8811/Rotel learning difficulties

Post by wagner »

I have a 8811 and am attempting to control a Rotel 985bx integrated amp. The 8811 does not have stock amp codes for Rotel equipment so my first try to smarten it up was to grab the existing Rotel upgrade available in the yahoo JP1 files area. There is a Rotel 995 which isn't the exact amp model, but all the pertinent codes work.

However, a couple of the input selectors are extraneous for the 985bx and I and the existing upgrade is missing the code for the 985bx "Aux 2" input.

Pretty darn close! I can control most of the functionality as is.

I wanted to modify the key layout so I loaded it up in KM and did that no problem. My next step was to use the 8811 to learn that last "Aux 2" input code and add it to my newly created upgrade (based off the existing yahoo JP1 file area upgrade that closely matched the 985bx).

The 985bx comes with the Rotel RR-927 remote. I know how to use the learning funtionality of the 8811 and attempted to learn that single code from the 927 remote. No matter what I try I get the single "learn failed" blink from the 8811.

So, i tried other keys off the 927 after a while and they all seem to work except the input buttons. For example, I can learn the volume keys or FF track, etc.

Any ideas? I wonder how the original creator of the 995 upgrade learned the codes if I can't. He did use a different remote so maybe the 8811 just can't learn them for some reason while his could.

his 995 upgrade file is: here

For fun i tried to extrapolate from the existing EFC codes sequencially, but that didn't work. :)

IR says that I have used none of my learning memory which is correct because I created an upgrade for the learned codes that I had learned for my Rotel CD player earlier.

The batteries in the 927 are new and strong. In fact, while I can't go into another room and switch inputs on my amp with it, I can bounce the signal off walls in the opposite direction and switch inputs. It's damn strong. Almost strong enough to make me wonder if it isn't IR/RF or some such. It won't go through walls though, so maybe it's just a hella strong LED. :)

It isn't a huge loss that I can't select "Aux 2" as it is my VCR and it isn't used that much anymore, but it would be nice to whoop this issue anyway.

Thanks,

Hi Mike,
Rather than trying to extrapolate the codes using sequential EFCs, try sequential OBCs. Use the SWAP button in KM to change the entered codes from EFCs to OBCs, then enter any "gap" OBCs that you spot.

As this upgrade uses the NEC protocol, I'm surprised that you're having problems learning the signals. The NEC is a very standard signal.

If you like, you can send me the remote and I'll see if I can learn the buttons in question.

AN idea - some/most?/ UEI remotes have difficulty learning when you attempt to learn to a device that has been installed via an upgrade. Have you tried learning to a DIFFERENT device than your upgraded one? Any device will do, as long as it's one tha is NOT upgraded.

Or you could go to Rotel's website where they have pronto ccf files for their equipment and decode with DecodeCCF ;-)

Here they are. My guess is all NEC1:131.17 (they might be NEC2:131.17) so use whatever works for your existing commands:
OBC EFC
000 181 Power_Toggle
001 185 CD
002 183 Tuner
003 187 Aux 1
004 180 Aux 2
005 184 Tape 1
006 182 Tape 2
022 118 {Vol+}
023 122 {Vol-}
024 245 Mute
026 247 Zone
027 251 Vol Right_Arrow
028 244 Left_Arrow Zone

This needs some clarification in case it causes anyone undue concern. The Capn is onto something but he has the details wrong.

The older S3C8 learning remotes, which includes the 15-1994 and URC-7800 remotes, have a bug in them which prevents learned signals from working when the device button being used is programmed with an upgrade that uses a protocol upgrade. Normal upgrades (ie, those that use a built in protocol) do NOT cause this problem.

This problem didn't make it into many models and it was fixed by the time the URC-7560 and RCU810 remotes were produced. In fact, the 15-1994 and URC-7800 (and be default URC-6800) are the only remotes that I know of that do have this problem.

Right on. Thanks for all the info and suggestions everybody and for the offer to send the remote to you, Rob, for dissection.

Actually, I did find that CCF file on the Rotel site, but didn't know about DecodeCCF! So, thanks, jon_armstrong for decoding it. I can even program the Zone code which I don't use, but must... have... all-inclusive... upgrade. :)

trips, I did try to learn the codes on a alternate, unused device on the 8811, but no matter what I tried I got the single flash "you are SOL" error.

Great! I'll tidy the 985bx up and submit it and my Rotel cd player upgrade to the group.

Sheesh! Thanks for the clarification (details of which even I was unclear). :oops:

I guess I better stop "helping" before someone gets hurt. :roll:
