HP (Hewlett-Packard) ep7100 Series ユーザーズマニュアル

■ 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.

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.

*RSRC=4<CR>

*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)

SRC

?

Queries the current active input source: 
0=no active source, 3=composite video, 
4=S-video, 5=component video, 8=DVI.

RSRC

3,4,5,8,?

Attempts to use the specified source as 
the active input source, or queries the 
last source requested: 3=composite 
video, 4=S-video, 5=component video, 
8=DVI.

NXT

None

Switches to the next input source.
