Device description
3Device description
3.1Device overview
3.1.1The DCR 80 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 scan engine can also be used in highly constrained spaces.
Information on technical data and characteristics: see chapter 11.
3.1.2Stand alone operation
The scan engine is operated as a single “stand-alone” device. It is equipped with a 12-pin Molex plug connector for the power supply electrical connection, the interface, the trigger input and the switching output.
3.2Performance 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, buzzer output (GOOD READ)

Mounting
4Mounting
The scan engine can be attached at four studs with an M2 internal thread.
4.1Selecting a mounting location
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!
Maintaining the required environmental conditions (temperature, humidity).
Possible soiling of the reading window due to liquids, abrasion by boxes, or packaging material residues.
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 or Data Matrix codes on the objects to be scanned.
•The reading field of the scan engine depends on the code module width.
•the resulting minimum and maximum reading distance from the respective reading field; see figure 11.1.
•Scan engine alignment for avoiding reflections.
•Distance between scan engine and host system with respect to the interface.
It is advisable to use a transparent, double-sided anti-reflective coated material when installing the scan engine behind a pane of glass. Recommended pane thickness: 1 mm; optics as flush as possible with the glass.
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 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.
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.

Electrical connection
5Electrical connection
CAUTION
Safety notices
Before connecting the device, be sure that the supply voltage agrees with the value printed on the name plate.
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 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.
If faults cannot be corrected, the device should be removed from operation and protected against possible commissioning.
5.1Voltage supply
The scan engine is designed for connection to a 5 V supply voltage.
•+5 V DC (pin 1)
•GND (pin 2)
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 12-pin plug 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 9-pin SUB-D socket using an RS 232 interconnection cable.
•With the adapter circuit board, the voltage supply of 10 … 30 V DC can be fed in via spring terminals or, alternatively, 5 V DC can be fed in via a micro USB connector.

5.3Switching input/Switching output
The scan engine has a switching input and a switching output.
•The switching input is used to trigger reading.
•The switching output signals successful code reading.
•An additional BUZZER output supplies a modulated signal for connecting a buzzer. The buzzer signals successful code reading.
5.3.1Switching 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; see figure 5.1.

Electrical connection
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 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 the 12-pin plug connector to SUB-D, 9-pin; see chapter 12.2.

5.5Cable lengths and shielding
The maximum cable length is 3 m.
Should a cable extension be necessary, make certain that the cables of the RS 232 interface are shielded.
