About This Manual
This instruction manual is mainly aimed at the maintenance/service
personnel.
It explains how to use the JME-UA200 unit alignment controller, which is
used to adjust and inspect the JumboTron display units of the JumboTron
system.
Precautions
On safety
•Do not forcibly bend the power cord. Do not place or drop any heavy
object on it. If the power cord has been damaged, a fire or electric shock
hazard may occur.
•To disconnect the power cord, pull it out by the plug. Never pull the cord
itself.
•Do not use a damaged power cord.
•Do not drop any liquid or solid object into the cabinet.
On cleaning
•Clean the case and front panel with a dry soft cloth, or a soft cloth
slightly moistened with a mild detergent solution. Do not use any organic
solvents, such as alcohol or benzine which might damage the finish.
•Be sure to unplug the unit before cleaning.

The JumboTron system displays video images on a large screen
(JumboTron screen) located either outdoors or indoors. Images from video
sources such as a VCR, video camera and computer can be displayed on
the screen.
The JumboTron system provides superb bright images with high
resolution, regardless of whether it is day or night, indoors or outdoors.
Images to be displayed on the JumboTron screen
The JumboTron system can display the following three types of images:
[a] Video images input from equipment such as a VCR, video camera
and video disc (INPUT 1)
[b] Computer graphics (INPUT 2)
[c] Mixed images of INPUT 1 and INPUT 2
(INPUT 1 images are superimposed on the monochrome area of
INPUT 2 images.)

Structure of the JumboTron screen
Two types of the JumboTron screen are available. One is the conventional
CRT type screen in which light emitting bodies of three primary colors (R,
G and B), “Trinilite,” are used as the light emitting element. The other is
the new LED type screen in which light emitting diodes of the three
primary colors are used.
The basic element of the JumboTron screen is an RGB trio (dot).
A “cell” consists of the dots arranged at a certain interval (picture element
pitch) and a “unit (JumboTron display unit)” consists of 12 cells for the
CRT type and 16 cells for the LED type.
There are four unit types, the JTU-35 series (with 35-mm picture element
pitch) and JTU-17 series (with 17.5-mm pitch) of the CRT type, and the
LDU-15 series (with 15-mm pitch) and LDU-30 series (with 30-mm pitch)
of the LED type. You can configure a large JumboTron screen by
arranging the JumboTron display units vertically and horizontally to suit
various uses or locations.

The JME-UA200 unit alignment controller is designed to adjust the
luminance of a JumboTron display unit, cell or pixel and to check their
operations.
The main functions of the JME-UA200 are as follows:
Eleven types of test signals
The built-in test signal generator of the controller displays eleven types of
test signals, allowing you to check various circuits and functions of a
JumboTron display unit.
Luminance adjustment of a cell and pixel as well as the whole unit
You can specify a cell or pixel (a single light emitting element of R, G and
B) which composes a JumboTron display unit and adjust its lumincance.
This allows you to obtain luminance uniformity of the whole screen.
Automatic luminance adjustment
After measuring the data of a cell which is emitting light correctly using a
unit alignment sensor (not supplied), you can adjust other cells
automatically to the same data as the correct cell.
Function check of a JumboTron display unit
You can check whether a JumboTron display unit is operating properly, or
check the current conditions of a unit.
Demonstration
The controller can display a test signal automatically on a small screen,
which is a combination of several units (up to 16 units), for a
demonstration.

You can display eleven types of test signals on a JumboTron display unit.
Use this mode to clear the cause of the malfunctions of a unit or to check
the operation of a unit, cell or pixel after replacing or adjusting it.
After selecting the type of the test signal, you can specify precisely the
luminance, brightness, scroll speed and color bar width of each test signal.

•If you change the CLK setting while the JumboTron display unit is in
operation, the unit cannot receive the signal from this controller. In this
case, disconnect the unit, then turn on back the power of the unit.
•If you increase the number of display lines with SPD (scroll speed) set to
01, the JumboTron display unit cannot receive the signal from the
controller correctly. If you want to increase the scroll speed, specify the
less number of display lines.

The width of one line of the color bar is 1 dot (a set of R, G
