No additional software mechanisms are needed to conform
to this limit. Laser operation in this class poses no danger
for unintentional direct human exposure.
See CDPD.
A pattern of bars and spaces which either directly
represents data or indicates a control function, such as a
number, letter, punctuation mark, or communications
control contained in a message.
Those characters available for encoding in a particular bar
code symbology.
A digit used to verify a correct symbol decode. The scanner
inserts the decoded data into an arithmetic formula and
checks that the resulting number matches the encoded
check digit. Check digits are required for UPC but are
optional for other symbologies. Using check digits
decreases the chance of substitution errors when a symbol
is decoded.
A discrete self-checking code with a character set
consisting of digits 0 to 9 and six additional characters: ( -
$ : / , +).
A high density symbology which allows the controller to
encode all 128 ASCII characters without adding extra
symbol elements.
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.
An industrial symbology compatible with Code 39 but
offering a full character ASCII set and a higher coding
density than Code 39.
Number of data characters in a bar code between the start
and stop characters, not including those characters.
A cold boot restarts the mobile computer and erases all
user stored records and entries.
Communication port; ports are identified by number, e.g.,
COM1, COM2.
