1. Abstract
This manual provides specifications for the OPI-3601 handheld 2D imager scanner.
2. Overview
The OPI-3601 is a handheld 2D imager scanner that enables high speed scanning of standard linear
(1D) and 2D symbologies. Main features of the OPI-3601 are as follows:
・High-speed scanning
Extremely high speed performance ensures stress free scanning and fast response without being
affected by hand movement and light conditions.
・Auto trigger, moving object scanning
With the use of a dedicated stand, the scanner is automatically triggered and a moving target can
be detected automatically and scanned instantaneously.
・Editing function
A new function “Data Editing Program” captures up to 16 codes on multiple images simultaneously
in one go. Output editing process, such as GS1 format, also can be set easily.
・World's most compact 2D scanner in its class
The OPI-3601 offers ultra-compact size and easy operation.
・LED aiming
A sharp single line of green LED makes it easy to aim the scanner while providing safety and long-
life.
・Antimicrobial coating
Special antimicrobial treatment is applied to the chassis, and alcohol can be used to clean the
scanner (except for the scanning window and the logo panel).
・Various interfaces
Four types of interfaces, RS-232C, Keyboard Wedge PS/2, USB-HID, and USB-COM, are
supported.
・RoHS compliance
The OPI-3601 is a RoHS compliant product, which is declared by Optoelectronics Co., Ltd.
* Refer to “OPI-3601 User’s Manual” for supported codes and commands.

A sound from a built-in buzzer comes out through these holes. When they
are covered, the buzzer sound may not be able to be heard. The sound
varies depending on the status. Buzzer settings can be configured in
various ways: enable or disable buzzer as well as change the loudness and

The OPI-3601 comprises ‘Camera Module Section’ with CMOS sensor, ‘Decoder Section’ for decoding
1D / 2D code data from a scanned image, ‘Communication Control Section’ to communicate with a host
and ‘Power Supply Section’ for the main power supply conversion.
The USB model is bus powered and no adapter is needed. The RS-232C and Wedge PS/2 models
need a dedicated adapter for DC 6.0 V power. Make sure not to insert and remove the power adapter
when PC is on. It may cause the PC to malfunction.

6.2. Aiming Pattern
The aiming is used for the following purpose:
1. Fill light to recognize the appropriate reading range.
2. Fill light when auto trigger is used.
The aiming specifications are as follows:
- An optical axis of imaging field of view and the center of horizontal aiming width coincide at a
distance of L=85±20 mm from the front edge of the scanner.
- The horizontal aiming width to the horizontal width of imaging filed of view at a distance of L=85
is 80%±10%.

7.8. Auto Trigger
A dedicated stand contains a magnet and when the OPI-3601 is placed into this stand, it can
detect this magnet and enters auto trigger mode. The scanner starts scanning automatically when
it detects a change in brightness that occurs when a bar code label is presented in front of it.

Figure 8: Stand Detection Flow
* The dedicated stand needs to be purchased separately if auto trigger is used.
* Auto trigger is disabled by default and needs to be enabled if it is used.
