Configuration: Extended Match Table and Counters

Publication 2755-833

Status of Counter Set

Field Type Options

Select

Enabled
Disabled

This parameter activates or deactivates the counters within the
particular set of extended match code values currently displayed. The
default value is Enabled, which means that any extended match code
table entry in the currently displayed set to which a match pattern has
been assigned will be enabled. Selecting Disabled turns off all
entries in the currently displayed set. Keep in mind that this
parameter affects only the currently displayed set.

Use the Screen Status parameter described above to move among
sets within the table. Note that when moving from one screen to
another the “Set” identifier changes to reflect the number of the set
currently displayed.

The ability to turn individual sets of extended match code table
entries on and off at will provides a potentially useful additional
level of process control and flexibility.

Mode

Field Type Options

Select

A = Autoload
M = Match Entry
D = Disabled
L = Lot

The Mode parameter controls the operational status of individual
entries in the extended match code table. The default setting is
Disabled. Other choices include:

Autoload, which configures the specified extended match code
table entry to match the bar code data from the first valid
package(s) into the extended match code table

Once a pattern is entered, the Mode parameter changes to Match
Entry
.

If the bar code data contains the ”%” character, the decoder
displays %% in the match code table, but records a single % in
the data. Use the ”%” character to enter any non-printable
character. For example, %M represents CTRL-M, or carriage
return. See Appendix I.

Match Entry, which activates the specified output when bar code
data matches the string in that row

The duration of Extended Match Code Table outputs are established in the Primary Match Code Table

below.
