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 202i code readers are available in several optics models:
• DCR 202i FIX-N1-102-R3 with high-density optics (N-optics)
• DCR 202i FIX-M1-102-R3 with medium-density optics (M-optics)
• DCR 202i FIX-F1-102-R3 with low-density optics (F-optics)
The DCR 202i code readers are operated as a stand-alone single device with individual IP address in an
Ethernet star topology.

This chapter describes the functions of the code reader:
• Camera operating modes; see chapter 4.1
• Reference code comparison; see chapter 4.2
• webConfig tool; see chapter 4.3
4.1 Camera operating modes
The camera operating mode defines how the code reader starts a read process and decodes the codes if
a code is located in the read field.
4.1.1 Single trigger mode
In the Single trigger mode camera operating mode, the code reader captures
decode it. Under uniform conditions, this camera operating mode makes fast decoding possible.
4.1.2 Reading gate control
The Reading gate control camera operating mode is activated upon shipment from the factory. The
reading gate control opens a time window for the read process in the code reader – the reading gate. In
this time window, the code reader can capture and decode one or more codes.

4.1.3 Burst mode
In the Burst mode camera operating mode, the code reader captures
after activation by a trigger signal. Decoding occurs following image capture, thereby allowing the codes
to be detected more quickly. As soon as the decoding result corresponds to the settings, the decoding
stops the capture of the remaining images.

Figure 4.1: Burst mode
4.1.4 Presentation mode
In the Presentation mode camera operating mode, the code reader is in the idle state in a kind of wait
mode.
In the event of a change in the image area, e.g., by holding up a code, the code reader captures images
with illumination (as previously configured) until a code is read successfully. The code reader then
Leuze electronic DCR 202i 16
switches back to the wait mode and the illumination switches off after a few seconds.

6 Mounting
The code reader can be mounted in the following ways:
• Mounting using four M4 mounting threads on the rear of the device
• Mounting using two M4 mounting threads on each of the side surfaces of the device
• Mounting on a 12 mm rod using the BTU 320M-D12 mounting system
• Mounting on the BT 320M mounting bracket
6.1 Determining the mounting position of the code reader
6.1.1 Selecting a mounting location
The size of the code module influences the maximum reading distance and the width of the read-
ing field. Therefore, when selecting a mounting location and/or the suitable code label, take into
account the different reading characteristics of the code reader with various code modules.
NOTICE
Observe when choosing the mounting location!
Make certain that the required environmental conditions (humidity, temperature) are maintained.
Avoid possible soiling of the reading window due to liquids, abrasion by boxes, or packaging material
residues.
Ensure the lowest possible chance of damage to the code reader through mechanical collision or
jammed parts.
Avoid possible ambient light influence (no direct sunlight).
Mounting
Take the following factors into account when selecting the correct mounting location:
• Size, orientation, and position tolerance of the bar codes or Data Matrix codes on the objects to be
scanned.
• The reading distance resulting from the code size and code type (see chapter 6.1.3 "Determining the
reading distance").
• Time of data output.
Position the device in such a way that, taking into consideration the time required for data processing
and the conveyor belt speed, there is sufficient time to e.g. initiate sorting operations on the basis of
the read data.
• The permissible line lengths between code reader and host system depending on which interface is
used.
• Visibility of the control panel and access to the control buttons.
• No direct sunlight and/or no strong ambient light on the code that is to be read.
Observe the following criteria for the best read results:
• The reading distance is located in the middle part of the read field (see chapter 6.1.3 "Determining
the reading distance").
• There is no direct sunlight and protect against ambient light effects.
• The code labels are of good print quality and have good contrast ratios.
• Do not use glossy labels.
• The bar code or DataMatrix code is moved past the reading window with a tilt angle or angle of inclination of 10° … 20° (see chapter 6.1.2 "Avoiding total reflection").
6.1.2 Avoiding total reflection
If the illumination light of the code reader is directly incident on the surface of the code at an angle of 90°,
total reflection occurs. The illumination light directly reflected by the code label may overload the code
reader and thereby result in non-reading of the code.
Mount the code reader with a tilt angle or angle of inclination of ±10° … 20° from vertical.

6.1.3 Determining the reading distance
In general, the read field of the code reader becomes larger with increasing reading distance. This also
results in a decrease in the resolution, however.
The following figures show typical reading distances for the individual optics models of the code reader.
Mounting
Code reading while in motion is dependent on the code type, code size, cell or modulus size of
the code and the position of the code in the read field of the code reader.
For the relationship between camera distance and read field see figure 6.6.
Reading distances for code readers with N-optics
Please note that the actual reading distances are also influenced by factors such as labeling
material, printing quality, reading angle, printing contrast etc., and may thus deviate from the
reading distances specified here.

8.3 Setting the communication parameters
With the communication parameters, you determine how data is exchanged between device and host
system, monitor PCs etc.
8.3.1 Manually setting the IP address
Set the IP manually if your system does not include a DHCP server or if the IP addresses of the devices
are to be set permanently.

function on the control panel.
8.3.3 Address Link Label
The Address Link Label is an additional stick-on label that is affixed to the device.
Figure 8.1: Example of an Address Link Label; the device type varies depending on the series
• The Address Link Label contains the MAC address (Media Access Control address) of the device
and makes it possible to enter the IP address and the device name manually.
The area of the Address Link Label on which the MAC address is printed can be separated from the
remainder of the stick-on label if necessary using the perforation.
• The Address Link Label can be removed from the device and affixed in the installation and layout
diagrams to designate the device.
• Once it is affixed in the documents, the Address Link Label establishes a unique reference between
the mounting location, the MAC address or the device, and the associated control program.
There is no need for time-consuming searching, reading, and manually writing down of the MAC
addresses of every device that is installed in the system.
Leuze electronic DCR 202i 37
Page 38
Each device with Ethernet interface is uniquely identified via the MAC address assigned during
production. The MAC address is also listed on the name plate of the device.
If multiple devices are commissioned in a system, the MAC address of each installed device
must be correctly assigned, e.g., during programming of the control.
8.3.4 Ethernet host communication
You can configure the connections to an external host system via the Ethernet host communication.
You can use both the UDP protocol as well as the TCP/IP protocol – in either client or in server mode. Both
protocols can be activated simultaneously and used in parallel.
• The connection-free UDP protocol is used primarily to transfer process data to the host (monitor
operation).
• The connection-oriented TCP/IP protocol can also be used to transfer commands from the host to
the device. With this connection, the data is backed up by the TCP/IP protocol itself.
• If you would like to use the TCP/IP protocol, you must also define whether the device is to operate as
a TCP client or as a TCP server.
UDP
The device requires from the user the IP address and the port number of the communication partner. In
the same way, the host system (PC/control) also requires the set IP address of the device and the selected
port number. By assigning these parameters, a socket is formed via which the data can be sent and
received.
Activate the UDP protocol.
Set the following values:
Starting up the device - Basic configuration
• IP address of the communication partner
• Port number of the communication partner
The corresponding adjustment options can be found in the webConfig tool:
Configuration > Control > Host > Ethernet > UDP
TCP/IP
Activate the TCP/IP protocol.
Set the TCP/IP mode of the device.
• In TCP client mode, the device actively establishes the connection to the superior host system, e.g.,
PC/control as server. The device requires from the user the IP address of the server (host system)
and the port number on which the server (host system) accepts a connection. In this case, the device
determines when and with whom a connection is established.
• In TCP server mode, the superior host system (PC/control) actively establishes the connection and
the connected device waits for the connection to be set up. The TCP/IP stack must be informed by
the user as to the local port of the device (port number) on which connection requests from a client
application (host system) are to be received. If there is a connection request and a connection is
established by the superior host system (PC/control as client), the device – in server mode – accepts
the connection. Data can then be sent and received.
With a device as TCP client, set the following values:
• IP address of the TCP server, normally the IP address of the control or the host computer
• Port number of the TCP server
• Timeout for the wait time for an answer from the server
• Repetition time for renewed communication attempt following a timeout
With a device as TCP server, set the following values:
• Port number for the communication of the device with the TCP clients
The corresponding adjustment options can be found in the webCon
fig tool:

8.6.4 Control of the switching outputs
By using the switching inputs/outputs of the device, external event-controlled functions can be implemented without assistance from the superior process control. Switching inputs/outputs SWO2, SWIO3 and
SWIO4 on the PWR / SWIO connection must be configured as switching output for this purpose (see
chapter 7.2).
A switching output can, for example, be activated according to the following criteria:
• At the start/end of the reading gate
• Upon actuation by an external flash
• Depending on the read result:
• Reference code comparison positive/negative
• Read result valid/invalid

Commands can be used to send commands directly to the code reader for control and configuration. The
following transmission options are available for the commands:
• Online commands via the Ethernet or RS 232/RS 422 interface (see chapter 10.1 "Online commands")
• XML-based communication via the Ethernet interface (see chapter 10.2 "XML-based communication")
10.1 Online commands
10.1.1 Overview of commands and parameters
Online commands can be used to send commands directly to the code reader for control and configuration.
For this, the code reader has to be connected to a computer (host) via the serial interface or the Ethernet
interface (see chapter 8.3.4 "Ethernet host communication").
Online commands offer the following options for controlling and configuring the code reader:
• Control/decode the reading gate
• Read/write/copy parameters
• Carry out an automatic configuration
• Teach-in/set reference codes
• Call up error messages
• Query statistical device information
• Perform a software RESET and re-initialize the code reader
