Hi,
I've been banging my head on this for hours. Hoping for some help, it'll be greatly appreciated.
I would like to build a fully working controller setup for this device.
I can get everything working from different places except the "Clear Voice" function.

Based on the code that you posted, try sub-device=20, obc=234

In case you're interested, the way I did it is like this, take the hex code that you posted and convert it into multiples of 500, then convert the pairs into binary by converting "500 1500" into 1 and "500 500" into 0. Then separate the binary into 8-bit chunks and read them backwards (ie, LSB). As you can see from the RMDU files, this signal uses the Panasonic protocol.

Here's the hex you posted:
3486 1757 419 450 418 1320 417 453 415 454 425 444 424 446 422 447 421 448 420 449 419 450 418 451 417 452 416 453 415 1324 423 446 422 447 421 448 420 449 419 451 417 452 416 453 415 1323 424 446 422 1316 421 448 420 450 418 1293 444 452 416 1295 452 444 424 418 450 446 422 448 420 1318 419 423 445 1320 417 453 415 1323 424 1313 424 1314 423 446 422 1316 421 1290 447 1291 446 1319 418 451 417 1321 416 454 425 74911
3487 1754 422 447 421 1316 421 449 419 450 418 451 417 452 416 453 415 454 425 444 424 445 423 446 422 447 421 448 420 1318 419 451 417 452 416 453 415 454 425 445 423 446 422 447 421 1317 420 422 446 1319 418 452 416 453 415 1295 452 444 424 1314 423 447 421 448 420 449 419 450 418 1320 417 453 415 1323 424 445 423 1315 422 1315 422 1316 421 448 420 1318 419 1292 445 1320 417 1293 444 453 415 1322 425 444 424

Here it is rounded to multiples of 500:
3500 2000 500 500 500 1500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 1500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 1500 500 500 500 1500 500 500 500 500 500 1500 500 500 500 1500 500 500 500 500 500 500 500 500 500 1500 500 500 500 1500 500 500 500 1500 500 1500 500 1500 500 500 500 1500 500 1500 500 1500 500 1500 500 500 500 1500 500 500 500 75000
3500 2000 500 500 500 1500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 1500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 1500 500 500 500 1500 500 500 500 500 500 1500 500 500 500 1500 500 500 500 500 500 500 500 500 500 1500 500 500 500 1500 500 500 500 1500 500 1500 500 1500 500 500 500 1500 500 1500 500 1500 500 1500 500 500 500 1500 500 500 500

Here is that hex converted into binary:
3500 2000 01000000 00000100 00000101 00101000 01010111 01111010 500 75000
3500 2000 01000000 00000100 00000101 00101000 01010111 01111010 500

And here are the values of the 6 binary strings:
01000000 = 002 (OEM)
00000100 = 032 (OEM)
00000101 = 160 (main device code)
00101000 = 020 (sub device code)
01010111 = 234 (OBC)
01111010 = 094 (checksum)

Jabba, would you be kind enough to build a single RMDU file that only includes the functions that you have confirmed that work on your SC-HTB18, then post a link to the file here?

...there's one other thing if you don't mind...

are you able to work the same magic with this one?

Thanks so much for your help.

I'm glad I was able to give something back.

Excellent, thank you.

I noticed that it uses OBC 61 for POWER, but did you experiment and try 62 and 63 to see if they work for discrete on and off? Every other device that uses 61 for power uses those for discrete power. I'd also be tempted to try some of the other known functions from sub-device code 20 as they tend to be "sound" commands, that might just work on a soundbar.

The bold ones below are from your file.

048 Surround
049 SFC: Music
136 tone/balance
151 dimmer on/off
160 SFC: Movie
174 stereo/2chmix
176 Stereo/surround/SimSurr
178 Dolby PLIIx
179 NEO:6
188 Effect/Level +/Right
189 Effect/Level -/Left
190 level
191 effect / delay
234 Clear Voice
243 center focus
246 Surround test

I ran through all the ODC numbers for sub-device 20 and 00 looking for that clear-voice. I found it just when I noticed your reply!

My workflow involved noting the EFC5 for any buttons that produced a result.

Here's what I found. (all numbers are EFC5)

44208 and 44080 seem to change the remote control code - all lights blink for 10 seconds.

660750, 60720 and 60848 have a similar effect

60742 - I have it noted as affecting the power. (this is ODC 62 device on)

Why are you working with EFC5s? How are you testing them? Are you entering in all the EFC5 codes manually? The easiest way to test them is to enter the OBC and sub-device codes in RM and test them via an upgrade.

Here are the codes that you mentioned:

EFC5 - sub - obc - the function it should be
44208 - 20 - 81
44080 - 20 - 80
60750 - 0 - 46
60720 - 0 - 80
60848 - 0 - 81
60742 - 0 - 62 - discrete on

Try 60870 (sub 0, obc 63) to see if it's discrete off.

I don't have obcs 46, 80, 81 listed in any of my charts, so I don't have any knowledge on what they're supposed to do.

Btw, the term is OBC (Original Button Code), not ODC

Apologies for any confusion caused. I was doing like you said with the OBCs but writing down the EFC5 code to note when something happened after I pushed a button.

In an attempt to pull all this together for completeness I've gone back and tested some more with those interesting numbers.

EFC5 - sub - obc - the function it should be -
44080 - 20 - 80 - sets device to remote code 1
44208 - 20 - 81 - sets device to remote code 2

60720 - 0 - 80 - sets device to remote code 1
60848 - 0 - 81 - sets device to remote code 2

This functionality is explained in the manual pg19 here:
https://www.panasonic.com/content/dam/pim/au/en/SC/SC-HTB/SC-HTB18GN/Sound%20Bar%20SC-HTB18%20Operating%20Instructions.pdf

I also checked this on sub 28 and the OBCs 80/81 have the same function.

I did not get the any results from the discrete power function codes. I'm unsure why this time around - probably error on my part.

I went completely (0-255) through subs 0, 20 and 28 and didn't find any other functionality beyond the 80/81 change remote code codes.

Regards,

Jabba

It would be nice to know what remote code 1 and 2 look like. If you still had the OEM remote, once you followed the sequence to make the unit respond to code 1 or 2, presumably the OEM remote would start sending that signal too. To replicate that with a JP1 remote, we'd need 2 more upgrades.
