Manual No. 25-ULNFT2100-01; Mar, 2005 Scanner NFT 2100 CCD Fixed Mount Barcode Measuring Scanner Performance A method for properly positioning the unit is to program the scanner for Trigger Disable (S7) and Continuous Read (S2) modes. The scanner will now be always on and will continuously read the same bar code. Since the buzzer sounds each time the bar code is read, the sound of the buzzer can be used like a “Geiger counter”. As the position of the scanner changes the sound of the buzzer will change.
Manual No. 25-ULNFT2100-01; Mar, 2005 Scanner NFT 2100 CCD Fixed Mount Barcode Tips for Verifying the Presence of a Bar Code If the scanner is operated in the “trigger enabled” mode and the trigger is activated, one of three conditions may occur: A bar code is scanned and decoded. A bar code is scanned but is not decoded (e.g.
Manual No. 25-ULNFT2100-01; Mar, 2005 Scanner NFT 2100 CCD Fixed Mount Barcode Section 4 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.

Manual No. 25-ULNFT2100-01; Mar, 2005 Scanner NFT 2100 CCD Fixed Mount Barcode Appendix A Programming the Scanner Two different methods can be used to program parameters to configure the scanner: a. Programming via Computer Commands b. Programming via special Bar Codes from a menu page Most parameters can be programmed using either of these two methods. However, there are certain parameters that are only programmable via the bar code menu. a.
Manual No. 25-ULNFT2100-01; Mar, 2005 Scanner NFT 2100 CCD Fixed Mount Barcode When the scanner is in the Programming Mode, you can change more than one parameter at a time. However, this may become confusing. Until you become proficient at programming you may prefer to change only a few parameters at one time. We recommend that you keep a record of the changes you have made to the scanner. Note, while you are in the programming mode the scanner will not read regular bar codes.

(Each read will reset the scanner’s time out) Scanner will read different bar codes in succession if they are presented to the read window. Scanner may not read the same bar code twice if they are consecutive. (See Sect.

Manual No. 25-ULNFT2100-01; Mar, 2005 Scanner NFT 2100 CCD Fixed Mount Barcode 28. Scanner Timeout (Trigger Enabled Mode only) These commands, which are only applicable in the Trigger Enabled mode, establish the time-out period after the trigger pulse is received. In Single Read Mode, the time out is terminated upon a good read. In Multiple Read and Continuous Read Modes the time out period is restarted after any good read.
Manual No. 25-ULNFT2100-01; Mar, 2005 Scanner NFT 2100 CCD Fixed Mount Barcode 29. Multiple Read Reset Time This option is used in conjunction with the multiple read mode. The selected time sets the period the scanners should be pointed away from a label before that same label can be decoded again. Indefinitely means that the next bar code must always be different during the time the scanner is triggered.
Manual No. 25-ULNFT2100-01; Mar, 2005 Scanner NFT 2100 CCD Fixed Mount Barcode 30. Quiet Zone Options With this option the scanner can decode bar codes that have smaller quiet zone margins than specified for the symbology. Be careful when using this option as its use may increase the possibility of partial and ghost reads. Do not use smaller margin checks than necessary. If possible, replace the bar codes labels with others that have the correct quite zone margins.
Manual No. 25-ULNFT2100-01; Mar, 2005 Scanner NFT 2100 CCD Fixed Mount Barcode 31. Redundant Decoding The Number of Redundant Decodes determines how many times the scanner must decode a bar code and obtain the same value before it will transmit the data. For example, if the redundancy is set at three times, the scanner will not transmit data until it has completed three consecutive, identical “good reads”.
Manual No. 25-ULNFT2100-01; Mar, 2005 Scanner NFT 2100 CCD Fixed Mount Barcode 33. No read error messages. The scanner can be programmed to transmit an error message when no barcode is read. The unit must be in trigger mode, then, the error message will be sent at the end of a trigger time out. 2 types of messages can be sent. The first type will indicate that no label was present or that nothing was in front of the scanner.
