Using the Trace Window to Display System Messages
The Trace Window displays messages that show how the internal processes of the unit are
performing. Because of the number of complex problems it can diagnose, as more product features
are added or enhanced, the Trace Window may contain much more information than you require.
The messages displayed by the system vary based on software revisions.
You can access the Trace Window from any menu of the built-in interface by typing TW. To exit
the window, press the space bar.
To assist in problem diagnosis, you may find it helpful to save the output of the Trace Window for
later review. You should save the output in a file on an attached terminal.
The Trace Window messages are added to the end of a queue that is downloaded whenever the
Trace Window is accessed. Appending the messages is not allowed to interfere with normal data
transfer; therefore, some messages might not be displayed. By checking the sequence of the
messages, you can verify that all messages are displayed.
The following list describes the messages displayed on the screen:
• The record numbers are displayed in the first column and are shown in sequential order. If the
numbers are missing, the missing records have been lost because the unit was too busy.
• The second column shows the time stamp, formatted in milliseconds.
• The process that is displaying the message is shown in the third column.
• The diagnostic message is displayed in the last column.
