5. Data Packet Setting
As mentioned before, in RS232, you need to set the start bit, the data bits, the
check bit (optional) and the stop bit of each frame of data. “Start Bit” has been
specified by the “Polarity Setting”. The setting methods of other parameters
are introduced below:
 Press Data Bits to set the data width of each frame. It can be set to 5, 6, 7,
8 or 9 and the default is 8.
 Press Stop Bit to set the stop bit after each frame of data. It can be set to
1 bit, 1.5 bits or 2 bits.
 Press Even-OddCheck to set the even-odd check mode of the data
transmission. It can be set to None, Odd Check or Even Check.
 Press Packet to enable or disable the packet end. When packet end is
enabled, several data blocks are combined according to the packet end.
 Press PacketEnd to set the packet end during the data transmission and it
can be set to 00 (NULL), 0A (LF), 0D (CR), 20 (SP) or FF.
6. Display-related Setting

7. The Error Expression during Decoding
DS6000 makes full use of the resources such as color and view to express the
results of the protocol decoding effectively and let users find the desired
information quickly.
End Frame Error:
Errors generated when the end frame condition is not met. For setting with the
stop bit as 1.5, if the stop bit is less than 1.5, the data will be filled with red
patches.
