Section 4
Configuring the Scanner
Since the operation of the V520-LHA7127 scanners are microprocessor controlled, it is possible to modify or
program its operation to match your specific application. Changes in parameter settings can be changed or
programmed in two ways.
1. The first method employs specially designed programming bar codes which instruct the scanner to modify
specific parameters.
2. The scanner can also be programmed by sending software instructions from the host PC to the scanner via
the RS-232C connection.
Programming Menus & Commands
Appendix A contains full instructions on how to configure the scanner as well as a complete listing of the
computer commands and programming bar codes that are available to customize the scanner for your
application.
Default Settings
When you modify or change any parameters, the scanner can be programmed to retain the new parameter in
memory, even if power is interrupted or terminated. If for any reason the scanner is instructed to “return all
parameters to default settings,” it will return to the U1 default settings.
Default settings are indicated by a pointing hand symbol (
%
) throughout the menus to follow
To restore the “out of box” factory settings shown in the following table, use the settings U1, P0, B5, B6 and S7
