Configuring the Scanner
Since the operation of the NFT-1125/2135 Series scanner is 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. The first method employs specially designed programming bar codes which
instruct the scanner to modify specific parameters. The second is to program the scanner by sending software
instructions from the host PC to the scanner via the RS232 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 interrupted or terminated. If for any reason, however, the scanner is instructed to
return all parameters to default settings (U4), it will return to the factory default settings shown in the
following table.
