Attention
f If a command is transmitted after the luminous lamp starts illuminating, there may be a delay in response or the command may not be
executed. Try sending or receiving any command after 60 seconds.
f 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 transmitting a command which does not need a parameter, a colon (:) is not necessary.

f If an invalid parameter is sent, the “ER402” response is sent from the projector to the computer.
f ID transmission in RS-232C supports ZZ (ALL) and 01 to 06.
f If a command is sent with a specied ID, a response will be sent to the computer only in the following cases.
- It matches the projector ID
