Checklist for Effects
on Files and
Settings in the
Receiving Terminal

The correct cable connects the download computer serial port (COM1 or COM2)
to the RS-232 serial port (COM1) of the VX 675 terminal.

Download Manager, VeriCentre, or DDL.EXE running on the host computer.

The complete OS version to download is located on the host computer.

Select full or partial download of the OS. In a full OS download, the terminal
restarts automatically and the new OS is processed, replacing the existing OS. In
a partial OS download, the terminal returns to Verix Terminal Manager and the
new OS does not process until you manually initiate a terminal restart from Verix
Terminal Manager.

The correct keyed record variables for the download exist in the CONFIG.SYS files
of Group 1. (OS files must always download into GID1
I: drive). The required
variables can also be written into the CONFIG.SYS file as part of the download
operation.

The following files provided by VeriFone CA for full OS downloads must reside on
the host computer:
• The new OS version or OS update (Q*.out, 1*.out, 2*.out, 3*.out,
4*.out, 5*.out, 6*.out).
• A signature file called VFI.p7s for the OS update. This signature file is
generated by the VeriFone CA using the high-level OS certificates for the
VX 675 platform.
• A file called VFI.PED. This file is an encrypted list of the new OS files.

The required Verix Terminal Manager and file group passwords are available to
make the required Verix Terminal Manager menu selections to prepare the
receiving terminal to receive the application download.

A full OS download replaces the existing OS and erases all application files from
the Group 1
I: drive.

A partial OS download returns control of the terminal to Verix Terminal Manager
and does not erase application files from the Group 1
I: drive.

Protected records in the CONFIG.SYS file(s) of the receiving terminal — keyed
records that begin with * or # — are not erased.

An OS download does not overwrite terminal configuration settings, including the
current date and time, passwords, and modem country code. If required, you can
download new terminal configuration settings together with the OS files.
