VX 675 R
EFERENCE GUIDE 101
A complete OS is downloaded to each VX 675 terminal during the
manufacture. If necessary, download newer versions during application
development, or when preparing for deployment to on-site terminals.
Applications and related files: An application is a computer program
consisting of one or more executables, including compiled and linked object
files (*.out), and one or more function libraries (*.lib). Most applications
also include font files (*.vft, *.fon), data files (*.dat), and other related
file types.
VX 675 applications can be developed by VeriFone, customers, or third
parties on customer request. One or more applications must be downloaded
to the VX 675 terminal before it can be deployed at a customer site and used
to process transactions.
Files related to file authentication: The logical component of the VeriShield
security architecture in the VX 675 terminal is file authentication. For an
executable to run on a VX 675 terminal, it must be authenticated by the
VeriShield file authentication module.
Two special types of files are required for the file authentication process:
digital certificates (*.crt) and signature files (*.p7s). These file types must
be downloaded to the terminal together with the application files to
authenticate.
Terminal configuration settings: Files or records that contain various types
of data can also be downloaded to a VX 675 terminal, including CONFIG.SYS
variables, passwords for accessing protected Verix Terminal Manager
functions, the current date and time, and the modem country code setting
(refer to Chapter 4).
Full and Partial
Downloads
When preparing to initiate a download procedure, choose either a full or partial
download and the COM 1 port, through the Verix Terminal Manager menu options
(refer to Chapter 4). Depending on the type of files you are downloading and the
download method you are using, there are some restrictions on whether a full or
partial download is permitted. Full download means all files in group 1-14 will be
deleted. The common group, 15, is not affected. While partial download means no
files currently on the system will be deleted.
NOTE
For details on file authentication, see Chapter 5.
