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:

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.

(The calculation of pitch and tilt angles is based on the skew angle
formula being β = +15°)

Notes

When a barcode is printed on glossy paper or a card case, it may cause
difficulties in scanning due to the reflection of lighting LEDs. To improve scanning
performance under these circumstances, scan the barcode with a scan angle of
15 degrees or with lighting LEDs turned off. When scanning a barcode with
lighting LEDs turned off, confirm that there is enough ambient lighting in the room
(1000 lx or higher), or scanning performance may decline. Scanning performance
may also decline if room light reflects on the barcode surface.

8. Aiming

8.1. Aiming Patterns

During a scan, the green LED patterns shown below will be visible. These patterns
assist you in aiming the imager; they are superimposed on the illuminated scan field.
The aiming patterns are only a guide. They do not indicate exact scannable width or
distance between a imager and a barcode.

Opticon

NLV 2101

Specifications Manual

Figure 6: Aiming patterns

8.2. Aiming Guidelines

• The focal point is where two central LED light patterns (green and square-shaped)

overlap—where two dots meet.

• To scan a barcode within the aiming range, make sure that two central LED light

patterns overlap, then place the center of the overlapping LED light patterns on
the center of the barcode.

• To scan a barcode wider than a width of the aiming range, aim at the barcode

from further away. Make sure that the barcode is between two LED light patterns
on both the right and left.

a) No Handshaking

The imager attempts the communication regardless of the state of the host
system.

Figure 10: No handshaking

b) BUSY/READY

The imager and the host computer notify each other of their state and
whether they can receive data with BUSY/READY through an RTS line.
They can communicate state to each other through a CTS line when
connected as in the following figure.

Opticon

NLV 2101

Figure 11: Busy/Ready communication

The imager stays ON (is able to receive data) except during certain parts
of the process, such as receiving data (buzzer command execution),
transmitting data, and menu processing. The imager checks the CTS line
before transmitting data. When it is ON, the imager transmits data. When it
is OFF, the imager waits for it to turn ON within a set time. The imager will
abort transmission with an error indication (buzzer) when the CTS line is
not ON within a specified period. The Flow Control time-outs are as
follows, and the default setting is “indefinitely“ (I0).

When the CTS line is turned OFF while sending a TxD signal, the imager
transmits one character and waits. When the RTS signal is turned ON while
transmitting a character, the character will be transmitted.

Note: When using loopback (wire connection) for CTS, RTS line of the imager in this

setting, No handshake is not enabled.

c) MODEM

The imager turns CS line ON before transmitting data. Other processes
are the same as BUSY/READY.

Specifications Manual

d) ACK/NAK

After data has been transmitted, the imager expects to receive one of the
following responses from the host:

• ACK response—Action: The imager completes transmission with the

good-read buzzer and returns to the initial state.

• NAK response—Action: The imager sends the data again and waits for

the response from the host.

• DC1 response—Action: The imager returns to waiting for the trigger, if

it has a trigger (the initial state).

• None response—Action: The imager sounds the error buzzer and

returns to the initial state.

ACK/NAK timeout can be set as follows using the menu or commands.
