Mitsubishi Electronics LVP-X400U Control sequence, Operation commands, Computer input commands

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 maybe delayed depending on the condition (during changing the input signal, etc.).
