Try sending or receiving any command after 60 seconds.f When transmitting multiple commands, be sure to wait until 0.5 seconds has elapsed after receiving the response from theprojector before sending the next command. When transmitting a command which does not need a parameter, a colon (:) isnot necessary.Notef If a command cannot be executed, the “ER401” response is sent from the projector to the computer.f If an invalid parameter is sent, the “ER402” response is sent from the projector to the computer.f ID transmission in RS-232C supports ZZ (ALL) and 01 to 06.f If a command is sent with a specified ID, a response will be sent to the computer only in the following cases.- It matches the projector ID.- [PROJECTOR ID] (x page 78) is set to [ALL].f STX and ETX are character codes.
