6.4.4 Data Analyzer
The data analyzer mode allows you to view all bytes of data transferred on each
port. Both the transmitted and received data bytes are displayed. Use of this
feature is limited without a thorough understanding of the protocol.
Note: The Port selection commands on the Data Analyzer menu differs very slightly in different
modules, but the functionality is basically the same. Use the illustration above as a general guide
only. Refer to the actual data analyzer menu on your module for the specific port commands to
use.
Important: When in analyzer mode, program execution will slow down. Only use this tool during a
troubleshooting session. Before disconnecting from the Config/Debug port, please press [S] to stop
the data analyzer, and then press [M] to return to the main menu. This action will allow the module
to resume its normal high speed operating mode.

Analyzing Data for the second application port
Press [2] to display I/O data for the second application port in the Data Analyzer.
Displaying Timing Marks in the Data Analyzer
You can display timing marks for a variety of intervals in the data analyzer
screen. These timing marks can help you determine communication-timing
characteristics.
