Tools
Three software tools are available from VeriFone for performing downloads:
VeriCentre Download Management Module (DMM), VeriCentre, and DDL.EXE
(Direct Download Utility).
These tools perform direct downloads and downloads by telephone from a host
computer to an Omni 37xx terminal:
• VeriCentre DMM: Multi-user environment for software downloads. DMM
supports Windows NT clients and has a sophisticated database to manage up
to 100,000 terminals. The Omni 37xx operating system supports file
decompression for archives created using DMM.
• VeriCentre: PC-based software tool to manage applications and data for
VeriFone. In addition to being a database and communications management
tool, VeriCentre automates application downloads and updates to terminal
records.
• DDL.EXE: Download files and data from a development system or other host
computer directly to an Omni 37xx terminal over a serial cable connection.
DDL.EXE is a 32-bit, Windows 95 program included in the VDTK (Verix
Developer’s Toolkit).

Content
In general, you can download files and data to an Omni 37xx terminal. The types
of 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 Omni 37xx terminal during the
manufacture. If necessary, download newer versions during application
development, when preparing for deployment, or to terminals in the field.
• 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.
NOTE
Because of the large size of some download files, VeriFone recommends only
using download tools provided by VeriFone; these tools provide error checking
mechanisms.
NOTE
No special software tool or utility is required to perform back-to-back application
downloads. Only a serial cable connected between two terminals is required. This
data transfer procedure, invoked from within system mode, is handled by the OS
software and firmware of the sending and receiving Omni 37xx terminals.
