Using the remote control
Make sure to point the remote control at the IR sensor on the display.
If the remote control is not working, replace the batteries with new ones and make sure that they
are correctly inserted: place two 1.5V AAA batteries matching the (+) and (–) signs to the (+) and (–)
indications of the battery compartment.
Setting up the IR sensor
Before using the infrared remote control, the IR sensor must be positioned correctly. The IR sensor
is the small black box located on the back side of left of the LCD display.
To set up the IR sensor:
1. Remove the two screws as indicated in the image below.
2. Unthread the cables from the cable clip.
3. As the IR sensor moves with the magnet, hold and place the IR sensor onto the back side of
the LCD display and slowly slide the IR sensor until it is in place.
Reverse this procedure to return the sensor to its original position.
It is strongly recommended that you place the IR sensor at the bottom-left corner or bottom-right
corner of the back side of the display. In the case of a daisy-chain connection, always place the IR
sensor at the outer bottom-corners, ensuring the IR sensors will receive the signal across a wide
angle.

Page 12
Operating range of the remote control
Point the infrared remote control toward the display’s remote control sensor when operating the
remote control. Ensure the remote control is aimed at the correct location where the IR sensor is
placed. Use the remote control within a distance of less than 10m/32.8ft from the IR sensor, and a
horizontal and vertical angle of less than 30 degrees.
30°30°
NOTE:
• Using the remote control beyond this distance, or with an object obstructing the
path of the signal, may cause a communication failure.
• The remote control may not function properly when the IR sensor on the display is
under direct sunlight or strong illumination.

Getting Started
Setting up the LCD Display
Connecting the power cable
Before making any connections, make sure that the main power switch is off.
1. Plug the power cord into the display.
2. Fully insert the plug into the power outlet socket. Loose connections may cause noise. Do not
plug and unplug the power cord repeatedly in a short period of time.
NOTE:
• This display is equipped with a three-pronged grounded plug (a plug with a third
grounding pin). This plug will fit only into a grounded power outlet as a safety feature.
If your outlet is not suitable for the three-pronged plug, consult an electrician for a
solution. Do not bypass the safety purpose of the grounded plug
• The supplied power cord varies depending on the country where you purchased this
apparatus. For all cases, use a power cord that matches the AC voltage of the power
outlet and has been approved by and complies with the safety standard of your
country.
• When disconnecting the AC power cord, be absolutely sure to disconnect the plug
at the socket outlet first.

Connecting to the Internet
You can connect this display and a computer in a network through a LAN hub by using a LAN
straight cable.
To connect to the Internet:
1. Turn off the main power switch of the computer and this display. If you make a connection
while the power is on, the devices may fail.
2. Use the LAN straight cables to connect the computer, the LAN hub, and the display.
NOTE: When you use a LAN cross cable, you can connect the display and the computer
one-to-one without using a LAN hub depend on the type of connection your computer
supports.
LAN remote control
The display supports two communication interfaces: LAN and RS-232C. By using the two
communication interfaces, you can control displays remotely:
• Use an RJ-45 connector for Ethernet networking as described above.
• Use an RS-232C cross cable (reversed).
For connection with a 25-pin serial port connector on the computer, an adapter (commercially
available) is required.
For direct connection using RS-232C, use the RxD, TxD, and GND transmission lines.
When you connect the display and the computer using a LAN hub and a LAN cable, and configure
the network settings using [Ethernet Setting] in the [Setup] menu of the OSD, you can control the
LCD display remotely (use the same commands as for RS-232C).
18 | « Getting Started »
Page 19
To set the remote control commands:

3. Set the IP address and the port number (4660) using the application program of your
computer to perform the socket communication.
4. Send the control command via TCP/IP socket communication.
5. Check the return command sent from the LCD display. When it is received successfully, the
setting is complete.
NOTE: If [LAN] is selected, [RS-232C] will not be activated, even if a cable is attached,
and vice versa
Connecting to a USB device
You can update the firmware on the LCD display via the USB port.
To update the firmware:
1. Download the latest firmware for the LCD display to a USB storage medium.
