  1. p by step procedure demonstrating how to use the PDF comparator in the LVS75xx application.

    Overview

    •  The comparison of the LVS-7510 golden to the Master PDF file happens only at setup.
    • ScanProof compares the .BMP version of the LVS-75XX golden image created from the label during the AutoSetup process to a PDF Master artwork file selected by the user.
    • This comparison happens on only one image; the golden image taken during setup. After the comparison in ScanProof, the LVS golden image is compared to the image of every label printed.


    Operation

     From the Blemish setup screen of the LVS-75XX software, the Correlate Artwork button launches the ScanProof application.

    • The LVS-7510 application goes dormant while ScanProof is performing the comparison. The ScanProof application produces a comparison report and passes it back to the LVS-7510.
    • When the ScanProof application terminates, the LVS-7510 returns to the Blemish Setup screen.
    •  A report from the ScanProof application is passed to the LVS-7510.

    •       If the report is marked Fail, the LVS-7510 software notifies the user of a failed report.

    •       If the report is marked Pass, the LVS-7510 allows the user to complete the Blemish setup.

    Before you start….

    • Depending on the hardware configuration, please make sure you have the following versions installed in your LVS-75XX PC.
    •      LVS-75XX Internal
      • ???
    •       LVS-75XX External
      •  5.6.7.415 & above
    • Copy the Microscan.ini to the following path:

  • Summary

     
    Tests were run using an ID-20 and a Raspberry Pi3 SBC running Raspbian to determine to what extent the ID-20 is compatible with this hardware / software combination. It was found that, if the ID-20 has a static IP address, then WebLink and Telnet can both be used to talk to the reader.
    However, the virtual com port cannot be accessed from Linux

    Initial Network Configuration

     
    1.     Starting with a clean Raspbian operating system. Set up your wifi or wired network for internet access if required.
     
    2.     Go to network icon in top-right of menu bar and right-click on it.
    User-added image
     
    3.        You'll see two network adapters listed if you click on the interface drop-down – wlan0 and eth0
    User-added image
     
     
    Now plug in your ID-20 (configured for static IP address)
    ifconfig from terminal will show additional adaptor eth1.
     
    There is no graphical tool for configuration ethernet interfaces. Instead, you have to edit
    /etc/network/interfaces. You can do this as follows:
     
    1. Open a terminal window
    2. Navigate to the correct directory ( cd /etc/network )
    3. make a copy of the interfaces file ( sudo cp interfaces oldinterfaces ) Open interfaces file with nano ( sudo nano interfaces )
    4. scroll down to end of file and type in the following

    allow-hotplug eth1
    iface eth1 inet static

    address 192.168.188.1
    netmask 255.255.255.248
    gateway 0.0.0.0
     
    1. Once you've typed that in, Control-O and Enter to save and Control-X to exit.


     To check that it worked you can type in “more interfaces” to see the contents of the interfaces file.

    Now unplug the camera and plug it in again. You can see the network settings by using the ifconfig command in the terminal window.

    At this point you can open Chromium (web browser) and navigate to the address of your camera to bring up WebLink just as you can on a Windows PC.
     

    Testing with WebLink through browser.

     
    WebLink works exactly the same on Linux as it does on Windows.
     

    Testing with Telnet from command line

     
    Note that telnet is not installed by default on Raspbian. sudo apt-get install telnet to do this. Problems were encountred accessing mirror servers for packages, unplugging the MicroHAWK from Raspberry Pi appeared to help solve these issues. This suggests that the software was trying to use the wrong network adapter to access the servers.
    Once telnet was installed it worked just as it does on Windows.

    Remote triggering from another PC.

     
    Set up SSH on Raspberry Pi. You enable this by going to the Pi menu - Preferences - Raspberry Pi Configuration - Interfaces. You should probably change the default password for security here and the Pi will nag you if you don't.
    Connect to Raspberry Pi SSH from PC using program like PuTTY. Port number for SSH is 22. You can then enter commands just as you would if you were running on the Pi directly.
     
     

    Adding Additional Cameras

     
    Adding additional cameras requires adding additional information to the /etc/network/interfaces file. Here's a screenshot showing two ID-20 MicroHAWK cameras connected to Raspberry Pi.
    User-added image

     
    Tests have not yet been run to ensure that multiple cameras enumerate in the same order every time the Pi is powered up.
     

    Using Dynamic IP Addressing

     
    At this point in time it has not been proved possible to connect Raspbian to an ID-20 set to DHCP. Tests were run with both static and DHCP (APIPA) on the Pi.
     
     

    Using VCOM to communicate with ID-20

     
    VCOM does not work on the Pi3 / Raspbian (or any other version of Linux tested). The cause for this is believed to be the lack of support for composite USB devices in Linux.
     
    Looking on the web, it appears that there are a number of devices that have the same problem on Linux and that these have been hard-coded into one of the linux driver files (/drivers/usb/class/cdc-acm.c). This is unlikely to happen for the MicroHAWK.
    Apparently the workaround is to mark the device (in the file above) with "NO_UNION_NORMAL" which means that the device has no union descriptor.
     

    Appendix A : Configuring the ID-20 to use a static IP address

     
    The ID-20 needs to be configured to use a static IP address before using it with Raspbian. The easiest way to do this is to connect the reader to a PC and then open a web browser to connect using WebLink.
     
    Once you have WebLink open (default address is 192.168.188.2), go to the gear wheel icon in the upper right, click on it and then click on the Advanced icon.

    This will open the configuration pages as shown below. Select Communications.
    User-added image

    Click on DHCP and change it to Static. If the camera address also needs changing then do that here too.
    User-added image
     
    Close the Advanced Settings box and save the camera settings to flash memory using the icon in the upper right indicating a reader on top of a floppy disk.
    User-added image
     
    The ID-20 is now ready to connect to Linux.

  • Most mid and high range label design software allows for re-scaling of print templates for different dpi of printers.  In that case a customer who has designed print templates for a 203 dpi printer and would like to purchase a LVS-7510 with 300 dpi printer can easily adjust their print templates for use with the LVS-7510 system.  For customers using label design software that does not provide this easy re-scaling, it would be required to create new print templates.  A 203 dpi version of the ZT600 series will be supported by LVS-7510 in 2018.  However, it is recommended that only barcodes with x-dimensions of 15 mil or larger be used with that resolution printer to help minimize the likelihood of a defect in the print head leading to a barcode fault.

  • In some cases, the USB license dongle will lose the Visionscape licensed features (Standard GigE, Intellifind, TPC, DIVS).  The reason for this is that each time Visionscape reads the license key, information is written back to the dongle.  Non-volatile EEPROM memory  eventually fails after some finite number of writes, effectively corrupting the key.  This has been fixed in a run-time update to the USB key that allows the key to save license information on the computer instead of the dongle.  

    This runtime has been include in newer versions of the software.  

    Dongles that have lost their licenses will need to be replaced.  Contact Microscan for replacement options.

    To prevent dongle failure, update the software to the latest versions.  This software can be found on the Microscan website.  Contact Microscan for updates to specific solutions.

  • How to update the QX-hawk firmware when the unit does not respond to the normal auto connect. 1. Start the QX-Hawk in Safe mode. To do this , power the unit while keeping the Default pin (3) connected to the ground pin (7). In the standard QX cables, these are the green and blue wires. Keep the connection until the red cross comes on or for about 15 seconds. 2. Start ESP and force connect with communication settings 115,N,8,1. 3. Go to the ESP terminal. 4. Type and see if there is an answer. The unit should respond with the firmware versions and the text SAFE MODE. 5. Try to update the APP code which has been working before. The update can take more than 10 minutes. After the update, re-power the QX-Hawk. * If the update has succeeded, try to connect via Ethernet and update to the new Kernel, App code and the DSP code. In this order. * If the update has not succeeded, Force connect via RS-232 and update to the new Kernel, App code and the DSP code.

  • Before executing the attached WSF File (Windows Script File), you must:
    - Certify that Telnet Client is enabled on Windows. For more information, please check the article "Enabling Telnet Client on Windows."
    - Copy the upgrade licenses for the unit to: C:\Microscan\Vscape\Licensing.  (You may only have the license for one unit at a time.)
    - Certify that you have a fresh AutoVISION 4 installation, i.e., just one VSF file available on C:\Microscan\Vscape\Firmware.
    - Certify that you have correct boot version on the unit.

  • Over the years, operational requirements of GS1 System users have influenced the dimensional specifications of GS1 System symbols, and these dimensional specifications have in turn influenced the development of scanning system optics and printing processes. The dimensional requirements for each application area defined in Section 2 of General Specifications are set out in the GS1 System Symbol Specification Tables (SSTs).

    In the previous version of software, there was greater symmetry in the chosen aperture.  With version 15, there have been changes to the required aperture for EAN/UPC-A (Table 2 now requires a 10 mil aperture where previously it was 6 mil), GS1 Data Matrix (previously the aperture was 80% of the cell size whereas now there are fixed apertures depending on the table), as well as others.  

    Each SST provides the following barcode specification detail:

    • The barcode(s) specified by the GS1 System for each application area.
    • The minimum, target, and maximum X-dimension (narrow element width) for the symbol, based on the scanning environment.
    • The minimum and target barcode height, based on the scanning environment.
    • The Quiet Zone width and, for primary and secondary symbols, the minimum and maximum separation between the two symbols (these measurements are expressed as multiples of the X-dimension in the form nX).
    • The minimum ISO quality specification expressed as g.g/aa/www, where g.g is the minimum overall symbol grade to one decimal place (on a 4.0 scale), aa is the effective measuring aperture in thousandths of an inch, and www is the wavelength of the light source in nanometers.

    The benefit of having to choose the SST means the verifier can now check X-dimension and symbol height to the specified application where before choosing a SST was required we could not.

    Table Selections are determined by Customer selection based upon the product that is being labeled.

    If the labeler selects a table, the symbology being used should follow the specifications in the table selected. EX: If Table 6 is selected for Regulated Healthcare Non-Retail not used in General Distribution, and the labeler has selected to use a 2D GS1 Data Matrix symbol, the symbol should follow the specifications in the table for minimum and maximum X-dimension requirements, symbol height requirements, quiet zone requirements and minimum quality specifications.

  • Every symbol decoded will run through the database. - If the symbol is in the database, it is a Match. - If the symbol is not in the database, it is a Mismatch. At the end of the read cycle, there is only ONE result, which will be (in the order of priority): - If ANY symbols are not decoded (the number of symbols required is set in the Multisymbol option, under Read Cycle), the read cycle result is Noread. - If ANY symbols do not match the database, the result is Mismatch. - If ALL symbols are decoded, and they are in the database, the result is Match. Each of the three outputs can be programmed for one of these events, and in some cases, a combination of these events. Also note that in most readers, when Matchcode is enabled, there is no more ‘good read’. Settings that say ‘Good Read’ now mean ‘Match’.
