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 15 "Technical data".
