3 Device description
3.1 Device overview
3.1.1 About the DCR85 code reader
The code reader is based on a CMOS imager with integrated decoder for all of the most popular 1D and 2D
codes such as DataMatrix, Aztec, QRCode, 2/5 Interleaved, Code39, Code128, 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 scan engine can also be used in highly
constrained spaces.
Information on technical data and characteristics: see chapter 11 "Technical data".
3.1.2 Stand-alone operation
The code reader is operated as a "stand-alone" single device. It is equipped with a 6-wire cable with open
ends for the electrical connection of the supply voltage, the interface, the trigger input and the switching
output.
3.2 Performance characteristics
• High-performance, miniature CMOS Imager with front beam exit
• 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, one triggering input, one switching output

You can fasten the code reader at the M2.5 mounting threads.
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 account the different reading characteristics of the scanner with various code modules.
NOTICE
Observe when choosing the mounting location!
Ä Maintaining the required environmental conditions (temperature, humidity).
Ä Possible soiling of the reading window due to liquids, abrasion by boxes, or packaging mate-
rial residues.
Ä Lowest possible chance of damage to the scanner by mechanical collision or jammed parts.
Ä 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 or Data Matrix codes on the objects to be
scanned.
• The reading field of the code reader in relation to the code module width.
• The resulting minimum and maximum reading distance from the respective reading field (see chapter
11.2 "Reading fields").
• Alignment of the code reader for avoiding reflections.
• Distance between code reader and host system with respect to the interface.
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.
Mounting
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.

β Angle of inclination

5 Electrical connection
CAUTION
Safety notices
Ä Before connecting the device, be sure that the supply voltage agrees with the value printed
on the name plate.
Ä Connection of the device and maintenance work while under voltage must only be carried
out by a qualified electrician.
Ä The power supply unit for the generation of the supply voltage for the code reader and the
corresponding connection units must have a secure electrical insulation according to
IEC60742 (PELV). For UL applications: only for use in class 2 circuits according to NEC.
Ä If faults cannot be cleared, the device should be switched off and protected against acciden-
tal use.
5.1 Voltage supply
The code reader is designed for connection to a 5V supply voltage.
• +5V DC (red)
• GND (violet)
An adapter circuit board with spring terminals, Molex plug connector and 9-pin SUB-D socket is available
as an accessory (see chapter 12.2 "Accessories").
• With the adapter circuit board, the conductors of the connection cable can be contacted via the spring
terminals and connected to the PC via the 9-pin SUB-D socket with an RS 232 interconnection cable.
• With the adapter circuit board, the voltage supply of 10…30V DC can be fed in via spring terminals
or, alternatively, 5V DC can be fed in via a micro USB connector.

Via the serial interface, you can configure the code reader by means of a PC or terminal. For this, you need
an RS232 connection that establishes the RxD, TxD and GND connections between PC and code reader.
The RS232 connection can be established in the following ways:
• Direct connection of the 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 "Accessories").
