* STX and ETX are character chords. STX is 02 and ETX is 03 when expressed in hexadecimal.

CAUTION

• It may not be possible to send or receive commands for about 10 to 60 seconds when the lamp is first turned on. If this

occurs, wait for 60 seconds, then try sending or receiving again.

• When sending multiple commands, be sure to wait for at least 0.5 second after receiving a response from the projector before

sending the next command.

• Additional time is sometimes required for response due to processing inside the projector. Set the time-out period for com-

mand response to 10 seconds or more.
