    Hi Everybody,
    I am working on RMAP protocol.I have a decoder which can decode RMAP
    and MIT protocol.
    This decoder works on RMAP protocol when the IR receiver is
    R3302,IR_REC_V_56KHz_TSOP2256VI1(not sure who is the manufacturer).
    The decoder also works on MIT protocol,when the IR receiver is
    TSOP1133(dont know who is the manufacturer).

    Observation:
    (1)Since the decoder works fine for both the protocols at different
    receivers, so I am sure that the decoder is working fine(else it
    wouldnt have worked at all).
    I want to make the decoder work for RMAP protocol also, when the
    receiver is TSOP1133(the second case)...in this scenario, it's now
    working only for MIT.

    I want to know:
    (a)Should the IR receiver work for all the protocols? If not why and
    what are the factors that prevent it from working.
    My Guess: If the carrier frequencies for the protocols do not match,
    maybe the IR receiver wont be able to decode it. Is this true? where
    can I find more information about it?

    (b)What is the carrier freq's for RMAP and MIT protocol?
    My confusion: Do the carrier freq depend on the protocol or the remote
    control itself?

    If anybody is having domain knowledge on this, pls pls respond soon.


    Thanks,
    Sudip
