4-14 MS-820 Industrial Bar Code Scanner User’s Manual
4–Read Cycle/Trig-
Multilabel
Definition: Multilabel allows the user to define up to 12 bar code labels that can
be read in a single read cycle.
Usage: Multilabel is commonly used in shipping applications where a shipping
label contains individual bar codes for part number, quantity, etc. This
feature allows one trigger to pick up all the labels. AIAG and UCC/EAN-
128 are two application standards that address this need.
Conditions Allows you to choose the number of different labels that can be read in
a single trigger event. The following conditions apply:
1. All noread messages are posted at the end of the data string.
2. If more than one label is within the scan beam at the same time,
label data may not be displayed in the order of appearance.
3. If Matchcode Type is set to Sequential or if Trigger is set to
Continuous Read 1 Output, Number of Labels will default to 1
(if set to any number greater than 1).
4. The maximum number of characters in any one bar code (other
than PDF417) is 64. For PDF417 it’s 2710.
5. The maximum number of characters in a single scan line is 102
(Code 39).
6. The maximum number of characters for all labels is 788, including
preamble, separators, and LRC.
