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 you have more than one command to give to the projector, send each of them only after the re-
sponse code for the previous one is received.
• “POWR????” “TABN _ _ _ 1” “TLPS _ _ _ 1” “TLPS _ _ _ 2” “TPOW _ _ _ 1” “TLPN _ _ _ 1” “TLTT _ _ _ 1”
“TLTT _ _ _ 2” “TLTL _ _ _ 1” “TLTL _ _ _ 2” “TNAM _ _ _ 1” “MNRD _ _ _ 1” “SNRD _ _ _ 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
• When controlling the projector using the RS-232C commands, you cannot confirm the projector setting
values from the computer. To confirm each setting value, send the display command for each menu (e.g.
RARE _ _ _ 0), and then refer to the on-screen display. When using the setting/adjustment commands other
than the menu display commands, the settings/adjustments are executed without the on-screen display.
