HP xp8000 HP xp8000 series digital projector - RS232 Protocol Reference - Page 9

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 Notifications: *RSRC=2 (acknowledges request) *SRC=0 (projector is attempting to acquire source 2, and in the interim has no valid source) *SRC=2 (source 2 has been acquired and is now active) *BRT=50 (brightness has been modified for source 2) *CSPC=? (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 Notifications: *PMOD=0 (current setting) *PMOD=1 (new mode is active) Example - turning on the projector Request: *STAT=? Notification: *STAT=0 Request: *W Notifications: *W *STAT=2 *STAT=1 (current setting) (echoes request) (projector enters its warm-up state) (projector enters its on state) RS-232 protocol reference 9
