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.

Definition: With Sequential enabled, Sequential Matching determines if a count

is in ascending (incremental) or descending (decremental) order.

Usage: Useful in tracking product serial numbers that increment or decrement

sequentially.

Serial Cmd: <Knmatchcode type,sequential matching,match start position,

match length,wild card character,sequence on noread,sequence on

mismatch>

Default: Increment

Options: 0 = Increment

1 = Decrement

Definition: Match Start Position determines the portions of labels that will be

matched by defining the first character in the label (from left to right)

that will be compared with those of the master label, 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 charac-

ters specified by Match Length.

Usage: Match Start Position is useful in defining specific portions of a symbol

for comparisons. For example, if a symbol contains a part number, manu-

facturing date, and lot code info but the user is only interested in the part

number information. With Match Start Position the scanner can be set

to only sort on the part number and ignore the rest of the characters.

Serial Cmd: <Knmatchcode type,sequential matching,match start position,

match length,wild card character,sequence on noread,sequence on

mismatch>

Default: 0

Options: 0 to 50
