Glossary - 2 MC45 User Guide
bps. See Bits Per Second.
Byte. On an addressable boundary, eight adjacent binary digits (0 and 1) combined in a pattern to represent a specific
character or numeric value. Bits are numbered from the right, 0 through 7, with bit 0 the low-order bit. One byte in
memory is used to store one ASCII character.
C
Codabar. A discrete self-checking code with a character set consisting of digits 0 to 0 and six additional characters ("-", "$",
":", "/", "," and "+").
Code 128. A high density symbology which allows the controller to encode all 128 ASCII characters without adding extra
symbol elements.
Code 3 of 9 (Code 39). A versatile and widely used alphanumeric bar code symbology with a set of 43 character
types,including all uppercase letters, numerals from 0 to 9 and 7 special characters ("-", ".", "/", "+", "%", "$" and space).
The code name is derived from the fact that 3 of 9 elements representing a character are wide, while the remaining 6
are narrow.
Code 93. An industrial symbology compatible with Code 39 but offering a full character ASCII set and a higher coding
density than Code 39.
COM port. Communication port; ports are identified by number, e.g., COM1, COM2.
Cradle. A cradle is used for charging the terminal battery and for communicating with a host computer, and provides a
storage place for the terminal when not in use.
D
Decode. To recognize a bar code symbology (e.g., UPC/EAN) and then analyze the content of the specific bar code
scanned.
Discrete 2 of 5. A binary bar caode symbology representing each character by a group of five bars, two of which are wide.
The location of wide bars in the group determines which character is encoded; spaces are insignificant. Only numberic
characters (0 to 9) and START/STOP characters may be encoded.
E
EAN. European Article Number. This European/International version of the UPC provides its own coding format and
symbology standards. Element dimensions are specified metrically. EAN is used primarily in retail.
EMDK. Enterprise Mobility Developer's Kit.
ESD. Electro-Static Discharge
