Upc Ean Params - Motorola MC40 User Manual

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 either Length1 or Length2 to the specific lengths.
•
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.
•
Security Level - The scanner offers four levels of decode security for UPC/EAN bar codes. Select higher
security levels for lower quality bar codes. There is an inverse relationship between security and decode
speed, so be sure to choose only that level of security necessary for the application.
•
Level 0 - This default setting allows the scanner to operate fastest, while providing sufficient security
in decoding "in-spec" UPC/EAN bar codes (default).
•
Level 1 - As bar code quality levels diminish, certain characters become prone to misdecodes before
others (i.e., 1, 2, 7, 8). If the scanner is misdecoding poorly printed bar codes, and the misdecodes
are limited to these characters, select this security level.
•
Level 2 - If the scanner is misdecoding poorly printed bar codes, and the misdecodes are not limited
to characters 1, 2, 7, and 8, select this security level.
•
Level 3 - If the scanner is still misdecoding, select this security level. Be advised, selecting this option
is an extreme measure against misdecoding severely out of spec bar codes. Selecting this level of
security can significantly impair the decoding ability of the scanner. If this level of security is
necessary, try to improve the quality of the bar codes.
•
Supplemental2 - Enables or disables this option. A check in the checkbox indicates that the option is
enabled.
•
Supplemental5 - Enables or disables this option. A check in the checkbox indicates that the option is
enabled.
•
Supplemental Mode
•
No Supplementals - the scanner is presented with a UPC/EAN plus supplemental symbol, the
scanner decodes UPC/EAN and ignores the supplemental characters (default).
•
Supplemental Always - the scanner only decodes UPC/EAN symbols with supplemental characters,
and ignores symbols without supplementals.
•
Supplements Auto - the scanner decodes UPC/EAN symbols with supplemental characters
immediately. If the symbol does not have a supplemental, the scanner must decode the bar code the
number of times set via UPC/EAN Supplemental Redundancy before transmitting its data to confirm
that there is no supplemental.
•
Supplemental Smart - Enables smart supplementals. In this mode the decoder returns the decoded
value of the main block right away if it does not belong to one of the following supplemental types:
378, 379, 977, 978, 979, 414, 419, 434 or 439. If the bar code starts with one of the prefixes it
