Plex Player Remote

alanrichey · Post by **alanrichey** » Sat Oct 30, 2010 2:41 am

I have been asked to build a remote for the Plex Player as someone has uploaded it to the Harmony database.

IRSCOPE/DECODEIR don't understand it, and I must admit I have never seen a case like this where the OBC code is the same for multiple buttons.

I have uploaded the ICT for a number of buttons at https://www.hifi-remote.com/forums/dload ... le_id=9074 Before I spend a long time (there are lots of buttons) could someone take a look at them to see if they make any sort of sense ?

When decodeIR doesn't recognize a protocol, its not that unusual for the OBC's to be miscalculated.

In this case, a quick look at the MISC column tells me that this protocol is not very simple.

Edit: I had an analasis of the Misc column here, but then I looked at the picture in IRScope, and I can see that the MISC column does not match the picture, so I need to use ROB's new tool to convert the IRScope UEI Learn format into an IR file so I can make use of the Timings Summary.

A couple of the learns were bad, they are missing the first part of the signal, but this is fixed data so we can assume that this will be the same in the other signals. Alan has explained to me before that the harmony database is made up of learns.

Vicky, could you post your IR file please, to save me having to re-create it.

Post by **vickyg2003** » Sat Oct 30, 2010 11:28 am

Sure, here it is. Your tool really made this easy!

Hi Rob

No luck I'm afraid, user reports it didn't work. I got him to do some learns at http://remotes.slingbox.com using the original remote and analysed them, but they just confirmed the signals I was getting from my Harmony were correct.

I guess that's it ?

Post by **The Robman** » Sun Oct 31, 2010 1:48 pm

Nope, it means I need to sample the signals generated by my protocol to confirm if they look like they are supposed to. If they don't, I'll fix them.

Post by **The Robman** » Sun Oct 31, 2010 2:04 pm

I found the problem, I had the wrong leadout selected. To fix it, select the protocol code and change "87 04" to "87 44"

43 89 41 8B 12 87 44 08 00 01 13 03 25 01 13 00 FF 4C 2C 11 94 08 B6 08 07 18 C0 F0 C1 56 C0 F0 56 C1 F0 44 C0 05 44 C1 06 8D 01 46

That was what it was already.

User has now lost interest as he has managed to get a fully working remote through http://remotes.slingbox.com. So if we carry on now it's purely for an intellectual exercise

Post by **The Robman** » Sun Oct 31, 2010 3:24 pm

It's wasn't, it was "04" before and it's "44" now. With the "04" value, you don't get an ON prefix to the leadout time, with the "44" value you do. That's what I had to fix to get the code working.

Please remind him that when he asks for help, and experts jump in and provides that help, the least he can do is complete the process by testing the upgrade.

Ah, I understand now. I hadn't realised you had changed the download link as well as describing the change. I'll tell him to try again.

alanrichey · Post by **alanrichey** » Mon Nov 01, 2010 12:42 pm

Sorry, he reports back it still doesn't work. Any other thoughts ?

Post by **vickyg2003** » Mon Nov 01, 2010 1:44 pm

This is where my Etch A Sketch approach works so well.

The timings are a bit off as seen below.

The timings need a slight tweak so that the images look the same. Timings numbers don't have to be exact, but the picture needs to look the same for it to work.
