NOTES
l The display won’t respond to RS-232 commands when it is in a low power state (soft off).
Disable Power saving mode to prevent the display from entering a low power state. See
Power saving mode on page62.
l When you first turn on the display, the RS-232 connector operates in a special diagnostics
mode instead of control mode, and the display won’t respond to control commands. In
addition, the connected control system or terminal emulation program might receive
unexpected data characters.
Program a connected control system to ignore the unexpected data characters and only
send commands after it receives the command prompt (>).
If you haven’t disabled Power saving mode, you’ll see the unexpected characters every
time you turn on the display.
CORRECT
>set input=HDMI1
INCORRECT
>set HDMI1
To use the room control system to get information about the display or to adjust display settings,
send commands after receiving a command prompt (>), and then wait for the display’s response
before sending another command.

volume=55
>
If you send a command that the room control system doesn’t recognize, you receive an invalid
command response.
The example contains an extra space in the volume command.
