Using the remote controlMake 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 sensorBefore 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.

12 | « Features »

Operating range of the remote controlPoint 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 DisplayConnecting the power cableBefore 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.

14 | « Getting Started »

Tiling configurationThis feature provides a single large-screen matrix (video-wall) using up to 25 displays (up to 5 set horizontally and 5 set vertically). This function requires a daisy-chain connection. For more details, see “Interconnecting the displays”.

CAUTION: Keep the displays horizontally or vertically straight when the individual displays are tiled together.

ü

The displays can be tiled in portrait or landscape orientation. Ensure that the display is oriented as shown in the following illustrations.

NOTE: In portrait orientation, the lifetime of the backlight is shorter than in landscape orientation.

« Getting Started » | 15

Interconnecting the displaysYou can interconnect multiple displays to create a daisy-chain configuration for multi-screen applications such as a video wall.

NOTE:

• The daisy-chain connection allows up to 25 LCD displays. However, the maximum number of connectable LCD displays may be limited. It is recommended to check the number of connectable LCD displays in your installation environment in advance.

• To protect the connected equipment, turn off the main power switch before making connections.

1. Use the DVI cross cable/RS-232C cross cable/HDMI cable to connect the computer to this display, and from display to display.

2. Press the [MENU] button to display the OSD menu and select [Multi Display Control] [Tiling] to enable the tiling mode and select [Monitor ID] to set the display’s ID number.

For more details on setting the multi-display functions, check the on-screen menu provided by the display.

NOTE: Once connected, press the [INPUT] button to set the video input according to the type of connection made.

18 | « Getting Started »

Connecting to the InternetYou 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 controlThe 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).

« Getting Started » | 19

To set the remote control commands:

NOTE: Please contact your local agent for details of the control functions, including network parameters and command sets.

1. Select [MENU] [Setup] [Control Setting] to enable the LAN connection as the communication interface used for the serial communication function.

2. Setup the network parameters.

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 deviceYou 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.

2. Insert USB storage medium into the USB port of the display.

3. Use the [INPUT] button on the remote control or the [SOURCE] button on the display’s control panel to select USB as the input source.

4. Select [MENU] [Setup] [Software update (USB)] to update the firmware.

NOTE: Some USB hubs may not work. If a USB device is connected using a USB hub is not detected, connect it to the USB port on the display directly.
