RS-232C Specifications and Commands Computer control A computer can be used to control the projector by connecting an RS-232C serial control cable (cross type, commercially available) to the projector. (See page 27 of the projector's operation manual 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 Response code format Normal response Parameter 4-digit Problem response (communication error or incorrect command) O K Return code (0DH) 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. • If more than one command will be sent to the projector, wait for projector reply before sending next command. Note • Use "POWR????" and "TLPS___1" for projector polling. • When the projector receives these commands, the on-screen display will not disappear and these com- mands will not reset the "Auto Power Off" function timer when no signal is present. Commands Example: When turning on the projector, make the following setting.
