In general, every request sent to the projector generates one or more notification
messages, which are sent to the room controller. Actions initiated by the projector
can also generate notifications.
The projector always sends notifications whenever a setting changes, whether as
the result of a request from a controller, or as the result of an action, such as a
button press or menu change. Some requested setting changes take time to
perform, or are carried out in stages. Because of this, requests might produce
delayed notifications.
The following table lists the types of notifications generated in various situations.
This type of request...
Modify a setting
Query a setting

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
