The following table lists the types of notifications generated in various situations.

This type of request...

Generates this type of notification...

 

 

Modify a setting

Echoes the request command and shows the resulting value:

 

Request: *BRT=65<CR>

 

Notification: *BRT=65<CR><LF>

 

 

Query a setting

Echoes the request command and shows the resulting value:

 

Request: *CON=?<CR>

 

Notification: *CON=40<CR><LF>

 

 

Execute an action

Echoes the request command:

 

Request: *NXT<CR>

 

Notification: *NXT<CR><LF>

 

 

Incorrect commands cause the following types of notifications:

No asterisk at start of command—no response

Unrecognized command name—command with “?” added

Command that is currently unavailable—command with “?” added

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)
