Decode Lengths
• The allowable decode lengths are specified by options Length1 and Length2 as follows:
• Variable length: Decode symbols containing any number of characters.
• Set both Length1 and Length2 to 0.
• Range: Decode a symbol with a specific length range (from a to b, including a and b).
• Set Length1 to a and set Length2 to b.
• Two Discrete Lengths: Decode only symbols containing either of two selected lengths.
• Set both Length1 or Length2 to the specific lengths. Length1 must be greater than Length2.
• One Discrete Length: Decode only symbols containing a specific length.
• Set both Length1 and Length2 to the specific length.
UPC EAN Params
Allows the configuration of the parameters that apply to more than one UPC or EAN decoder.
• Convert DataBar To UPC EAN - If this is set it converts DataBar bar codes to UPC/EAN format. For this
setting to work UPC/EAN symbologies must be enabled. A check in the checkbox indicates that the option is
enabled.
• UPC Reduced Quiet Zone - Enables decoding of margin-less UPC bar codes.
• Bookland - Enable Bookland decoding. A check in the checkbox indicates that the option is enabled.
• Bookland Format - If Bookland EAN is enabled, select one of the following formats for Bookland data:
• Format ISBN-10 - The decoder reports Bookland data starting with 978 in traditional 10-digit format with
the special Bookland check digit for backward-compatibility. Data starting with 979 is not considered
Bookland in this mode. (default)
• Format ISBN-13 - The decoder reports Bookland data (starting with either 978 or 979) as EAN-13 in
13-digit format to meet the 2007 ISBN-13 protocol.
• Coupon - Enables Coupon code decoding. Note that in order to successfully decode Coupon codes, all of
the correct decoders must be enabled. A check in the checkbox indicates that the option is enabled.
• Coupon Report Mode - Traditional coupon symbols are composed of two bar code: UPC/EAN and Code
128. A new coupon symbol is composed of a single Data Expanded bar code. The new format offers more
options for purchase values (up to $999.999) and supports complex discount offers as a second purchase
requirement. An interim coupon symbol also exists that contain both types of bar codes: UPC/EAN and
Databar Expanded. This format accommodates both retailers that do not recognize or use the additional
information included in the new coupon symbol, as well as those who can process new coupon symbols.
• Old Coupon Report Mode - Scanning an old coupon symbol reports both UPC and Code 128, scanning
is interim coupon symbol reports UPC, and scanning a new coupon symbol reports nothing (no decode).
• New Coupon Report Mode - Scanning an old coupon symbol reports either UPC or Code 128, and
scanning an interim coupon symbol or a new coupon symbol reports Databar Expanded.
• Both Coupon Report Modes - Scanning an old coupon symbol reports both UPC and Code 128, and
scanning an interim coupon symbol or a new coupon symbol reports Databar Expanded.
• Ean Zero Extended – Enable this parameter to add five leading zeros to decoded EAN-8 symbols to make
them compatible in format to EAN-13 symbols. Disable this to transmit EAN-8 symbols as is. Default –
disabled.
• Linear Decode - This option applies to code types containing two adjacent blocks (e.g., UPC-A, EAN-8,
EAN-13). Enable this parameter to transmit a bar code only when both the left and right blocks are
successfully decoded within one laser scan. Enable this option when bar codes are in proximity to each
other.
