Linked UCC/EAN-128 Emulation
Certain MicroPDF417 symbols can be “linked” with a 1-D symbol during transmission as if
they were one symbol. The MicroPDF417 symbol provides supplemental data to the 1-D
symbol. Three scanning options are offered for these symbols:
t
If Decode Linked Symbol is selected, Code 128, ITF-14 and UPC/EAN symbols are
not decoded unless a MicroPDF417 symbol beginning with codeword 906, 907,
912, 914, or 915 is present.
t
If Ignore Linked Symbol is selected, MicroPDF417 symbols beginning with
codeword 906, 907, 912, 914, or 915 are ignored.
t
If Autodiscriminate Linked Symbol is selected, the scanner looks for a MicroPDF417
symbol when scanning a 1-D symbol. If a MicroPDF417 symbol is not detected
within the timeout period, the 1-D symbol data is transmitted.
Note: The Timeout Between Decodes, Different Symbols parameter must be
set to 0 before Ignore Linked Symbol or Autodiscriminate Linked
Symbol can be selected.
When scanning a linked symbol, if the 1-D symbol is scanned first the
scanner issues a low beep indicating that the MicroPDF417 symbol
must still be scanned. Move the laser up until this symbol is scanned.
The scanner issues two high beeps: the first indicates the
MicroPDF417 symbol was decoded, the second indicates the entire
linked symbol was decoded.
If the MicroPDF417 symbol is scanned first, the laser opens to a raster
pattern and automatically scans the
1-D symbol. This decode is indicated by a high-low-high beep; the
first high issues when the MicroPDF417 symbol is decoded, the low
issues when the 1-D symbol is decoded, and the second high indicates
the entire linked symbol has been decoded.
