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 24 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 / 38,400 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 code format

Normal response

Problem response (communication error or incorrect command)

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.

•After sending an input selection or picture adjustment command and then receiving an “OK” response code, the projector may take some time to process the command. If a second command is sent while the projector is still processing the ﬁ rst command, you may receive an “ERR” response code. If this happens, try resending the second command.

•When more than one code is being sent, send each command only after the response code for the previous command from the projector is veriﬁ ed.

•“POWR????”, “TABN _ _ _ 1”, “TLPS _ _ _ 1”, “TPOW _ _ _ 1”, “TLPN _ _ _ 1”, “TLTT _ _ _ 1”, “TLTM _ _ _ 1”, “TLTL _ _ _ 1”, “TNAM _ _ _ 1”, “MNRD _ _ _ 1”, “PJN0 _ _ _ 1”

−When the projector receives the special commands shown above:

*The on-screen display will not disappear.

*The “Auto Power Off” timer will not be reset.

−The special commands are available for applications that require continuous polling.

Note

•If an underbar (_) appears in the parameter column, enter a space.

•If an asterisk (*) appears in the parameter column, enter a value in the range indicated in brackets under Control Contents.
