Preparations

1. Perform these adjustments after the white balance

adjustment described in Section 4-5.

2. Make a col o r uniformi t y adjustm e n t fo r the

following four tones.

MIN tone (approx. 10% input signal)

MID-L tone (approx. 21% input signal)

MID-H tone (approx. 50% input signal)

MAX tone (approx. 75% input signal)

3. Place the cursor on the tone to be adjusted in the

Adjust menu and press the [ ] key. This displays

the Adjust Tone menu at the bottom of the screen.

Select the major adjustment lattice point No. and

color, and then adjust them.

4. The major adjustment lattice point numbers (a total

of 17 points) corresponds to the major adjustment

lattice point positions in the diagram on the right.

The color uniformity of the entire screen can be

adjusted by adjusting the white balance for each of

the points starting in order from the low numbers.

5. Adjustment point No.1 should not be adjusted,

because it controls the brightness of the entire

screen.

select the following two signals.

Solid monochrome adjustment color (use G color

adjustment when a color differential meter is

used).

Soli d white (use for adj ustment oth er than

above).

8. Reset color-shading correction before adjustment.

When 4 tones and all colors are to be reset,

place the cursor on [C.UNIF.] in the Adjustment

menu, pr e s s the [RESET] key and se l ect

[DEFAULT].

When only 1 tone is to be reset, place the cursor

on the tone to be reset, press the [RESET] key

and select [DEFAULT].

Single tone and monochrome resets cannot be

performed.

Adjustment procedure 1

(when a color differential meter is used)

1. First adjust [MID-L] tone [G:].

2. Select adjustment point [No.2][G:].

When the background is not [G] monochrome,

press the [MENU SELECT] key on the Remote

con t rol t ra ns mitt e r to c hang e to s ol id [ G ]

monochrome.

3. Measure the illumination at adjustment points No.

2, No.3, No.10 and No.11.

The values should be:

No.2 = Y2 [lx] No.10 = Y10 [lx]

No.3 = Y3 [lx] No.11 = Y11 [lx]

4. No.2 and No.3 adjustment point have the average

of Y2 and Y3.

Y2 = ( Y2 + Y3 ) / 2 ± 2 [%]

Y3 = ( Y2 + Y3 ) / 2 ± 2 [%]

5. No.10 and No.1 1 adjustment point have the

average of Y10 and Y11.

Y10 = ( Y10 + Y11 ) / 2 ± 2 [%]

Y11 = ( Y10 + Y11 ) / 2 ± 2 [%]

6. Then adjust [MID-L] tone [R] and [B].

When the background is [G] monochrome, press

the [MENU SELECT] key on the Remote control

transmitter to change to solid white.

7. Measure the color coordinates of adjustment point

[No.1] and make a note of them.

Assume that they are x = x1, y = y1.

Note: When the CL-100 color and color difference

meter is us e d , the [ ](delta ) mo d e is

convenient. When adjustment point [No.1]

color coordinate has been selected, set the

slide switch on the side to [ ](delta) while

holding down the [F] button on the front

panel. The measurement shown after this

displays the deviation from measurement

point 1.

8. Measure the color coordinates of measurement

point [No.2] and adjust [No.2][R:] and [B:] so that

the coordinates are as follows.

x = x1 ± 0.005 , y = y1 ± 0.010

CP-X430W

9. Similarly, measure adjustment points [No.3] to

[No.17] and adjust their color coordinates starting

in order from the small number points.

This completes adjustments required for [MIN].

Note: Since excessive correction may lead to a

correction data overview dur ing internal

calculations, use the following values for

reference.

[No.2] to [No.5] ± 40 or less

[No.6] to [No.9] ± 50 or less

[No.10] to [No.13] ± 70 or less

[No.14] to [No.17] ± 120 or less

10. Then adjust [MIN] tone [G] so that the adjustment

data set three times as much as [MID-L] tone [G].

This completes [G] color adjustments.

11. Then adjust [MIN] tone [R] and [B].

Select [No.2] [B:] and press the [MENU SELECT]

key on the Remote control transmitter to change to

solid white.

12. Measure the color coordinates of adjustment point

[No.1] and make a note of them.

Assume that they are x = x1, y = y1.

13. N o w m ea s u r e th e c ol or co o r di na te s o f

measurement point [No.2] and adjust [No.2][R:]

and [B:] so that the coordinates are as follows.

x = x1 ± 0.005 , y = y1 ± 0.010 (Target)

x = x1 ± 0.020 , y = y1 ± 0.040

14. Similarly, measure adjustment points [No.3] to

[No.17] and adjust their color coordinates starting

in order from the small number points.

This completes [MIN] tone adjustments.

15. Now make similar adjustments for [MID-H] tone.

(Adjust [MID-H] tone [G] so that the adjustment

data set half as many as [MID-L] tone [G].)

16. Now make similar adjustments for [MAX] tone.

(Adjust [MAX] tone [G] so that the adjustment data

set half as many as [MID-L] tone [G].)

Adjustment procedure 2

(visual inspection)

1. First adjust [MIN] tone [G:].

2. Select [No.2] [G:].

If the background is [G] monochrome, press the

[MENU SEL ECT] key on the Rem ote con trol

transmitter to change to solid white.

3. View measurement point [No.2] and [No.3].

Lower the [G] color intensity only of the color point

whose [G] color is more intense than measurement

point [No.1].

4. View measurement point [No.10] and [No.11].

Lower the [G] color intensity only of the color point

whose [G] color is more intense than measurement

point [No.1], and raise the intensity of the point

whose color intensity is lower than measurement

point [No.1].

5. Now adjust the [MIN] tone for colors [R] and [B].

6. View measurement points [No.2], [No.3], [No.10]

an d [No.1 1 ] . Adjust the [ R ] and [ B ] of e ach

measurement point so that they have the same

color as measurement point [No.1].

Adjustment technique:

First, adjust [B:] of the point whose color is to be

adjusted so that it approximates that of [No.1]. If

[R:] is low at this time, the image will have cyan

cast, in which case [R:] is increased. On the other

hand, if [R:] is excessive, the image will have a

magenta cast, in which case [R:] is decreased.

Overall, a cyan cast makes it easy to see color shading.

7. Next, view measurement points [No.4], [No.5],

[No.12], [No.13] and make similar adjustments.

Then adjust measurement points [No.6], [No.7], [No.8],

[No.9], [No.14], [No.15], [No.16] and [No.17].

This completes the [MIN] tone adjustments.

9. Make similar another three tones as described in

steps 1 to 8 above.

No. 2 deviation range No. 10 deviation range No. 3 deviation range No. 11 deviation range

No. 4 deviation range No. 12 deviation range No. 5 deviation range No. 13 deviation range

Setup of a Cooling Fan Speed

When using this projector in the place where altitude is high, we recommend you to set a cooling fan’s speed as

“HIGH”. It is because the cooling efciency of a projector falls and the temperature inside a projector rises easily in

such a place, since the density of air becomes low.

Setting Method of Cooling Fan Speed

1. To display the OSD for cooling fan speed setup:

By the control panel By the remote control transmitter

A proper signal is input

No signal is input

2. Select the “HIGH” on the OSD using the button “ ”. To reset this setup, select the “NORMAL” using the button

“ ”.

3. The OSD will be ended by no operation for 10 seconds or change of input signal. To end immediately, use one of

buttons except buttons “ ”, “ ”, “ ”, “ ”, “RESET”, “MENU SELECT”, “MAGNIFY +/-/OFF”, “FREEZE” (when

no signal is input) or “POSITION” (when no signal is input).

1. Display the menu by the “MENU”

CP-X430W

Requesting projector status (Get command)

(1) Send the request code Header + Command data (‘02H’+‘00H’+ type (2 bytes) +‘00H’+‘00H’) from the computer

to the projector.

(2) The projector returns the response code ‘1DH’+ data (2 bytes) to the computer.

Changing the projector settings (Set command)

(1) Send the setting code Header + Command data (‘01H’+‘00H’+ type (2 bytes) + setting code (2 bytes)) from the

computer to the projector.

(2) The projector changes the setting based on the above setting code.

(3) The projector returns the response code ‘06H’ to the computer.

Using the projector default settings (Reset Command)

(1) The computer sends the default setting code Header + Command data (‘06H’+‘00H’+ type (2 bytes)

+‘00H’+‘00H’) to the projector.

(2) The projector changes the specified setting to the default value.

(3) The projector returns the response code ‘06H’ to the computer.

Increasing the projector setting value (Increment command)

(1) The computer sends the increment code Header + Command data (‘04H’+‘00H’+ type (2 bytes) +‘00H’+‘00H’) to

the projector.

(2) The projector increases the setting value on the above setting code.

(3) The projector returns the response code ‘06H’ to the computer.

Decreasing the projector setting value (Decrement command)

(1) The computer sends the decrement code Header + Command data (‘05H’+‘00H’+ type (2 bytes) +‘00H’+‘00H’)

to the projector.

(2) The projector decreases the setting value on the above setting code.

(3) The projector returns the response code ‘06H’ to the computer.

When a command sent by the projector cannot be understood by the computer

When the command sent by the projector cannot be understood, the error command ‘15H’ is returned by the

computer. Some times, the projector ignores RS-232C commands during other works. If the error command ‘15H’ is

returned, please send the same command again.

When data sent by the projector cannot be practice

When the command sent by the projector cannot be practiced, the error code ‘1cH’ +‘xxxxH’ is returned.

When the data length is greater than indicated by the data length code, the projector will ignore the excess data code.

Conversely, when the data length is shorter than indicated by the data length code, an error code will be returned to

the projector.

NOTE:

Operation cannot be guaranteed when the projector receives an undefined command or data.

Provide an interval of at least 40ms between the response code and any other code.

The projector outputs test data when the power supply is switched ON, and when the lamp is lit. Ignore this data.

Commands are not accepted during warm-up.
