HP ep7100 manual Room controller commands, Notification

Installing permanently

■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.

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)

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.
