The scanner is energized, programmed and ready to read a
bar code.
A method of programming or configuring parameters for a
bar code reading system by scanning bar code menus.
Software Mobility Development Kit
A symbology that uses a checking algorithm to detect
encoding errors within the characters of a bar code symbol.
Shared Key authentication is an algorithm where both the
AP and the MU share an authentication key.
Symbol Host Interface Program.
Symbol Mobility Developer Kit.
See Warm Boot.
The lighter element of a bar code formed by the background
between bars.
Symbol's frequency-hopping, spread spectrum cellular
network.
Symbol's implementation of the Spread Spectrum wireless
network, utilizing direct sequencing.
The mirror-like direct reflection of light from a surface,
which can cause difficulty decoding a bar code.
A technique for uniformly distributing the information
content of a radio signal over a frequency range larger than
normally required for robust transmission of data.
Spreading the signal without adding additional information
adds significant redundancy, which allows the data to be
recovered in the presence of strong interfering signals such
as noise and jamming signals. The primary advantage of
spread spectrum technology is its ability to provide robust
communications in the presence of interfering signals.
A radio protocol that may be used by the Symbol
Spectrum24 radio card. Symbol Radio cards that use the
Spring protocol also have an Net ID.
A pattern of bars and spaces that provides the scanner with
start and stop reading instructions and scanning direction.
The start and stop characters are normally to the left and
right margins of a horizontal code.
