4.3.3 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.
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 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.
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 (page
Opening the Data Analyzer Menu
47) 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 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.
Press [B] from the Main menu to view the Block Transfer Statistics screen.
Viewing Block Transfer Statistics
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: To determine the number of blocks transferred each second, mark the numbers displayed at a
specific time. Then some seconds later activate the command again. Subtract the previous
numbers from the current numbers and divide by the quantity of seconds passed between the two
readings.
