codes, stacked codes and DataMatrix codes as well as for codes of the GS1DataBar family.
Areas of application
The code readers of the DCR200i series are especially designed for the following areas of application:
• Packaging systems
• Mounting/handling technology
• Analysis technology
CAUTION
Observe intended use!
The protection of personnel and the device cannot be guaranteed if the device is operated in a
manner not complying with its intended use.
ÄOnly operate the device in accordance with its intended use.
ÄLeuzeelectronicGmbH+Co.KG is not liable for damages caused by improper use.
ÄRead these operating instructions before commissioning the device. Knowledge of the oper-
ating instructions is an element of proper use.
NOTICE

3 Device description
3.1 Device overview
3.1.1 About the DCR200i code reader
The code readers of the DCR200i series are camera-based code readers for all commonly used bar
codes, stacked codes and Data Matrix codes (e.g. Code128, EAN8/13, ECC200, QR etc.) as well as for
codes of the GS1DataBar family.
The extensive options for device configuration via control buttons, configuration codes or software enable
adaptation to a multitude of reading tasks. The high resolution in combination with a very high depth of field
as well as the compact design make the device ideal for use in packaging machines.
Code readers of the DCR200i series perform numerous tasks in industrial code reading such as:
• Omnidirectional code reading
• Reading of codes while at a standstill or in motion
• Manual reading by holding up codes
• In packaging machines
• In automatic handling and testing machines
The DCR2xxi code readers are available in several optics models:
• DCR2xxi with HighDensity optics (N-optics)
• DCR2xxi with MediumDensity optics (M optics)
• DCR2xxi with LowDensity optics (F optics)
The DCR2xxi code readers are operated as a “stand-alone” single device with individual IP address in an
Ethernet star topology.
Information on technical data and characteristics: see chapter 14 "Technical data".
3.1.2 Performance characteristics
• Decoding of 1D-, stacked- and 2D-codes
• Maximum depth of field and reading distance of approx. 40mm…360mm
• High object speed and decoding performance of up to 7m/s with 10decodings
• Reference code comparison
• Quality evaluation of 1D bar codes and 2D-codes in accordance with ISO/IEC15415 and ISO/
