1. Abstract
This manual provides specifications for the OPI 2002 handheld imager scanner.
2. Overview
The OPI 2002 scanner enables smooth scanning of linear (1D) and 2D barcode symbologies.
The main features of the OPI 2002 are:
•High-speed, ultra-sensitive megapixel CMOS image sensor. The customized CMOS
image sensor allows the scanner to achieve a frame rate of 30 fps. The image sensor
also makes it possible to scan images at wide angles and high resolutions.
•World's fastest image processing speed. High-speed ASIC enables a quick
response—equal to that of VGA-class sensors—by processing a vast amount of
information transferred from the megapixel CMOS image sensor in a very short time.
•Strain-reducing rubber stabilizer. The scanner features a rubber stabilizer around the
handle to reduce operator strain during long periods of use.
•Enhanced floodlighting. Eight to ten LEDs enhance floodlighting, supporting faster
reading and decoding. Scanning performance is also improved by increased resistance
to hand movement.
•Light and compact handheld design. Scanner size has been reduced; weight is a mere
135 grams. Handheld design goes well with other appliances, such as personal
computers, and is suitable for use in shops and offices.
•Various interfaces. The OPI 2002 supports RS-232C, keyboard Wedge and USB
(HID/VCP) interfaces. USB (VCP) enables command communication from the host.
•Complies with RoHS. The OPI 2002 complies with RoHS.

Tested the OPI 2002 with Code 39 and PDF417 test samples (resolution = 0.254 mm).
Scanning may fail in certain area as a result of specular reflection.
Note: α, βand γrespectively represent pitch, skew and tilt. Please see section 7 for how
these values are defined.
Lighting LEDs were kept ON during the test.

6. Electrical Specifications
6.1. Configuration
The OPI 2002 consists of:
•A camera module, which includes the lens and CMOS sensor
•A decode and communication section, which decodes the scanned data and
controls the system
•An interface section, which outputs decoded data
•A power supply section
The USB models of the OPI 2002 operate on bus power and those models do not require
adaptors for the power supply. RS-232C and Wedge models of the OPI 2002 operate on
the power supply (DC 6.0 V) supplied through a dedicated adaptor.
When the interface cable of the OPI 2002 Wedge model is connected to the host, it
cannot scan barcodes, but you can use the keyboard.
