16. To execute the script, click the red arrow.
A confirmation the command has been executed is displayed, and the projector noise level
goes down.
17. In the projector software, set the following values:
• Display White Test Pattern is enabled
• LiteLOC is disabled
• Maximum Expected Room Temperature: 35 degrees Celsius
• Red power level: 78.3%
• Green power level: 66.3%
• Blue power level: 70%
18. Wait 15 minutes for the laser devices to acclimatize to the new values.
19. Re-establish the connection to the photon controller using NetTerminal or Kore Librarian, on
port 5103.
20. Send the command (RGB + MEAS?) to the photon controller.
21. Compare the new blue temperature to the original value.
If the difference is less than eight degrees wait for a few more minutes and take another
reading until the blue temperature is at least eight degrees higher than the original reading.
You may need to modify the actual room temperature to achieve the target blue temperature.
22. Adjust the blue and green power levels to achieve a DCI white point, as measured by the color
meter. Do not adjust the red value.
23. Send the command (RGB + MEAS?) to the photon controller.
The system retrieves the color sensor X, Y and Z values, and the blue and red devices
temperatures.
24. Verify line 63 of the spreadsheet has the values identified in step 10.
25. Enter the values returned in step 23 into line 64 of the spreadsheet.
The spreadsheet automatically calculates the calibration data and populates line 96 on the
calculator.
The temperature values reported in NetTerminal must be divided by 100 before being entered
on line 27 and Line 63.
26. Type the command on line 96 of the spreadsheet into NetTerminal or Kore Librarian and send it
to the photon controller.
The calibration data is saved to the color sensor board.
27. (CP43XX-RGB series projectors only) Close the LOS port.
The port must be closed.
a) To close the direct communication to Photon, connect the laptop to the projector using
NetTerminal or Kore Librarian, with port 5000, and send the following command: (CAL
+PASS 0)
b) To verify the port is closed, connect to port 5103 and send the following command: (SST?)
If a response is returned, the port is open and must be closed.
