Worth Data TriCoder t53 User Manual page 101

to make sure the correct type of data is entered. For example, to make
sure the TriCoder only accepts data for this prompt that starts with
1A1, put 1A1 in the Data ID field:
Data Identifiers can be up to 3 characters long and can be position
specific. To only accept data where the second character is "S", put S
in the second character position in the Data ID field:
In this example, the data in positions 1 and 3 can be anything; put
position 2 must be an "S".
2. UPC/EAN Check digit verification for keyed-in data
The second function of the Data ID field is to have the TriCoder verify
the check digit on an UPC or EAN bar code when the data has be
entered on the TriCoder keypad (not scanned). This scenario happens
often when bar codes are damaged or missing and the data has to be
entered by hand. To avoid errors when the data is keyed in, the
TriCoder will calculate a check digit for the data and compare it to the
check digit that was keyed in. If the two digits do not match, the
TriCoder generates the following error message:
To use this feature, enter the following characters at the DATA ID prompt:
U10 - Use this to verify UPC 12 or 8 digit entries
E10 - Use this to verify EAN 13 or 8 digit entries
B10 - Use this to check for both UPC and EAN 13, 12 or 8 digit entries.
UPC/EAN 2 and 5 digit supplements are not supported.
3. Specifying Tables and Pick Lists
The TriCoder can access downloaded tables and pick lists during data
collection. Tables are lists of data that can be either validated (compares
the entered data to the table data) or maintained (finds the entered data in
the table and allows editing of associated data). Pick Lists serve as
instruction to the user in order filling and warehousing applications. The
TriCoder has room for up to 3 tables in memory at a time.
Table validation uses data records that consist of a single field. The user
enters a piece of data into the TriCoder and the TriCoder checks the table
to see if there is matching data. If so, the TriCoder writes the data to the
