How to Calibrate an M2 or M3 controlled display with M2Config Utility.

Question

  • How can I calibrate and M2 or M3 controlled display utilizing M2Config utility?

Environment

  • Product Family: Message Displays
  • Product: AF-3400 RGB, AF-3500 RGB, AF-3550 RGB, AF-3700 RGB
  • Components: M2 Controller, M3 Controller
  • Control System: M2Config

Answer/Steps

Manual Calibration Process

To complete a Manual Calibration we need an individual on site.
  1. Connect to the controller using TCP/IP.
    • Note: The control computer can be used.
    • Note: Calibration function needs to be enabled in M2Config utility. By default it is disabled.
      • Select the Edit tab.
      • Select Preferences.
      • Select Status tab.
      • Check the box for "Show Calibration Tab"
  2. It is best to start with a memory defrag.
  3. Once memory cleanup is completed, select the calibration tab in M2Config.
    • Note: Allow it to load completely before calibration. This would be from a previously stored calibration.
      • Most times this will error out with M2 or M3 controlled displays
  4. Ensure that the technician on site is at least 50-100 yards away from the display and facing it straight on.
  5. Verify that the "Automatically set restore points" check box is selected. Refer to Figure 1. Relative calibration (setting restore points) ensures that previous calibrations are not overwritten or lost.

  6. To calibrate an individual module, ensure the height and width drop down boxes match the module dimensions.
    • Check display BOM to determine module dimensions.
  7. Set the sign to red by clicking the red button in M2Config. Refer to Figure 1.
  8. If the tech on site finds modules on red that are either brighter or darker than the rest of the sign use the arrows to navigate to the module in question.
  9. To make an individual module brighter on red, adjust the red slide bar to the right (positive numbers). To make an individual module dimmer on red adjust the red slide bar to the left (negative numbers).
  10. After selecting an adjustment, click the Calibrate button to make this change. You may need to make several changes on each mod to ensure the color matches correctly. Relative calibration causes each adjustment to stack on top of each other so if you adjust the module -5 on the first try and +3 on the second try the net result in an adjustment of -2. Refer to Figure 1.
  11. Click Save Calibration to save calibration changes. It is important to save the calibration because a display reset will remove any unsaved changes. It is a good idea to save periodically but is not necessary after every module. It may be necessary to power cycle the display to see effective changes.
  12. Continue calibrating red until all modules are calibrated.
  13. Repeat Steps 6 - 11 for green and blue.
  14. Once all three colors and have been calibrated, set the board to white to see if any modules are still out of calibration.
    • Note: If the modules match on all three colors they should match on white. If they do not look good on white a compromise may need to be made to get the modules to look good on the three colors and white.
  15. Save the calibration file once all adjustments have been made.
  16. Verify the calibration file did in fact save by navigating to the File Transfer tab.
    1. Click on the open folder button in upper right next to the IP of the controller.
    2. Select the Face 0 or Face 1 subfolder.
    3. Check the modification date/time on the INTENSITY.BIN file (should be current if the date and time are correct in M2Config)
  17. Resume playing regular content, once the calibration is complete by clicking on none button in the calibration tab.
