Glossary
PRINTED CIRCUIT
BOARD A computer board that an electronic circuit has been printed or etched
on.
PRINTER An output device that prints data from the Site Controller.
PRINTOUT A printed copy of the information produced by the Site Controller.
PROGRAM A set of prepared instructions that a computer such as the Site Controller
carries out in sequence to provide a solution to a problem.
PROGRAMMABLE
READ ONLY
MEMORY A type of read-only memory (ROM) chip that can be programmed.
PROM See PROGRAMMABLE READ ONLY MEMORY .
PROMPT The character the Site Controller uses to indicate that it’s waiting for your
response. The prompt for the Site Controller II is the current drive letter
(A, B, C, or D) followed by an asterisk. The prompt for the Site Controller
III is P. Commands that require you to enter additional information
display prompts to tell you what information to enter. The console and
island card reader also display prompts when additional information
must be entered.
PROPRIETARY
CARD A magnetic strip or optical card issued for use with a specific CFN
system. Proprietary cards must conform to the CFN proprietary card
format.
PUMP In CFN System documentation, one hose on a single or dual dispenser
or pump, or one set of hoses on a multi-product dispenser.
RAM See RANDOM ACCESS MEMORY .
RANDOM ACCESS
MEMORY The temporary storage device for programs and data for a computer’s
central processing unit. CFN System devices use battery-backed-up
RAM, so the contents of the memory are preserved even during a power
failure.
READ ONLY
MEMORY Computer memory that stores information permanently and that cannot
be altered by normal operation of the computer.
RECORD A collection of related information treated as a unit. For example, all the
information about a completed transaction makes one transaction
record.
REMOTE A remote command means the Site Controller is accessed through its
remote port by a remote host. Remote verification means transactions
are authorized by a host system.
RETURN KEY The key that on a typewriter would actually return the carriage. On the
Site Controller data terminal it signals the end of a line or the entry of a
command. Also known on some terminals as the ENTER key.
ROM See READ ONLY MEMORY .
RS-232 An industry-standard serial interface used to attach devices such as
modems, printers, to your Site Controller. A type of cable.
RS-422/485 An industry-standard serial interface used to attach reader terminals,
pump control units, and other CFN System devices to the Site Controller.
A type of cable. The 422 is a single device, the 485 a multiple device.
RUN When the Site Controller is running, it is allowing transactions. You can
also run—that is, execute—a program or command file.
SCSI Abbreviation of small computer system interface. Pronounced scuzzy,
SCSI is a parallel interface standard used by Macintosh
® computers,
some PCs, and many UNIX ® systems for attaching peripheral devices to
computers. SCSI interfaces provide for faster data transmission rates
(up to 40 megabytes per second) than standard serial and parallel ports.
In addition, you can attach many devices to a single SCSI port, so that
SCSI is really an I/O bus rather than simply an interface.
