Scanner. An electronic device used to scan bar code symbols and produce a digitized pattern that corresponds
to the bars and spaces of the symbol. Its three main components are:
1. Light source (laser or photoelectric cell) - illuminates a bar code.
2. Photodetector - registers the difference in reflected light (more light reflected from spaces).
3. Signal conditioning circuit - transforms optical detector output into a digitized bar pattern.
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
Secure Sockets Layer (SSL). SSL is a commonly-used protocol for managing the security of a message
transmission on the Internet. SSL uses a program layer located between the Internet's Hypertext Transfer
Protocol (HTTP) and Transport Control Protocol (TCP) layers. SSL is included as part of both the Microsoft
and Netscape browsers and most Web server products. Developed by Netscape, SSL also gained the
support of Microsoft and other Internet client/server developers as well and became the de facto standard
until evolving into Transport Layer Security. The “sockets” part of the term refers to the sockets method of
passing data back and forth between a client and a server program in a network or between program layers
in the same computer. SSL uses the public-and-private key encryption system from RSA, which also
includes the use of a digital certificate.
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.
SHIP. Symbol Host Interface Program.
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.
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
