Upgrading the DXP Plus Software
The DXP Plus digital communications system includes system software when it ships from the factory.
At initial system installation, you do not need to load the system software to make the system
operational. Should you need to later reload the system software (for software upgrade purposes for
example), you can do so using the supplied system software disk. Use Windows File Manager or
MS–DOS commands to save the disk's information from your computer's floppy drive to its hard drive.
Having the software on your computer's hard drive allows the data to load into the system's memory
much quicker than it would from the computer's floppy disk drive.
To load the system software information, your PC must be connected to the communications system.
The system does not automatically save the existing database during a software upgrade. If you
need to preserve the existing database, you must archive it before you upgrade the software. After
you upgrade the software, you can restore the existing database to the system.
1. Archive the existing database.
a. From the Switch pull-down menu, select the Connect To... menu item, connect VMMI to the system,
and return to the Switch pull-down menu.
b. From the Switch pull-down menu, select the Archive Database menu item.
c. Choose a memory storage location for the archive operation to use and OK your choice. Since the
database can be quite large, you should choose a location on your computer's hard drive to ensure that
you have enough memory to store the database.
d. The system automatically archives its database.
2. From the Switch pull-down menu, select the Connect To... menu item, connect VMMI to the system, and
return to the Switch pull-down menu.
3. From the Switch pull-down menu, select the System Software Upgrade menu item.
4. The system automatically takes itself out of service.
5. Choose the location where the new software data resides (select disk drive, directory, and file), and OK your
choice. The system loads the software data, resets itself, and places itself back in service.
6. Restore the existing database (if desired).
a. From the Switch pull-down menu, select the Connect To... menu item, connect VMMI to the system,
and return to the Switch pull-down menu.
b. From the Switch pull-down menu, select the Restore Database menu item.
c. Choose the memory storage location that contains an archived database and OK your choice. The system
automatically restores its database.
