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.
