DDL.EXE: Downloads files and data from a development system or another
host computer, directly to a VX 680 terminal over a serial cable connection.
DDL.EXE is a Windows program included in the Verix eVo DTK (Verix eVo
Developer's Toolkit).
No special software tool or utility is required to perform back-to-back application
NOTE
downloads. Only a serial cable connected between two terminals is required.
This data transfer procedure, invoked from within Verix Terminal Manager, is
handled by the OS software and firmware of the sending and receiving VX 680
terminals.
Download In general, you can download files and data to a VX 680 terminal. The types of
Content
files and data can be grouped into the following functional categories:
•
Operating system files: A set of related programs and data files provided by
Verifone to control the terminal's basic processes and functions. Files that
belong to the OS are stored in a reserved area of the terminal memory.
A complete OS is downloaded to each VX 680 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 680 applications can be developed by Verifone, customers, or third parties
on customer request. One or more applications must be downloaded to the
VX 680 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 680 terminal is file authentication. For an
executable to run on a VX 680 terminal, it must be authenticated by the
VeriShield file authentication module.
NOTE
For details on file authentication, see
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 680 terminal, including CONFIG.SYS
variables, passwords for accessing protected Verix Terminal Manager
File Authentication.
