    USB cable. The LSS-100P should be mounted on the rear wall of the auditorium. It is aimed towards the center of the screen using the internal LEDs. Before the first show or after the last show, a test pattern is projected and pink noise sent to each speaker.

    Installation It is a lot easier to do the initial testing of the LSS-100P on a table or the floor of the projection booth instead of on top of a ladder. 1. Connect an Ethernet cable between the OUT connector of the supplied POE Power Injector and the LSS-100P.
  • Page 9 The source of that information is set by the first column of the light table. You can select U.S. or metric units for temperature and luminance. LSS-100P units with board revision F or higher also measure the relative IR illumination of the screen. This is useful for detecting issues with IR audio and captioning systems.
  • Page 10 Up to 14 SPL reference columns may be defined. 9. The LSS-100P determines the highest SPL it measured from midnight local time to midnight local time. The highest value is logged each night at midnight. You can set a limit for the maximum SPL on this page.
  • Page 11 OrgKey, Theater Number, and Screen Number. The “Distance of LSS-100P to Screen” field is used when running the audio/video sync check (coming soon). Additional information about the auditorium can be entered in the Comments field. These comments show up on the home page and are reported in the XML web services log data.
  • Page 12 Config” button to save the settings. Note that the new IP address takes effect immediately. The laptop will attempt to connect to the LSS-100P at the new IP address. The laptop network configuration may need to be changed to reach the LSS-100P at the new IP address.
  • Page 13 LSS-100P. 20. Note that the bottom line of this page shows the last time the LSS-100P clock was updated from the NTP server. Since the LSS-100P does not have access to an NTP server when it is only connected to your laptop, this will indicate that the last update was never.

    4. Turn the LSS-100P LED switch to on and adjust the focus control until the red spots on the screen appear to be in focus. As the LSS-100P is adjusted out of focus, the hole in the middle of the spots fills in. When the LSS-100P is in focus, the hole in the center will be open and the edges sharp as shown in Figure 12.

  • Page 15: Ntp, Ir, And Luminance Check

    NTP, IR, and Luminance Check 1. Go back to the NTP configuration page (shown in figure 8) and ensure that the LSS-100P has received an NTP update. 2. If desired, the LSS-100P luminance measurement can be scaled to agree with a reference meter.
  • Page 16 The LSS-100P can only post to one server at a time. A suggested wait command is “lss100.sys.script_wait|120”. The LSS-100P logs a hash of the URL on a successful log post.

  • Page 17: Script Test Run

    Data Analysis The LSS-100P presents the captured data in a log (as shown in figure 2) and a graph (as shown in figure 3). Out of limit operation is easily identified in the log by a value being printed in red. The graphs show the measured values along with limit lines allowing easy detection of trends and out of limit operation.

  • Page 19: Multiple Logs On One Page

    Figure 14 – Graph Generation from LSS-100P CSV Data Multiple Logs on One Page It may be desirable to have a single web page that includes the logs from multiple LSS-100P units (for example, all the auditoriums in a particular theater). This can be accomplished using HTML iframes (inline frames).

  • Page 20: Multiple Auditorium Summary

    Most of the iframe attributes are similar to the previous example. As noted before, the lack of an rn in the src attribute tells the LSS-100P to evaluate the last n records for an out of limit condition. In the examples above, a particular log link will be red if one of the last 20 records shows an out of limits condition.

    In some cases, there may be a tab character after the last response and before the carriage return. The command is not echoed by the LSS-100P. LSS-100P commands can be tested using Tera Term, RealTerm (both listed below), or telnet on operating systems that include it (Windows XP, Linux, Mac OS).

    15 1\r The example command tells a Lexicon QLi32 (located at 192.168.1.123, port 10001) to put pink noise on each speaker in sequence for 15 seconds (looping once). An LSS-100P script can capture the SPL of each of the speakers.

    A portion of a sample test script is shown below. A particular speaker is selected, the LSS-100P is given time for the SPL reading to stabilize, the reading captured, then the next speaker is selected.

    LSS−100P Installation & Operation Manual Log Post XML Format Sample XML data posted to a web server is shown below. Note that the web server must accept chunked data as defined in RFC 2616 section 3.6.1. Note that DateTime is a Unix time stamp (seconds since January 1, 1970 UTC).

  • Page 28: Lss-Db

    The web server can parse the XML to a database for further analysis and reporting. A simple PHP script that appends each new LSS-100P XML report to a file and mails each report is shown below. This is a good starting point to verify that things are working.
  • Page 29 Keeping the factory firmware as a backup allows you to go back to it should something go wrong. The Set Serial Number button is not normally used in the field. The MAC address of the LSS-100P is based on the serial number.

  • Page 30: Firmware Update

    (allowing another attempt at the update), hold down the restore button as power is applied to the LSS-100P. If the button is held for about 1 second before and 1 second after power is applied, the factory firmware will be reloaded and system configuration will remain unchanged. The green LED flashes as the firmware is reloaded.

  • Page 31: Useful Software

    The amount of days to look for out of tolerance conditions can be set on the main Configuration Page of each individual LSS-100P. Since it is able to display multiple devices on a single page it may be the easiest way to get an overview of an entire multiplex of LSS-100P’s.

  • Page 32: Lss Database Software

    Remote LSS-100P devices that have been installed in theaters will post the results of each test to a URL (Uniform Resource Locator) where the LSS-DB collects the data. The LSS Database provides a mechanism to collect the LSS-100P data and store it in a database.

  • Page 33: Appendix A - Red/Green Flash Script Start

    (send TCP string or provide contact closure) to start a script. The LSS-100P compares the output of the red and green sensors. When the green to red ratio exceeds a threshold, the image is considered a binary 1. When the red to green ratio exceeds a threshold, the image is considered a binary 0.

  • Page 34: Appendix B - Usb Power Interface And Contact Closure Script Start

    1. If USB power or contact closure script triggering is being used, connect the supplied cable to the LSS-100P. Connect the other end of the cable to the USB adapter board. Refer to Figures 23 and 24 for wiring instructions. If contact closure script triggering is being used with Power Over Ethernet, the USB cable can be routed directly to the GPIO connections on the server.

  • Page 35: Appendix C - Language Support

    LSS−100P Installation & Operation Manual Appendix C – Language Support The primary language of the LSS-100P is English. User defined fields on the home page and in scripts may be in any language. The configuration fields accept UTF-8 coding, allowing text of almost any language to be directly keyed in or pasted in.
