Manual No. 25-NFT1121-01 Series NFT-1121/2135 Mini CCD Fixed Position Scanners Section 3 Positioning the Scanner Getting Optimum Performance Three items greatly impact performance: 1. Distance from the scan window to the bar code 2. Specular Reflection 3. Quality of bar code labels 1) Distance to the Bar Code The operation of the scanner is similar to a camera. If you photograph an object that is out of focus, the resulting picture will be blurry. The same is true with the scanner.
Manual No. 25-NFT1121-01 Series NFT-1121/2135 Mini CCD Fixed Position Scanners Depth-of-Field Just as with a camera, the scanner has a depth-of-field. It can read bar codes that are not precisely at the focal distance - maybe a little closer, or a little farther away. However, if the bar code label is positioned too far from the focal distance, the scanner may not be able to successfully decode it. The depth-of-field varies based on the density of the bar code, i.e., the thickness of the bars.
Manual No. 25-NFT1121-01 Series NFT-1121/2135 Mini CCD Fixed Position Scanners 2) Avoiding Specular Reflection Do not position the scanner at an angle that causes the LED illumination to be reflected directly back into the scanner. This is called specular reflection. Too much reflected light can blind the scanner preventing a good decode. If the bar code label is located on a flat surface, specular reflectivity occurs between 2 to 9 degrees off perpendicular (see diagram).
Manual No. 25-NFT1121-01 Series NFT-1121/2135 Mini CCD Fixed Position Scanners Measuring Scanner Performance Two methods are helpful in determining the optimum position of the scanner. The first method is to program the scanner for Trigger Disable and Continuous Read modes. The scanner will be always on and will continuously read the same bar code.
Manual No. 25-NFT1121-01 Series NFT-1121/2135 Mini CCD Fixed Position Scanners Application Notes: Tips for Achieving High Throughput In some applications your primary objective may be to achieve the highest possible throughput rate. The following list identifies the parameters and scanner settings that can maximize scanning and decode throughput speed. Note, by emphasizing maximum throughput, other areas of performance may be affected. For example, the number of non-reads could increase.
Manual No. 25-NFT1121-01 Series NFT-1121/2135 Mini CCD Fixed Position Scanners 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 Decoded data is transmitted A bar code is scanned but is not decoded (e.g.
Manual No. 25-NFT1121-01 Series NFT-1121/2135 Mini CCD Fixed Position Scanners Section 4 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.

Manual No. 25-NFT1121-01 Series NFT-1121/2135 Mini CCD Fixed Position Scanners Introduction Two different methods can be used to program parameters to configure the scanner: a) Programming via bar codes from a menu page; or b) Programming via computer commands Programming via Bar Codes Use the following steps to program parameters via the bar code menu: 1) Scan the START/END Programming Menu bar code. This instructs the scanner to enter the Programming Mode.
Manual No. 25-NFT1121-01 Series NFT-1121/2135 Mini CCD Fixed Position Scanners Parameters modified by downloading software commands remain in effect only while power is supplied to the scanner. If power is interrupted or terminated, the parameters return to their original settings. However, parameters programmed by downloaded commands can be stored permanently by transmitting a Z2 computer command to the scanner after the commands are sent.

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. The Time-out period is the same whether the scanner is operating in Single, Multiple or Continuous Read mode.
Manual No. 25-NFT1121-01 Series NFT-1121/2135 Mini CCD Fixed Position Scanners 26. 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 decoded the bar code and obtained the same values three times in succession.
