SERIAL An interface that transmits information bit-by-bit, rather than in whole
bytes like a parallel interface.
SERIAL PORT A port, or interface, that can be used for serial communication, in which
only1 bit is transmitted at a time. Most serial ports on personal
computers conform to the RS-232C or RS-422 standards. A serial port is
a general-purpose interface that can be used for almost any type of
device, including modems, mice, and printers (although most printers are
connected to a parallel port).
SIGN OFF To exit command-entry mode on the Site Controller. After you sign off,
the Site Controller will not allow you to enter commands until you sign on
again.
SIGN ON To enter command-entry mode. When you are signed on, the Site
Controller will allow you to enter commands. To sign on you must enter a
user ID number (for the Site Controller II and III) and a password.
SITE A complete CFN System installed at a location. Also, the business
location that uses a CFN System, such as a gasoline station or a
convenience store with fuel pumps.
SITE CONTROLLER The PC that controls the CFN system. Site Controller is sometimes
abbreviated according to its version, such as SC I, SC II, and SC III. The
SC III has a CFN3 logo on the front of the tower. See
CFN III and
SYSTEM .
SLIP Short for Serial Line Internet Protocol, an Internet standard for
transmitting Internet Protocol (IP) packets over serial lines (phone lines).
Internet information is packaged into IP packets, a method for enclosing
data into small, transmittable units (wrapped up on one end, unbundled
on the other). A service provider might offer SLIP,
PPP , or both. Your
computer must use connection software (usually provided by the service
provider) that matches the protocol of the server’s connection software.
PPP is a more recent and robust protocol than SLIP.
STRING A set of consecutive alphabetic and/or numeric characters.
SYSTEM An organized collection of hardware and software that works together.
The CFN System is made up of a Site Controller I, II or III and the
devices connected to it. See
CFN III .
SYSTEM-BASED
COMMAND A command that is included within the SC III’s operating system. This
means that if you load the operating system into the SC III’s memory
from a floppy disk, you can subsequently remove the floppy disk
containing the operating system from the floppy disk drive and still be
able to use all system-based commands. In comparison, a disk-based
command requires that the disk containing it be in the disk drive or you
cannot use that command.
SYNTAX ERROR An error in the way you entered a command or its options, if any.
TABLE A collection of data organized for quick reference. The Site Controller II
and III store data for pumps, products, tanks, and so forth in tables.
These are called files on the Site Controller I.
TELECOMMUNICATI
ONS The communication from one computer to another over distances,
usually through a telephone line and modems.
TERMINAL A peripheral device used for input and output, usually including a
keyboard and a screen monitor or printer.
TEXT Words (as opposed to graphics, programming commands, or formulas).
UPLOAD To enter data from your computer into another computer. For example,
you could upload transaction data from a Site Controller to another
computer.
USER A person who makes use of a CFN System.
