Specifications Manual
1. Abstract
This manual provides specifications for the NLV 2101 fixed-position 2D barcode imager
(hereafter referred to as “imager”).
2. Overview
The NLV 2101 includes the following features:
• A 1.3 million-pixel (SXGA) CMOS area image sensor, and a compact camera
module with wide-angle lens that enables scanning of wider symbologies at higher
resolution
• Three different models of NVL 2101 (Type-L, Type-I and Type-S) are available
where the position of the optical window differs for each type. The default model
type is the Type-L; the Type-I and Type-S are available for large purchase orders.
• Wide-angle lens optics that make it possible to scan wider symbologies at closer
distances
• A small, high-performance, power-saving decoder that processes data faster and
provides smoother scanning of both linear (1D) and 2D symbologies
• The ability to change symbology settings, scanning settings, and communication
settings by sending commands
Supported symbologies:

Command transmissions (from the host to the imager), decoded data transmissions, and
captured image transmissions (from the imager to the host) are done via serial
communication (unless you are using the USB-HID model of the NLV 2101).

There are three versions of the NLV 2101. Location of the optical window differs,
depending on the version.
The NLV 2101 complies with the Restriction of Hazardous Substances (RoHS).

Decoding performance is guaranteed when the range of illumination on a barcode
surface is between zero and the following values:
Incandescent light to 10,000 lx
Fluorescent light to 10,000 lx
Sunlight to 100,000 lx
Conditions
Barcode Sample: PDF417 with 0.254 mm resolution
Distance: 107 mm from the plastic mask of the camera module
Angle: α = 0° β = 15° γ = 0°
Curvature: R = ∞

Opticon
NLV 2101
Scanning performance is guaranteed as long as direct light or a reflection from a light
source does not impact the light detection range of the NLV 2101.
Note: α, β and γ respectively represent pitch, skew and tilt. Please see section 6 for
how these values are defined.

5. Electrical Specifications
5.1. Framework and Structure
This product consists of a camera module, a decoder, communication controls, an
interface, and a power supply. The camera module consists of a CMOS area image
sensor and lens. The decoder decodes the scanned 1D and 2D codes. The interface
transfers data between this product and the host system.
• The NLV 2101 with RS-232C interface requires the supplied AC adaptor.
• The NLV 2101 with USB interface uses bus power. It does not require an AC
adaptor.
