RAM
Random-access memory. The type of
memory in which storage locations are addressable
and can therefore be accessed in any order. In the
VX 680 terminal, the mDRAM is used to run
applications.
Application files and data are stored in the non-
volatile flash memory system. By default, files
downloaded to the terminal are stored in the I: drive
of the target file group(s). See
Remote host computer
connected to a VX 680 modem dongle over a dial-up
telephone line to download files or data, or to
process transactions. The opposite of remote is
local.
RS232
Also RS-232C. A widely used standard
interface that covers the electrical connection
between data communication equipment, such as a
modem, and data terminal equipment, such as a
microcomputer or computer terminal. The RS232
interface standard was developed by the EIA
(Electronic Industries Association) and is essentially
equivalent to the CCITT's V.24 interface.
Scroll
To move all or part of the information
displayed on a screen up or down, left or right, to
allow new information to appear. For the VX 680,
text that does not fit entirely within the display area
can be scrolled to the left or right using the pound (#)
and asterisk (*) keys.
Search key
Also called key. In the VX 680, a short
character string used by an application to identify a
keyed file record stored in CONFIG.SYS file(s). For
example, *ZA or *OT. A keyed file record consist of
two parts: a search key to identify the record, and the
variable data stored in the record. See also
file record and CONFIG.SYS
Serial port
A connection point through which
digital information is transferred one digital bit at a
time. Same as serial interface. The VX 680 terminal
has one serial port, available at the multiport
connector. The main serial port on a download
computer is usually assigned the terminal ID, COM1.

file.
Signature file
A digital file with the filename
extension *.p7s generated in an industry-standard
format by the file signing tool, FILESIGN.EXE. The
output of the file signing tool is a signature file in an
industry-standard format.
mDRAM
See RAM.
Subroutine
A software routine that can be part of
another routine. When a main routine calls a
subroutine, program control is transferred to the
subroutine. When the subroutine is completed,
control reverts to the instruction in the main routine
immediately following the subroutine call.
Swipe
The action of sliding a magnetic stripe card
through a terminal card reader. The VX 680 card
reader has a bi-directional swipe direction. The user
must hold the card so that the magnetic stripe is
faces in and towards the keyboard.
Verix Terminal Manager
Terminal Manager temporarily disables normal
mode operations, allowing you to perform local
functions such as downloads, diagnostics, and other
operations that cannot be performed while the
application program is running.
At startup, the terminal displays a copyright notice
screen that shows the version of VX 680 system
firmware stored in terminal memory, the date it was
loaded into the terminal, and the copyright notice.
This screen appears for three seconds. To enter
Verix Terminal Manager, simultaneously press the
ENTER and 7keys during this three-second period.
Pressing any other key(s) during that period resets
the copyright notice screen to display an additional
three seconds.

Verix Terminal Manager password
set of characters entered by the user to access the
Verix Terminal Manager local functions of the
terminal. A default password is supplied with each
terminal. For the VX 680 terminal, the default system
password set at manufacture is: 166831.
To prevent unauthorized access, change the default
password upon terminal deployment. Store the new
password in a safe place, as it is impossible to
restore the terminal default password without
sending the unit to Verifone for service.
