b) Connect the laptop to the projector using Net Terminal or Kore Librarian, with port 5000.
c) Log in as the Service account.
d) To enable the communication to the photon controller, send the command (CAL+PASS 1).
2. Connect the laptop to the photon controller using Net Terminal or Kore Librarian, with port
5103.
3. Turn off the laser and close the shutter.
4. To start the DAC calibration, send the following command: (ENG+CALB 0 0).
This process takes approximately one minute. DAC calibration is only required after replacing
the color sensor board.
5. To complete the calibration, reboot the projector.
Performing the LiteLOC v1 calibration
Due to the manufacturing tolerance of the color sensor board and the LOS system, calibrate the
LiteLOC v1 response to the light intensity as the temperature of the laser devices changes.
1. Contact Christie Technical Support for a copy of the Horizon Factory Calibration Procedure
spreadsheet.
2. On the projector, display a framing test pattern.
3. Setup the color meter in the same manner as used for creating laser and MCGD files.
4. Login to the projector with Installer access or higher.
5. Navigate to the laser power settings page.
6. Set the following values:
•
LiteLOC is disabled
•
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 an applicable 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.
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
