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.

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
.)
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.

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 first 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 verified.
“POWR????”, “TABN _ _ _ 1”, “TLPS _ _ _ 1”, “TPOW _ _ _ 1”, “TLPN _ _ _ 1”, “TLTT _ _ _ 1”,
“TLTM _ _ _ 1”, “TLTL _ _ _ 1”, “TNAM _ _ _ 1”, “MNRD _ _ _ 1”, “PJN0 _ _ _ 1”
² 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.
² The special commands are available for applications that require continuous polling.
