JP1 Remotes

Okay. It's been over 8 years now with this equipment. My prior thread is here.

I just got a couple LCD TVs and they seem to interfere with the IR. So I bought a LCD resistant IR receiver for the new set to back feed the equipment closet. The pulse (no carrier frequency) codes for the subject equipment that we generated previously don't seem to pass through the new IR receiver unless you are within a couple feet of the receiver. They do, however, have codes available with a 40.2kHz carrier that do work from across the room with my 10820 learned.

The Hex functions are the same for both the pulse and carrier versions, but the protocol is where I am having problems. When I used the programming box for the Elan panels (Via Tools), I can learn the carrier codes into the 10820 and IR reports Vellemen as the protocol. The learns work the equipment, but I can't seem to get Protocol Builder to generate the right code as Velleman is not the exact variant (just close in timing).

Here's a sample of the IRP for audio source:

I see there are 6 different device codes.

D:4, F:7
So you are probably going to want to have some sort of combo code.

We can do this as a 1 byte functions, if you only need 4 of the device codes, or 2 byte functions to get all of the device/function combos.

What did you have in mind?

Also is this going to be for the 10820? Or do you plan on using a different remote?

Ok, I've had a little time to play with this a bit.

What I know.....

The signal is 40.2kHz, structure is dev-cmd

5 bits/dev, 6 bits/cmd .....one byte for each and then the lead out

Burst pairs are 500/7200 for "1" and 500/4600 for "0"

Lead out is off is "63000", style is [Oneon, -LO]

I was able to build this protocol in protocol builder.

First:
Okay, first thing that jumps out is that you have the leadout time wrong.
If you look at all the learns in the CCF file that have the ones and zeros that your looking for you'll see that the more 1's there are the shorter the leadout time is. So this means that the signal has equal frame lengths. That means that the leadout time is 122000, and the OFF as Total = YES.

Second:
Its really hard to tell you why your bumps don't line up when we don't have the RM or KM file, because that's where the OBC values get interpreted. So please post the file.

Third:
Which of these signals do you need? Because it looks like you may need some kind of combo code if you need to need all of them.

Oops, when looking at this again, I noticed the model number in the title and recognized the model number Z880 in the CCF data. So you probably just need the the last group of codes.

This makes me ask WHY did you decide on a 5/6 split on the device to function? Tthe last 7 bits change over the range of signals, clearly calling for a 4/7 split. As I said above:

Hmm, I might have been a little tired and I didn't consider the possiblity that you were planning on a 4 way combo.

The reason I was advocating a 4/7 split, and not a 3/8 split, was for the possiblilty of a 2 dev combo. With a 3/5 split you could create a 4 way combo.

If I look at the entire set I do see 4 distict values on the first 5 digits

00000
00001
00010
00011
00101

In a situation like that you would need two bits in the hex to select one of those values for your combo and of course you'd still need a helper if you needed all 5 values, but then you'd need a couple fo upgrades anyway to get the whole list in a remote.

I chose the 4/7 split because the instead of the Elan HD group had two valuse in the first 3 bits or the first 4 bits, so a two device combo would be a good choice, 7 for the OBC and 1 to choose the device.
000 00000000
001 00000000

If you need all 5 devices, maybe a 2 byte function code should be used.

I'm following you Vicki.

I chose the 5/6 because the Z880 and S6 don't have commands OBC above 63 for the most part. The Z880 uses a few above that for Outputs 17-24, but I won't use them. They could be addressed nonetheless. I'm sure a 4/7 would easily cover this. The Elan HD and SR1 could be address with the mini combiner I'd assume, but that's out of the scope of what I'm trying to accomplish as I don't have those devices.

So here's my working files from PB, IR and RM. It's producing the right format, but not all of the buttons are working and they are mapped incorrectly. I.E. I can press 1-3 and they produce a signal with the wrong OBC, The buttons 4- doesn't work even though I have them mapped in RM.

And yes, you were correct, the off as total is part of the issue.

Still not sure why the buttons are screwed up.

Oh. Another thing I am using the pulse version of my RM file for the template as the OBCs are the same. If you look at it, it uses the 5/6. I just noticed it has the Off as total set as well.

And one last thing. Thanks for your patience! I really appreciate your time as I am trying to understand this. I'd like to be more proficient, but I tend to forget what I learn when I take these 1-5 year breaks from it.

Thanks Vicki. That was it. Those two settings were hiding from me the whole time!

Now it seems to work fine. The buttons 4- didn't work when I uploaded from IR, but the same upload from RMIR worked fine. I'm not sure what's going on there.

Now since I got this going. I may screw around with the other Elan HD and SR1 just for fun and a learning experiment.

Alright. This upgrade is tested and works awesome with the new LCD/Plasma proof IR receivers I just got. Before with the old IR receivers, I'd have to wait about 3-4 minutes for the TV's backlight to warm and stop emitting all the IR noise washing the old receiver. With the new IR receiver and this upgrade, I can adjust the volume on the S6 and change the video sources on the Z880 immediately.

Here's the upgrade with all the functions.

thanks again Vicki!

P.S. Just because I want extra credit, I may start experimenting to get the Elan HD and SR1 for an upgrade.
