Make sure that there is nothing obstructing the infrared beam between the remote control and the IR
receiver on the display.



If the effective range of the remote control decreases, or it stops working, replace the batteries with new
ones.



The remote control may fail to operate if the infrared remote sensor is exposed to bright sunlight or
fluorescent lighting.



Ambient conditions may possibly impede the operation of the remote control. If this happens, point the
remote control at the display, and repeat the operation.

Quick Setup

Table 3-1 gives a quick overview of the display installation process. The sections following this one provide
detailed instructions.

Table 3-1. Installation Overview

Installation Considerations

Proper installation of your display will ensure a satisfying viewing experience. Whether a display is installed
temporarily or permanently, the following should be taken into account to ensure the best performance of
the display.

Ambient Light

In general, minimise or eliminate light sources directed at the screen. Contrast ratio in your images will be
noticeably reduced if light directly strikes the screen, such as when a shaft of light from a window or floodlight
falls on the image. Images may then appear washed out and less vibrant. Direct sunlight may affect touch
operation.

Ambient Heat

Keep the ambient temperature constant and below 40°C (104°F). Keep the display away from heating and/or
air conditioning vents.

Revision Date:1/17/2020

26

NOTE

To safely mount the display on a wall:

• Use only the approved wall-mount kit designed for the display.

• Make sure the tilt degree of the wall does not exceed 2 degrees.

For more information of wall mount installation, refer to Appendix II: Installing a Wall
Mount on page 65.

Ventilation

If you are mounting the display in an enclosure, leave sufficient space on all sides between it and surrounding
objects, as shown in Figure 3-1. This allows heat to disperse, maintaining the proper operating temperature.

Figure 3-1. Ventilation Requirements for Enclosure Mounting

Mounting the Display

You can mount the display on a wall.
If you do decide to wall-mount the display, ensure that the wall-mount bracket is installed according to the

instructions included with it. The wall must be capable of supporting a redundant weight factor three (3) times
the weight of the display, or be reinforced.

We recommend that this be done by a custom installation specialist.

Connections to the Display

Proceed as follows to connect the display to your video sources, external controller(s) – if present – and AC
power.

When connecting your equipment:



Turn off all equipment before making any connections.



Use the correct signal cables for each source.



For best performance and to minimise cable clutter, use high-quality cables that are only as long as
necessary to connect two devices. (Don't use a 7m cable when a 1.8m cable will suffice.)



Ensure that the cables are securely connected. Tighten the thumbscrews on connectors that have them.

Connecting a Control System or PC

RS-232 Connection

Use a straight-through RS-232 cable with a 9-pin male connector to connect a PC or control/ automation
system (if present) to the RS-232 port on the display; see Figure 3-2.

For more information about using this connection, refer to External Control on page 50.

The display uses a simple text-based control protocol to take requests from control devices and to provide
responses to such devices. This section describes how to send control messages over a serial link between the
display and an automation/control system or a PC running a terminal emulation program such as Windows®
HyperTerminal or Tera Term.

RS232 Connection and Port Configuration

Connect your control system or PC to the RS232 input of the display as shown in Figure 3-2.
Configure the RS232 controller or PC serial port as follows: no parity, 8 data bits, 1 stop bit and no flow control.

Set the baud rate to 115200, to match that of the display RS232 port.

Command and Response Format

Commands sent from an automation/control system or PC to the display must have the following format:
[STX] [IDT] [TYPE] [CMD] ([VALUE] or [REPLY]) [ETX] [CR]
Where:



[STX] indicates the start of the command data (always 07).



[IDT] is the display ID (always 01).



[TYPE] is the command type:
00 = return to host (response from the LCD panel)
01 = read / action
02 = write



[VALUE] is the parameter setting for the command.



[REPLY] is the parameter setting for the command, acknowledged by the display in its response to a

command.



[ETX] indicates the end of the command data (always 08).



[CR] is the ASCII carriage return key (0x0D).

The display accepts commands in the form of infrared (IR) signals that conform to the NEC protocol. Each
display remote control button has an IR control code associated with it.

You can use these codes to program a third-party, “universal” remote control unit to work with the display.
These third-party products usually come with a computer software application for this purpose. For more
information, consult the documentation provided with the remote control unit.

IR Command Protocol

The IR control codes have the following characteristics:
Each code consists of the following:

- A leader pulse (a modulated pulse of 9 ms followed by a non-modulated pulse of 4.5 ms);

- 16 address bits (also called a “custom code”): eight (8) bits for the address followed by the logical inverse

of the address. The custom code for the display is 16559 decimal (0x40AF, binary 01000000 10101111).

- 16 data bits: eight (8) bits for the command followed by the logical inverse of the command

- An end pulse (a modulated pulse of 0.56 ms, similar to the modulated pulse in the ‘0’ and ‘1’ bits). The end

of the modulated pulse constitutes the end of the data transmission.
The carrier frequency is 38 kHz, with the modulated pulses having a 33% duty cycle.
Commands are sent at a maximum rate of 9 Hz.
For example, here is the NEC control code for the POWER button on the display remote control unit:

TCP Mode

Telnet Server/Client

Set the device to be a Telnet Server or Client.

Port Number

When in Server mode, assign the port number used to connect remotely. When in Client mode, assign the port
number for the device to connect to the remote site.

Remote Server IP Address

When in Client mode, the device will connect to the remote server with the IP address set here.

Client mode inactive timeout

When NET2UAR is operating in TCP client mode, it will always try to connect with the remote server. The time
configured here is for NET2UART to rebuild connection after timeout.

Server mode protect timeout

When NET2UART is operating in TCP server mode, it would protect the TCP connection from getting replaced
in the period of the time set here.

Revision Date: 1/17/2020

73

UDP Mode

Status

When TCP mode is set as Server mode or Client mode, the UDP mode would be disabled automatically, and
vice versa.

Local Port

Assign the port number here to allow the device to open for the remote site to send data via UDP. The IP
address of the remote site must be set in the Remote Address table, or NET2UART will ignore its data.

Remote Address

The Remote Address table allows 10 entries of remote site IP addresses and ports. When NET2UART is sending
data to network, the data will be sent to the each remote IP address entered in the table simultaneously. The
port number is the remote site port number that NET2UART will send data to via UDP.

If the port number is set as “0”, the NET2UART will use the port number that the remote site sends data from as
the destination port number, or use the local port number as the destination port number if the remote site
has not sent data to NET2UART.

Delimiter

SMTP

Character 1 & 2:
Set Character 1 and/or Character 2 to be the delimiter.
Once the delimiter is active, NET2UART would monitor all data received from UART. All data received

from UART will be stored in NET2UART internal buffer first, and will only be sent to Ethernet once the
delimiter is detected. If the delimiters have not been detected and the internal buffer of NET2UART is
stuffed, the incoming data will overwrite the previous data stored in NET2UART.

Drop Character:
The Drop Character is set to drop delimiter or not. If Drop Character is active, the delimiter received from

UART will not be sent out to Ethernet.
Silent time:

Once the Silent time is active, NET2UART will keep all data received from UART in its internal buffer and
check the time period of no data received from UART. It will then send out the internal data once the
time is out.
