Multicode Expression
Parameter # F1h, 95h
Use this feature to program a multicode expression for
(grid method). The default is 1, which
indicates any bar code.
To set the multicode expression:
1.
Scan the bar code below.
2.
Scan bar codes from the
Alphanumeric Keyboard on page 11-91
3.
Multicode Expression Syntax: [n] [Element 1]; [Element 2 ]; ... [Element n];
Where
n
is the number of elements in the overall expression.
The multicode expression describes the bar code(s) that the decoder can expect to find in an image. Each element
represents one bar code in the SE4500's field of view. The order of elements in the expression is the order in which
bar code data from each element transmits to the host. Elements are defined using one or more of the following
methods:
By Region
. This type of element limits decoding to a specific area within the SE4500's field of view. Region
coordinates are defined as the top left and bottom right corners of the region, expressed in percentages of the field
of view. These can range from 0% to 100%, or 0x00 to 0x64 in hex, for both horizontal and vertical axes. A region
element is constructed as:
[R] [4] [Top, Left] [Bottom, Right]
Where:
•
[R] is the character R
•
[4] is 0x04, indicating there are four bytes thereafter to describe the region
•
[Top, Left] are two values representing the top left corner of the region
•
[Bottom, Right] are two values representing the bottom right corner of the region
Note that the top of the field of view used for multicode expressions is the topmost part of the field of view when the
SE4500's chassis rests on a horizontal surface.
By Code Type
. An element can specify a specific bar code symbology to find and decode somewhere in the field of
view. A code type element is constructed as:
[C] [2] [Code Type]
Where:
•
[C] is the character C
•
[2] is 0x02, indicating there are two bytes thereafter to describe the code type
