This chapter contains information and procedures to allow you to perform the
various types of data transfers required to:
•
Develop applications for the VX 680 terminal.
•
Prepare VX 680 terminals for deployment.
•
Maintain VX 680 terminal installations in the field.
•

In this chapter, information pertaining to file authentication is only discussed in the
context of procedures while performing file downloads. See
further file authentication discussion.
The VX 680 terminal contains ports that allow connection to a network, telephone
line, or other terminals (for back-to-back downloads). See
Data can be transferred from a sending system to a receiving system while
performing downloads. The term download also refers to a terminal receiving
data. The term upload describes the process of a terminal sending data.
Use any of the following two operations to program, deploy, transfer data files
from, and support VX 680 terminals:
•
Host computer downloads: Applications, operating systems or OS updates,
and associated files transfer from a host PC to a VX 680 terminal.
•
Back-to-back downloads: Applications and associated files transfer from one
VX 680 terminal to another VX 680 terminal.
The following three methods are available for file and data downloads through the
VX 680 download and upload procedures:
•
Direct downloads: Files and/or data transfer directly from the sending system
(a host computer) to the receiving system (a VX 680 terminal). A special cable
(VPN 05651-xx) connects the RS-232 serial ports of the two systems.
•
Downloads by telephone (via USB external modem): Files and data
transfer over a telephone line from the sending system (a host computer) to
the receiving system (a VX 680 terminal). The modem of the sending host
computer and the modem of the receiving terminal are connected by a
telephone line. Data transfers into the VX 680 terminal through the designated
communication port.
