Checklist
• The correct cable connects the download computer serial port (COM1 or
COM2) to the Omni 37xx RS232 serial port (COM1) (refer to Cable
Connection for Direct Downloads).
• Verify that the RAM size on the receiving terminal is large enough to receive
files uploaded from the sending terminal. If the RAM on the sending terminal is
512 KB, the RAM on the receiving terminal must be at least 512 KB.
Software Checklist • Download Manager, VeriCentre, or DDL.EXE running on the host computer.
• The complete OS version to download resides on host computer.
• Determine 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 system mode
and the new OS does not process until you manually initiate a terminal restart
from system mode.
• The correct keyed record variables for the download exist in the CONFIG.SYS
files of Group 1. (OS files must always download into GID1 RAM). 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).
• A signature file, called VFI.P7S, for the OS update. This signature file is
generated by VeriFone CA using the high-level OS certificates for the
Omni 37xx platform.
• A file called VFI.PED. This file is an encrypted list of the new OS files.
• One or more digital certificates (*.crt) download with the OS update.
All new OS files, including VFI.P7S, VFI.PED, all certificate files, and any
other files in the download package provided by VeriFone CA, must download
together into Group 1 RAM.
• The required system mode and file group passwords are available to make the
system mode menu selections required to prepare the receiving terminal to
receive the OS download.
• Sufficient memory space exists in the Group 1 RAM to accept the OS
download package including certificates, signature files, and all data files.
