9.Data Editing
The WWS800/850 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.
9.1Select Editing Format
To start configuring an editing format, the editing format to be configured must first be selected. Once it is selected, the parameters pertaining to editing format (applicable condition, total number of field, 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 read 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.
9.2Restore Default Format
After the editing format to be configured is selected, user can read the “Restore Default Format” label to put the editing format back to default setting. The default settings of the editing format are listed below.
•Applicable Code Type: All
•Applicable Length: Max length and min length are zero.
•Matching string: Empty
•Matching String Location: 0
•Total number of field: 1
•Field Setting: Not Configured
•Additional Fields: Empty
•Field Transmission Sequence: F1
9.3Applicable Conditions
Three applicable conditions can be configured to qualify whether 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 max and min 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.
9.4Total Number of Fields
Data can be divided into at most 6 fields. The total number of fields must be correctly specified. The fields are numbered from F1 to F6 accordingly, but only F1 to F5 can be configured. Please note that, the number of fields can be configured 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.
9.5Dividing Data into Fields
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 division can be specified by termination string of the field. 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
