I have a OFA Producer 8800. I was adding advanced codes to control my new Home Theater set-up and I just started to get this message. What is the memory limit on this remote? I have a few devices on it but I don't believe I have all that much. I know there is a JP-1 mod that I can do but I didn't think I would need it. The method I have always used is after I determined the device code, I would (hack) the 255 advanced codes for what I needed it to do. There were a few instances that I needed to use more than one device code to operate a device and if I rem all I had to do was program the adv. code I wanted with one device code and then merely change the device code for the other advance codes I wanted. I am saying this because it seemed to me that since I could get the remote to do anything I wanted, the JP-1 mod was unnecessary. I really didn't study that JP-1 mod because I didn't think I needed it and it seemed a bit confusing. Do I need it to solve my lack of memory problem? I actually think that something I did grabbed all the memory rather than me actually using it but that is just a guess and it would be a real pain to clear out the unit and start over only to find out that the memory is that limited and I need to do this a different way.

You only have anough memory to program about 45 keymoves, and macros use the same portion of memory, so if you have macros, you get less memory for key moves.

With JP1, you can create new upgrades with the buttons laid out exactly how you want them, drastically reducing the need for key moves. Plus, on many occassions, you can create combo codes for the devices that need more than one setup code.

While JP1 can get really complicated if you decide to dive into the advanced stuff, it can also be really easy if all you want to do is load your code and go.

Hmmm.. If all I can program is 45 keys total for the unit that must be the problem. I know on this model the "learn" keys use a different eeprom, so I have 2 different memory banks. I guess I'm gonna have to dig in to the JP-1 issue, seems like your sayin that will give me more room for what I need to do. I haven't done much of the key move thing- I'm just changing what was programmed there or adding a feature to a key that serves no other use. Just to be sure are you actually stating that using JP-1, I will be able to program more device (advanced codes) on the remote than the method I am using now?

what he's saying is there is a portion of memory devoted to "upgrade codes" that you aren't using at all. By building new device upgrade codes you can include a lot of what you're doing with keymoves, thus giving you more keymove space. The upgrade section of the eeprom is very considerable in size. I have 7 device upgrades in my 1994 and still have almost half of that area left, and just 4 keymoves.
Just recently, I think it was Rob who found a hardware "hack" to finally be able to READ the memory contents in the memory eeprom through JP-1. However, I haven't read how large that eeprom area is, if it's all devoted to learned signals (or only part's actually used), and if you can write to it, or any unused portion (if any is available). Maybe Rob can expand on this.
Most ueic learning remotes can learn about 20-30 signals. Whether the P-8 series (with a seperate eeprom for learning) can learn more than that I don't know. Since it's an 8 device remote and it has 6 dedicated learning keys, I assume a max of 48 or less. I haven't seen any documentation on it, but then I don't have a P-8 so really didn't have a personal need to dig into this.
I can say that recently, the JP-1 group has picked up a member with extender writing skills and has devoted time and effort to make extender's for the 740 chip remotes (Like the P-8). So that is a definate plus for P-8 owners to use JP-1.
I'd say there is a great deal of incentive to use JP-1 for P-8 owners. All that's required is the cable (kit is 10.00; premade 18-20)and the free software available at the JP-1 yahoo group; a windows based machine, and excel.

The URC-8800 has exactly double the "learning" memory compared to remotes like the 15-1994, because it has an entire 2k EEPROM chip dedicated to it. I can read the learned memory from my URC-9800 because I did a hardware hack, but the only purpose of this hack is so that Producer 8 users can learn signals from their original remotes so they can figure out the code info to build an upgrade.

Like Jim said, primarily, you won't use JP1 to give you more keymove memory, you will use it to make better use of the upgrade section of the memory, although you can actually increase the size of keymove memory section with the Producer 8 remotes, something we can't do with the 15-1994, etc (at least, not without installing an extender, but that's another story).

Rob,

I think I saw someplace that "shift" functions use a different area of the eeprom. Can programming some of those keymoves to shifted buttons free up some keymove space, or are those within that general block known as "macro/keymove area"?
Jim
Oh yeah, you said the P-8's have double the learning room as other ueic remotes. Others have roughly 1022bytes dedicated to learning. If the 1st eeprom isn't used for learning where does that 1022 get used for? Or does the P-8's have more keymove and device upgrade memory than most other ueic remotes? I'm assuming from your reply that the P-8's have 2 2K eeproms.

It seems that doing the JP-1 mod will allow me to make a new dev code, that I've created, with the keys allready set the way I need/want them. I also read that it is possible to increase the memory in the keymove section of the 8800. How can I do this? I also read here that a "shift" code might be possible when the regular memory store is full. Is this true? I also have to BIGTIME thank Robman,Johnsfine and the others (sorry I can't rem all of the real innovators) who took their time working on a hobby/challenge to provide me with a remote that has been able to control all that I've ever needed in the past. I've been using one of these starting with a OFA 6050 then a 7200 forward to a 7800 and currently the 8800 for a few years now. I originally rem calling a OFA tech support line that faxed me instructions on how to program device codes and advanced codes, then I lucked on to the starbase and hi-fi sites which dramatically improved my ability to customize my remote. I rem getting the 8800 as a gift and putting it in a drawer because the book didn't say anything about advance code programming. Some time later (duh) I revisted the hi-fi/starbase sites and voila' that 8800 came out of the drawer. I would never have used it if it weren't for the people here who have spent untold hours on a hobby. Like I said a BIGTIME thanks to you all.

"I also read here that a "shift" code might be possible when the regular memory store is full. Is this true?"

The shift code does not move anything, you won't get any more space using it. It works more like the shift key on your computer keyboard, changing the code that the remote sends. Unlike the computer keyboard, the shift codes are not predefined, you determine if you want them and what they are. The Setup button is pressed before the button that contains a shift key to make the remote send the second code instead of the normal code.
