JP1 Remotes

First off thanks to you all for the amazing work you have put in over the Years. Special thanks to binky123 who constructed the RDF and put up with my inexperience.

The Humax remote was a bit tricky as it needed the JP1 connector to wired in and then the remote did not have macro or keyswap support ...

Well I seem to have hit a bit of a brickwall...

I have tidied up the RDF, added buttons & a partial & possibly incorrect button map? Have dropped in protocols & Digitmaps from a URC-7950 and added a few valid Setupcodes.

RDF is here

Bit more progress. Please bear with me as this is the first time I have done any of this....

VPT codes are all working

Added 2BytePID and the device codes are now correct
Added Setupvalidation = warn & a small selection of valid setup codes & I can now change the setup codes

I have also put in ...

Thanks Rob

It's allowing download and upload. I will have a play with the other settings that I "half" understand and see where I can get to.

Duh... silly me, I have been playing around with too many SKY JP1 remotes. Moved the 4 & 6 wires to pins 30 & 31 and we get data. Nice of them to make the TP numbers line up with the JP1.3 connections. :)

Signature is 31613161 which is not recognised.

No JP1 connector but I opened it up and it has a Samsung 3F80 Chip.

Looking at the Test points these connect to.

TP2 ...

As you are testing. Is it reasonable to assume that the interface & chip comms protocol is now fully understood?

Look forward to further updates.

Thanks Rob, some posts seemed to indicate it was a lost cause, & others that there was hope.

If I can do anything to help, I have a logic analyser etc, then let me know?

Am new to remotes, but not to reverse engineering & reprograming.

Hi Guys

Been lurking for a week or so, still finding my way around. Prompted by ditching Sky here and having a collection of various vintages of Sky remotes, I Built a USB 1.3 interface & that's working fine with a URC-7556 & a URC-1660 that I also happened to have. :)

So the latest Sky remote I ...
