preceded by a carriage return character (<CR>) and line feed character (<LF>) and then followed by a
carriage return character (<CR>) and line feed character (<LF>), as shown in the example below. Refer to an
ASCII table for more information about character codes if needed.

Commands and responses
To access display information or to adjust display settings using the room control system, send a command
after the command prompt (>), send a carriage return character or press ENTER, and then wait for the
response from the display. Responses are preceded by a carriage return character (<CR>) and line feed
character (<LF>) and then followed by a carriage return character (<CR>) and line feed character (<LF>). If no
command prompt is present, send a carriage return character to thedisplay. If the display is ready to receive
commands, it will show a command prompt (>) when the carriage return is received. See the example below.
