PC control
A computer can be used to control the projector by connecting an RS-232C serial control cable (cross type,
sold separately) to the projector. (See page 54 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 Stop bit: 1 bit
Data length: 8 bits 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 controlling the projector using RS-232C commands from a computer, wait for at least 30 seconds after
the power has been turned on, and then transmit the commands.
•When more than one code is being sent, send each command only after the response code for the previous
command from the projector is verified.
Commands
Example: When turning on the projector, make the following setting.
