Features
The JME-SA200 screen alignment controller is designed to check the
operation of the JumboTron screen and to adjust the position, size,
brightness and picture quality of the image. The wireless remote control
system using the public telephone system assures reliable data
communication.
The main functions of the JME-SA200 are as follows:
Wireless remote controller using a cellular phone
Interactive data communication is carried out via the cellular phone
connected to the JME-SA200 and the modem connected to the JTC-C200
ICU controller. This data communication method using the public
telephone system offers a highly reliable wireless remote control system.
The JME-SA200 can also be used as a wired remote controller by
connecting to the ICU controller using a connecting cable (with a
maximum cable length of 1,000 m).
Checking the operation of the screen
Activating the test signal generator built in the display units which
constitute the screen, the JME-SA200 displays the stair step and color bar
signals on the screen for checking the operation of each display unit.
Adjusting the luminance of a specified unit or cell
The JumboTron screen may partially degrade the brightness or color
uniformity after long use. The JME-SA200 can correct the uniformity by
adjusting the luminance or color temperature of a specified unit or cell.
Adjusting the position and size of the image
The JME-SA200 can shift the image on the screen vertically or
horizontally, and change the image size (expansion/reduction level). The
JME-SA200 automatically calculates and displays the aspect ratio of the
adjusted image.
The adjusted data can be stored in the memory of the ICU, and recalled
instantly by specifying the memory number.
Adjusting the brightness of the image
The JME-SA200 can adjust the brightness of the whole screen to 16 levels.
Setting the area of a computer graphics image mixed with a
video image
When displaying a video image over the monochrome portion of a
computer graphics image, the JME-SA200 can specify the area to be
mixed as R, G and B data.
Adjusting the picture quality on the screen
The JME-SA200 can adjust the color, hue and sharpness of the image on
the screen.
Storing up to 256 unit or cell numbers
The JME-SA200 can register up to 256 unit or cell numbers to be adjusted
or repaired to store these numbers in the memory of the ICU.
