Chapter 1: ABSTRACT
1 Abstract
This manual provides specifications for the SC312 2D barcode scanner.
2 Overview
The SC312 is a 2D barcode scanner that enables high speed scanning of high
resolution linear (1D) and 2D symbologies. Main features of the SC312 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
Set the auto trigger detection and using the dedicated stand (optional
accessory), 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.
•LED aiming
A sharp single line of green LED makes it easy to aim the scanner while
providing safety and long-life.
•Setting tool
“UniversalConfig” is ready to use and it makes installation easy.
•Various interfaces
SC312 and host is connected by USB (HID or COM) or RS-232C interface.
Exchanging cable and changing setting, RS-232C specification product can be
use as USB specification. And USB multi-interface specification product can
be use as RS-232C specification by exchanging cable and changing setting.

Chapter 4: ELETRICAL SPECIFICATIONS
The SC312 comprises of a ‘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 power adapter is needed. The
RS-232C models need a dedicated adapter for DC 5.0 V power. Make sure not
to insert and remove the power adapter when the PC is on. It may cause the
PC to malfunction.

5-2 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=112±40 mm from the front edge of the
scanner.
- The horizontal aiming width to the horizontal width of imaging field of view
at a distance of L=112 mm is 90%±10%.
- The aiming at the distance of L=27 mm is the sharpest and clearest.
