PC control
A computer can be used to control the projector by connecting an RS-232C cable (null modem, cross type,
commercially available) to the projector. (See page 23 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.
Baud rate: 9,600 bps
Data length: 8 bits
Parity bit: None
Stop bit: 1 bit
Flow control: None
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.
Info
• When more than one code is being sent, send each command only after the OK response code for the
previous command from the projector is verified.
Note
• When using the computer control function of the projector, the projector’s operating status cannot be read by
the computer. Therefore, confirm the status by transmitting the display commands for each adjustment
menu and checking the status with the on-screen display.
Commands
Example:
• When power on.
