OUTLINE FOR PRODUCT REFERANCE MANUAL
Z-3070 CCD BARCODE SCANNER
Dead Zone
An area within a scanner’s field of view, in which
speculum reflection may prevent a successful decode.
Decode
To recognize a bar code symbology (e.g. UPC/EAN )
and then analyze the content of the specific bar code
scanned.
EAN
European Article Number. This European /
international version of the UPC provides its own
coding format and symbology standards. Element
dimensions are specified metrically. EAN is used
primarily in retail.
Element
Generic term for a bar or space.
Encoded Area
Total linear dimension occupied by all characters of a
code patter, including start/stop characters and data.
Host computer
A computer that serves other terminals in a network,
providing such services as computation, database
access, supervisory programs and network control.
Intercharacter
Gap
The space between adjacent bar code characters in a
discrete code.
Interleaved
Barcode
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 the 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.
LED indicator
A semiconductor diode (LED – Light Emitting Diode)
uses as an indicator, often in digital displays. The
semiconductor uses applied voltage to produce light of
