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 / 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 40 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 previ- ous command from the projector is verified.

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

When the projector receives a command shown above:

*The on-screen display will not disappear.

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

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.

*1 Serial No. Check command is used to read out the 12 digits of serial No..

*2 For setting the projector name, send the commands in the order of PJN1, PJN2 and PJN3. *3 Parameters of CLR Temp settings are as follows.
