Christie CineLife+ CP4415-RGB User Manual page 31

For example, to set red to 73.86%, green to 84.55%, and blue to 60.41%, the command
would be (RGB+MODE 1 7386 8455 6041).
14. Allow 20 minutes for the laser devices to stabilize at the new values.
15. To ensure the required color point has not drifted, measure the color points with the
spectroradiometer.
It may be necessary to make minor adjustments to RGB drives to get back to the required
color point. If necessary, make the adjustments using the (RGB+MODE 1 IR IG IB) command
in Kore Librarian. A wait period is not required after making minor adjustments.
16. In row 9 of the LiteLOC Sensor-to-screen Calibration workbook, enter the current settings for
red, blue, and green.
The drive percentages in columns A, B, C of rows 15 to 23 are calculated based on the current
settings. The example values in the workbook are red=73.86%, green=84.55%, and
blue=60.41%.
17. To set the laser drive levels for row 15 of the workbook, run the command from row 15 column
K (RGB+MODE 1 IR IG IB) in Kore Librarian.
For example, (RGB+MODE 1 6386 7455 5041)
18. Perform the measurement using the spectroradiometer and record the returned values for x, y,
and fL in columns G, H, and I of row 15 of the workbook.
For example, x=0.3334, y=.2885, and fL=510.
19. To obtain the color sensor values for the first set of drive percentage values in row 15, run the
command from column N, row 24 (RGB+MEAS?) in Kore Librarian.
The example response is shown below:
(RGB+MEAS!"3073532" 007 "2564292" 007 "1265818" 007 09497 07874 00000 10000 "1,
02863,03597,00000,02799, 02863,03597,00000,02799")
where SX=3073532, SY=2564292, and SZ=1265818
20. Record the returned values for SX, SY, and SZ in columns D, E, and F of row 15 of the
workbook.
For example, SX=3073532, SY=2564292, and SZ=1265818
21. Repeat steps 16 to 19 for rows 16 to 23.
22. From row 28 of the workbook, copy the highlighted command and run it in Kore Librarian.
For example, copy (RGB+CAL2 "5137" "610" "345" "0" "534" "4490" "34" "0" "-167"
"57" "1640" "0" "-125503" "-133936" "-57954" "1" "637" 1 0) to Kore Librarian and
run the command.
LiteLOC calibration is complete.
23. Power off and restart the projector.
The LiteLOC calibration takes effect.
24. Log into the projector with the Service account.
25. From the display panel, select Laser Settings > Laser Power/LiteLOC Setup.
Controls to set the required brightness and x,y controls are now available.
