RS-232C Specifications and Command Settings

Computer 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 27 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 bps	Stop bit: 1 bit
Data length: 8 bits	Flow 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)

	Command 4-digit			Parameter 4-digit
Response		Normal response
code format		O	K	Return code (0DH)

Problem response

(communication error or incorrect command)

E R R Return code (0DH)

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.
