About external controls
In addition to using the display keypad or the remote control, you can control a display panel by using a serial
(RS232/RS485) link to send ASCII commands and receive responses to those commands.
You can also use discrete infrared (IR) control codes to program a third-party remote control unit. For more
information, see Using discrete IR codes (on page 23).
Sending communications over an RS232 or an
Ethernet connection
Learn how to send messages from a control computer to a display panel over an RS232 or an Ethernet link.
The control computer or device must be running one of the following applications:
•
An audio/video control system such as those manufactured by AMX, Extron, or Crestron
•
The Video Wall Toolbox application
For more information on the Video Wall Toolbox application, see Using the Video Wall Toolbox application
(on page 15).
Configuring the RS232 port
Learn how to configure the RS232 port.
1.
Connect the control computer to the RS232 input on the display panel.
2.
Do one of the following.
•
If you are using the Video Wall Toolbox application, to connect the control computer to the
display panel, select the COM: port.
For more information, see Using the Video Wall Toolbox application (on page 15).
•
If you are using an audio/video control system, complete the following to configure the
RS232 port on the system.
a.
Select no parity, 8 data bits, 1 stop bit, and no flow control.
b.
Set the baud rate to 115200, so that it matches the RS232 port on the display panel.
Ethernet connection command and response format
If you are using the Video Wall Toolbox application, select the IP address of the display panel. If you
are using an audio/video control system, configure the control system to the IP address of the display
panel and send commands using the Telnet protocol.
