Hz. Hertz; A unit of frequency equal to one cycle per second.
I
IEC. International Electrotechnical Commission. This international agency regulates laser safety by specifying various laser
operation classes based on power output during operation.
IEC (825) Class 1. This is the lowest power IEC laser classification. Conformity is ensured through a software restriction of
120 seconds of laser operation within any 1000 second window and an automatic laser shutdown if the scanner's
oscillating mirror fails.
Intercharacter Gap. The space between two adjacent bar code characters in a discrete code.
Interleaved 2 of 5. A binary bar code symbology representing character pairs in groups of five bars and five interleaved
spaces. Interleaving provides for greater information density. The location of wide elements (bar/spaces) within each
group determines which characters are encoded. This continuous code type uses no intercharacter spaces. Only
numeric (0 to 9) and START/STOP characters may be encoded.
Interleaved Bar Code. A bar code in which characters are paired together, using bars to represent the first character and
the intervening spaces to represent the second.
Input/Output Ports. I/O ports are primarily dedicated to passing information into or out of the terminal’s memory. Series
9000 mobile computers include Serial and USB ports.
I/O Ports. interface The connection between two devices, defined by common physical characteristics, signal
characteristics, and signal meanings. Types of interfaces include RS-232 and PCMCIA.
K
Key. A key is the specific code used by the algorithm to encrypt or decrypt the data. Also see, Encryption and Decrypting.
L
LASER. Light Amplification by Stimulated Emission of Radiation.The laser is an intense light source. Light from a laser is
all the same frequency, unlike the output of an incandescent bulb. Laser light is typically coherent and has a high energy
density.
Laser Diode. A gallium-arsenide semiconductor type of laser connected to a power source to generate a laser beam. This
laser type is a compact source of coherent light.
Laser Scanner. A type of bar code reader that uses a beam of laser light.
LED Indicator. A semiconductor diode (LED - Light Emitting Diode) used as an indicator, often in digital displays. The
semiconductor uses applied voltage to produce light of a certain frequency determined by the semiconductor's particular
chemical composition.
