Mitsubishi X70bu Projector User Manual

							2 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 sending time of return command may delay depending on the condition (during changing the
input signal, etc.).
[Example] Turn the power ON (  is for ASCII code)

 carrired out
When a personal computer sends the command, data code will not be attached. On the other hand, the projector
which has received a command will attach the recent operating status and then send.
[Example ]  Input  was Video when the operating status of the input terminal was confirmed.
8) Menu setting commands
The menu setting commands execute the menu setting of this projector. If the personal computer doesn’t send
the commands without attaching the data code, the projector which has received the command replays the
setting data as data code.
