GENERAL FEATURES 1 1.1 1 GENERAL FEATURES INTRODUCTION The DS4600A is a compact laser scanner complete with decoder designed and produced to be a flexible and affordable solution for all medium range materials handling applications. Standard Application Program A Standard Application Program is factory-loaded onto the DS4600A. This program controls barcode reading, serial port interfacing, data formatting and many other operating and control parameters.
DS4600A 1 1.
GENERAL FEATURES 1 Electrical connection is provided through a cable on the side of the reader; this cable is terminated with a 25-pin connector (see Figure A, 1). The laser beam output window is on the right hand side of the scanner (Figure A, 2). 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.

DS4600A 2 2.3.3 Auxiliary RS232 Interface The auxiliary serial interface is used exclusively for RS232 point-to-point connections. The parameters relative to the auxiliary interface (baud rate, data bits, etc.) as well as particular communication modes such as Local Echo can be defined using the WinHost utility program or Host Mode programming. For more details refer to paragraph 2.5 and to the section "Auxiliary Interface Menu" in the WinHost Help On Line.
INSTALLATION 2.3.4 2 Inputs There is an input available on the DS4600A scanner relative to the External Trigger. There are also 2 general purpose inputs: IN1 can be used to store the code verifier (see "Store verifier HW" in the WinHost Help On Line). IN2 can be used as the Reading Field Control signal which determines either the Code Reading Condition or the Code Resolution parameter for each reading phase. Refer to the WinHost Help On Line.

INSTALLATION 2 The electrical features of the inputs are: Maximum voltage = 30 Vdc Maximum current = 25 mA. An anti-disturbance hardware filter is implemented on the External Trigger input (< 5 milliseconds delay). An additional 15 ms (typical) delay can be implemented through a dedicated software parameter (refer to WinHost Help On Line). 2.3.
DS4600A 2 2.4 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 18. Position the reader in order to minimize the Pitch angle.
INSTALLATION 2 The Tilt angle is represented by the value T in Figure 20. Position the reader in order to minimize the Tilt angle. T Figure 20 - Tilt Angle 2.5 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 2.5.1 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. The possible main interface types for the scanner are RS232 or RS485 Full-Duplex. (20 mA C.L. can also be used if the INT-24 accessory is installed). In Local Echo communication mode, data is transmitted on the RS232 auxiliary interface independently from the main interface selection.
INSTALLATION 2.5.2 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 2.5.3 RS232 Master/Slave The RS232 master/slave connection is used to collect data from several scanners to build a multi-sided reading system; there can be one master and up to 9 slaves connected together. The slave scanners are connected to 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 2.5.4 2 RS485 Master/Slave The RS485 master/slave connection is used to collect data from several scanners to build 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 2.5.5 Multiplexer Each scanner is connected to an MX4000 with the RS485 half duplex mode on the main interface.

DS4600A 3 3 3.1 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 26. Laser Beam Figure 26 - 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.
READING FEATURES 3.1.1 3 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 28.
DS4600A 3 3.2 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.
READING FEATURES 3 If scanning is perpendicular to the direction of the code movement (Figure 30), 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.
DS4600A 3 If scanning is parallel to the code movement (Figure 31) 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.
READING FEATURES 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.
