Communication port; ports are identified by number, e.g.,
COM1, COM2.
A bar code or symbol in which all spaces within the symbol
are parts of characters. There are no intercharacter gaps in
a continuous code. The absence of gaps allows for greater
information density.
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.
An area within a scanner's field of view, in which specular
reflection may prevent a successful decode.
To recognize a bar code symbology (e.g., UPC/EAN) and
then analyze the content of the specific bar code scanned.
A decoding scheme that converts pulse widths into data
representation of the letters or numbers encoded within a
bar code symbol.
Decryption is the decoding and unscrambling of received
encrypted data. Also see, Encryption and Key.
The range between minimum and maximum distances at
which a scanner can read a symbol with a certain minimum
element width.
A bar code or symbol in which the spaces between
characters (intercharacter gaps) are not part of the code.
A binary bar code 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 numeric characters
(0 to 9) and START/STOP characters may be encoded.
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.
Generic term for a bar or space.
Total linear dimension occupied by all characters of a code
pattern, including start/stop characters and data.
Electro-Static Discharge
Electronic Serial Number. The unique hardware number
associated with a cellular device, which is transmitted to
the system when the device communicates with the
cellular system.
Ethernet communication port. Allows a wired interface to a
radio network.
Flash memory is nonvolatile, semi-permanent storage that
can be electronically erased in the circuit and
reprogrammed. Series 3000 mobile computers use Flash
memory to store the operating system (ROM-DOS), the
terminal emulators, and the Citrix ICA Client for DOS.
