Accu-Sort Systems
Code set
The specific assignment of data characters to symbol characters.
Communications Protocol
The rules governing exchange of information between devices connected together on the same communications line.
Configuration
The arrangement and interconnection of hardware components within a system, and the hardware (switch and
jumper) and software selections that determine the operating characteristics of the system.
Configuration file
The set of attributes which belongs to and defines the operation of a single physical device.
Continuous code
A bar code symbology where all spaces within the symbol are parts of the characters (Interleaved 2 of 5). There is
no interactive gap in a continuous bar code symbology.
Conveyor Speed
The speed that the conveyor is moving measured in feet per minute. Conveyor speed directly impacts the time that the code is in
front of the scanner; therefore, it affects the number of reads that are possible.
CPI
Characters per inch. See density.
CR (Carriage Return)
An ASCII or EBCDIC control character that moves the cursor or print mechanism to the left margin.
CRT (Cathode-Ray Tube)
Device similar to a television screen for sending, receiving, and displaying serial data. Also known as Dumb Terminal, Display
screen, or Monitor.
CTS (Clear to Send)
The Modem interface signal that indicates to the DTE device to begin transmission.
Current Loop
Method of interconnecting terminals and transmitting signals, whereby a mark (binary 1) is represented by current on the line and
a space (binary 0) is represented by the absence of current.
Decode
The process of translating a bar code into data characters using a specific set of rules for each symbology.
Decoder
As part of a bar code reading system, the electronic package which receives the signals from the scanner, performs
the algorithm to interpret the signals into meaningful data and provides the interface to other devices.
Decoder Logic
The electronic package that receives signals from the scan head, interprets the signals into useful data, and provides the interface
to other devices.
Depth of Field
The distance between the maximum and minimum plane in which a symbol can be read. This range is from the specified optical
throw to the far reading distance.
Density
The number of data characters which can be represented in a linear unit of measure. Bar code density is often
expressed in characters per inch (CPI).
DIP Switches
Switches that are the approximate size of an integrated circuit.
Discrete code
A bar code or symbol where the space between characters, intercharacter gap, are not part of the code as with Code 39. See
continuous code.
