Configuring the Scanner
Since the operation of the NFT 2100 scanners are microprocessor controlled, it is possible to modify or
program its operation to match your specific application. Changes in parameter settings can be
accomplished two ways.
1. The scanner can be programmed by sending software commands from the host PC to the scanner via
the RS232 connection. Most commands will be immediately active, but are not stored into non-
volatile memory until the store command, Z2, is sent. A few commands, such as changing the
communication parameters will not be active until they are stored via the Z2 command.
2. The second method employs specially designed programming bar codes referred to as menu
commands. Scanning these bar codes instructs the scanner to modify specific parameters. These
commands are stored into non-volatile memory as soon as the menu command mode is exited.
Once stored in non-volatile memory, these settings will remain even after powering the unit OFF and
ON.
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 non-volatile memory, even if power is interrupted or terminated. If for any reason the
scanner is instructed to return all parameters to default settings (U2), it will return to the default settings
shown in the following table.
Default settings are indicated by a pointing hand symbol (
%
) throughout the bar codes menus.
