JP1 Remotes

Thanks yet again guys.

Jason, I too thought about the batteries and replaced them with new ones at the start of this process.

Nils, I too think it has something to do with the RF side of things (I think it is a timing issue of some sort). However, your post intrigues me! I'd like to try it before giving up. Having said that, I do know know what your post means and what I should try . How do I change 00 DF DF to 00 DF 00 or 00 DF 20?

Also, thank you very much for the 15-2117 info. I really do NOT like the 9910! When you say they are going for $30 now, does that mean they are discontinued or on sale?

Thx.
Julie

In order to tinker with the fixed data you will need to create an upgrade for the device. I uploaded one to the jp1 files/diagnostics area called "Julie TV-1030 15-1995.txt" for you to try. You will need to open it with KM and copy/paste it into IR. You will see on the setup panel of KM where the parameters are that you can tinker with. You can also set the codes on the buttons you want on the buttons tab.

Yes, they are discounted at Radio Shack for $30 the same as the 2116. May be marked higher but should show up on the register at $29 and some change. By the way, of all my remotes the 2116 is my favorite

That won't do anything. When the first byte is set to 00 the 3rd byte is totally ignored.

Julie, hang on in there, I will hopefully have something for you to try soon.

In the meantime, could you learn some buttons from your Apex using the URC-9910 and email me the IR.exe file so I can see exactly what the original signals look like.

Rob, my goal was to give her an upgrade that might work in her 1995.

I understand, I'm just saying that that change won't actually change anything.

Rob, Understood.... and yes, I did forget about that but thought installing the upgrade might help anyway.

Julie, is it possible the RF is working when you are in the room with the DVD player and RF relay? Try covering the IR emiter when you are in the room and see if the RF is working when you are close. Just a shot in the dark that maybe the RF in the 1995 is weak.

That's doubtful since she's controlling other devices via RF, isn't she?

That is what I was originally thinking but it also sounds like the DVD is in a different room from the other viewing equipment. I was thinking that the RF is just not getting from the viewing room to the DVD room. Even if all the equipment in the viewing room is on RF it is local to the remote. Basically what I was getting at is does the remote just not reach the DVD room from the viewing room and does the RF reach the viewing room from another room.

It just seems logical to me that if the RF works at a distance to one piece of equipment it should also work to another piece of equipment. Simply put, trying to rule out a distance issue with the 1995.

Quickly to explain my configuration:

I have only a TV in my living room. All of my other equipment (DVD, CD, AMP, VCR, and Sat receiver), is in another room. The remote controls every other piece of equipment from my living room. It is just the DVD which does not work. If I go into the room with the DVD and unplug the "command center" I can control the DVD by aiming the remote just about anywhere in the room. If I plug in the command center and cover the front (IR sender) of the 1995 remote (still in the same room as the DVD) I cannot control the Apex DVD anymore. However, I can control everything else in the room just fine.

I think I understand by reading the other posts that I should not try the upgrade that Nils was kind enough to upload (thanks Nils !) as it looks as though it will not change anything. If this is incorrect, please let me know and I'll try the upgrade.

In the mean time, I am going to take Rob's advice and learn some buttons from my Apex remote into the 9910 and upload the file. I'll do that sometime tonight.

Thanks very much guys! It's really appreciated

Hey Julie,
Let's try something here. I've got a completely UN-TESTED protocol for you to try, the timings in the protocol have been tweaked a bit in an attempt to compensate for whatever signal degredation might be occurring via the RF link.

I have no idea if it works, either from the remote or via the command center, but it can't hurt to try it.

Here's what you do, in IR.exe go to the Protocols tab and click the ADD button. Then in the main box of the pop-up window, paste the following code...

15 10 31 80 15 F6 B8 01 17 08 08 01 A6 03 1C 69
78 56 06 CC 02 08 01 01 03 DB E6 5B 3C 02 5C 97
5D 05 7F 7F 3C AE 73 57 5D 17 22 10 D0 13 A7 5D
04 E6 5B 80 0C A9 80 45 5E 85 5E A9 80 45 5F 85
5F B7 5D 03 3C EE 7E 07 5D 20 77 5D 04 22 09 90
19 37 5D 02 22 00 97 5D 0F 22 00 3C C0 7E 44 5E
3C 01 6B 22 06 90 03 60 4F 7F 2F 7F 4C 00 FF

Then in the little box labelled protocol id, enter 5A.

Then re-load to your remote and give it a whirl. First try it using just the remote, then try it via the RF link.

Rob,

I tried the code that you posted for me and UNFORTUNATELY, it did not fix the problem. However, here are some other observations while trying to contol the DVD using the code:

1. I was able to control the unit just fine via the IR from the remote (just like before, I do not notice any problems and there is an immediate response via IR).

2. Before I loaded the code, I was able to control the DVD via the RF VERY unreliably by pressing a key, waiting three seconds, pressing the key again, waiting three seconds, pressing the key a third time and about 60% of the time (no rhyme or reason for why sometimes it would work and sometimes it wouldn't) after the third press, it would work.
Now that I loaded the new code, I cannot get this system to work at all. Somehow while playing around, I was able to trigger a single command, but it was after about 40 key presses with misc. waits in between. In addition, I was unable to reproduce the effect.

I do not know if any of this is making any sense, but as usual I really appreciate all of the help!!

Julie

Rob,

Did any of the information from the "learned" download of the 9910 lead to any clues?

Julie

Nope, those are very standard looking NEC1 signals.

Okay, here's a quick variation on what Rob was trying:

12 13 31 80 15 F6 B8 01 17 08 08 01 A6 03 1C 69
78 56 06 CC 02 08 01 01 03 DB E6 5B 3C 02 5C 97
5D 05 7F 7F 3C AE 73 57 5D 17 22 10 D0 13 A7 5D
04 E6 5B 80 0C A9 80 45 5E 85 5E A9 80 45 5F 85
5F B7 5D 03 3C EE 7E 07 5D 20 77 5D 04 22 09 90
19 37 5D 02 22 00 97 5D 0F 22 00 3C C0 7E 44 5E
3C 01 6B 22 06 90 03 60 4F 7F 2F 7F 4C 00 FF

Only the first two bytes are changed, but that affects the length of the On and Off pulses that make up the IR signal. If this doesn't work, I have another idea to try, but it will be a little more involved.

AAArrrrrgggggghhhhhhhhhhhhhhhhhhhhhhhh!!!!!

This is so fustrating!. I tried the new code posted by gjarboni and was able to get the supradic control back (where I press a key, wait 3 secs, press again, etc.). It works just fine via IR (from the remote), but not from the command center.

If you are still willing to spend the time, I'm ready to get "more involved", just let me know what to do with this crazy device.

Thanks again,
Julie
