• 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 do not require parameters is 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.

• If an incorrect parameter is sent from the personal computer, the “ER402” command will be sent from the projector to

the personal computer.
