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 of data. 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 Checkout or Even Checkout.
 Press Packet to enable or disable the packet end of data transmmision.
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
Press Format to select the display format of the bus: Hex, Decimal, Binary or
ASCII.
Press Offset and use to adjust the vertical display position of the bus.
Press BusStatus to turn the bus display on or off.
7. Decoding Table
The decoding table displays the decoded data, the corresponding line number,
time and error information on TX and RX data lines in table format. It can be
used to observe relatively longer decoded data to solve the problem that some
data could not be seen clearly on the screen. Note: when the RX channel is
turned off, the information of this data line will not be displayed in the decoding
table.
Press Event Table  Event Table to select “ON” (note that this operation is
only available when BusStatus is set to “ON”) to enter the decoding table
interface as shown in the figure below. If error occurs during the decoding, the
corresponding error information is displayed. If a USB storage device is currently
connected to the instrument, press Export to export the data table to the
external USB storage device in CSV format.
