Manchester Serial Decode
This section covers decoding Manchester signals. Please read the following for more details:
"Manchester Signal Settings" and "Manchester Serial Decode".
16.12.1 Manchester Signal Settings
Connect the Manchester signal to the oscilloscope, set the mapping relation between channels and
signals, and then set the threshold level of the signal. The process of specifying the source and
threshold is similar to "I2C Signal Settings"
In the Protocol Config menu of decode, the following parameters are available:
A. Touch to specify the baud rate, the range is 500b/s to 5Mb/s
B. Set the Manchester signal's logic type. R:1 indicates that
rising edge is used to encode a bit value of logic 1, and F:1
indicates that falling edge is used to encode a bit value of
logic 1
C. Set the idle level
D. Set the starting edge of the Manchester signal. The range is
1~32
E. Set the minimum idle time/inter-frame gap time of the
Manchester bus in terms of the bit width.
F. Set the display format to Byte or Bit
G. Set the bit order to MSB or LSB
H. Set the sync field size, from 0 to 32
I. Set the header size, from 0 to 32
J. Set the number of words in the data field, from 1 to 255
K. Set the data word size, from 2 to 8
L. Set the trailer size, from 0 to 32
M. Return to the previous menu
