JP1 Remotes

One thing's for sure. There's absolutely nothing we can do about this in terms of modifying either the interface or the remote itself.

Long time since I have been here, I'm having trouble opening an URC 11-6810 remote that is built for combat that is in need of a sticky membrane cleaned ...

It was not obvious to me when the COMBI mode was turned on. I found you can see it work when you press the keys (if you press the mute and previous channel buttons they are on the different modes) and it lights up the relevant mode and the combi lights together. As I mentioned my macro does not work ...

Hi 3FG,

Thank you. I have a working setup.

One of the problems was this weird combi-control that the remote supports that does what is similar to volume punch through. It takes the TV volume, aspect and AV and controls it in SAT mode. This is kind of OK but something is not quite right (and I ...

Hi,

I had similar experience. Compounded by not realising my one remote was a JP1.4 and the other remote has a partially scrambled program so not sure if it is working.

I have recorded most of my experiments in the post at

Update on the older remote with my new USB to serial (TTL) converter.

My new USB to TLL converters arrived from China. They have a Silicon Labs CP2102 chip as opposed to the FTDI that is recommended and the MCT Corp ones I have that do not support the TXD BREAK signal. I had to connect the reset ...

Hi Tommy,

Update, I decided to force the new URC-2981 remote open, not too bad, start from the bottom, it says, would you believe it JP1.4 next to the connector :-( the rest of the text as follows.

Hi Tommy and others,

I had a hour to relax with my laptop again and decided to see if the pin 5 wire might indeed have had something to do with the problem. I pulled it out even though it is only 2 inches long as the instructions are to cut it close. Still no change. I then downloaded realterm and ...

Hi Tommy,

I was using the converter again 2 days ago to do testing on some other industrial automation systems successfully.

I did a quick pin 2-3 test now using ComTest and it works perfectly.

As mentioned in my first post the 9V JP1 interface loopback was also successful and I have checked ...

Hi Tommy,

Not sure of the file name as I printed the first PDF page out. It was two pages, one with transistors, one with an IC. The title says

Hi Vicky,

The PCB has the code URC 11-7950 R00 which leads me to believe it should be compatible with the URC7950 and this is listed as a JP1.3 in the spreadsheet.

It also looks like the URC 7930 and URC 7950 'Comfort Line' that are for sale on Amazon with the URC 7940. The PCB has some components ...

Dear All,

A lovely forum and a lovely community and tools.

About 2 months ago our One4All remote started to malfunction (power button sends code in different protocol only in SAT mode all other buttons still work). After searching I found out about JP1 and saw the remote had holes in the battery ...
