Note
f The projector automatically disconnects from the network immediately after sending the command. Such specications are made from the
viewpoint of security, such as prevention of illegal operation of the projector by a malicious third party. To send commands continuously,
make a request for network connection every time and send it. For details, see “Communication ow between the server and the client”
(x page 148).
