Basic format
Transmission from the computer starts with STX, then the ID, command, parameter, and ETX are sent in this
order. Add parameters according to the details of control.

*1 When transmitting a command which does not need a parameter, the operation (E) and parameter are not necessary.
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.
Note
f
If a command cannot be executed, the “ER401” response is sent from the projector to the computer.
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 specified ID, a response will be sent to the computer only in the following cases.
- It matches the projector ID
- When [PROJECTOR ID] (
x
page 87) on the projector is [ALL]
f
STX and ETX are character codes. STX shown in hexadecimal is 02, and ETX shown in hexadecimal is 03.
