Christie D4K40-RGB Replacement Instructions Manual page 14

• Maximum Expected Room temperature: 35 degrees Celsius
• Red power level: 78.3%
• Green power level: 63.2%
• Blue power level: 66.4%
7. Wait 15 minutes for the laser devices to acclimatize to the new values.
8. 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.
• For CP43XX-RGB series projectors, the DCI white point is x=0.314, y=0.351.
• For 4K40-RGB series projectors, the D65 white point is x=0.313, y=0.329.
Wait a few minutes for the lasers to stabilize and ensure that the white point is not shifting
between measurements.
9. Re-establish the connection to the photon controller using NetTerminal or Kore 10-bit Librarian,
on port 5103.
10. Send the command (RGB + MEAS?) to the photon controller.
The current color sense X, Y and Z values are returned, showing the temperature of the
different devices. For example:
• Red: Color sense X value
• Green: Color sense y value
• Blue: Color sense Z value
• Purple: Red devices temperature * 100
• Brown: Blue devices temperature * 100
11. Enter the returned values into line 27 and line 63 of the spreadsheet.
The temperature values reported in NetTerminal must be divided by 100 before being entered
on line 27 and Line 63.
12. Use Kore Librarian to connect to the projector on port number 5000.
13. Login to the projector with Service access.
14. Switch to the Scripting tab.
15. To lower the fan speed and increases the internal temperature of the laser devices, use the
script for the upgraded projector.
Lowering the fan speed allows for another set of Csense measurements to be collected at a
higher temperature without actually changing the room temperature.
• CP43XX-RGB series projectors
Kore Librarian must be used as NetTerminal is not capable of sending a script.
