It looks like your bit rate is not in sync with the data, or your encoding may be off (# of bits per frame).

You can measure an average of your fastest pulses and calculate bit rate from that:
Bits/s = 1 / <bit-pulse-width(in seconds)>

For example, if bit pulse width is ~104.167 us:
Bits/s = 1 / 0.000104167 = ~9600

Hi,

Thanks for the input. I exact issue is with the parity setting, by changing to odd parity in the analyzer, this got resolved.
