The projector can not receive any command for 10 seconds after the lamp is switched on. Wait 10 seconds before sending the command.
If sending multiple commands, check that a response has been received from the projector for one command before sending the next command.
When a command which does not require parameters to be sent, the colon (:) is not required.
If an incorrect command is sent from the personal computer, the ER401 command will be sent from the projector to the personal computer.
