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.

Attention
No command can be sent or received for 10 to 60 seconds after the lamp starts lighting. Try sending any  • 
command after that period has elapsed.
When transmitting multiple commands, be sure to wait until 0.5 seconds has elapsed after receiving the  • 
response from the projector before sending the next command. When sending commands without parameters, 
a colon (:) is not necessary.
Note
When the wrong command is sent, the “ER401” or “ER402” status is sent from the projector to the personal  • 
computer.
Projector ID supported on the RS-232C interface is ZZ (ALL) and a group of 1 to 64 and 0A to 0Z. • 
The “STX” character code is 02 and the “ETX” character code is 03. • 
If a command is sent with a projector ID specified, the projector will return answer back only in the following  • 
cases:
If it coincides with the projector ID
If the ID specification is ALL and responding (ID ALL) is on
If the ID specification is Group and responding (ID Group) is on
Control commands
When controlling the projector from a computer, the following commands are available:
Command Function of command Remarks
