LS 2106 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 | The laser is an intense light source. Light from a laser is all the same |
Amplification by | frequency, unlike the output of an incandescent bulb. Laser light is |
Stimulated Emission | typically coherent and has a high energy density. |
of Radiation |
|
Laser Diode | A |
| 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 | A condition which occurs when the data output of a reader or |
(Misdecode) | 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 can be |
| 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. |
