bits, no parity,1 stop bit and no flow control. 
6. Press . The Vision 90t/100t responds with “+>” to indicate that it is ready to 
accept commands. 
7. Start your color analyzer. Position the sensor approximately 6 to 12 inches from the 
screen, facing it at a slight angle (upward or to one side) so that the color of the screen is 
included in the calibration.

Serial Command Syntax
Table A-1 lists the serial command set for color gamut adjustments. The “Parameter 
(min/max)” column shows the valid parameter ranges, or “NA” for commands that take no 
parameters. 
When you enter a valid command, the Vision 90t/100t executes it and acknowledges it with a 
plus sign on the command line (+ >). When you enter an invalid command – one that is 
misspelled or followed by values outside the valid range for that command – the Vision 
90t/100t ignores it and returns a minus sign (- >).

Adjusting the Gamut
1. In HyperTerminal, type gamut white and press . The Vision 90t/100t 
displays a white field on the screen and the current x and y coordinates for white on the 
command line. 
2. Using the color analyzer, measure the x and y coordinates for about 15 seconds. Make a 
note of the results. 
3. In HyperTerminal, use the gamut set white command to change the x and y 
coordinates to the values you obtained in Step 2. For example, if the readings were 
x=0.284 and y=0.294, type gamut set white 0.284 0.294 and press . 
4. To confirm the change, repeat Step 1. The displayed x and y values should match what 
you just entered. 
5. Type gamut red and press . The Vision 90t/100t displays a red field on the 
screen and the current x and y coordinates for red on the command line. 
6. Repeat Step 2. 
7. In HyperTerminal, use the gamut set red command to change the x and y 
coordinates to the values you obtained in Step 6. 
8. To confirm the change, repeat Step 5. The displayed x and y values should match what 
you just entered. 
9. Type gamut green and press . The Vision 90t/100t displays a green field 
on the screen and the current x and y coordinates for green on the command line. 
10. Repeat Step 2.
GAMUT GREENNANADisplays green field on screen for 
measuring x and y coordinates; 
shows current x and y coordinates 
for green on the command line. 
GAMUT BLUENANADisplays blue field on screen for 
measuring x and y coordinates; 
shows current x and y coordinates 
for blue on the command line. 
GAMUT SET WHITE [x] [y]x = 0.0 / 0.8 
y = 0.0 / 0.9
YESSets x and y coordinates for white.
GAMUT SET RED [x] [y]x = 0.0 / 0.8 
y = 0.0 / 0.9
YESSets x and y coordinates for red.
GAMUT SET GREEN [x] [y]x = 0.0 / 0.8 
y = 0.0 / 0.9
YESSets x and y coordinates for green.
GAMUT SET BLUE [x] [y]x = 0.0 / 0.8 
y = 0.0 / 0.9
YESSets x and y coordinates for blue.
GAMUT OFFNANAApplies new gamut setting (if 
changed) and goes back to normal

the screen and the current x and y coordinates for blue on the command line. 
14. Repeat Step 2.
15. In HyperTerminal, use the gamut set blue command to change the x and y 
coordinates to the values you obtained in Step 14. 
16. To confirm the change, repeat Step 13. The displayed x and y values should match what 
you just entered. 
17. Type gamut off and press . The Vision 90t/100t stores the new x and y 
coordinates and returns to normal operation.
