DS1500 2 2.2.
INSTALLATION 2.3 2 ELECTRICAL CONNECTIONS All DS1500 models are equipped with a cable terminated by a 15-pin male D-sub high-density connector for connection to the power supply and input/output signals. The details of the connector pins are indicated in the following table. 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.
DS1500 2 2.3.1 Power Supply Power can be supplied to the scanner through the pins provided on the 15-pin connector used for communication with the host (Figure 6): DS1500 VS USER INTERFACE 1 V+ (5 Vdc) 8 GND 5 Earth Ground GND Figure 6 - Power Supply Connections The power must be 5 Vdc only. It is recommended to connect pin 8 (Protective Earth Ground) to a common earth ground. GND is internally connected to the chassis. NOTE 2.3.
INSTALLATION 2 RS232 Interface The serial interface is used in this case for point-to-point connections; it handles communication with the host computer and allows both transmission of code data and the programming of the scanner. This is the default setting. The following pins are used for RS232 interface connection: Pin 2 3 4 Name TX232 RX232 SGND Function transmit data receive data signal ground It is always advisable to use shielded cables.
DS1500 2 RS485 Full-Duplex Interface The RS485 full-duplex (5 wires + shield) interface is used for non-polled communication protocols in point-to-point connections over longer distances (max 1200 m / 3940 ft) than those acceptable for RS232 communications or in electrically noisy environments.
INSTALLATION 2 RS485 Half-Duplex Interface The RS485 half-duplex (3 wires + shield) interface is used for polled communication protocols. It can be used for Multidrop connections with a Datalogic Multiplexer, (see par. 2.6.3 and 2.6.4) exploiting a proprietary protocol based on polled mode called MUX32 protocol, where a master device polls slave devices to collect data.
DS1500 2 Figure 10 shows a multidrop configuration with DS1500 scanners connected to a Multiplexer. To avoid any possible Ground loop, keep the chassis isolated from the Ground. CAUTION This is an example of multidrop wiring. Consult the multiplexer manual for complete wiring instructions.
INSTALLATION 2.3.3 2 Auxiliary RS232 Interface The auxiliary serial interface is used exclusively for RS232 point-to-point connections. The parameters relative to the aux 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".
DS1500 2 Code Verifier If the DS1500 is used as a Code Verifier, it is possible to indicate to the scanner what code to store as the verifier code through the WinHost program, (refer to the WinHost Help On Line). 2.3.
INSTALLATION 2 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). 2.3.5 Outputs Two general purpose outputs are available. These outputs can only be connected as open collector configurations.
DS1500 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 DS1500 scanner is able to decode moving barcode labels at a variety of angles, however significant angular distortion may degrade reading performance. When mounting the DS1500 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 15. Position the reader in order to minimize the Pitch angle.
DS1500 2 The Tilt angle is represented by the value T in Figure 17. Position the reader in order to minimize the Tilt angle. T Figure 17 - Tilt Angle By using the ACB (Advanced Code Builder) software parameter, the tilt angle is less critical and can be decoded even if the scan line doesn’t cross the entire code. See par. 3.1 or the Help On Line for details.
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.
DS1500 2 In this layout the data is transmitted to the Host on the main serial interface. Host Mode programming can be accomplished through the main interface. 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 DS1500 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.
DS1500 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 DS1500 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 Multiplexer Layout Each scanner is connected to a Multiplexer (for example MX4000) with the RS485 half-duplex main interface. 2 2 2 1 31 1 0 Host 1 Main Interface 2 External Trigger (for On-Line mode) MX4000 Figure 22 - Multiplexer Layout When On-Line Operating mode is used, the scanner is activated by an External Trigger (photoelectric sensor) when the object enters its reading zone.
DS1500 3 3 3.1 READING FEATURES ADVANCED CODE BUILDER (ACB) In addition to linear reading, the Advanced Code Builder (ACB) allows code reading by “stitching” together two partial reads of it. ACB is not as powerful as Advanced Code Reconstruction due to limits on tilt angle, speed and Multi-label function; but it is effective in the case of close-to-linear, small height codes, damaged codes, or poor print quality codes.
READING FEATURES 3 ACB Readable ACB is disabled by default but can be enabled for the following code types: • • • 3.1.1 Code 25 Interleaved Code 39 Family Codabar • • • Code 128/EAN128 EAN/UPC (without ADD-Ons) Code 93 Important ACB Reading Conditions • Do not use ACB for omni-directional reading stations. • ACB can be activated for each symbology independently from the others. • ACB requires that the code be in movement with respect to the scanner.
DS1500 3 3.1.2 Tilt Angle Improvement with ACB ACB allows barcode reading with an increased tilt angle. The tilt angle depends upon the code aspect ratio defined as H/L according to the table below: L H Aspect Ratio H/L 0.33 0.25 0.125 3.
READING FEATURES 3.2.1 3 Step-Ladder Mode If scanning is perpendicular to the code motion direction (Figure 23), the number of effective scans performed by the reader is given by the following formula: SN = [(LH/LS) * SS] – 2 Where: SN = number of effective scans LH = label height (in mm) LS = label movement speed in (mm/s) SS = number of scans per second Direction of code movement at LS speed LH DS1500 Laser beam Figure 23 - "Step-Ladder" Scanning Mode For example, the DS1500 (1200 scans/sec.
