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 CFN 3 logo on the front of the
tower. Refer to
“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. Refer to
“CFN III” .
