The WWS800 scanner provides advanced data editing functions for data
formatting. Data editing is performed according to user configured editing formats.
Up to three editing formats can be configured.
Data is divided into fields by user specified rules. These fields, together with user
configurable additional fields, constitute the data actually sent to the host computer.
The detailed descriptions and the configuration procedures of the editing format are
described in this section.

To start configuring an editing format, the editing format to be configured must first
be selected by scanning the "Format Selection" in the "Editing Format Parameters"
section of the Reference Guide. Once it is selected, the parameters pertaining to
editing format (applicable condition, total number of fields, field dividing rules,
additional fields, and field transmission sequence parameters) can be configured.
After all the desired parameters are configured, the "End of Format Programming"
label must be scanned to complete the configuration of that editing format.
Note: Before completing the configuration of the editing format, if parameters other
than those pertaining to editing format are read, the editing format under
configuration will be aborted. User must restart the configuration again by selecting
editing format to be configured.

After the editing format to be configured is selected, scan the "Restore Default
Format" label to return the editing format back to default setting. The default
settings of the editing format are listed below.
• Applicable Code Type: All
• Applicable Length: Both max and min length is zero.
• Matching string: Empty
• Matching String Location: 0
• Total number of fields: 1
• Field Setting: Not Configured
• Additional Fields: Empty
• Field Transmission Sequence: F1

Three applicable conditions can be configured to qualify determine the data read by
the scanner can be processed by the particular editing format. Data editing will not
be performed unless all three applicable conditions are met. The configurable
applicable conditions are described below.
• Code Type: This parameter specifies the code type of the data eligible for
data editing. Multiple code types can be specified for this parameter.
• Data Length: This parameter specifies the length (character count) of the
data eligible for data editing. It is specified in the range format. The length
of the data must fall between min and max length limits. If the max length
and the min length configured is both zero, the scanner will not perform this
length qualification.
• Matching String and its Location: User can specify a particular character
string (up to four characters) that must appear in the data that is eligible for
data editing. User can also specify where (character position, starts from
one) this string should appear in the data by configuring the matching string
location. If the location specified is zero, the scanner only checks for the
existence of the matching string in the data. To disable the matching string
qualification, just leave the matching string empty.

Data can be divided into a maximum of 6 fields. The total number of fields
configured must be correctly specified. The fields are numbered from F1 to F6
accordingly, but only F1 to F5 can be configured. The number of configurable
fields is always one less than the total number of fields specified. The extra data
characters beyond the last field configured will be automatically assigned to the
next field. That is, if three fields are configured for the editing format, the data
characters after F3 will be assigned to F4 automatically. This feature is quite useful
when data of variable lengths are processed by editing formats.

Data eligible for editing format is divided into fields according to user specified
rules. The rule for each field can be configured in two ways.
• Field Terminating String: The field dividing rule can be configured by
specifying the field terminating string. The field terminating string
configured can be up to two characters. The scanner will search for the
occurrence of this particular string in the data for the field. The field
terminating string is always included in the field. The user has the option of
discarding this terminating string.
• Field Length: The field dividing rule can be configured by simply
specifying the field length. The scanner will assign the next specified
number of characters into the field.
