3.1 Device overview

3.1.1 The CR 55 bar code reader

Device description

The bar code reader is a CCD based
codes, e.g. 2/5 Interleaved, Code 39, Code 128, EAN etc.

The many possible configurations of the device allow it to be adapted to a multitude of reading tasks. Due
to the small dimensions of the unit and its large reading field, the bar code reader can also be used in highly
constrained spaces.

Information on technical data and characteristics: see chapter 11.

3.1.2 Stand alone operation

The bar code reader is operated as a “stand-alone” single device.
open ends for the electrical connection of the supply voltage, the interface, the switching input and the
switching output.

3.2 Performance characteristics

• High-performance CCD scanner with front beam exit

• Compact design for simple integration, even in constrained spaces

• Robust metal housing with cable connection

• RS 232 interface, one switching input, one switching output

4 Mounting

α

β

γ

You can fasten the bar code reader at the M2.5 mounting threads.

4.1 Selecting a mounting location

The size of the bar code module influences the maximum reading distance and the width of the
reading field. Therefore, when selecting a mounting location and/or the bar code label, take into
account the different reading characteristics of the scanner with various bar code modules.

NOTICE

Observe when choosing the mounting location!

 Maintaining the required environmental conditions (temperature, humidity).

 Possible soiling of the reading window due to liquids, abrasion by boxes, or packaging material resi-

dues.

 Lowest possible chance of damage to the scanner by mechanical collision or jammed parts.

 Possible extraneous light influence (no direct sunlight).

In order to select the right mounting location, several factors must be considered:

• size, orientation, and position tolerance of the bar codes on the objects to be scanned.

• The reading field of the bar code reader in relation to the bar code module width.

• The bar code reader is designed for reading codes in ladder orientation.

• the resulting minimum and maximum reading distance from the respective reading field; see
figure 11.1.

• alignment of the bar code reader for avoiding reflections.

• distance between bar code reader and host system with respect to the interface.

Mounting

The best read results are obtained when

• the reading distance lies in the middle area of the reading field.

• there is no direct sunlight and extraneous light is avoided.

• the bar code labels are of good print quality and have good contrast ratios.

• you do not use high-gloss labels.

• the bar code is moved past the reading window with a rotational angle of 10° to 15°.

• the red light beam is narrowed down for its respective reading task in order to avoid reflections on
shiny components.

With front-side beam exit, the beam exits the bar code reader nearly perpendicular to the reading
window. The bar code label must be rotated by > 10° to avoid a total reflection of the red light
beam in the case of glossy labels.

 Connection of the device and maintenance work while under voltage must only be carried out by a

qualified electrician.

 The power supply unit for the generation of the supply voltage for the bar code reader and the corre-

sponding connection units must have a secure electrical insulation according to IEC 60742 (PELV).
For UL applications: only for use in “class 2” circuits according to NEC.

 If faults cannot be corrected, the device should be removed from operation and protected against pos-

sible commissioning.

Maximum loading of the switching output

 Do not load the switching output of the bar code reader with more than 20 mA at +5 … 30 V DC!

Via the serial interface, you can configure the bar code reader by means of a PC or terminal. For this, you
need an RS 232 connection that establishes the RxD, TxD and GND connections between PC and bar
code reader.

The RS 232 connection can be established in the following ways:

• Direct connection of the bar code reader connection wires to the PC or terminal via its own connec­tor.

• Connection via an MA-CR adapter circuit board
To simplify the connection of the connection wires to the PC interface, an adapter circuit board (MA­CR) is available for implementing individual wire contacting to SUB-D, 9-pin; see chapter 12.2.

7.3 Setting the communication parameters

You have now commissioned the bar code reader. Usually, you will have to configure it before you can
use it. Using the configuration options offered in the
bar code reader can be individually configured according to your application. For information on the
various configuration options, see chapter 6 or refer to the online help.

To operate the bar code reader, it is normally sufficient to set code type and code length in accordance
with the bar codes that are to be read.

The setting of code type and code length is usually accomplished by using the
software, see chapter 6.

The various parameter sets are explained in brief to understand what is happening during parameter
setting, see chapter 7.3.1.

The parameters are then set using the buttons under CONFIGURATION. To transfer the settings to the
bar code reader, its RS 232 settings must be set to the “Service” operating mode, see chapter 7.3.2.

It is permanently stored in the FLASH ROM of the bar code reader.

The parameter set with the default settings is loaded into the memory of the bar code reader:

• the first time the device is commissioned after delivery

• following the command “Factory Default” in the configuration program (online command ’PC20’)

• if the checksums of the current parameter set are invalid

Current parameter set
In this parameter set, the current settings for all device parameters are stored. When the bar code reader

is in operation, the parameter set is stored in the EEPROM of the bar code reader.

Leuze electronic CR 55 22

The current set can be stored:

• by copying a valid parameter set from the host computer in the bar code reader

• by an off-line setup using the
the bar code reader

The current parameter set is loaded into the memory of the bar code reader:

• by a parameter command, see chapter "Parametersatz kopieren"

7.3.2 “Service” operating mode

You can connect a PC or a terminal to the bar code reader via the serial interface and configure the bar
code reader through this connection; see chapter 5.4 "PC or terminal connection".

Setting the required parameters is most easily carried out in the “Service” operating mode.

The operating mode “Service” provides the following defined operating parameters on the RS 232 inter­face, no matter how the bar code reader is configured for standard operation:

• transmission rate: 9600 baud

• no parity

• 8 data bits

• 1 stop bit
