DS4600A 2 2.5 POSITIONING The DS4600A scanner is able to decode moving barcode labels at a variety of angles, however significant angular distortion may degrade reading performance. When mounting the DS4600A take into consideration these three ideal label position angles: Pitch 0°, Skew 15° to 30° and Tilt 0°. Follow the suggestions below for the best orientation: The Pitch angle is represented by the value P in Figure 19. Position the reader in order to minimize the Pitch angle.
INSTALLATION 2 The Tilt angle is represented by the value T in Figure 21. Position the reader in order to minimize the Tilt angle. T Figure 21 - Tilt Angle 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.
DS4600A 2 2.6.1 Point-to-Point In this layout the data is transmitted to the Host on the main serial interface. Host Mode programming can be accomplished either through the main interface or the auxiliary interface. In Local Echo communication mode, data is transmitted on the RS232 auxiliary interface independently from the main interface selection. When On-Line Operating mode is used, the scanner is activated by an External Trigger (photoelectric sensor) when the object enters its reading zone.
INSTALLATION 2.6.2 2 Pass Through Pass through mode allows two or more devices to be connected to a single external serial interface. Each DS4600A 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.
DS4600A 2 2.6.3 RS232 Master/Slave The RS232 master/slave connection is used to collect data from several scanners to build either a multi-point 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 DS4600A transmits the messages received by the auxiliary interface onto the main interface. All messages will be passed through this chain to the master.
INSTALLATION 2.6.4 2 RS485 Master/Slave The RS485 master/slave connection is used to collect data from several scanners to build a multi-point 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.
DS4600A 2 2.6.5 Multiplexer Each scanner is connected to a Multiplexer (for example MX4000) with the RS485 half duplex main interface.
READING FEATURES 3 3.1 3 READING FEATURES 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 27. Laser Beam Figure 27 - 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.
DS4600A 3 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 29.
READING FEATURES 3.2 3 DECODING CAPACITY IN LINEAR MODE When in Linear Reading mode, the number of reads performed by the DS4600A 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.
DS4600A 3 If scanning is perpendicular to the direction of the code movement (Figure 31), the number of effective scans performed by the reader is given by the following formula: SN = [(LH/LS) * SS] - 2 These symbols signify: SN = number of effective scans LH = label height (in mm) LS = label movement speed (in mm/s) SS = number of scans per second For example, the DS4600A (800 scans/sec.), for a 25 mm high code moving at 1250 mm/s performs: [(25/1250) * 800] - 2 = 14 effective scans. 3.2.
READING FEATURES 3 If scanning is parallel to the code movement (Figure 32) the number of effective scans is given by: SN = [((FW-LW)/LS) * SS] - 2 These symbols signify: SN = number of effective scans FW = reading field width (in mm) LW = label width (in mm) LS = label movement speed (in mm/s) SS = scans per second For example, for a 100 mm wide code moving in a point where the reading field is 200 mm wide at a 2000 mm/s speed, the DS4600A (800 scans per sec.
DS4600A 3 The reading characteristics for the raster versions are given in the table below. The distance between the top and bottom scan lines is given at different reading distances measured from the laser beam output window.
