SAFETY PRECAUTIONS LASER SAFETY The following information is provided to comply with the rules imposed by international authorities and refers to the correct use of the DS2200 scanner. Standard Regulations This scanner utilizes a low-power laser diode. Although staring directly at the laser beam momentarily causes no known biological damage, avoid staring at the beam as one would with any very strong light source, such as the sun.
The warning label indicating exposure to laser light and the device classification is applied onto the body of the scanner (Figure A, 8): LASER LIGHT DO NOT STARE INTO BEAM CLASS 2 LASER PRODUCT MAX. OUTPUT RADIATION 1 mW EMITTED WAVELENGTH 630~680 nm TO EN 60825-1:2001 CAUTION-CLASS 3B LASER LIGHT WHEN OPEN AVOID EXPOSURE TO BEAM This product conforms to the applicable requirements of 21CFR1040 at the date of manufacture.

GUIDE TO INSTALLATION The following can be used as a checklist to verify all the necessary steps for complete installation of the DS2200 scanner. 1. Read all information in the section "Safety Precautions” at the beginning of this manual. 2) Correctly mount the reader using the bracket provided according to the information in par. 2.2.1. 3) Position the reader at the correct reading distance according to your model as shown in par. 3.4.
INTRODUCTION 1 1.1 1 INTRODUCTION PRODUCT DESCRIPTION The DS2200 scanner is a cost effective barcode reader complete with decoder designed to satisfy demanding requirements associated with high performance scanning. The DS2200 ultra compact dimensions, based on Datalogic's experience in miniaturized laser components, make the scanner's integration into automated equipment extremely easy.
DS2200 1 A security system allows the laser to activate only once the motor has reached the correct rotational speed; consequently, the laser beam is generated after a slight delay from the power on of the scanner. 1.1.1 Indicators The four LEDs on the scanner indicate the following: POWER ON (red), indicates the reader is connected to the power supply. (Figure A, 3). GOOD READ (red), is used to signal the possibility of a successful barcode reading. (Figure A, 4).

INSTALLATION 2.3 2 ELECTRICAL CONNECTIONS The DS2200 cable is equipped with a 25-pin female D-sub connector for connection with the power supply and input/output signals: CAUTION Do not connect GND and SGND to different (external) ground references. GND and SGND are internally connected through filtering circuitry which can be permanently damaged if subjected to voltage drops over 0.8 Vdc.
DS2200 2 2.3.1 Power Supply The following pins of the DS2200 connector are used: DS2200 USER INTERFACE 13/9 VS V+ (5 Vdc) 25 GND GND 1 CHASSIS Figure 4 - Power supply connections The power must be 5 Vdc only. 2.3.2 Main Serial Interface - RS485 Half-Duplex The RS485 half-duplex interface (3 wires + shield) is used for polled communication protocols. It can be used for Multidrop connections in a master/slave layout, or with a Datalogic Multiplexer (see par. 2.6.2 and 2.6.3).

The active state of this input is selected in software. Refer to the WinHost Help On Line.
INSTALLATION 2.3.5 2 Outputs Two general purpose outputs are available. These outputs can only be connected as open collector configurations. The following pins are present on the connector of the scanner: Pin Name 8 OUT1+ 11 OUT2+ 10, 12, 22 I/O REF Function output 1 + output 2 + I/O reference The meaning of the two outputs OUT1 and OUT2 can be defined by the user (No Read, Right or Wrong). Refer to the WinHost Help On Line.
DS2200 2 2.4 USER INTERFACE The following table contains the pinout for standard RS232 PC Host interface. For other user interface types, please refer to their own manual.
INSTALLATION 2.5 2 POSITIONING The DS2200 scanner is able to decode barcode labels at a variety of angles, however significant angular distortion may degrade reading performance. When mounting the DS2200 take into consideration these three ideal label position angles: Pitch 0°, Skew 15° to 30° and Tilt 0°. Follow the suggestions for the best orientation: The Pitch angle is represented by the value P in Figure 10. Position the reader in order to minimize the Pitch angle.
DS2200 2 The Tilt angle is represented by the value T in Figure 12. Position the reader in order to minimize the Tilt angle.
INSTALLATION 2.6 2 TYPICAL LAYOUTS The following typical layouts refer to system hardware configurations. Dotted lines in the figures refer to optional hardware configurations within the particular layout. These layouts also require the correct setup of the software configuration parameters. Complete software configuration procedures can be found in the Guide To Rapid Configuration in the WinHost Help On Line. 2.6.
DS2200 2 The Master scanner is also connected to the Host on the RS232 auxiliary serial interface. The External Trigger signal is unique to the system; there is a single reading phase and a single message from the Master scanner to the Host computer. It is necessary to bring the External Trigger signal to all the scanners. The main and auxiliary ports are connected as shown in the figure below.
INSTALLATION 2.6.3 2 Multiplexer Each scanner is connected to a Multiplexer (for example MX4000) with the RS485 half-duplex main interface.
DS2200 3 3 READING FEATURES The number of scans performed on the code by the DS2200 and therefore the decoding capability is influenced by the following parameters: • number of scans per second • code motion speed • label dimensions • scan direction with respect to code motion At least 5 scans during the code passage should be allowed to ensure a successful read. 3.
READING FEATURES 3 For example, the DS2200 (500 scans/sec.) for a 25 mm high code moving at 500 mm/s performs: [(25/500) * 500] - 2 = 23 effective scans. 3.

MAINTENANCE 4 4.1 4 MAINTENANCE CLEANING Clean the windows periodically for continued correct operation of the reader. Dust, dirt, etc. on the windows may alter the reading performance. Repeat the operation frequently in particularly dirty environments. Use soft material and alcohol to clean the windows and avoid any abrasive substances. Clean the windows of the DS2200 when the scanner is turned off or, at least, when the laser beam is deactivated.

GLOSSARY Aperture Term used on the required CDRH warning labels to describe the laser exit window. Barcode A pattern of variable-width bars and spaces which represents numeric or alphanumeric data in machine-readable form. The general format of a barcode symbol consists of a leading margin, start character, data or message character, check character (if any), stop character, and trailing margin. Within this framework, each recognizable symbology uses its own unique format.
EEPROM Electrically Erasable Programmable Read-Only Memory. An on-board non-volatile memory chip. Full Duplex Simultaneous, two-way, independent transmission in both directions. Half Duplex Transmission in either direction, but not simultaneously. Host A computer that serves other terminals in a network, providing services such as network control, database access, special programs, supervisory programs, or programming languages.
Protocol A formal set of conventions governing the formatting and relative timing of message exchange between two communicating systems. Raster The process of projecting the laser beam at varied angles spaced evenly from each other. Typically, the mirrored rotor surfaces are angled to create multiple scan lines instead of a single beam. Resolution The narrowest element dimension which can be distinguished by a particular reading device or printed with a particular device or method.
Tilt Rotation around the Z axis. Used to describe the position of the barcode with respect to the laser scan line. See pars. 2.2.1 and 2.5. Trigger Signal A signal, typically provided by a photoelectric sensor or proximity switch, which informs the scanner of the presence of an object within its reading zone. UPC Acronym for Universal Product Code. The standard barcode type for retail food packaging in the United States. Visible Laser Diode A light source used in scanners to illuminate the barcode symbol.
