Dave, could you make a similar file using the Nevo C2, because that would use S3C8 code which I can read?

Ok, never mind, TV/4485 looks like a winner, as the binary appears to match what I found.

Carl, could you learn the same Epson button to 4 or 5 different 8820 buttons please, and don't do any additional presses of the Epsom button in between.

The reason I ask is because the binary from the UEI upgrade doesn't exactly match the binary that I got from your learns, and there are 3 bytes of data per button, which is way more than they need, so I'm wondering if there are any toggle bits or anything similar in there.

Here it is, in case you still need it:

This protocol has some similarity to DirecTV, but is simpler.
DiIrecTV starts {38k,600,msb}<1,-1|1,-2|2,-1|2,-2>, while Rob's decode starts (I think) 38k,572,msb}<1,-1|1,-2|2,-1|2,-2>. In other words, except for 600 versus 572 uSec, the durations for the signal bits follow the same pattern. In writing a HCS08 executor, I'd probably want to first look at the DirecTV executor.

Here you go:

Key 1 to 6 = Epson Menu button
Key 7 to 9 = Epson Discrete power on button

Here's a picture of what the remote looks like:

What's the signature of that remote, is it 30333033? If so, that's a S3F8 remote, which means it can use the executor that's in the last file that Dave posted, which means I can build you an upgrade to try out.

Rob, Carl says it is a JP2 remote (presumably the 1056B03). Here's the output from my MAXQ JP2Executor program:

    16 D3 D3 FE  AND        DCbuf3,      DCbuf3, #FEh
L0: End Signal Spec Code Block

So it sends 26 bits: 2 from the fixed data, and 8 each from the command bytes. The least significant bit of the 3rd command byte is inspected to determine if the lead out should be 75 or 31.6mS. This LSB will always be set to zero before transmitting. I suppose that this is structured as 2 bits of unit code, and 23 bits of variable info.

I have tried the TV/4485 upgrade in my JP2 remote and it is not working.
My signature was 2010A9MAXQXX
Processor: Maxim MAXQ610..

The good news is that, I have a JP1.3 remote on hand with the signature 30333033:

Let me know if you want me to try something.
I still need an upgrade for a URC-8820 but for testing we can use the Atlas 30333033.

Can you post the RMIR file you used to test?

Try this upgrade on your Atlas:

I can confirm that the upgrade is working with the Atlas, I have tested all the keys.

How do we go from here to make it work on a URC-8820?

When I get a chance, I will create an upgrade for you that is based on the binary found in your learns, just to verify that those also work. The reason being that only a handful of buttons had the same binary between the UEI upgrade and the captures, the rest had different binary, so I want to confirm that 2 different binaries work the same function.

Thanx alot Rob.

Posted: **Wed Feb 24, 2016 10:32 pm**

Here ya go, this one has all the codes from Dave's upgrade and all the ones from your learns. Where the binary was the same, I labeled it as such.

Primarily there are 2 sets of arrow buttons, the official UEI codes are assigned to the regular arrow buttons, and the learned arrow codes are assigned to the transport keys. Look at the layout or buttons tab in RM and you'll see.
