3)Control sequence
(1)Send the command from the personal computer to the projector.
(2)The projector will send a return command after it receives 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 sent command 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 the personal computer.
•During signal switching, the command may not take effect even when the projector sends the return command. After signal switching completes, wait for the mode indication to disappear before sending the next command.
•When sending commands successively, wait to receive the return command of the current command before sending a next command.
•Keep intervals of at least 400 ms between receipt of a return command and sending of a next command.
