    This manual provides the necessary instructions for installing and using the Opticon NFT 2100 Fixed Position Scanner. The manual is organized as follows: Section 1 Introduction and Getting Started Describes the general operation of the NFT 2100 scanner. Also provides a Quick Start- Up Procedure that allows you to begin using the scanner immediately.

  • Page 4: Section 1 Introduction And Getting Started

    Introduction and Getting Started Product Overview The NFT 2100 Fixed Position Scanner is a miniature, 200 scan per second, CCD barcode reader designed to be easily incorporated into host equipment. The small physical size makes the scanner easy to integrate into any hardware design. Durability and reliability are assured.

    It is the distance from the left edge of the view to the right edge. For the NFT 2100, the FOV will be 3.1" at its focal distance of 1.4". Any part of a bar code label that is positioned outside of the FOV will make the label unreadable.
  • Page 12 3) Avoiding Specular Reflection Do not position the scanner at an angle that causes the LED light 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.

  • Page 13: Measuring Scanner Performance

    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. The buzzer sound will be loudest and most continuous at the best reading position.

  • Page 14: Tips For Verifying The Presence Of A Bar Code

    Your Opticon scanner, when operated in the Trigger Enabled mode, can be programmed to transmit an error message indicating whether or not a bar code was present. See Section 33 of Appendix C of this manual for details.

  • Page 15: Section 4 Configuring The Scanner

    Scanner 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.

Note: because of the close proximity of bar codes on the page, it is important to aim carefully to ensure that only the desired bar code is scanned.
