early as 12A without upgrading that software to the latest revision. With this enhancement, an
installer can load a new version of VMMI programming anytime without disrupting existing
programmed databases.
It is important to understand that when installers program older revision software database files with
this current revision VMMI, the newer VMMI will blank and disable any new features that do not
apply to the older revision software. For example, when using 13A revision VMMI to program a
12A software revision database file, installers will not be able to use the controls resident in the IST
Board Programming dialog. However, if the installers translate the database to revision 13A, these
controls are enabled for programming.
The 13A revision of VMMI enables you to do the following:
•
connect to and program systems running 12A software,
•
connect to and program systems running 13A software,
•
create off-line a 12A database for download to systems running 12A software,
•
create off-line a 13A database for download to systems running 13A software,
• translate CCB databases with revisions earlier than 12A to revision 12A for download to
systems running 12A software,
• translate CCB databases with revisions earlier than 13A to revision 13A for download to
systems running 13A software.
To fully support the backwards compatibility enhancement, the software designers have changed
several areas of the VMMI user interface. These areas are discussed in the following paragraphs.
Opening Database Files
When opening a database file that is at a revision earlier than the current VMMI revision, VMMI
will no longer automatically translate that database to the current revision.
When opening a database file with a revision of 12A or later, VMMI opens the database and allows
programming while leaving the database revision unchanged.
When opening a database file with a revision prior to 12A, VMMI informs installers that they must
translate the database a newer revision with the File/Open As operation.
Translating Database Files
Installers may use the VMMI File/Open As operation to translate databases to newer revisions and
to translate DXP databases to the DXP Plus or DXP Plus w/ IMIST Module platforms.
