Indicator/
Missing Ack
If there is an error/missing acknowledge in
decoding the serial data, a red error indicator will
be shown.
Bus Indicator
The Bus indicator shows the bus position. The
active bus is shown with a solid color. The Variable
knob can be used to horizontally position the Bus
indicator when it is active.

3-6-2. Serial Bus
The Serial Bus includes support for 5 common serial interfaces, SPI,
UART, I
2
C, CAN and LIN. Each interface is fully configurable to
accommodate variations in the basic protocols.
Each input can be displayed as binary, hexadecimal or ASCII. An
event table can also be created to aid in debugging.
3-6-2-1. Serial Bus Overview
UART
Universal Asynchronous Receiver Transmitter. The
UART bus is able to accommodate a wide range of
various common UART serial communications.
The UART serial bus software is suitable for a
number of RS-232 protocol variants.
