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 22.)

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

Stop bit: 1 bit

Data length: 8 bits

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.
