JP1 Remotes

1. Device: Mac Mini
2. Type of device: Computer IR remote
3. Year: 2006
4. JP1/UEI Remote model: URC9910
5. Do you have a JP1 cable? No
6. Still have original remote?Yes
7. Checked the file section?Yes
8. Checked Pronto file section (at R/C)?Yes, there is a listing for Mac Mini
9. Partially working setup code? No
10. Learning remote question? Mo JP1 cable

Let me elaborate. I am talking about the 6 button midget remote that comes with all recent Apple computers. This remote can actually generate any of 256 6 button sets. I am using MythTV on a Mac Mini and want more than 6 buttons. The IR interface on the Mac Mini is physcially able to recognize and distingusih all 6x256 codes, and no others.

What I want to do is get my URC9910 to generate about 30 of these codes. While the 9910 can capture them, it does not have enough capture memory to hold 30. Right now I'm using a separate learning remote that has more capture memory. What I would really like is a download for the 9910 with at least 30 of these codes.

I don't have a JP1 cable. I have been getting wav file downloads from One for ALL, for my other devices.

I'm hoping that someone knows of a code set I can get from One for ALL, that at least has one set of the 6 codes for Apple remote. Of course it would be even better if someone had a set with more than 6.

The best we can do for you here, unless anyone else here has one of these Mac remotes, is to recommend that you purchase a $15 JP1 cable. Then you can learn the signals using the URC-9910, download the memory, and convert the learned data into an upgrade that you can then re-load into the URC-9910.

I've been in a few different threads about this Apply IR protocol recently in a few different forums.

I think Rob already made a custom protocol for it. But I haven't done the forum search here to find that thread.

To remind any other experts which protocol I mean:

It is similar to NEC1 device 238.135, but instead of a check byte for the OBC, the fourth byte is an arbitrary value giving which of the 256 sets it is.

In other threads we were talking about more than six OBC numbers. In that CCF file mentioned above are the six OBC numbers (third byte) 2, 4, 7, 8, 11 and 13, all in set (fourth byte) 17.

I expect km wants those six OBC values for multiple values of the last byte. That would be very easy with a protocol using two byte hex commands.

I don't know of any official UEI upgrade for that, so I think you'd need to make your own .wav file with JP1 software. The cable would make things easier, but isn't really needed.

.wav files are cumulative in the remote, so if you want to keep any setup codes you downloaded from OFA, you'd need to include those in the .wav file you build.

If the upgrade area gets filled by all that you might want to instead pick a single OBC number (from those six) and then use single byte hex commands to produce any number of the 256 "sets". Your description makes it sound like MythTV would be just as happy with one command in 30 different sets as it would be with six commands times five different sets.

I didn't see a link for any CCF file, so I didn't know we had one.

Johnsfine, thanks for all the info!

First, I can confirm your analysis of the pattern. While I haven't as yet learned the JP1 infrastructure, I have been using the lirc tools. I used irrecord to capture several sets of apple codes, and built a conf file for lircd to recognize them.

The sequences are all of the form 0x87EEXXYY, where XX picks out the set and YY is
one of 02,04,07,08,0b,0d (as you noted).

I'm currently varying both XX and YY, but as you note I could just as easily fix YY and just vary XX.

When I said that the receiver recognized only these patterns, what I should have said is that that with irrecord this IR receiver did not recognize any input from any remote I had other than the Apple remote. My first hope was just to make lircd recognize one of the standard non-apple remotes.

It seems perfectly reasonable to me now that both XX and YY can vary arbitrarily, and that its just that I didn't have a way to generate other YY's. So if the easiest way to generate this is to fix XX and vary YY, I expect that will be fine.

Since its doubtful that any official OFA download will map enough buttons, I guess I need to go down the JP!1 tools path. However, I am a newbie at this, so a little coaching would be appreciated.

The AIO codes I'm currently using are

TV 1610
VCR 0745
DVD 0490
VCR 0636
VCR 0740
VCR 1239
CBL 0476
TV 0156

It sounds like the most straight forward approach is to generate an Apple with XX fixed and enough YY's to cover the 9910 keys, and build one wav file with this and the codes above.

How do I proceed?

Before I saw your last post I assumed your IR receiver was very restricted. You said you tried other remotes and it couldn't process them. But maybe it can receive a wide range of signals and you just tested signals outside that range.

I tired the TV 0156 (Toshiba/Nec) through irrecord and its no good. The program sees the keypresses, but maps all the keys the same way.

This is what it reports

begin remote

name /tmp/nec
bits 0
eps 30
aeps 100

one 0 0
zero 0 0
pre_data_bits 32
pre_data 0x0
gap 211991
toggle_bit_mask 0x0

begin codes
one 0x0
two 0x0
three 0x0
end codes

Compare that to what it sees for the apple remote

begin remote

name /tmp/apple
bits 8
eps 30
aeps 100

one 0 0
zero 0 0
pre_data_bits 24
pre_data 0x87EE4E
gap 211992
toggle_bit_mask 0x87EE4E0B

begin codes
one 0x0B
two 0x07
three 0x0D
end codes

end remote

Is there a different NEC device I should try?

As far as my existing codes, the 4 different VCR's are all Tivo's. Three are identical series 1 Philips, and 1 is a Sony Tivo. Apparently the Sony is built in. The Philips are configured to use different "remote numbers", so I have 3 different downloads for them.

The TV 1610 is an Olevia 532V, with a remote known as RC-LTU. The 5 series comes in different screen sizes and speaker configurations but the remotes are the same.

I'm pretty sure none of the built ins will handle the Olevia, since I went though the procedure of cycling through all the TV codes attempting to find the power button with no luck.

But it appears that Evan S has an upgrade file for the Olevia

As to the Tivos, I had a look at some of the upgrade files but couldn't tell how they distinguished the different remote id's. Right now I'm not very picky on the fine points of the button mapping.

Looks like all the required info is available, we just need to give you a little help putting it all together.

Earlier, I missed most of the Olevia data because it is listed as "Syntax Olevia" and I was looking in various alphabetical lists under O instead of S.

Have you downloaded and tried either RemoteMaster or KeyMapMaster? Or did you look at those upgrades as raw text?

I prefer RemoteMaster. If you had a good reason to use Excel rather than Java, KeyMapMaster might make sense, but you'll need Java anyway for making a .wav file.

Ok, I have RM up and running and have had a look at the Olevia and Tivo rdmu's.

Some questions:

1) I haven't looked at ir.exe. Do I need that to generate the wav files from device/protocol output code from RM, or is ir.exe just for use with a cable?

2) I'm a bit confused on the Tivo. In setup it says "TiVo support up to 9 different unit codes_ change the unit code in the cell above (B7) to change the unit code". I would guess that B7 is a reference to the KM spreadsheet. How do I change it in RM.

3) Where should I start with the Apple code? Should I be creating an rdmu from scratch or modifying some existing rdmu?

The Tivo file I was using is

However, the setup screen doesn't show a "unit code" field.
