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 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 response code for the previous
command from the projector is verified.
•In the case of transmitting commands during standby, it takes a maximum of 30 seconds until the response
code is received.
•When the power is turned on during standby with the “POWER ON” command, wait for at least 30 seconds
after the power has been turned on, and then transmit the next command.
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. If the projector receives a command other than a
menu display command, it will execute the command without displaying the on-screen display.
Commands
Example:
• When “BRIGHT” of INPUT 1 image adjustment is set to –10.
