  • Page 9: Packing Panels In The Flightcase

    To ensure that LC 1140/2140 panels can withstand the shocks that normally occur during transport, they must be packed in a Martin flightcase and transported in an upright position as described in this section. Damage caused to panels that are incorrectly packed or exposed to abnormal shocks is not covered by the product warranty.

  • Page 10: Physical Installation

    Physical installation Warning!Use two clamps attached to conical couplers to rig each panel. Secure with two approved safety cables, looping one cable around each vertical side column. Do not use the LED tubes as secondary attachment points. Hang a maximum of seven attached panels vertically. If a curtain more than seven panels high is required, a new curtain must be hung from another supporting structure.

    For example, to display a full 1024 x 768 video image on an installation 200 pixels (8 panels) wide and 150 pixels (6 x LC 1140 panels or 3 x LC 2140 panels) high, you must ‘shrink’...

  • Page 19 Both types of panel are addressed starting with y = 0, but: • setting the y coordinate to zero maps an LC 2140 panel to the top row (if you set DIP switch pins 7 - 12 to 0, the panel displays the rows with y coordinates 0 and 1), and •...
  • Page 20 Here is an example of how to set an array of panels so that each panel displays the correct tile in the video image. Let us say that: • You have installed twenty-four LC 2140 panels in a curtain eight panels wide and three panels high, giving you 200 x 150 pixels in your installation.
  • Page 21 See Figure 16. To address the LC 2140 panels in your installation so that they display the 200 x 150 pixel block in the center of your monitor, you must give them the x and y coordinates shown in the illustration.
  • Page 22 If LC 1140 panels are used to display the same pixels from the video image, they must be set as shown in Figure 17. Note that with LC 1140 panels, you must set the y coordinate to the number of the row on the y axis minus one (i.e.

    • If you are mixing LC 2140 and LC 1140 panels in an installation, bear in mind that LC 1140 panels cannot be set to display the top row (row with y coordinate zero) in the video image – this row can only be displayed with LC 2140 panels.

It is Martin policy to use the best quality materials available to ensure optimum performance and the longest possible component lifetimes. However, optical components in all lighting fixtures are subject to wear and tear over the life of the fixture, resulting in gradual changes in color rendition, for example.

    Important! The PCBs are sensitive to ESD (electrostatic discharge). Take precautions to avoid ESD damage. Avoid touching electronic components. LC 1140 and LC 2140 panels are protected by three 5 amp slow-blow fuses on the three power supplies in the panel base.
