Basic format
Transmission from the computer begins with STX, then the ID, command, parameter, and ETX are sent
in this order. Add parameters according to the details of control.
CAUTION
• It may not be possible that responses would delay or commands cannot be executed when commands are sent soon after the
light source is 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.
• When using two or more units, set different IDs for each unit.
