3) Control sequence
(1) Send the command from a personal computer to the projector. (The commands must be sent at least
400ms apart.)
(2) The projector will send a return command 400ms* after it has received an end code. If the command is
not received correctly, the projector will not send the return command.
(3) The personal computer checks the command and confirms if the command which has been sent has been
executed or not.
(4) This projector sends various codes other than the return code. When having a control sequence by RS-
232C, reject other codes from personal computer side.
• The first character of the Status code from projector may not be displayed correctly. In this case, reject the
first character on the computer side.
• * : The sending time of return command may delay depending on the condition (during changing the
input signal, etc.).
