Wasp WPS100 Product Reference Guide

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 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.

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.

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.

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.

MIL 1 mil = 1 thousandth of an inch.

Misread

(Misdecode)

A condition which occurs when the data output of a reader or interface

controller does not agree with the data encoded within a bar code

symbol.

Nominal The exact (or ideal) intended value for a specified parameter.

Tolerances are specified as positive and negative deviations from this

value.

Nominal Size Standard size for a bar code symbol. Most UPC/EAN codes are used

over a range of magnifications (e.g., from 0.80 to 2.00 of nominal).

Parameter A variable that can have different values assigned to it.
