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.
• If more than one command will be sent to the projector, wait for projector reply before sending next com-
mand.
Note
• Use "POWR????" and "TLPS___1" for projector polling.
• When the projector receives these commands, the on-screen display will not disappear and these com-
mands will not reset the "Auto Power Off" function timer when no signal is present.
