MicroHAWK V320-F / V330-F / V420-F / V430-F Barcode Reader User Manual
Match Start Position is useful in defining specific portions of a symbol
for comparison. For example, if a symbol contains a part number, manufacturing
date, and lot code info, but you are only interested in the part number
information, you can set the reader to sort only the part number and
ignore the other characters.
Match Start Position determines the portions of symbols that will be
matched by defining the first character in the symbol (from left to right)
that will be compared with those of the master symbol, when Matchcode
Type is set to Enabled or Sequential.
For example, if Match Start Position is set to 3, the first 2 characters
read in the symbol will be ignored and only the 3rd and subsequent
characters to the right will be compared, up to the number of characters
specified by Match Length.

Example: If Match Length is set to 6 in a 10-character symbol, and
Match Start Position is set to 2, only the 2nd through 7th characters
(from left to right) will be compared.
Defines the length of the character string that will be compared with that
of the master symbol when Match Start Position is set to 1 or greater.
When Match Start Position is set to 0, no comparison will occur.

1 to 3000
Example: With Wild Card Character defined as the default asterisk,
defining CR*34 as the master symbol will result in matches for CR134
and CR234, but not CR2345. Entering URGENT** as your master symbol
will result in matches for URGENT, URGENT1, and URGENT12 but not
for URGENT123. This means any wild cards appended to the master
symbol data will result in matches of symbols in variable lengths up to the
master symbol lengths but not over. However, wild cards in the beginning
or center of a symbol (e.g., UR**NT) do not allow for variable symbol lengths.
Wild Card Character allows a user to define a wild card character as part
of the master symbol.
