4.1.5 Main Menu
When you first connect to the module from your computer, your terminal screen
will be blank. To activate the main menu, press the [?] key on your computer's
keyboard. If the module is connected properly, the following menu will appear on
your terminal screen:
Caution: Some of the commands available to you from this menu are designed for advanced
debugging and system testing only, and can cause the module to stop communicating with the
processor or with other devices, resulting in potential data loss or other failures. Only use these
commands if you are specifically directed to do so by ProSoft Technology, Inc. Technical Support
staff. Some of these command keys are not listed on the menu, but are active nevertheless. Please
be careful when pressing keys so that you do not accidentally execute an unwanted command.
Opening the Data Analyzer Menu
Press [A] to open the Data Analyzer Menu. Use this command to view all bytes
of data transferred on each port. Both the transmitted and received data bytes
are displayed. Refer to Data Analyzer for more information about this menu.
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 be sure to press
[M] to return to the main menu and disable the data analyzer. This action will allow the module to
resume its normal operating mode.
Viewing Backplane Diagnostic Information
Press [B] from the Configuration/Debug Menu to view the Backplane Diagnostic
Information screen.
Use this command to display the configuration and statistics of the backplane
data transfer operations between the module and the processor. The information
on this screen can help determine if there are communication problems between
the processor and the module.
Tip: Repeat this command at one-second intervals to determine the number of blocks transferred
each second.
