Epson Projector Management Connected is configured using the following system.
Epson Projector Management Connected: web service that allows you to monitor and control the status of multiple projectors on your network using a computer connected to the Internet.
Epson Projector Connected Agent: software that communicates between projectors and the Epson Projector Management Connected cloud server.
Projectors: communicate with the server in one of the following ways:
Communicate with the server through the Epson Projector Connected Agent software
Communicate with the server directly, not through the Epson Projector Connected Agent software (applicable models only *)

If you monitor only projectors that support direct communication with the sever, you do not need to use the Epson Projector Connected Agent software.
