Serial connector
The serial connector complies with RS-232C. To control the projector from a personal computer, com-
mands must be input through communication software, based on the format and satisfying the commu-
nication conditions shown below.
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.

CAUTIION
• 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.
