The projection screen size varies according to the distance from the lens of the projector to the screen.
Install the projector so that projected images are projected onto the screen at the optimum size by referring
to the table below. Use the values in the table as a reference when installing the projector.

RS-232C Specifications and Commands
Computer control
A computer can be used to control the projector by connecting an RS-232C serial control cable (cross type,
commercially available) to the projector. (See page 27 of the projector’s operation manual for connection.)
Communication conditions
Set the serial port settings of the computer to match that of the table.
Signal format: Conforms to RS-232C standard.Parity bit: None
Baud rate*: 9,600 bps / 115,200 bpsStop bit: 1 bit
Data length: 8 bitsFlow control: None
*Set the projector’s baud rate to the same rate as used by the computer.
Basic format
Commands from the computer are sent in the following order: command, parameter, and return code. After
the projector processes the command from the computer, it sends a response code to the computer.
Command format
C1 C2 C3 C4 P1 P2 P3 P4
Return code (0DH)
Response code format

Info
• When controlling the projector using RS-232C commands from a computer, wait at least 30 seconds after
the power has been turned on, and then transmit the commands. After putting the projector into standby
mode, wait at least 90 seconds until the cooling fan stops, and then transmit the commands.
• If more than one command will be sent to the projector, wait for projector reply before sending next command.
Note
• When the projector receives the following commands, the on-screen display will not disappear and these
commands will not reset the “Auto Power Off” function timer when no signal is present.
