Example — changing input source

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=2<CR>

Notifications: *RSRC=2<CR><LF> (acknowledges request)

*SRC=0<CR><LF> (projector is attempting to

acquire source 2, and in the

interim has no valid source)

*SRC=2<CR><LF> (source 2 has been acquired

and is now active)

*BRT=50<CR><LF> (brightness has been modified

for source 2)

*CSPC=?<CR><LF> (color space is not supported

for this input)

Example — changing the picture mode

A request to change the picture mode can take a moment to complete, and so produces

a delayed notification. In this example, the picture mode is initially set to 0.

Request: *PMOD=1<CR>

Notifications: *PMOD=0<CR><LF> (current setting)

*PMOD=1<CR><LF> (new mode is active)

Example — turning on the projector

Request: *STAT=?<CR>

Notification: *STAT=0<CR><LF> (current setting)

Request: *W<CR>

Notifications: *W<CR><LF> (echoes request)

*STAT=2<CR><LF> (projector enters its warm-up

state)

*STAT=1<CR><LF> (projector enters its on state)
