This projector can be controlled by connecting a personal computer with RS-232C terminal.
In addition, by connecting multiple projectors to each other in a daisy chain configuration, you can control each 
projector from one personal computer.

 •  Turning the power ON or OFF 
 •  Changing input signals
 •  Inputting commands by pressing the buttons on the control panel and remote control
 •  Menu setting

To  use  the  RS-232C  commands  designed  for  the  former  models  of  Mitsubishi  projector,  by  inputting 
“00COMMAND0”, the projector responds in the same way as the former models. (No NAK is returned. For NAK 
response, see page 4. ID code cannot be designated at command sending.)
(For  the  recommended  procedure  to  use  the  former  command  systems,  see  “Controlling  the  projector  using  a
