1. Abstract
This manual provides specifications for the OPI 2201 mager Scanner.
2. Overview
The OPI 2201 scanner enables smooth scanning of linier (1D) and 2D symbologies with an
automatic focus function.
The main features of the OPI 2201 are:
Effective use of liquid lens: With an embedded liquid lens in the scanner, the OPI 2201 is
able to read both high resolution and barcodes at large distances.
Skillful laser aiming: The laser pointer makes the scanner easy to aim and consequently
enhances reading performance.
Realization of auto-focus function: Not only is the laser light used for aiming, but also for
distance range so that hi-speed auto-focus is enabled. When the distance range with laser light
is impossible due to environmental conditions, the focus adjustment will be done using the
contrast method.
High-speed, ultra-sensitive mega pixel CMOS image sensor: A customized CMOS image
sensor allows the scanner to achieve a frame rate of 30 fps with 1.3 million pixels. Due to the
information capacity—which is four times more than that of VGA-class sensors—the image
sensor makes it possible to scan images at wide angles and high resolutions.
The world's fastest image processing speed: High-speed ASIC enables a quick response—
equal to that of VGA-class sensors—by processing the vast amount of information transferred
from the mega-pixel CMOS image sensor in a very short time.
Image capture mode: In this mode, an adjustment to ensure sufficient brightness is enabled
by configurations for photometrical area and γ(gamma), in order to capture clearer images
than ever before.
Strain-reducing rubber stabilizer: The scanner features a rubber stabilizer around the handle
to reduce operator strain during long periods of use. Recessing the image scanning section not
only enhances resistance to hand movement, but also scanning performance.
Various interfaces: The OPI 2201 supports RS-232C, Keyboard Wedge, USB (HID), USB
(VCP) interfaces. USB (VCP) enables command communication from the host through the
Virtual Com Port.
Complies with RoHS: The OPI 2201 complies with RoHS (the restriction of the use of certain
hazardous substances in electrical and electronic equipment, 2002/95 EC).

6. Electrical Specifications
6.1. Configuration
The OPI 2201 consists of a focus control section which emits the laser; a liquid lens drive
section; a CMOS sensor; a camera section in the lens; a decode and communication
section that decodes 1D and 2D symbologies data from the scanned image; an interface
section, which outputs the main power supply (3.3v) conversion and the result of
decoding; and a power supply section.
The liquid lens is adjusted by trigonometry. (It determines the distance between the
scanner and a scanning object using the actual distance between laser light and the
center of the object.)
The USB models of the OPI 2201 operate on bus power and those models do not require
adaptors for the power supply. However, the RS-232C and Wedge models of the OPI
2201 operate using the power supply (DC 6.0 V) supplied through a dedicated adaptor.
Since the interface cable of OPI 2201 Wedge model is connected to the host, it is
possible to use the keyboard even if the scanner is not supplied power through the
dedicated AC adapter, though the scanner cannot scan barcodes unless it is receiving
power through the adapter.
Do not suddenly turn off the adaptor power. Doing so could cause the OPI 2201 to
malfunction.
