CAT5 Tx BOX
1  USB (B type)
Connector for receiving the power supplied from the USB 
device such as the computer. By connecting a USB cable, you 
can control the CAT5 Tx BOX using the control commands 
transmitted over the USB cable.
CAUTION:
We have checked that the power is supplied and the control 
commands are transmitted properly via the USB connector 
by connecting it with our computers according to the USB 
standards.
When the CAT5 Tx BOX is combined with your computer 
system or USB hub system, check in advance that it operates 
properly. 
2  EXTERNAL CONTROL (D-SUB 9-pin)
When the communication via the USB connector is unusable, 
this connector can be used for RS-232C communication with 
the control device such as the computer. 
NOTE:
RS-232C connection isn’t necessary when the COM port 
number set by the USB driver is used. Make selection using the 
input select switch (USB/RS-232C) (
5), as necessary. 
3  RGB IN (MINI D-SUB 15-pin)
Connector for receiving the analog RGB video signal from the 
computer.
4  RGB OUT (MINI D-SUB 15-pin)
Video connector for buffering and outputting the analog RGB 
video signal received by the RGB IN connector (
3). 
5  Input select switch (USB/RS-232C)
Switches the control input between the USB connector and the 
RS-232C connector.
6  CAT5 OUT (Modular connector 8-pin)
Connector for converting and outputting the video signal 
received by the RGB IN connector (
3) and the control signal 
transmitted via the USB connector (
1) or the RS-232C 
connector (
2) to transmit them on the CAT5 long cable.
CAUTION:
Never connect network devices to the CAT5 IN and OUT 
connectors. If you do so, they may adversely affect with each 
other, causing breakdown.
7  Composite sync signal level switch
Switches the composite sync signal level.
The TTL level and the 0.3 V level are switched.
8  Auxiliary power supply input connector (DC IN 
5 V)
Though the power is supplied from the above-mentioned 
USB connector, an auxiliary DC power adapter (commercially 
available) is also available. When +5 V (according to the product 
specifi cations) is supplied from the above-mentioned DC power 
adapter, the power supply is automatically switched from the 
USB connector. (You cannot use both at the same time.)
CAUTION:
•  Don’t apply a voltage out of the specifi ed range to the 
auxiliary power supply input connector or connect it with 
incorrect polarity. If you do so, the connected devices may 
be overheated or damaged.
•  The auxiliary power supply input connector isn’t intended 
for general use. Commercial DC power connectors are 
available in different shapes. When you want to use this 
connector, consult a qualifi ed electrician or your dealer in

 P-1   Preparation for installation
Ventilation requirements for enclosure mounting
To allow heat to disperse, leave space around the monitor as 
shown in the fi gure below.
CAUTION:
Don’t block the holes in the rear of the monitor shown in the 
fi gure above. If they are blocked, heat accumulates inside the 
monitor, causing breakdown. The upper limit of the operation-
guaranteed ambient temperature when the monitor is installed 
in the landscape position is 40˚C. When installing the monitor 
in a case or an enclosure, ensure adequate ventilation to keep 
the temperature inside the case 40˚C or lower by providing 
a cooling fan or ventilation holes in the case. The upper limit 
when the monitor is in the portrait position is 35˚C.
This LCD has a temperature sensor and cooling fan. If the LCD 
becomes hot, the cooling fan will turn on automatically. If the 
LCD becomes overheated, the “Caution” menu will appear. 
If the “Caution” menu appears, stop using the monitor and 
allow it to cool. When the LCD monitor is used in an enclosure 
or with protection on LCD surface, please check the inside 
temperature of the monitor by “HEAT STATUS” (See page 50). If 
the temperature is higher than the normal level, set “COOLING 
FAN” to ON using the SCREEN SAVER function (See page 46). Install the monitor on a wall or ceiling strong enough to 
support its weight where the screen is easy to view, using 
commercially available wall or ceiling mount brackets.
Determine the installation location
CAUTION:
DO NOT ATTEMPT TO INSTALL THE LCD MONITOR BY 
YOURSELF.
Installing your LCD monitor must be done by a qualifi ed 
technician. Contact your dealer for more information.
CAUTION:
MOVING OR INSTALLING THE LCD MONITOR MUST BE 
DONE BY THREE OR MORE PEOPLE.
Failure to follow this caution may result in injury if the LCD 
monitor falls.
CAUTION:
Do not mount or operate the monitor upside down, face up, or 
face down.
IMPORTANT:
Lay the protective sheet, which was wrapped around the LCD 
monitor when it was packaged, beneath the LCD monitor so as 
not to scratch the panel.Don’t block these holes.

 P-2   Installing the monitor  Carry out as necessary
Using the wall mount or ceiling mount
Lay the screen face down
Lay the protective sheet on a table, which was wrapped around 
the monitor when it was packaged, beneath the screen surface 
so as not to scratch the screen surface.
Failure to follow the correct mounting procedures can result 
in damage to the equipment or injury to the user or installer. 
Product warranty does not cover damage caused by improper 
installation.
Failure to follow these recommendations can void your 
warranty.
Use M8 screws (having a length 15 mm longer than the 
thickness of the mounting bracket) and tighten them securely. 
Prevent the screws from loosening using spring washers, etc. 
MITSUBISHI ELECTRIC recommends using mounting interface 
that comply with TÜV-GS and/or UL1678 standard in North 
America.
CAUTION:
For preventing the monitor from falling.
•  Install the monitor with metal brackets for wall or 
ceiling installation (commercially available) on your own 
responsibility. For detailed procedures of installation, refer 
to the instructions of the metal brackets.
•  To lessen the probability of injury and damage resulting 
from fall of the monitor in case of earthquake or other 
disaster, be sure to consult the bracket manufacturer for 
installation location.
•  To lessen the risk of falling of the monitor, thread 
commercially available rope through the handles at the 
right and left of the monitor and secure the rope to the wall 
mount brackets or ceiling mount brackets.
•  Do not sleep where the monitor may topple over or fall in 
case of an earthquake or other disaster.
•  Use screws having enough strength to support the LCD 
display monitor (made of stainless steel etc.).
