Basic format

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.
