JP1 Remotes

Hello.
Does anybody know of how to update this device by JP1 cable?
This cable is good working with DB 7000 keyboard and remote control (URC-39730B02-00) but it's unpossible to connect it with the new one. IR software says "No response from Remote".
The unconnectable RC is normally working and can be easy programmed via it's keys.
May be there are the blocking keys or some blocking functions?

Please, answer, if you know anything.

Can you see any label near the 6-pin header, like JP1 or JP1.1 or JP1.2?
If you have a digital camera you can take photo of the PCB component side and post it here.

I have JP1. I wonder - this is the same protocol like I have on another working RC. And I shall make the snapshot.

I would like to find out the answer to this one also. I cant get this remote to read either with known working cables. Mine also says JP1.

Have you tried this?

Yep tried all of that. This remote just doesnt want to be read.

Sorry, no idea. I suspect it's likely NOT a JP1 remote. You may have to tear it apart and take some pics and post them to see if someone can identify it.

If you have the remote open, look at the PCB to see if you can find an EEPROM. An EEPROM is a small rectangular chip with 8 pins (4 on each of 2 sides). The PCB label is usually "U2". (The spot could be empty, in which case you would need to add an EEPROM to use JP1 with the remote)

Take a look also to see if you can find the main processor, this is usually labelled "U1" on the PCB. If it's hidden under a black circular glob, it's probably the traditional Samsung S3C8 chip, in which case you should have been able to find the EEPROM (or at least an empty spot for it) if there's a 6-pin connector. If the main processor is a visible chip, tell us what's written on it (you may need to peel away a UEI sticker).

If you find a visible chip but cannot find an EEPROM, you could well have a JP1.1 or JP1.2 remote, and we'd need to know what's written on the chip to tell you which it is. If it's an SST chip it's JP1.1, if it's a Motorola chip it's JP1.2. If it's JP1.2, we'll be publishing the info soon on how to communicate with these remotes, but it will require a new JP1 cable. If it's JP1.1, we don't have an expected date of when we'll be able to work with these.

That reminds me to see if I can figure out the "macro" option of my digital camera well enough to take some pictures of the broken 8820 I got from Rob (for comparison in situations like this thread, not because I think the problem could be spotted in a picture).

Your pictures (I assume without the "macro" option of the camera) are too blurred to tell me much. But subject to that limit, the chip and the way it is covered in black looks just like the one on my 8820 (a JP1.2 remote). JP1 remotes that I recall looking at have an even more severe covering over the chip, so that many of the circuit runs near the chip are covered as well.

The fact that the remote was made in 2004 and there's no EEPROM on board seem to indicate that this is a JP1.1 remote.

While I am hopeful that we will be able to leverage the work that we're doing on JP1.2 remotes to support JP1.1, I don't know for sure that it will be possible.

I just got word from UEI that this is a JP1.2 remote, so hang in there, we'll be making some announcements pretty soon regarding JP1.2
