Function Description - Datalogic PowerScan D8530 Reference Manual

B PROGRAMMING FOR EXPERT USERS
This document is addressed to expert users who are familiar with software
programming languages and want to define a personalized code formatting. The
provided programming language allows creating either simple or complex formatting
expressions by means of the basic functions connected together through the
following operators: (, ), -, +.
The syntax to be used to transmit the expressions to the PowerScan® D8530 is the
following:
$+ELB<n>formatting expression<ETX>$-
where:
−
<n> is a number in the range 1-5 corresponding to the format to be defined;
−
<ETX> is the conventional character used as terminator of the command;
−
the formatting expression uses ASCII characters when containing text strings.
For this reason, the string must be inserted between two quotation marks. The
following example shows the ASCII conversion of the "ABC" string:
$+ELB1 414243 +#DS^C$-.

FUNCTION DESCRIPTION

All the functions and conventions to be used within the formatting expressions are
listed below:
