Invalid parameter—command with current value
Action command with unnecessary parameter—action command
Action command that is unavailable—action command
The following simplified example shows how the projector typically responds to
a request to change the active input source. Note that the three latter notifications
are delayed.
Room controller commands
In the following tables, if the parameter listing for a particular command is
“None,” that command requires no parameter. Some commands are valid only
when the projector is turned on, STAT=1. Some commands are available only
when specific input sources are active.
Request: *RSRC=4<CR>
Notification: *RSRC=4<CR><LF> (acknowledges request)
*SRC=0<CR><LF> (projector is attempting to acquire
source 4, and in the interim has no valid
source)
*SRC=4<CR><LF> (source 4 is now active)
*BRT=60<CR><LF> (brightness has been modified for
source 4)
*CSPC=?<CR><LF> (color space is not supported for this
input)
