I am trying to read information from a product, but I am not sure what the baud rate is.· I have a scope and it looks like each pulse width is 15 micro seconds.· Can anyone tell me what the buade rate is.

    1/15microseconds is closest to 57600 baud rate.

    Dave A,

    If the bit width is actually 15us then to find the baud you just take the inverse of this which would be 66666 baud. 57600 baud as mojorizing suggests sounds a bit off as it would have a bit width of 17.36us.
