Seems I remember a post recently where Jon said he was going to be gone for a week. Therefore, you may want to page John.

The lutron dimmer I have is called the The SP 600 with 3 functions on/off
brighter and dimmer.I'm hoping that it's the one that you're trying to make work.And to the learned question yes it worked using CD(1s,2s and 3s)which is where I learned them to.But that remote is not a 740chip.
Thanks BigD |

Okay, I've looked and translated the S3C8 Lutron protocol and I have one basic question.
The decodes the BigD has posted have three 8-bit bytes and a nibble, but the protocol has 4 device bytes and 2 command bytes. When I decoded the S3C8 protocol using protocol builder, it says the device and command bytes are 8 bits. So it seems that the protocol would send out 48 bits, not 28. What am I missing? |

Okay, I did a bunch of decoding and think I understand now. Lutron uses two fixed bytes and one variable byte. The first fixed byte is always 88h. The second fixed byte can be either BD,82, or BE. The byte that is used is determined by the second command byte (00 means use BD, 01 means use 82, 02 means use BE). So what's sent is:
88
(BD 82 or BE)
(Command)
(four zero bits)
BigD,
Assuming all this is accurate, the following should work. When I learn the signals from my 8780 they match the learned signals you sent out exactly.
Paste these into IR and fire it up. Let us know how it goes.
Thanks,
Jason M.

It works,it works,it works,I'm so happy. My 8781 now runs everything.
Thanks for your excellent work Jason M and everybody else who brainstormed to break the mystery code that is 'Lutron'.Thanks again BigD |

I just uploaded a new Lutron SP-600 file that includes both the S3C8 and P8/740 custom protocols. Hopefully, the next person that needs this will be able to use it successfully (unless they have an M6-based remote). _________________ Mark |

Excellent! I'm glad we finally got this nailed down. One last question -- could we have the model number of the dimmer that you have? It appears to use a different Power command than the original Lutron SP-600 file (the original power is hex 2B 01, your power command is 1D 01). I was just about to upload a new file when I realized that your model might be different.
Also, you could try out the other lutron commands (for scene settings) in the files section. It's called Lutron-cdmike... (or something like that).

The Lutron I'm using is called Spacer SP 600-HT
http://www.lutron.com/spacer/singlelight.htm
It's a wonderful little unit for a home theatre allowing dark or as bright as you want from a tiny remote or now an URC 8781 with the power button
returning your lights to brightness you last used it and nice slow dim or bright just like a movie theatre.Thanks Again Darryl aka BigD |

You're quite welcome. If you could do me one favor. I want to see if your dimmer has a new power command or whether there's a new button on the remote. If you could load this upgrade:
Upgrade Code 0 = 42 55 (CD/0597)
E7 00 38 81 88 BD 82 BE 22 01 14 01 1B 01 2D 01
2D 01
End
It has the old power button on the TV/VCR and Enter buttons. Could you try them and see if they do anything?
Thanks,
Jason M. |

Yes Jason they work as power buttons which is kinda weird having 3 power
buttons.Darryl aka BigD |
