Full and Partial Downloads
VX 675 R
EFERENCE GUIDE 103
Here are a few more points on the topic of full and partial downloads:
The most common download procedure is a full (complete) application
download.
Partial application downloads are useful when developing and testing new
applications, but are seldom performed by those who deploy terminals on-site.
Full OS downloads are usually performed by VeriFone at the factory and, on
occasion, by those who deploy terminals on-site to upgrade older terminals to
a newer OS version.
Partial OS downloads are performed mainly by VeriFone for development
purposes and are rarely performed in the field.
Full operating
system
download
An entire OS version transfers from a host PC
to the VX 675
terminal.
Files related to file authentication and terminal
configuration settings can be included in a full
OS download. During this process, memory is
cleared.
Following a full OS download, the terminal
restarts and the file authentication module is
invoked. If the OS files are authenticated, the
new OS updates (replaces) the existing OS.
Application files stored in the memory area
where the OS downloads (Group 1) are
erased.
Direct downloads
Note: Full back-
to-back OS
downloads
are not
supported.
Partial
operating
system
download
Either an entire or a partial OS version
transfers from a host PC to the
VX 675 terminal.
Files related to file authentication and terminal
configuration settings can be included in a
partial OS download.
Following a partial OS download, the terminal
does not restart and returns control to Verix
Terminal Manager or the issuing application.
The file authentication module is not invoked,
and the new OS is not processed until you
manually restart the terminal from within Verix
Terminal Manager. If the new OS is
authenticated, it then updates (replaces) the
existing OS.
Application files stored in the memory area
where the OS downloads into (Group 1) are
retained.
Direct downloads
Note: Partial
back-to-
back
operating
system
downloads
are not
supported.
