such as broadcasters and food retailers where color accuracy and esh tones are critical.

Tiling Capability with Frame co mpensation Page 39
Up to 25 panels (5 wide x 5 high) can be combined to create a single large image (i.e., video wall) or oth er high-im pa ct signage. A
fram e compesation function i s i ncorporated to compensate the width of panel bezels so that images are displayed with the utmost
accuracy.

PiP, PoP and Side-by-side Pages 37 and 43
Picture-in-Picture and Pic ture- out-of-Picture are available when you want to display video c ontent from a video input source in the
sub picture and display the PC input source in the main picture, and vi ce versa.

x can displ ay these two input sources in the Side-by-si de mode, ideal for broadcastin g

and video-confer encing appli cations.

Programmable Scheduling F unction Pages 28, 29 and 38
The monitor s operating schedule can be programmed for up to seven different sc heduled time intervals by time, day of the week
and input port. This allows video content from different inputs to be displayed on certain monito rs within the same installation
ac cording to the sc hedule, and extends the mo nitor s life and saves the power by turning it off during those hours or days it i

s n ot in

use.

Prepar ation for use

Eng lish-13

P-1 Preparation for installation

This LCD has a temperature sensor and cooling fan. If the LCD
bec o mes hot, the co oling fan will turn o n auto matic ally. If the
LCD becomes overheated, the Caution menu will appear.
If the Caution menu appears, stop using the monitor and
all ow it t o cool. When the LCD monitor i s used in an enclosure
or with prot ection on LCD surface, please check the in side
temperatur e of the monitor by HEAT STATUS (See page 40). If
the temperature is higher than the normal level, set COOLING
FAN to ON using the SCREEN SAVER func tio n (See pag e 40).

To avoid the monitor from falling
When installing the mo nitor using the tabletop stands (o ptional),
take measures to prevent the monitor from falling over in case
of an eart hquake or other disaster to lessen the p robability of
injury and damage r esulting from the fall.
As shown in the

gure, se c ure the monitor to a solid wall o r
pillar using rope (co mmercially available) strong eno ugh to bear
the weight of the monitor. [LDT323V: approximatel y 14.5 kg ( with
the optional stands)]
Use of screw hooks (with opening) i s recommended.

360 mm

CAUTION:
The effect of the fall prevention substa ntially depends

on the strength of brackets and base to which the fall
prevention dev ices is attached. When you cannot ensure
suf

cient strength, provide adequate reinfo rc ement.

Though the recommen ded fall prevention is intended to

lessen the probability of injury a nd dama ge, it doesn t
assure its effectiveness against any kind of earthquake or
disaster.

Do not sleep where the monitor may topple o ver or fall in

case of an earthquake or other disaster.

Befo re moving the mo nitor, remo ve the rope that is

securing the monitor. Failure to do so may result in injury or
breakdown of the monitor.

mounting procedures can result in damage to the equipment or
injury to the user or inst a ller. Pr oduct warranty does not cover
damage caused by improper installation.
Failure to follow these reco mmendations can vo id your
warranty .
Use M6 screws (having a length 10 mm l onger t han t he
thickness of the mo unting bracket) and tighten them securely.
Prevent the screw s from loosening using spring washers, etc.

RS-232C Remote control

By c onnec ting multiple LCD monito rs and a c omputer using RS-232C cables (commerc ially available), you c an co ntrol the monitors
from the computer for the following operations:
Power ON or OFF
Switc hing between input signals
Volume control and mute
Auto s etup
Check of the internal temperature of the monito r, etc.
Connection

Before making co nnec tio ns, turn o ff the pe rsonal c omputer and the monito rs.
NOTE:

For connection with a 25-pin serial port connector on the computer, a conversion adapter (commercially available) is required.

This LCD monitor uses RXD, TXD and GND lines for RS-232C co ntrol.
Use RS-232C cables of reverse type (c ommercially available).

2) Contr ol command diagram
Th e command is structured by th e address code, function code, data code and end code. The length of the command is

different for each fu nct ion.

NOTE:

This example shows a basic command that is used when a single computer and a singl e monitor are connected.

When you want to connect multiple monitors or perform complicated c ontrol using other commands than the basic

commands, contac t your dealer for advanced c ommand speci

cations.

To use terminal software, send a text

3) Control sequence

(1) A command is sent f rom the computer to the monit or. (Commands should be sent at intervals of at least 600 ms.)

(2) Th e monitor sends a return command within 600 ms* after receiving and encoding t he command. If the monitor fails to

rec eive the c o mmand, it doesn t send any return c ommand.
(3) The computer checks th e return comm and to see that the command it sent was executed or not.
(4) The monitor sends various c o des o ther than the return c o de. While RS-232C contro l sequenc e is in pro gress , rejec t othe r

Imag e pers iste nc e
Please be aware that LCD Technol ogy may experience a phenomenon know n as image persistence. Ima ge persistence occurs

when a residual or ghost image of a previous image remains visible on the screen. Unlike CRT monit ors, L CD monitors i mage
persi stence is not permanent, but constant images being displayed for a long period of time should be avoided. To al leviate
im age persistence, tu rn off the monitor for as long as the previous image was displayed. For example, if an image was on the
mon itor for one hour and a residu al image rema ins, the mon itor shoul d be turned off for on e hour to erase the i mage.
