Posted: Mon Nov 08, 2021 7:17 am Post subject: Musician Monoceros preamp remote help needed |
|
|
Hello guys!
I have a Musician Monoceros preamp for which I don't have the remote, unfortunately.
By an incredible luck I have managed to get one IR code for POWER_DOWN. Basically, I saw that when my Samsung TV gets a new HDMI input, it sends some IR codes and one of them turns off the preamp.
I intercepted that code using a RPI and IR transceiver. Encoding is MCE and by playing a bit with irScrutinizer (D, S, F, T values variations), I managed to find some more codes.
However, I did not manage to find VOL_UP code and I am a bit stuck now. Of course, the most important functions are VOL_UP and VOL_DN.
I have to say that my knowledge regarding IR transmission is limited.
Here is what I have at the moment:
I am hoping that more knowledgeable people can help to find the VOL_UP code.
These 2 work perfectly as single commands:
VOL_DN: MCE: D=38 S=126 F=84
POWER_OFF: MCE: D=38 S=125 F=84 T=1
These 2 only work together as following:
(PREV_SOURCE + DIM-) do exactly what their name suggest, change the source and dim the display. They do not work as single commands. So, if I send (PREV_SOURCE + DIM-) the source is changed and display is dimmed. If I send another PREV_SOURCE, the source will change. After this, if I send a DIM-, the display will be dimmed and so on.
PREV_SOURCE: MCE: D=38 S=119 F=84
DIM-: MCE: D=38 S=119 F=84 T=1
I have tried all 512 combinations of S and T, while keeping D=38, F=84 and none of them managed to give me volume up.
Could it be that the device is working on a different IR encoding, but somehow reads MCE encoded signals?
I have also tried different variations of the RC6 IR protocol and none of them have interacted with my device.
Do you have any idea that I could try for finding the volume up code?
Thank you in advance,
Fabian |

Interesting, the Function code (F) is normally different for each button, it's the D and S values that should remain constant. Also, this signal has a toggle bit built into it (ie, the T in your decodes), so that might be why certain signals only work when sent in the right order, because you manual signals are not setting the toggle correctly. In other words, if the previous signal set the toggle as 0, your device might require the next one to have it set to 1, etc. _________________ Rob

Hi Rob,
Thanks for your reply.
After a few weeks of trying I managed yesterday to crack the volume up button.
The catch was that irScrutinizer was identifying the signal as MCE, when it actually is RC6-6-32. MCE D38 F84 S126 is exactly the same as RC6-6-32 D38 F84 M6 OEM1:128 OEM2:126. S from MCE goes to OEM2 from RC6-6-32. In case of MCE, OEM1 is fixed at 128 and M is fixed at 6.
Basically, what I did to find the volume up code was to play around with OEM1 from RC6-6-32 and voila, volume up is now working. |

Could you type up a list of the codes for all the functions that work? _________________ Rob

I was actually hoping for something like this, only with all the buttons that you found:
Code: | VOL_DOWN: RC6-6-32 D38 F84 M6 OEM1:128 OEM2:126
POWER_OFF: RC6-6-32 D38 F84 M6 OEM1:128 OEM2:125 T=1
PREV_SOURCE: RC6-6-32 D38 F84 M6 OEM1:128 OEM2:119
DIM-: RC6-6-32 D38 F84 M6 OEM1:128 OEM2:119 T=1
VOL_UP: RC6-6-32 D38 F84 M6 OEM1:128 OEM2:??? |

Hi Rob,
I only have these 2 codes fully working:
VOL_UP: RC6-6-32: D=38,F=84,OEM1=129,OEM2=126,T=0
VOL_DN: RC6-6-32: D=38,F=84,OEM1=130,OEM2=126,T=0
POWER_OFF: RC6-6-32 D38 F84 OEM1:128 OEM2:125 T=1
is also working. |
