*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.
