There are two types of Trace windows: Fixed and Rolling. To activate either Trace
window, select the option from the main Tools menu.
FIGURE 3-2: FIXED TRACE WINDOW
FIGURE 3-3: ROLLING TRACE WINDOW
The Trace window displays the CAN BUS traffic in a readable form. This window will
list the ID (Extended is signified with an preceding 'x' or Standard), DLC, DATA Bytes,
the Time stamp and the time difference from the last CAN BUS message on the BUS.
The Rolling Trace window will show the CAN messages sequentially as they appear on
the CAN BUS. The time delta between messages will be based on the last received
message regardless of CAN ID.
The Fixed Trace window will show the CAN messages in a fixed position on the trace
window. The message will still be updated, but the time delta between messages will
be based on the previous message with the same CAN ID.
The Trace window can also be configured with filters to show only certain IDs. This can
be configured in the Trace Filter Setup (refer to Section 3.5 “Future Feature –Trace
Filter Setup Feature”).
