I just recieved my Cinema 7 and for the price I love it. One exception is the fact that it does not control my Satellite reciever properly. I can channel down but not channel up and the only number keys that work are 2, 4, 5, 6, and 8 (note that that makes a plus on the keypad) is there any way around this?

What device code are you using?

0566

The advanced codes for 0566 are on my web site, so you can program any buttons that aren't working right.

I suspect that the codes for the menu arrows that are shown on the list on my site may be incorrect, maybe you can confirm this, I think the correct codes are as follows:

200 (up)
128 (left)
120 (right)
208 (down)

I also found a couple of codes not on the listing:
251 "A/Ch"
226 "Guide"

Let me know if these work for you

Well, It looks like they don't work for me . . . at least the first couple. I did manage, however, to "learn" the codes. Thanks I have found your site as well as this site EXTREMELY useful and I thank you very much.
Also the Yamaha receiver codes worked perfectly.

What is the exact model number of your RCA

Chris,
I had another look at the codes and it does look like the codes for the numeric buttons are wrong.

Try these codes and let me know if they work, if they do I'll change the listing:

"1" EFC = 139
"2" EFC = 163
"3" EFC = 155
"4" EFC = 115
"5" EFC = 107
"6" EFC = 131
"7" EFC = 123
"8" EFC = 211
"9" EFC = 203
"0" EFC = 147

"On" EFC = 227
"Off" EFC = 219
"Info" EFC = 179
"Src" EFC = 234
"A/Ch" EFC = 251
"Menu" EFC = 082
"Guide" EFC = 226
"Up" EFC = 200
"Left" EFC = 128
"Right" EFC = 120
"Down" EFC = 208
"Who" EFC = 009
"Audio" EFC = 143
"Exit" EFC = 002
"CH+" EFC = 043
"CH-" EFC = 051

Rob.

I also have the RCA 4280 (dolby digital) DirecTV satellite receiver and have been experiencing the same problem. I did some experimentation trying to find the advanced codes, but the only codes I find are the ones that already work for device code 0566.

As Christopher noted, the Down and Left buttons work, 0,2,4,6,8 work, but the odd digits, Up, and Right buttons do not work using the default settings for 0566, or by entering the advanced codes listed above.

Other notable differences from what Rob has listed:
"Off" EFC=099
"Src" EFC=??? (assuming the button labelled Antenna)
"A/Ch" EFC=??? (labelled Go Back)
"Who" EFC=???

If anyone has any of these missing/corrected codes I would appreciate the help. Does anyone have any suggestions on other things to try? Is it possible that I need to use a different device code for the buttons that aren't working?

Ok, I just did an exhaustive search (tried all 256)through all of the advanced codes using device 0566. NOTHING does CH+, Right, or 1,3,5,7,9. These all seem to be "complements" of buttons that do work...do you think these all work on a different device code? Has anyone come across something like this before?

I looked in a CCF file to get the function codes for an RCA DSS. They are listed below, about the same as what Rob listed, but I have listed the "true" function code (what the remote actually sends) before each EFC code.

It sounds like all the ones you can't get to work have a true function code that is odd. Is that correct? Do ANY functions whose true code is odd work? What about CH+ ?

You said "Off" is 099. Is that really an On/Off toggle?

Device 0143 is the same protocol and "true" device number as 0566. Its button assignments are different. I don't know whether its EFC numbers are different. I wonder if you have some subtle timing problem that drops the low bit of the true function. Maybe 0143 has different timing than 0156. Try a few EFC numbers in 0143.

Your theory is correct, NONE of the functions with odd "true" codes (is this the same as OBC?) work. (I am able to "learn" them however)

099 is an On/Off toggle. 227 is On only.

I just looked over my OBC->EFC table, and the only working code that has an odd numbered OBC is "Audio" that Rob listed above. That code works fine. Interestingly, that is the only code I have found that isn't on the original remote.

I just tried some experimentation with device 0143. All of the EFC codes that worked with 0566 work, but I haven't found any codes that didnt work with 0566.

It sounds like you are onto something with the theory that the LSB is being dropped, possibly because of timing. Does this mean I am out of luck with the Cinema 7?

As a side note, I also have an X-10 Universal Remote model JR20A, and the Sony remote that came with my Sony WEGA TV. They both successfully control my satellite receiver after programming in the correct device code. I'm not sure if all of the functions work, but CH+/- and all of the digits definitely work. That leads me to believe that the receiver definitely can be controlled by a universal remote and RCA isn't doing anything too tricky.

Hey Josh,
What device code are you using in the X10 remote? I think my R/S 15-1924 uses the same codes. If I can re-create the true RCA codes, I can test them to see what they look like and hopefully find an alternative device code that might generate them (using a file that John Fine created).

Rob.

Im using DSS Code 065 on the X-10 remote.

And to be thorough, on the Sony TV (KV32FS12), satellite codes 802 and 808 seem to work equally well.

I appreciate your help.

Thanks Josh, code 065 does work on my 15-1924 and it has helped me solve the problem. Could you try an experiment for me.

Try pressing one of the buttons that doesn't work (the number 1 for example), but hold your hand over the IR window when you start pressing and then uncover it and see if it performs the correct function on your DirectTV. This is hardly a long-term solution, but it might help prove my theory.

John,
It appears that the OFA device code is using too large of a lead-in ON time for the first repeat of the signal, but is using the correct time for the remaining repeats.

Here's an example of the correct signal (for the number 1 button) as recorded by the Pronto:

0000 0047 0000 001A
00E2 00E2 001C 0037 001C 0072 001C 0073 001C 0072 001C 0037 001C 0037 001C 0073 001C 0072 001C 0037 001C 0037 001C 0037 001C 0072 001C 0073 001C 0037 001C 0037 001C 0037 001C 0073 001C 0072 001C 0037 001C 0037 001C 0073 001C 0072 001C 0073 001C 0037 001C 01ED

Now, here's the same button on the Cinema 7:

0000 0048 001a 001a
0477 00e6 001d 0039 001d 0072 001d 0072 001d 0072 001d 0039 001d 0039 001d 0072 001d 0072 001d 0039 001d 0039 001d 0039 001d 0072 001d 0072 001d 0039 001d 0039 001d 0039 001d 0072 001d 0072 001d 0039 001d 0039 001d 0072 001d 0072 001d 0072 001d 0039 0037 01cc
00e2 00e6 001d 0039 001d 0072 001d 0072 001d 0072 001d 0039 001d 0039 001d 0072 001d 0072 001d 0039 001d 0039 001d 0039 001d 0072 001d 0072 001d 0039 001d 0039 001d 0039 001d 0072 001d 0072 001d 0039 001d 0039 001d 0072 001d 0072 001d 0072 001d 0039 0037 01cc

The Pronto has recorded it as a one-time signal followed by a different repeating signal. The lead-in hex on the first signal is "0477 00e6" whereas the lead-in hex on the repeating signal and the original RCA signal is "00E2 00E2" (approx).

I checked theother device code with the same code (ie, 0143) and it performs the same. If that makes sense to you, does it also make sense why only the 'even' codes work?

Rob.

Rob, that extra "lead-in" time is usually intended to be AGC (automatic gain control). It may be that RCA used to do that and no doesn't and that OFA hasn't modified their RCA algorithm (just guessing). Anyway, it is not likely to be the problem, since it wouldn't distinguish between odd and even.

I notice the modulation wavelength is longer in the Cinema 7 (48 instead of 47) and the pulses are more wavelengths (1d instead of 1c). That product 48*1d instead of 47*1c is the pulse width. If the RCA receiver were really stupidly designed, it might accumulate the descrepency in pulse width across the whole signal. Remember that the low bit is sent last in RCA protocol (unlike most). A cumulative error in pulse width might make it miss the last bit. It's not very likely, but I don't know what else to guess.
