Virtual Wedge Grid
Purpose: Sets the virtual wedge grid. The grid filters the data coming from a 5020. The 5020 data
server supports data filtering, which allows you to selectively send scanned data. You
can also use the virtual wedge grid function in the Software Developer’s Kit (SDK) to
selectively send scanned data to an application. For help, see the SDK online help. The
virtual wedge grid is similar to the “format” argument of the C Runtime Library scanf
function.
Configuration: Use one of these methods:
Configuration
Applications
SNMP Bar Codes
Yes Yes No
In the Configuration or Unit Management application, choose Configure and then Data

Chapter 3, “Configuring the 5020.”

Options: The grid can be from 0 to 31 ASCII characters in this format:
<field><field>…<field>
where <field> is any of the following:
•
Literal characters
Any character that must match the corresponding data character. If you want a
literal % symbol in the <field>, you must precede it by another % symbol. For
example, ABC matches the label ABC and ABC%% matches the label ABC%.
•
%<width><type>
% is a format prefix for a <field>.
<width> is any positive integer or NULL. A NULL width means that the field type
(defined next) applies all the way to the end of the data string. A non-null width
means that the field applies to that many characters of data.
<type> is one of the following:
s Any characters. For example, %4s matches any 4-character string.
d Decimal digit. For example, %4d matches any 4-digit decimal
number.
