If we were to properly add the protocol to KM, we would have KM calculate the final bit, likewise for RM, but when you're using "Manual Settings" you need to calculate the bit in advance, as you did.

Now its up to the slingbox people. |
Thanks to all the senior experts whom help to create a match. I transcribed their results with the JP1 tools to create the respective files.
BIN file Instructions.
Customization instructions:Btw, the upgrade only has 34 of the 43 functions listed from the LHD. The following commands are missing; Archive, Help, iTV, Option, Record, Search, Select/Ok, Teletext, and TV/Radio.

Thanks, Rob. I've appended the missing commands in v1.1 of the aforementioned upload.

I sure am glad that Rob supplied those, because I went back to the ICTs to try and dig them out and even knowing the pattern, it was too confusing for me to do, even though some people some people might say "once we've decided to try phase shift keying as a candidate decoding, the rest follows pretty easily." It will never be an easy protocol for me!

I take it that we can't use the true OBCs unless the protocol is modified to use them or if we find a built-in executor that addresses it.

Haha. That was snappish but in a cute and funny way.

Vicky,
You'll notice that I didn't supply the OBCs--it's a lot of work when done manually, even if one does know the IR protocol, and I didn't go to the trouble. It is easy for me to decode a biphase from the graphs in IRScope-- Just look for negative going or positive going edges at every 2 units. But this quad phase protocol staggers the timing around, and I can't decode it from a graph at all.
By "the rest", I meant the details of the IR protocol, not the OBCs. |

It wouldn't make any sense to modify the protocol to generate the checkbit. If we were to ever fully support this protocol what we would do is add logic to RM and/or KM so that the program would generate the checkbit.

| Well Dave all I can say is thank you. This thing has been bugging me on and off for more than a year! I am so glad its cracked. I feel like a celebration is in order! |

Here's what I did...
1) Open the ICT using IRScope, select all the buttons and export in UEI mode.
2) Drop the export into my converter spreadsheet and create an IR file
3) Open the generated file using IR, set the rounding to 105, and click Times Summary
4) Then I pasted the Times Summary data into a new spreadsheet. I used the SUBSTITUTE function to convert all the times to multiples of +1 or -1
5) Then I started another tab where I brought all those +1s and -1s in in blocks of 12 bytes (eg, "+1 +1 -1 -1 ").
6) Then I started another tab where I converted the known combinations into 00, 01, 10 or 11, and from there I could extract the OBCs
Here's the XLS:

Ah, okay. Thanks for the explanation. The other thing I was going to ask is whether or not the Samsung SMT-C520, which is represented in this thread uses the same protocol? And if so, is it possible to decode the OBCs to empower me to create an upgrade for it too?

Good call, it does indeed look like the same protocol, but the learns in that ICt are as bad as the initial learns posted in this thread, so they're not good enough to get code data from them.

Okay, cool. I'll wrangle up some learns for you. After all, my milk shake brings all the boys to the yard. Totally don't know what that means but thought I'd throw it in there for funsees.
