Datalogic Scanning D8530 User Manual

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: 
$+ELB1S414243T+#DS^C$-. 

 
 

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

FSTR 

Searches for a defined substring by its starting and ending 
string. 

FLSTR 

Searches for a defined substring by its starting string and its 
length. 

SSTR 

Extracts a defined substring from the original string. 

FPOS 

Searches for a position of a defined substring within the 
original string. 

LSTR 

Returns a string length. 

ISTR 

Insert a substring in the original string. 

RSTR 

Substitutes a defined substring contained in the original
