Specifications Manual
1. Abstract
This manual provides specifications for the NLV 2001 fixed-position laser barcode scanner.
2. Overview
The NLV 2001 is a fixed-position laser barcode scanner.
• The scannable width at the minimum scan distance is 44 millimeters and the scan
angle is 44° degrees.
• A short-wavelength red laser improves the visibility of the scan line.
• The NLV 2001 outputs scanned and decoded data via RS-232C, USB, or Wedge
interfaces.
• The NLV 2001 complies with RoHS.
