RS-232C Specifications and Command Settings

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 24 for connection.)

Communication conditions

Set the serial port settings of the computer as follows.

Signal format: Conforms to RS-232C standard.

Parity bit: None

Baud rate*: 9,600 bps / 38,400bps / 115,200bps

Stop bit: 1 bit

Data length: 8 bits

Flow control: None

*Use the same settings for the projector and computer.

 

Basic format

Send commands from the computer in the following order: command, parameter, and return code. After processing the command from the computer, the projector sends a response code to the computer.

Info

•If you are controlling the projector from a computer using RS-232C commands, wait at least 30 seconds after turning the projector on before sending any commands.

•When more than one code is being sent, send each command only after the response code for the previ- ous command from the projector is verified.

•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: To turn on the projector
