f The projector automatically disconnects from the network immediately after sending the command. Such specifications 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 flow between the server and the client"
(x page 169).
