l
After the projector executes a command, it generates a response.

To prevent buffer overrun, don’t send another command until you receive the next command
prompt.
Value-based command methods
Absolute values and adjustment values
You can use the command’s target range to set an absolute value for a command or cause an
adjustment to be made to the current value. To create an adjustment command, add a plus (+) or
minus (-) symbol instead of the equal symbol (=) before the value change you want to enter.
All absolute values you enter must be within the command target range, and all adjustment values
must equal a number within the command target range.
See the following examples for adjusting projector brightness:
>get brightness
brightness=55
>set brightness=65
brightness=65
>set brightness+5
brightness=70
>set brightness-15
brightness=55
Video source specification values
You can use the source input field described in Source selection controls on page 72 in a command to
set an absolute value or adjustment value to a source other than the active source. You can do this
while the selected source is inactive, but the source device must be connected or you will receive an
invalid command response.
See the following examples, where both an HDMI connector and a VGA 1 input are connected:
>set input=hdmi
input=hdmi
