Controlling the LCD monitor via RS-232C Remote Control
This LCD monitor can be controlled by connecting a personal computer with a RS-232C terminal.
Functions that can be controlled by a personal computer are:
• Power ON or OFF
• Switching between input signals
Connection
LCD Monitor + PC
NOTE:If your PC (IBM or IBM compatible) is equipped only with a 25-pin serial port connector, a 25-pin serial port adapter
is required. Contact your dealer for details.
* RS-232C OUT terminal can connect MDT402S / MDT461S only. Do not connect other equipment.
The following control sequence is used for a single MDT402S / MDT461S. To control multiple MDT402S / MDT461S monitors that
are daisy-chained together please use the extended control command. Instructions for the extended control command can be found
on the CD included with the display. The file is called “External_control_MDT4XXS.pdf ”. When using the following control
commands, all of the daisy-chained monitors can be controlled at the same time from one monitor. Reply and status commands,
however, will only pertain to the primary monitor, not secondary monitors.
1) Interface
This LCD monitor uses RXD, TXD and GND lines for RS-232C control.
2) Control command diagram
The command is structured by the address code, function code, data code and end code. The length of the command is
different for each function.
[Address code] 30h 30h (ASCII code, '0' '0'), fixed.

3) Control sequence
(1) The command from a computer to the LCD monitor will be sent in 400ms.
(2) The LCD monitor will send a return command 400ms* after it has received and encoded. If the command isn’t
received correctly, the LCD monitor will not send the return command.
(3) The personal computer checks the command and confirms if the command, which has been sent, has been executed or not.
(4) This LCD monitor sends various codes other than return code. When having a control sequence by RS-232C, reject other
codes from personal computers side.
*: The sending time of return command may delay depending on the condition (during changing of the input signal, etc.).
Example: Turn the power ON ( ’ ’ is for ASCII code)
4) Operation commands
The operation commands execute the basic operation setting of this LCD monitor.
It may not operate when changing the signal:
• POWER OFF command should be operated over 1 minute after the power is turned on.
• POWER ON command should be operated over 1 minute after the power is turned off.
           * This operation is enabled when “S-VIDEO MODE” is “SEPARATE”.
5) Read command
Host computer sends the command without Data-code to monitor.
After receiving this command, the monitor returns the command with Data-code of current status to host computer.
< ex. > When Host computer ask Power status of monitor, the status of monitor is powered-on.

Features
Reduced Footprint: Provides the ideal solution for environments requiring superior image quality but with size and weight
limitations. The monitor’s small footprint and low weight allow it to be moved or transported easily from one location to another.
Color Control Systems: Allows you to adjust the colors on your screen and customize the color accuracy of your monitor to a
variety of standards.
Natural Color Matrix color matching Control System with sRGB: Combines Six-axis color control and the sRGB standard.
Six-axis color control permits color adjustments via six axes (R, G, B, C, M and Y) rather than through the three axes (R, G
and B) previously available. The sRGB standard provides the monitor with a uniform color profile. This assures that the colors
displayed on the monitor are exactly the same as on the color printout (with sRGB supporting operating system and sRGB
printer). This allows you to adjust the colors on your screen and customize the color accuracy of your monitor to a variety of
standards.
sRGB Color Control: A new optimized color management standard which allows for color matching on computer displays
and other peripherals. The sRGB standard, which is based on a calibrated color space, allows for optimal color representation
and backward compatibility with other common color standards.
OSD (On-Screen Display) Controls: Allow you to quickly and easily adjust all elements of your screen image via simple to
use on-screen menus.
Plug and Play: The Microsoft
® solution with the Windows® 95/98/Me/2000/XP operating system facilitates setup and
installation by allowing the monitor to send its capabilities (such as screen size and resolutions supported) directly to your
computer, automatically optimizing display performance.
Intelligent Power Manager System: Provides innovative power-saving methods that allow the monitor to shift to a lower
power consumption level when on but not in use, saving two-thirds of your monitor energy costs, reducing emissions and
lowering the air conditioning costs of the workplace.
Multiple Frequency Technology: Automatically adjusts monitor to the display card’s scanning frequency, thus displaying the
resolution required.
Full Scan Capability: Allows you to use the entire screen area in most resolutions, significantly expanding image size.
VESA Standard Mounting Interface: Allows users to connect their LCD monitor to any VESA standard third party mounting
arm or bracket. Allows for the monitor to be mounted on a wall or an arm using any third party compliant device. MITSUBISHI
ELECTRIC  recommends using mounting interface that comply with TÜV-GS and/or UL1678 standard in Nor th America.
DVI-D: The digital-only subset of DVI ratified by the Digital Display Working Group (DDWG) for digital connections between
computers and displays. As a digital-only connector, analog support is not provided off a DVI-D connector. As a DVI-based
digital only connection, only a simple adapter is necessary for compatibility between DVI-D and other DVI-based digital
connectors such as DFP and P&D.
Tiling, Frame compensation: Demonstrates multiple screens with an accurate image and compensates for the bezel width.
ZOOM: Expands the image individually for horizontal and vertical direction.
RS-232C daisy chain: You can control the multiple monitors by controller or wireless remote controller.
Self-diagnosis: When an internal error should occur, a failure state will be indicated.
Automatic Long Cable Compensation: Automatic long cable compensation prevents image quality degradation (color shift
and dull signals) caused by long cable lengths.

Troubleshooting
No picture
• The signal cable should be completely connected to the display card/computer.
• The display card should be completely seated in its slot.
• Front Power Switch and computer power switch should be in the ON position.
• Check to make sure that a supported mode has been selected on the display card or system being used.
(Please consult display card or system manual to change graphics mode.)
• Check the monitor and your display card with respect to compatibility and recommended settings.
• Check the signal cable connector for bent or pushed-in pins.
Power Button does not respond
• Unplug the power cord of the monitor from the AC outlet to turn off and reset the monitor.
Image persistence
• Please be aware that LCD Technology may experience a phenomenon known as Image Persistence. Image Persistence
occurs when a residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, LCD
monitors’ image persistence is not permanent, but constant images being displayed for a long period of time should be
avoided. To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example,
if an image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to
erase the image.
NOTE:As with all personal display devices, MITSUBISHI ELECTRIC recommends displaying moving images and using a
moving screen saver at regular intervals whenever the screen is idle or turning off the monitor when not in use.
Image is unstable, unfocused or swimming is apparent
• Signal cable should be completely attached to the computer.
• Use the OSD Image Adjust controls to focus and adjust display by increasing or decreasing the fine adjustment.
When the display mode is changed, the OSD Image Adjust settings may need to be re-adjusted.
• Check the monitor and your display card with respect to compatibility and recommended signal timings.
• If your text is garbled, change the video mode to non-interlace and use 60Hz refresh rate.
Image of component signal is greenish
• Check to see if the DVD/HD input connector is selected.
LED on monitor is not lit (no green or red color can be seen)
• Power Switch should be in the ON position and power cord should be connected.
• Make certain the computer is not in a power-saving mode (touch the keyboard or mouse).
RED LED on monitor is blinking
• A certain failure might have occurred, please contact your nearest authorized MITSUBISHI ELECTRIC service facility.
Display image is not sized properly
• Use the OSD Image Adjust controls to increase or decrease the coarse adjustment.
• Check to make sure that a supported mode has been selected on the display card or system being used.
(Please consult display card or system manual to change graphics mode.)
Selected resolution is not displayed properly
• Use OSD Display Mode to enter Information menu and confirm that the appropriate resolution has been selected.
If not, select corresponding option.
No Sound
• Check to see if speaker cable is properly connected.
• Check to see if mute is activated.
• Check to see if volume is set at minimum.
Remote Control is not available
• Check the Remote Control’s batteries status.
• Check if batteries are inserted correctly.
• Check if the Remote Control is pointing at the monitor’s remote sensor.
“SCHEDULE”/“OFF TIMER” function is not working properly
• The “SCHEDULE” function will be disabled when the “OFF TIMER” is set.
• If the “OFF TIMER” function is enable and the power to the LCD monitor is turned off if the power supply is interrupted
unexpectedly, then the “OFF TIMER” will be reset.
Either light vertical or horizontal stripes may appear, depending on the specific display pattern. This is no product fault or
degradation.
