DATALOGIC DS4300 2.4.5 Outputs The following pins are present on the 25-pin connector of the scanner: Pin 8 22 11 12 Name OUT1+ OUT1OUT2+ OUT2- Function output 1 + output 1 output 2 + output 2 - The meaning of the two outputs OUT1 and OUT2 can be defined by the user (No Read, Right or Wrong). Refer to WinHost Help On Line. By default, OUT1 is associated with the No Read event, which activates when the code signalled by the External Trigger is not decoded.
DS4300 DATALOGIC 2.5 POSITIONING The DS4300 scanner is able to decode moving barcode labels at a variety of angles, however significant angular distortion may degrade reading performance. When mounting the DS4300 take into consideration these three ideal label position angles: Pitch 0°, Skew 10° to 30° and Tilt 0°. Follow the suggestions below for the best orientation: P The Pitch angle is represented by the value P in figure 2.25. Position the reader in order to minimize the Pitch angle. Figure 2.
DATALOGIC DS4300 2.6 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.
DS4300 DATALOGIC 2.6.2 Pass Through Pass through mode allows two or more devices to be connected to a single external serial interface. Each DS4300 transmits the messages received by the auxiliary interface onto the main interface. All messages will be passed through this chain to the host. When On-Line Operating mode is used, the scanner is activated by an External Trigger (photoelectric sensor) when the object enters its reading zone.
DATALOGIC DS4300 2.6.3 RS232 Master/Slave The RS232 master/slave connection is used to collect data from several scanners to build either an omni-directional or a multi-sided reading system; there can be one master and up to 9 slaves connected together. The Slave scanners use RS232 only on the main and auxiliary serial interfaces. Each slave DS4300 transmits the messages received by the auxiliary interface onto the main interface. All messages will be passed through this chain to the Master.
DS4300 DATALOGIC 2.6.4 RS485 Master/Slave The RS485 master/slave connection is used to collect data from several scanners to build either an omni-directional or a multi-sided reading system; there can be one master and up to 5 slaves connected together. The Slave scanners are connected together using RS485 half-duplex on the main serial interface. Every Slave scanner must have a multidrop address in the range 0-4. The Master scanner is also connected to the Host on the RS232 auxiliary serial interface.
DATALOGIC DS4300 NOTE The auxiliary serial interface of the slave scanners can be used in Local Echo communication mode to control any single scanner (visualize collected data) or to configure it using the WinHost utility or Host Mode Programming procedure. The termination resistors of the RS485 bus must not be installed. 2.6.5 Multiplexer Each scanner is connected to an MX4000 with the RS485 half duplex mode on the main interface.

DATALOGIC DS4300 3 READING FEATURES 3.1 ADVANCED CODE RECONSTRUCTION The traditional way of barcode reading could be called "Linear Reading". In this case, the laser beam crosses the barcode symbol from its beginning to its end as shown in Figure 3.1. Laser Beam Figure 3.1 - Linear reading In “Advanced Code Reconstruction” mode, it is no longer necessary for the laser beam to cross the label from the start to the end.
DS4300 DATALOGIC 3.1.1 Tilt Angle for Advanced Code Reconstruction The most important parameter in Advanced Code Reconstruction is the value of the maximum tilt angle (α maximum) under which the code reconstruction process is still possible. We define the Tilt angle as the angle (α) between the laser beam and a line parallel to the barcode label, as shown in Figure 3.3. Laser Beam 0° to α max α = tilt angle α Figure 3.
DATALOGIC DS4300 3.2 DECODING CAPACITY IN LINEAR MODE When in Linear Reading mode, the number of reads performed by the DS4300 and therefore the decoding capacity, 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. 3.2.1 Step Ladder Mode Code motion moving at LS speed DS4300 LH Laser Beam Figure 3.
DS4300 DATALOGIC For example, the DS4300 (800 scans/sec.), for a 25 mm high code moving at 1250 mm/s performs: [(25/1250) * 800] - 2 = 14 effective scans. 3.2.2 Picket Fence Mode Laser Beam Code motion moving at LS speed DS4300 LW FW Figure 3.6 - "Picket Fence" scanning mode If scanning is parallel to the code motion, (Figure 3.
DATALOGIC DS4300 3.3 PERFORMANCE The DS4300 scanner reads codes with densities from 0.20 mm (8 mils) to 1.00 mm (40 mils) in the zone between 50 mm (1.9 in) and 400 mm (15.7 in) from the emission window. DS4300 can be optimized for reading high density codes (between 0.20 mm (8 mils) and 0.30 mm (12 mils) by configuring the Code Resolution parameter (see WinHost Help On Line). Refer to the diagrams given in paragraph 3.4 for further details on the reading features.
DS4300 DATALOGIC 3.4 READING DIAGRAMS The following diagrams show the reading distance for barcodes with different densities. DS4300-100X (Code Resolution Standard) 0.50 mm (20 mils) 0.60 mm (24 mils) ≥ 0.80 mm (31 mils) NOTE: (0,0) is the center of the laser beam output window CONDITIONS: Test Codes used "Pitch" angle "Skew" angle "Tilt" angle Reading Mode Code Resolution 3.
