3 Device description
3.1 Device overview
3.1.1 About the DCR50 scanengine
The code reader is based on a scan engine with CMOS imager with integrated decoder for all of the most
popular 1D and 2D codes such as DataMatrix, Aztec, QRCode, 2/5 Interleaved, Code39, Code128, UPC/
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 the large reading field, the device can also be used in highly con-
strained spaces.
Information on technical data and characteristics: see chapter 12 "Technical data".
3.1.2 Stand-alone operation
The scan engine is operated as a single "stand-alone" device. It is equipped with a 6-pin Molex connector
for the power supply electrical connection, the interface, the trigger input, and the switching output.
3.2 Performance characteristics
• High-performance miniature CMOS imager scan engine
• Compact design for simple integration, even in constrained spaces
• Reading of extremely small high-density codes and recording of standard codes in a large reading area
using a special optical system
• Reading of shiny surfaces using a gloss reduction process
• Excellent decoding characteristics
• Clearly visible alignment LED
• RS 232 interface, triggering input, switching output

4 Mounting
The scan engine can be attached at two M2.5 through-hole mounting tabs.
In addition, two 2mm deep inserts for M1.8 self-tapping screws are provided on top of the scan engine.
4.1 Selecting a mounting location
NOTICE
The size of the code module influences the maximum reading distance and the width of the
reading field. Therefore, when selecting a mounting location and/or the code label, take into ac-
count the different reading characteristics of the scanner with various code modules.
NOTICE
Observe when choosing the mounting location!
ÄMaintaining the required environmental conditions (temperature, humidity).
ÄPossible soiling of the reading window due to liquids, abrasion by boxes, or packaging mate-
rial residues.
ÄLowest possible chance of damage to the scanner by mechanical collision or jammed parts.
ÄPossible extraneous light influence (no direct sunlight).
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 or the Data Matrix code is moved past the reading window with an angle of rotation of 10°
to 15°.
• the red light beam is narrowed down for its respective reading task in order to avoid reflections on shiny
components.
NOTICE
The front beam exit of the scan engine is almost vertical to the optics. The code label must be
rotated by >10° to avoid a total reflection of the red light beam in the case of glossy labels.

5 Electrical connection
CAUTION
Safety notices
ÄBefore connecting the device, be sure that the supply voltage agrees with the value printed
on the name plate.
ÄConnection of the device and maintenance work while under voltage must only be carried
out by a qualified electrician.
ÄThe power supply unit for the generation of the supply voltage for the scan engine and the
corresponding 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.
ÄIf faults cannot be cleared, the device should be switched off and protected against acciden-
tal use.
5.1 Voltage supply
The scan engine is designed for connection to a 5V supply voltage.
• +5V DC (pin1)
• GND (pin2)
A MA-CR Modular adapter unit (interface device-to-host to connect to a PC for evaluation, 50128204) with
spring terminals, Molex connector, and D-SUB 9-pin socket is available as an accessory (see chapter 13.2
"Accessories").
• With the MA-CR Modular adapter unit, the 6-pin connector of the scan engine can be contacted via a
150mm long interconnection cable with a 12-pin Molex terminal strip and connected to the PC via the
D-SUB 9-pin socket using an RS 232 interconnection cable.
• With the MA-CR Modular adapter unit, the voltage supply of 10…30V DC can be fed in via spring ter-
minals or, alternatively, 5V DC can be fed in via a micro USB connector.

5.3 Switching input / switching output
The scan engine has a switching input and a switching output.
• The switching input is used to trigger code reading.
• The switching output signals successful code reading.
5.3.1 Switching input
A read process can be triggered using the trigger input (pin5) in the standard setting (low = active) via the
connection to GND (pin2). We recommend wiring a 2.2kΩ pull-up resistor as defined cable termination.

5.4 PC or terminal connection
Via the serial interface, you can configure the scan engine by means of a PC or terminal. For this, you need
a RS232 connection that establishes the RxD, TxD and GND connections between PC and scan engine.
The RS232 connection can be established in the following ways:
• Direct connection of the plug connector of the scan engine to the PC or terminal via its own connector.
• Connection via a MA-CR modular adapter unit
To simplify the connection of the connection wires to the PC interface, a modular adapter unit (MA-CR)
is available for implementing the 6-pin plug connector to D-SUB, 9-pin (see chapter 13.2 "Acces-
sories").
