't work for you here because this is not a known protocol. Actually, IRTool decodes it as GXB, but I don't believe it.

Any chance that you'll find an actual CCF file for your device? Doesn't Creston have anything on it's web site or via customer support email? Their stuff is really expensive, so I would expect them to offer ready made CCF files.

I'm pretty sure that Pronto Hex string is not correct. I think there is a bug in the software that converted the signal from whatever form it was really learn in to Pronto Hex.

What if every 3A00 were 003A instead? (I don't have IrTool handy to check that for myself).

Post by **The Robman** » Sat Apr 04, 2009 4:24 pm

If you switch the 3A00s with 003As, IRTool still says it's GXB

1.6 repeats sounds about right on the first command. I spent the most time learning it. I managed to get it to the point where it would pulse once or sometimes twice. The rest of the commands are 6-10 repeats.

During the learning process it looked like the remote sent an on, an off, and maybe even a repeat command for each button. Do you think its possible to figure out the commands and piece them together? Here are the next two buttons:

0000 0044 0029 0000 3DDE 000F 000E 000F 000F 0010 000F 000F 000E 0010 3DDE 000F 3DDE 000F 3DDE 000F 3DDE 000F 3DDE 000F 000E 000F 3DDE 000F 3DDE 000F 3DDE 000F 3DDE 000F 3DDE 000F 3DDE 000F 3DDE 000F 3DDE 000F 3DDE 000F 3DDE 000F 3DDE 000F 3DDE 000F 000E 0010 3DDE 000F 000E 000F 000F 000F 000F 000F 000F 0010 3DDE 000F 3DDE 000F 3DDE 000F 3DDE 000F 3DDE 000F 000D 0010 3DDE 000F 3DDE 000F 3DDE 000F 3DDE 000F 3DDE 000F 0006 000F

0000 0043 0035 0000 0000 000F 000E 0010 000F 0010 000F 0010 000F 0010 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 000E 0010 0000 000F 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 000E 0010 0000 000F 3EEA 000F 000E 0010 000F 0010 000F 0010 000F 0010 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 000E 0010 0000 000F 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 3EEA 000F 000E 0010 3EEA 000F 3EEA 000F 000E 0010 000F 0010 000F 0010 000F 000F

As for Crestron I have been dealing with them for 10yrs or so and yes they have a ccf for the current IR receiver, but as for most manufactures now, they do not support legacy(limited) products like the one I have. As you said Crestron is very expensive and I have a perfectly good receiver I really don't want to buy a new one!

Thanks for the time,
Fz

I'm going to need many more samples of this signal before I can really have any confidence that I know what's going on. For example, the long ON time in each sample posted above is different (ie, 3A00 vs 3DDE vs 3EEA), so is this difference caused by the learning remote or does it vary based on the button that's pressed?

So, for starters, I'd like to see several (3 or 4) different samples of the same button. That would show me what differences are based on the capture vs. the signal being sent. Then I'd need 3 or 4 samples of the next 3 or 4 buttons, to try and find a pattern. If a particular learned signal appears to send more than one repeat when you test it, please post that info.

In the meantime, I looked over at Remote Central and they have a CCF file that claims to be for the Crestron CNIRGW (here's the file), did you see this file and if so, have you tried it? The Pronto hex looks like the stuff in the "all in one" file that you posted.

Here's a sample from that file for button 1:

0000 0041 0000 0018 0008 0008 0010 0010 0010 0010 0010 0010 0010 0010 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008 0010 0010 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008 0008

If that's the right signal for you, it would be easy to replicate it with a JP1 upgrade that you could use in the Slingbox.
