MVI69-GSC ♦ CompactLogix or MicroLogix Platform
Generic ASCII Serial Communication Module

4.2.3 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.

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 (page 58) 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.

Viewing Block Transfer Statistics

Press [B] from the Main menu to view the Block Transfer Statistics 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.
