Matchcode Type
Sequential Matching
Match Start Position
Note: Match Start Position must be set to 1 or greater to enable this feature. A 0 setting
will disable this feature.
Match Length
Usage: Useful in tracking product serial numbers that increment or decrement
sequentially.
Definition: With Sequential enabled, Sequential Matching determines if a count is in
ascending (incremental) or descending (decremental) order.
Serial Cmd: < K223, matchcode type, sequential matching ,match start position,match
length,wild card character,sequence on No-Read,sequence on mismatch >
Default: Increment
Options: 0 = Increment 1 = Decrement
Usage: 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.
Definition: 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 .
Function: 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 .
Serial Cmd: < K223, matchcode type,sequential matching, match start position ,
match length,wild card character,sequence on No-Read,sequence on
mismatch >
Default: 0
Options: 0 to 3000
Usage: 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.
Definition: 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.
Serial Cmd: < K223, matchcode type,sequential matching,match start position, match
length ,wild card character,sequence on No-Read,sequence on mismatch >
Default: 1
Options: 1 to 3000
