Scanning Mode The scanner is energized, programmed and ready to read a
bar code.
Scanning Sequence A method of programming or configuring parameters for a
bar code reading system by scanning bar code menus.
SDK Software Development Kit
Self-Checking Code A symbology that uses a checking algorithm to detect
encoding errors within the characters of a bar code symbol.
Shared Key Shared Key authentication is an algorithm where both the
AP and the MU share an authentication key.
SID System Identification code. An identifier issued by the FCC
for each market. It is also broadcast by the cellular carriers
to allow cellular devices to distinguish between the home
and roaming service.
SMDK Symbol Mobility Developer’s Kit.
Soft Reset See Warm Boot.
Space The lighter element of a bar code formed by the background
between bars.
Specular Reflection The mirror-like direct reflection of light from a surface,
which can cause difficulty decoding a bar code.
Spring Radio Protocol A radio protocol that may be used by the Symbol radio
card. Symbol Radio cards that use the Spring protocol also
have an Net ID.
Start/Stop Character 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.
STEP Symbol Terminal Enabler Program.
Subnet A subset of nodes on a network that are serviced by the
same router. See Router.
Subnet Mask A 32-bit number used to separate the network and host
sections of an IP address. A custom subnet mask subdivides
an IP network into smaller subsections. The mask is a
binary pattern that is matched up with the IP address to turn
part of the host ID address field into a field for subnets.
Default is often 255.255.255.0.
Substrate A foundation material on which a substance or image is
placed.
SVTP Symbol Virtual Terminal Program.
Symbol A scannable unit that encodes data within the conventions
of a certain symbology, usually including start/stop
characters, quiet zones, data characters and check
characters.
Symbol Aspect Ratio The ratio of symbol height to symbol width.
Symbol Height The distance between the outside edges of the quiet zones
of the first row and the last row.
