I did a little digging and found that these are all the MCE (RC6-6-32 dev.sub 229.128 no toggle bit) codes in the RCA: AUD 1785, CBL 1272, 2178, TV 1265, 1525, 1863 and DVD 1972, 2083. I think 1972 is the code you want. I'll test them later and update this post with the results. What IR receiver are you using? Some respond to slightly different codes (there are 8 possibilities). If you can tell me exactly what profile you use in your harmony, I can analyze the signals and find an exact match in the RCA.
There is no difference in those 2 models except the cardboard in the package has a red background in the "R" model. The One-for-all OARP05S is also identical except it's silver instead of black.
UDATE: Turns out my Adesso MCE dongle doesn't use standard MCE (uses CBL 2298 which is OrtekMCE protocol), so I can't test it. But I can still look for a code that matches your harmony whenever you can post that info.
